Emergency gastroduodenal artery embolization by sandwich technique for angiographically obvious and oblivious, endotherapy failed bleeding duodenal ulcers
چکیده انگلیسی

AimTo determine the feasibility, safety, and efficacy of adopting a standardized protocol for emergency transarterial embolization (TAE) of the gastroduodenal artery (GDA) with a uniform sandwich technique in endotherapy-failed bleeding duodenal ulcers (DU).Materials and methodsBetween December 2009 and December 2010, 15 patients with endotherapy-failed bleeding DU were underwent embolization. Irrespective of active extravasation, the segment of the GDA supplying the bleeding DU as indicated by endoscopically placed clips was embolized by a uniform sandwich technique with gelfoam between metallic coils. The clinical profile of the patients, re-bleeding, mortality rates, and response time of the intervention radiology team were recorded. The angioembolizations were reviewed for their technical success, clinical success, and complications. Mean duration of follow-up was 266.5 days.ResultsActive contrast-medium extravasation was seen in three patients (20%). Early re-bleeding was noted in two patients (13.33%). No patient required surgery. There was 100% technical success, while primary and secondary clinical success rates for TAE were 86.6 and 93.3%, respectively. Focal pancreatitis was the single major procedure-related complication. There was no direct bleeding-DU-related death. The response time of the IR service averaged 150 min (range 60–360 min) with mean value of 170 min.ConclusionEmergency embolization of the GDA using the sandwich technique is a safe and highly effective therapeutic option for bleeding DUs refractory to endotherapy. A prompt response from the IR service can be ensured with an institutional protocol in place for such common medical emergencies.
