Embolization of arterial gastrointestinal hemorrhage with Fuaile medical adhesive

Duodenal angiodysplasia: a case report

Background

Angiodysplasia (AD) is an abnormal, ectatic dilated, tortuous blood vessel that is found in the mucosa and the submucosa of the gastro-intestinal tract (GIT). While colonic angiodysplasia is a recognized finding of the lower intestinal tract in the elderly, small intestinal angiodysplasia is rare. However, it is an important reason of GIT bleeding so its detection and proper management can be a challenge. It should be considered among the differential diagnosis in the scenario of mild or intermittent GIT bleedings of obscure cause.

Case presentation

A 71-year-old woman was presented to our emergency department with hypovolemic shock due to lower GIT bleeding, and she was suffering of melena and severe anemia. The revision of past medical history revealed a history of hypertension, diabetes mellitus, and chronic renal disease. After stabilization, she underwent abdominal computed tomography (CT) which revealed a small abnormal vascular lesion along the anterior and posterior wall of the 2nd part of the duodenum. It appeared as blush of contrast in the arterial phase (representing dilated mucosal capillaries draining into tortuous submucosal vein) suggestive of vascular lesion (duodenal angiodysplasia). The patient was transferred to undergo an angiogram which confirmed the diagnosis of duodenal angiodysplasia. Super selective cannulation of the feeding artery was performed followed by post coiling angiogram which revealed successful embolization. No acute complications were encountered during or immediately after procedure.

Conclusion

AD is a rare but important cause that should be considered in the differential diagnosis of GIT bleeding especially in the older patients. It should be looked for in CT angiography done in such a clinical situation. Superselective coil embolization is a safe and effective technique to manage bowel AD.

Transcatheter Arterial Embolization in Acute Non-Variceal Gastrointestinal Bleedings: A Ten-Year Single-Center Experience in 91 Patients and Review of the Literature

Objective: To report the safety and efficacy of trans-arterial embolization (TAE) for upper gastrointestinal bleeding (UGIB) and lower gastrointestinal bleeding (LGIB) due to different etiologies in 91 patients for ten years. Methods: A retrospective analysis of GIB treated between January 2010 and December 2020 was performed. TAE was performed using different embolic agents (coils, particles, glue, gelatin sponge, and EVOH-based agents). Technical success, secondary technical success, clinical success, and complications were evaluated. Results: Technical success was achieved in 74/91 (81.32%) patients. Seventeen patients (18.68%) required re-intervention. Secondary technical success was achieved in all cases (100.0%). Clinical success was achieved in 81/91 patients (89.01%). No major complications were recorded; overall, minor complications occurred in 20/91 patients. Conclusions: TAE is a technically feasible and safe therapeutic option for patients with GIB from a known or blind anatomic source where endoscopic therapy has failed or is deemed unfeasible.

Superselective Transcatheter Arterial Embolization in the Treatment of Angiodysplasia

Acute nonvariceal upper gastrointestinal hemorrhage is a frequent condition associated with significant morbidity and mortality. Angiodysplasia is a common cause of bleeding in the gastrointestinal tract in the elderly. This case report discusses about a 75-year-old woman clinically stable with melena for 2 years due to arteriovenous fistula of upper mesenteric artery branches without adequate clinical and therapeutic treatment. The goal of this article is to report the safety and efficacy of superselective transcatheter arterial embolization with coils in treating lower gastrointestinal bleeding caused by angiodysplasia that was unresponsive to internal medicine treatment and enteroscopy management.
