[Mesenteric vein thrombosis after devasculation for portal hypertension]
Abstract:
Six patients with mesenteric vein thrombosis (MVT) after devasculation for portal hypertension were treated by intestinal resection. Two patients had recurrence of thrombosis after the initial operations. Among 6 patients 2 survived and 4 (66.7%) died. MVT is an underappreciated, patentially lethal complication after revasculation. Three pathogenic factors after the operation may lead to thrombus formation of the portal vein, portal congestion, hypercoaguble state, and extensive ligation of portal branches. The complication commonly occurs in the recent period after devasculation. It is a characteristic manifestation of MVT that abdominal pain is out of proportion to physical findings. The most effective method is resection of infarcted bowel with sufficient length of normal bowel and its mesentery. In order to avoid a recurrence of thrombosis, postoperative anticoagulation treatment should be given.
Insights
Mesenteric vein thrombosis (MVT) is a dangerous complication following portal hypertension surgery. Early detection and surgical resection of affected bowel, followed by anticoagulation, are crucial for survival.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Hepatology
Context:
- Mesenteric vein thrombosis (MVT) is a severe complication following surgical revascularization procedures for portal hypertension.
- This condition can lead to significant morbidity and mortality if not promptly addressed.
Purpose:
- To analyze the outcomes of intestinal resection in patients who developed MVT after revascularization for portal hypertension.
- To identify pathogenic factors contributing to MVT and to recommend management strategies.
Summary:
- Six patients with MVT post-revascularization underwent intestinal resection; 2 survived, and 4 died (66.7% mortality).
- Recurrence of thrombosis occurred in two patients.
- Key factors for thrombus formation include portal congestion, hypercoagulable state, and extensive portal branch ligation.
- Abdominal pain disproportionate to physical findings is characteristic of MVT.
- Effective treatment involves resection of infarcted bowel with adequate margins.
Impact:
- Highlights MVT as an underappreciated and potentially lethal complication of portal hypertension surgery.
- Emphasizes the importance of postoperative anticoagulation to prevent thrombosis recurrence.
- Informs surgical decision-making and postoperative care protocols for patients at risk of MVT.
