Abstract
To evaluate the efficacy of superselective transcatheter arterial embolization (TAE) in the treatment of acute peripancreatic bleeding complications. During a 9-year period, 44 patients with acute bleeding of the peripancreatic arteries underwent TAE in our institution. Thirty-eight patients were treated using microcatheters and 6 patients with a diagnostic catheter. Embolic agents included coils (n=38), polyvinyl alcohol (PVA) particles (n=2), isobutyl cyanoacrylate (n=2), coils plus PVA particles (n=1), and coils plus isobutyl cyanoacrylate (n=1). Outcome measures included technical success, clinical success, and the rate of complications. Identified bleeding sources included gastroduodenal artery (n=14), splenic artery (n=9), pancreaticoduodenal artery (n=6), common hepatic artery (n=5), superior mesenteric artery branches (n=4), proper hepatic artery (n=3), and dorsal/transverse pancreatic artery (n=3). Technical success with effective control of active bleeding was achieved in 41/44 patients (93%). Clinical success attributed to TAE alone was documented in 40/44 patients (91%). The rate of major complications was 2% including death in one patient. Superselective TAE allows effective, minimally invasive control of acute peripancreatic bleeding complications with a low rate of therapeutically relevant complications.
