title: Transhepatic embolization of varices.
abstract: Percutaneous transhepatic embolization of varices (PTEV) has proved to be effective in the control variceal bleeding, particularly in Child's Class C Category patients whose bleeding was not adequately controlled by pitressin perfusions. PTEV, using Gel-Foam soaked in sodium tetradecyl sulfate, controlled acute variceal bleeding in 71--95% of patients and appears to be more effective as an embolizing agent than bucrylate, which controlled 43--57%. Considering the poor condition of the patients particularly during acute bleeding episodes, PTEV is a relatively safe therapeutic procedure that buys time for the surgeons to perform a decompressive shunt electively as definitive surgery. A one-year recurrent bleeding rate of 30% and a two year recurrence of 37.5% was noted. Thus, for long term control of variceal bleeding, a surgical decompressive shunt is recommended in addition to PTEV.
