To list a few, our section of Interventional Radiology specializes in the following procedures:

Balloon-Occluded Retrograde Transvenous Obliteration (BRTO): Since its introduction in the mid-1990s, balloon-occluded retrograde transvenous obliteration (BRTO) has become widely accepted in countries such as Japan as a minimally invasive, highly effective treatment for gastric varices. It is an effective treatment option for portal-systemic encephalopathy secondary extrahepatic portal-systemic shunts, including gastro-renal, spleno-renal, and mesenteric-renal shunts in patients with and without liver cirrhosis. Although, its use in India is not widely popular, ILBS is amongst the very few centers where the procedure is being frequently performed with excellent clinical outcomes. The multidisciplinary team at ILBS consisting of the Hepatologist and Interventional Radiologists is proud to have performed one of the highest number of BRTO procedures in the country.

Trans-Jugular Intra-hepatic Porto-systemic Shunt (TIPS): TIPS is a procedure wherein an interventional radiologist creates an artificial channel within the liver between the inflow portal vein and the outflow hepatic vein so as to treat portal hypertension associated with unrelenting GI-bleed or ascites. This procedure becomes life saving in the setting of uncontrolled variceal bleed.

The procedure requires high expertise and is being performed at meager number of institutes across the country. However, we are fortunate to have performed 31 procedures in the year 2012 with majority of patients showing good post procedural results. Of these, 15 of them were performed on an emergency basis as a life-saving procedure to arrest catastrophic upper GI bleed from gastro-esophageal varices in patient with liver cirrhosis.

radiology

Trans-arterial chemo Embolization (TACE): TACE is a treatment that combines the blocking (embolisation) of the blood supply to liver tumor with an embolic material (with lipiodol or drug-eluting microspheres DE-beads) and delivery of chemotherapy directly into the blood vessels which supply the liver tumour. Even in cases where chemoembolization is not curative, this approach may relieve a patient's symptoms and extend survival. We performed TACE in 62 patients in the past 12 months.

Radiofrequency Ablation (RFA): Interventional radiology techniques of applying heat to tumors as a means of killing cancer cells is been in clinical use since past couple of years. However, this type of treatment, called tumor ablation, is a relatively new technique for opening biliary stents which get blocked by tumor in-growth. This novel and innovative technology is now being routinely performed at ILBS and has been shown to offer promising palliative results for treating advanced biliary cancer (cholangiocarcinoma).

New Services and Facilities added

World class Myrian French liver volumetry software was incorporated into existing MDCT and MRCP scans, to provide MEVIS like in-house reformats for the liver transplant workup. On site training at Paris was also given to faculty regarding operations of the same.

Liver volumetry software Myrian™ XP-Liver uses unique segmentation algorithms to isolate entire hepatic vascular systems, healthy parenchyma and lesions and calculate their volume with high precision. It generates highly accurate, dependable and reproducible measurements, as well as three-dimensional images which facilitate interdepartmental communication. This software has set new standards in decision-making for living donor liver transplant surgery and interventional radiology procedures.

Balloon-Occluded Retrograde Transvenous Obliteration (BRTO):

This procedure was introduced in the mid-1990s in Japan and is being practiced mostly in Asian subcontinent. It is a minimally invasive, highly effective treatment for gastric varices. It is an effective treatment option for portal-systemic encephalopathy secondary to extrahepatic portalsystemic shunts. Although, its use in India is not widely popular, ILBS is amongst the very few centers where the procedure is being frequently performed with excellent clinical outcomes. The multidisciplinary team at ILBS consisting of the Hepatologist and Interventional Radiologists is proud to have performed one of the highest number of BRTO procedures in the country.

Per-cutaneous trans hepatic antegrade gastro/lienorenal shunt occlusion:Large spontaneous porto-systemic shunts in the setting of liver cirrhosis may sometimes lead to recurrent severe hepatic encephalopathy. Patients who do not respond to medical management require closure of these shunts. Patients with complex venous vascular anatomy may require percutaneous access of portal vein and further cannulation of the shunt and closure of the same. A rare and challenging procedure which our team has succesfully performed in few cases.

TIPS shunt reduction:Hepatic encephalopathy is the most common complication seen in patients with TIPS. Those patients having recurrent severe hepatic encephalopathy require either closue or reduction of TIPS shunt. While closure of the shunt may lead to recurrence of the symptom (UGI bleed / Ascites), reduction of the shunt remains the most reasonable treatment. Although challenging task but our interventional team has done few of these procedures using novel parallel stent technique.

Transjugular renal biopsy: Renal biopsy is one of the most important invstigation for a nephrologist to determine appropriate therapy. However percutaneous biopsy may be risky in patients with low platelet count and increased prothrombin time (specially in patients with liver cirrhosis) and in such cases biopsy may be safely performed via jugular route. Our institute is amongst few to initiate and perform this procedure on regular basis.
