PURPOSE: To investigate, by transhepatic portography, the changes in portosystemic collaterals and recurrent esophagogastric varices after devascularization surgery.
METHODS: Thirty-five patients, who had undergone devascularization surgery 2-8 years previously, underwent follow-up portography and the collaterals and drainage routes were compared with preoperative portography results.
RESULTS: Newly formed collaterals were present in 30 of 35 patients and the origins and drainage routes differed from preoperative ones. Most common were new collaterals arising from the junction of the portal and superior mesenteric veins; the next most frequent arose from a main portal branch, the portal trunk, or the superior mesenteric vein. New collaterals with recurrent varices were seen in 20 patients and without varices in 10; 5 patients had no collaterals or varices.
CONCLUSION: Since the development of new collaterals is common in portal hypertensive patients following devascularization surgery, regular follow-up for recurrent varices is necessary.
