Delayed Development of a Traumatic Superior Mesenteric Arteriovenous Fistula Following Multiple Gunshot Wounds to the Abdomen

Arteriovenous Fistula of Superior Mesenteric Artery: An Unusual Cause of an Massive Lower Gastrointestinal Bleeding

Introduction

The most common causes of lower gastrointestinal (GI) hemorrhage are diverticulosis and angiodysplasia. Arteriovenous fistula (AVF) of the intestine is an uncommon cause of GI hemorrhage.

Case Presentation

Herein, we report a case of an embolization of an AVF originated from the superior mesenteric artery and vein as a cause of acute massive lower GI bleeding.

Conclusion

The patient underwent a right hemicolectomy and ileotransversostomy.

Endovascular Treatment of Post-traumatic Superior Mesenteric Arteriovenous Fistula: A Case Report

Superior mesenteric arteriovenous fistulae (SMAVFs) are extremely rare with no consensus about therapeutic indications and optimal approach. Here, we present a case of a symptomatic SMAVF found in a young patient a few years after a penetrating abdominal injury. Following a complex clinical management of the acute status, we successfully managed the fistula with 3 covered stents in 2 consecutive endovascular procedures. Technical details of the performed procedures, including the main pitfalls and chosen solutions, have been explored and discussed.

Superior mesenteric arteriovenous fistula embolisation complicated by bowel ischaemia

Superior mesenteric arteriovenous fistulas are rare, especially when iatrogenic in origin. Management of these fistulas can be surgical or endovascular. Endovascular embolisation is the preferred modality with a low rate of complications. Among the reported complications, bowel ischaemia is considered an unlikely occurrence. We report a case of a complex iatrogenic arterioportal fistula that was managed by endovascular embolisation and controlled through both its inflow and outflow, and was later complicated by bowel ischaemia.

Superior mesenteric arteriovenous fistula: imaging findings and endovascular treatment

Arteriovenous fistulae (AVF) of the superior mesenteric vasculature are rarely encountered. We present a case of an iatrogenic superior mesenteric AVF following subtotal colectomy, which was successfully treated with coil embolization. Cross-sectional imaging and angiographic findings are reviewed along with the options for endovascular therapy.
