Objective To evaluate the efficacy and feasibility of emergency transcatheter arterial embolization (ETAE) in treating critical massive bleeding due to duodenal bulb ulcer. Methods ETAE was carried out in seven patients with acute massive bleeding due to endoscopically-proved duodenal hulh ulcer,who failed to respond conservative measures and were critically ill clinically. Super-selective catheterization of gastroduodenal artery or right gastroepiploic artery was performed. which was followed by arterial angiography to identify the bleeding site. According to the angiographic findings , ETAE with Gelfoam particles ancl coils was carried out. After the operation medical management was given and endoscopy re-examination was conducted. All the patients were followecl up for 3 ～ 6 months. Results Angiographically, gastroduodenal artery bleeding was detected in all seven patients. ETAE was successfully accomplished in all cases. Complete clinical effectiveness was obtained in six patients while partial effectiveness in one case. No procedure-related complications occurred. Conclusion For critical massive bleeding due to duodenal hulb ulcer ETAE is a highly effective and safe treatment. which can be regarded as an alternative to surgery. It is worth popularizing this technique in clinical practice.
