Résumé
Objective:To investigate the efficacy of transcatheter arterial embolization (TAE) in treating postoperative hemorrhage in the gallbladder-pancreas-duodenum(GPD) region.Methods:The clinical data of 39 patients with postoperative hemorrhage in the GPD region who underwent digital subtraction angiography (DSA) examination in Peking Union Medical College Hospital from July 2018 to August 2022 were analyzed retrospectively, clinical regression was compared between TAE-treated and non-TAE-treated patients, and the concordance between DSA and enhanced CT for bleeding indications was analyzed using the Kappa test.Results:Among 39 patients, DSA examination suggested bleeding in 26 patients (66.7%), which were gastroduodenal artery hemorrhage in 4 cases, common hepatic artery and branches in 6 categories, superior mesenteric artery and branches in 6 cases, pancreaticoduodenal artery and branches in 4 cases, pancreatic aorta in 3 cases, splenic artery in 2 cases, and gastric left artery in 1 case. Positive DSA signs manifested as contrast spillage alone in 18 cases (69.2%), pseudoaneurysm alone in 7 cases (26.9%), and pseudoaneurysm with contrast spillage in 1 case (3.8%). 26 patients underwent TAE with a technical success rate of 96.2% (25/26), a clinical success rate of 88.5% (23/26) and a rebleeding rate of 7.7% (2/26). 13 patients didn't undergo TAE and the rebleeding rate was 30.8%(4/13). 14 patients underwent enhanced CT in the same period of DSA, showed low concordance with DSA in determining the presence or absence of bleeding, with a Kappa value of 0.462.Conclusions:TAE is a safe and effective treatment for postoperative hemorrhage in the GPD region. Patients without TAE treated should be alert for rebleeding. When postoperative hemorrhage is suspected, the consistency between enhanced CT and DSA examination results is limited, and DSA examination should be preferred.
