Portal Hypertension

What Is Portal Hypertension?

Portal hypertension is abnormally elevated pressure in the portal vein and its branches, the vessels that carry blood from the digestive organs to the liver. A portal venous pressure gradient above 10 mmHg is associated with clinically significant complications; above 12 mmHg, the risk of variceal bleeding begins. It is not a disease in itself but a consequence of another condition, most commonly liver cirrhosis , though in India it is also frequently caused by extrahepatic portal vein obstruction (EHPVO), which occurs in patients with perfectly normal liver function.

The most dangerous complication of portal hypertension in Delhi and across India is variceal bleeding: the rupture of swollen veins in the oesophagus or stomach (varices) that form when portal blood, unable to flow freely through the liver, seeks other routes. Variceal haemorrhage carries a mortality risk of 15 to 25 percent per episode if not treated promptly and expertly. Other major complications include ascites (fluid accumulation in the abdomen), hepatic encephalopathy, hypersplenism and spontaneous bacterial peritonitis.

At Liver Surgeons , portal hypertension treatment in Delhi is led by Dr. Ashish George , a specialist liver transplant and HPB surgeon at Fortis Hospital, Shalimar Bagh, with 18 or more years of experience in the full spectrum of portal hypertension surgery, from emergency variceal bleeding to elective shunt procedures and liver transplant.

Portal Hypertension Surgery in Delhi

Complete treatment for portal hypertension, variceal bleeding and related complications

What Causes Portal Hypertension?

The cause of portal hypertension determines the right treatment. Our team establishes the exact cause before recommending surgery.

Intrahepatic (Within the Liver): Most Common in Adults With Cirrhosis

  • Liver cirrhosis: The most common cause worldwide, from alcohol, viral hepatitis B and C, fatty liver disease (MASH) and autoimmune hepatitis.
  • Non-cirrhotic intrahepatic portal hypertension (NCPH): Hepatic fibrosis without cirrhosis, which is particularly important in India.

Prehepatic: Important in India, Especially in Children

  • Extrahepatic portal vein obstruction (EHPVO): Thrombosis or cavernous transformation of the portal vein. Liver function is often completely normal. It is the most common cause of portal hypertension in Indian children.
  • Splenic vein thrombosis: Causes isolated gastric varices and is treated by splenectomy alone.

Posthepatic: Obstruction Above the Liver

  • Budd-Chiari syndrome: Hepatic vein obstruction treated with TIPS, surgical shunts or liver transplant depending on acuity and stage.
  • Right heart failure and constrictive pericarditis: Cardiac causes of elevated hepatic venous pressure.

When Is Surgical Treatment of Portal Hypertension Needed?

Most patients with portal hypertension are first managed with medications (non-selective beta-blockers) and endoscopic therapy (variceal band ligation or sclerotherapy). Surgical treatment of portal hypertension is considered when:

  • Variceal bleeding cannot be controlled by endoscopy or recurs despite it. This is the most common indication for portal hypertension shunt surgery in Delhi.
  • TIPS is not possible or has failed. Shunt surgery provides durable long-term decompression in patients who cannot have or have failed a TIPS procedure.
  • Extrahepatic portal vein obstruction (EHPVO) with thrombosed portal system. Surgical devascularisation or Rex shunt is the treatment of choice for EHPVO patients who are not candidates for TIPS.
  • Refractory ascites with preserved liver function. Selected patients benefit from surgical or TIPS decompression before liver transplant is needed.
  • End-stage liver disease with portal hypertension. Liver transplant is the only treatment that corrects both the liver disease and portal hypertension simultaneously.
Important: Portal hypertension shunt surgery should only be performed in patients with adequate residual liver function (Child-Pugh A or selected Child-Pugh B). Patients with Child-Pugh C liver disease or advanced cirrhosis are generally better served by liver transplant evaluation than by shunt surgery. Our multidisciplinary team reviews every patient's full picture before recommending any surgical approach.

Portal Hypertension Shunt Surgery and Other Treatments: Complete Guide

The table below covers every treatment available for portal hypertension at our Delhi centre, from minimally invasive TIPS to portal hypertension shunt surgeries, devascularisation and liver transplant.

Procedure Type When Used Key Benefit
TIPS (Transjugular Intrahepatic Portosystemic Shunt) Minimally invasive radiological Acute variceal bleeding; bridge to transplant; refractory ascites No open surgery; fast decompression; reversible stent
Distal splenorenal shunt (Warren shunt) Selective surgical shunt First-choice surgical shunt in cirrhotic portal hypertension with preserved liver function Selective; preserves portal flow to the liver; lowest encephalopathy risk among surgical shunts
Proximal splenorenal shunt Total surgical shunt When distal shunt anatomy is not feasible; combined with splenectomy Full decompression plus hypersplenism control through splenectomy
Mesocaval shunt Total surgical shunt Unfavourable splenorenal anatomy; Budd-Chiari syndrome Good alternative when splenic vessels are not suitable
Rex shunt (mesenterico-left portal bypass) Physiological surgical shunt Children and young adults with EHPVO (extrahepatic portal vein obstruction) Restores physiological portal flow to the liver; no encephalopathy; no liver transplant required
Devascularisation and splenectomy (Hassab or modified Sugiura procedure) Non-shunt surgical procedure Thrombosed portal system where no vein is suitable for shunt; selected EHPVO and complex cases Controls variceal bleeding without a shunt; particularly relevant in India
Liver transplant Curative for end-stage disease End-stage liver disease with portal hypertension; after failed shunt or TIPS Only treatment that corrects both the liver disease and portal hypertension simultaneously
Our approach: No single treatment suits every patient. TIPS, shunt surgery and devascularisation are complementary tools, not competing ones. The right choice depends on the cause of portal hypertension, the degree of liver function impairment, the anatomy of the portal venous system and whether the patient will eventually need a liver transplant. We review all these factors together before recommending any procedure.

TIPS for Portal Hypertension in Delhi

TIPS stands for Transjugular Intrahepatic Portosystemic Shunt. It is a minimally invasive procedure performed by an interventional radiologist, in which a metal stent is placed through the jugular vein in the neck, tracked through the hepatic vein into the liver, and used to create a channel between the portal and hepatic veins inside the liver parenchyma. This channel bypasses the high-resistance diseased liver tissue and reduces portal pressure.

  • Main uses in our Delhi programme: Acute variceal bleeding not controlled by endoscopy; refractory ascites; bridge to liver transplant.
  • Advantage: No open surgery required; can be performed in emergency settings; reversible if needed.
  • Limitation: Hepatic encephalopathy occurs in 20 to 35 percent of patients after TIPS; shunt stenosis or occlusion requires re-intervention; not suitable for patients with severe liver failure or cardiac disease.
  • Who performs TIPS at our centre: Our interventional radiology team in collaboration with Dr. Ashish George's hepatology and transplant programme.

Portal Hypertension Shunt Surgery in Delhi

Portal hypertension shunt surgery creates a direct surgical connection between the high-pressure portal venous system and the low-pressure systemic venous system, diverting blood away from the oesophageal and gastric varices. In experienced hands, surgical shunts provide the most durable long-term relief from variceal bleeding among all available portal hypertension shunt treatments. A 2023 Chinese study found five-year freedom from variceal rebleeding of 80 percent with TIPS and 95 percent with surgical devascularisation plus splenectomy in cirrhotic patients, and superior long-term survival in the surgical group.

Distal Splenorenal Shunt (Warren Shunt): Our First-Choice Surgical Shunt

The distal splenorenal shunt connects the distal end of the splenic vein to the left renal vein. It is a selective shunt: it decompresses the oesophageal and gastric varices while preserving portal blood flow to the liver, maintaining liver function better than total shunts. It carries a lower risk of hepatic encephalopathy than proximal or mesocaval shunts. This is our preferred surgical shunt for eligible cirrhotic patients with good hepatic reserve.

Proximal Splenorenal Shunt

The proximal splenorenal shunt connects the splenic vein at the hilum of the spleen to the left renal vein, combined with splenectomy. It produces total portal decompression rather than selective decompression. It is used when the distal shunt is not anatomically feasible and has the added benefit of eliminating hypersplenism through splenectomy.

Mesocaval Shunt

The mesocaval shunt connects the superior mesenteric vein to the inferior vena cava, either directly or through an interposition graft. It is used when the splenic and renal veins are not suitable for a splenorenal shunt, in cases of Budd-Chiari syndrome and in selected emergency situations.

Rex Shunt (Mesenterico-Left Portal Bypass) for EHPVO

The Rex shunt is a physiological restoration procedure rather than a decompressive shunt. It connects the superior mesenteric vein to the left portal vein, restoring normal portal blood flow to the liver in patients with extrahepatic portal vein obstruction (EHPVO). It is the treatment of choice for children and young adults with EHPVO and a patent left portal vein. Unique among all shunt surgeries for portal hypertension, it carries essentially no risk of hepatic encephalopathy because it restores the normal direction of flow rather than diverting blood away from the liver.

Devascularisation and Splenectomy for Portal Hypertension

Devascularisation procedures control variceal bleeding by interrupting the blood supply to the oesophageal and gastric varices rather than by decompressing the portal system. They are used when the portal and splenic veins are thrombosed and no suitable vein is available for a shunt anastomosis. The standard procedure in India is the Hassab procedure or modified Sugiura devascularisation: splenectomy combined with gastroesophageal devascularisation, covering the upper two thirds of the stomach and the lower oesophagus.

Why devascularisation is particularly important in India: Extrahepatic portal vein obstruction (EHPVO) is significantly more common in India than in Western countries, and EHPVO patients frequently have thrombosed portal systems unsuitable for conventional shunts. Indian HPB surgeons, including our Delhi team, have extensive experience with devascularisation for EHPVO that most Western centres cannot match. The rebleeding rate with a well-executed devascularisation at an experienced Indian centre is approximately 15 to 25 percent, better than the global average and comparable to TIPS in this specific population.

Portal Hypertension Complications and How We Treat Them in Delhi

The right portal hypertension treatment at our Delhi centre is always matched to the specific complication a patient is presenting with. The table below shows our approach:

Complication Surgical or Procedural Treatment at Our Delhi Centre
Acute variceal bleeding not controlled by endoscopy Emergency TIPS; Sengstaken-Blakemore balloon tamponade as a bridge; surgical shunt in selected cases with good liver function
Recurrent variceal bleeding after endoscopic therapy Elective portal hypertension shunt surgery (distal splenorenal shunt as first choice) or TIPS as a bridge to transplant
Refractory ascites not responding to diuretics TIPS; paracentesis with albumin replacement; evaluation for liver transplant
Hypersplenism (low platelets and white cells) Splenectomy as part of a proximal splenorenal or devascularisation procedure
Extrahepatic portal vein obstruction (EHPVO) in children or adults Rex shunt (mesenterico-left portal bypass) where the left portal vein is patent; devascularisation where it is not
End-stage liver disease with portal hypertension Liver transplant evaluation; see our living donor liver transplant and deceased donor liver transplant pages

Best Portal Hypertension Doctor, Surgeon and Hospital in Delhi

Portal hypertension surgery is not routine surgery. The decision between TIPS, surgical shunt and devascularisation requires expertise in hepatology, interventional radiology and HPB surgery, ideally under one roof. When choosing a portal hypertension doctor in Delhi or a portal hypertension shunt hospital in Delhi, look for:

  • All treatment modalities available in one programme. A centre that can offer TIPS, all surgical shunt types, devascularisation, Rex shunt and liver transplant avoids the risk of patients being offered only what a single surgeon or department can do, rather than what is right for them.
  • Experience with non-cirrhotic portal hypertension and EHPVO. This is particularly important in India, where EHPVO is common and requires surgical expertise most Western-protocol centres lack.
  • Emergency capability. Variceal bleeding is a surgical emergency. A portal hypertension shunt hospital in Delhi needs 24/7 interventional radiology for TIPS and an on-call surgical team for emergency shunt or devascularisation.
  • Multidisciplinary liver disease programme. Portal hypertension patients who have underlying cirrhosis may eventually need liver transplant. A centre that manages both portal hypertension surgery and transplant avoids a dangerous gap in long-term care.
  • High volume of portal hypertension cases. Shunt anastomoses and devascularisation require meticulous technique. Surgical outcomes improve significantly with centre and surgeon volume.

Dr. Ashish George 's portal hypertension programme at Fortis Hospital, Shalimar Bagh in Delhi covers every aspect of this condition: TIPS in collaboration with our interventional radiology team, all surgical shunt types including the Rex shunt for EHPVO, Hassab devascularisation and splenectomy, and liver transplant for end-stage disease.

As a specialist who manages both portal hypertension surgery and liver transplantation at the same centre, Dr. George is uniquely positioned to give patients an honest assessment of whether surgery, TIPS or transplant evaluation is the right next step. For broader guidance, see our blog on how to find the best liver transplant surgeon in Delhi .

Portal Hypertension Surgery Outcomes at Our Delhi Centre

The outcomes below are consistent with published high-volume data for portal hypertension surgery in India and internationally:

  • Distal splenorenal shunt (Warren shunt): Rebleeding rate approximately five to ten percent at five years in well-selected patients; hepatic encephalopathy rate ten to fifteen percent (lower than total shunts).
  • Devascularisation and splenectomy (Hassab procedure): Rebleeding rate fifteen to twenty-five percent in experienced hands; particularly effective for EHPVO; survival around ninety percent at two years.
  • Rex shunt (for EHPVO in children and young adults): Patency rates above eighty percent at five years in high-volume centres; essentially zero hepatic encephalopathy; variceal resolution in over ninety percent.
  • TIPS: Excellent control of acute variceal bleeding and ascites; five-year shunt patency dependent on covered stent use (above seventy percent with covered stents); encephalopathy in twenty to thirty-five percent of patients.
Note: Outcomes vary significantly based on the patient's liver function (Child-Pugh and MELD score), the cause of portal hypertension, the surgeon's experience and the appropriateness of patient selection. Individual outcomes are discussed in full during your consultation with Dr. Ashish George.

Frequently Asked Questions

Treatment depends on the cause and the specific complication. It ranges from medications (beta-blockers) and endoscopic variceal band ligation as first-line management, through TIPS (a minimally invasive radiological procedure) and portal hypertension shunt surgery, to liver transplant for end-stage cirrhosis. At our Delhi centre, all these treatments are available in a coordinated multidisciplinary programme.

Portal hypertension shunt surgery creates a surgical connection between the high-pressure portal venous system and the low-pressure systemic venous system, diverting blood away from oesophageal and gastric varices. The main types are the distal splenorenal shunt (Warren shunt), proximal splenorenal shunt, mesocaval shunt and Rex shunt (for EHPVO). These are performed as open operations at our Delhi centre.

Look for a surgeon with experience in all types of shunt surgery (not just one technique), expertise in non-cirrhotic portal hypertension and EHPVO, access to TIPS through an interventional radiology team, and the ability to evaluate for liver transplant when needed. At Liver Surgeons, Dr. Ashish George manages the full spectrum of portal hypertension surgery at Fortis Hospital, Shalimar Bagh, Delhi.

The best portal hypertension shunt hospital in Delhi has all treatment modalities available: TIPS through interventional radiology, full surgical shunt capability, devascularisation experience, Rex shunt for EHPVO, and liver transplant for end-stage disease. Fortis Hospital, Shalimar Bagh, where Dr. Ashish George practices, meets all these criteria.

Neither is universally better; they suit different patient groups. TIPS is preferred for acute variceal bleeding, refractory ascites and patients who are likely to need liver transplant (as TIPS does not complicate transplant surgery). Surgical shunt surgery is preferred for younger patients with good liver function who need long-term durable control of variceal bleeding, especially if they are not transplant candidates. Both options are reviewed for every patient at our weekly multidisciplinary case conference.

Devascularisation surgery (Hassab or modified Sugiura procedure) controls variceal bleeding by interrupting the blood supply to the varices rather than creating a shunt. It is used when the portal and splenic veins are thrombosed and no suitable vein is available for a shunt anastomosis. It is an important procedure in India because extrahepatic portal vein obstruction (EHPVO), which often presents with a thrombosed portal system, is more common in India than in the West.

Extrahepatic portal vein obstruction (EHPVO) is thrombosis or cavernous transformation of the portal vein, causing portal hypertension in patients whose liver function is often completely normal. It is the most common cause of portal hypertension in Indian children. Surgical treatment depends on the anatomy: where the left portal vein is patent, the Rex shunt (mesenterico-left portal bypass) restores physiological portal flow with excellent long-term results. Where no suitable vein exists for a shunt, devascularisation and splenectomy controls variceal bleeding. Dr. Ashish George's Delhi team has extensive experience with both approaches.

Surgical shunts and devascularisation control the complications of portal hypertension, particularly variceal bleeding, but do not cure the underlying cause (such as cirrhosis). The only treatment that simultaneously treats both the liver disease and the portal hypertension is liver transplant, which is indicated for end-stage liver disease. For patients with EHPVO and normal liver function, the Rex shunt is as close to a cure as any portal hypertension surgery can offer. See our liver transplant pages for more on transplant options.

Portal hypertension shunt surgery and devascularisation are safe procedures at high-volume experienced centres. The principal risks are hepatic encephalopathy (particularly with total shunts such as the proximal splenorenal or mesocaval shunt), shunt occlusion requiring re-intervention and general surgical risks including bleeding and infection. Operative mortality in elective portal hypertension surgery is below five percent in Child-Pugh A patients at experienced centres.

Untreated portal hypertension progressively worsens. Each episode of variceal bleeding carries a fifteen to twenty-five percent mortality risk. Repeated bleeding episodes cause increasing liver deterioration. Ascites, hepatic encephalopathy, spontaneous bacterial peritonitis and hypersplenism develop over time. Early specialist review by a portal hypertension doctor in Delhi is essential to prevent these life-threatening complications.
