Gastrointestinal Hemorrhage from Adhesion-related Mesenteric Varices

Abstract

As a result of this retrospective analysis of hemorrhage from a porta-systemic venous shunt occurring within the small intestine, we believe that the early diagnosis of the syndrome is strongly suggested by the presence of varices in unusual locations demonstrated by the venous phase of mesenteric arteriography. In all patients portal hypertension was present, and in all the affected bowel was adherent to postoperative adhesions on old suture lines. The syndrome was treated variously with lysis of adhesions, bowel resection, or portal-systemic shunt. Those patients with excellent hepatic reserve survived and had no further gastrointestinal bleeding.

Two Cases of Hemodialysis-associated Chronic Portal-systemic Shunt Encephalopathy (CPSE) with Opposite Changes in the Blood Ammonia Concentrations during Hemodialysis: A Case Report and Literature Review

“…Recently, CPSE has been recognized to be a cause of disturbance of consciousness in patients receiving dialysis (3)(4)(5)(6). Dialysis patients may develop CPSE for several reasons, including the growth of PSS due to fluid overload and an increase in back flow via the PSS as a result of hemodialysis-related fluid removal (7)(8)(9).…”

Duodenal and jejunal varices due to superior mesenteric vein thrombosis presenting as a massive gastrointestinal tract bleeding: a case report

“…These types of varices are associated with intraabdominal adhesions, especially post-operative ones [8,9]. In one case series, four patients with GITB due to trans-anastomotic portoportal varices were reported; all of these patients had a previous history of abdominal surgery, and all four anastomotic varices resulted in lower gastrointestinal bleeding [10].…”

Stent placement is effective on both postoperative hepatic arterial pseudoaneurysm and subsequent portal vein stricture: A case report

“…In cases of varices generated in the intestines, extrahepatic portal obstruction often plays a causative role [9] . Jejunal varices caused by portal venous obliteration could be treated with either a shunt for portal decompression [10,11] , an angioplasty by an IVR technique such as balloon dilation, stenting to correct the portal blood flow [12] or embolizing varices by an IVR technique to stop inflow [13,14] .…”
