Role of percutaneous transhepatic obliteration of varices in the management of hemorrhage from gastroesophageal varices.

One hundred and forty-one attempts at percutaneous transhepatic variceal obliteration were made in 116 patients with portal hypertension complicated by variceal hemorrhage. Varices were successfully obliterated in 80% of procedures and included 37 patients with continuous, acute variceal hemorrhage. Hemorrhage ceased immediately in these patients. Sixty-five percent of patients rebled a mean of 4.6 mo after successful transhepatic variceal obliteration. A randomized controlled trial against conventional medical therapy (29 treatment, 25 control) failed to show a significant reduction in death rate after transhepatic sclerotherapy, although the onset of further variceal hemorrhage was delayed. Follow-up portography in 50 patients demonstrated new vessel formation in 38 patients and recanalization of previously occluded varices in 5 patients. Complications arose in 29 of 141 procedures. There was one death but all the other complications responded to conservative management. Transhepatic variceal obliteration is an excellent, safe emergency treatment for variceal hemorrhage, especially in patients with decompensated liver disease. A high incidence of rebleeding is a long-term disadvantage and means that transhepatic variceal obliteration should not be used for the prophylaxis of variceal hemorrhage. Successful emergency treatment of variceal hemorrhage should be followed by elective portal decompression in suitable patients.
