PURPOSE: To describe our experiences with the treatment of visceral artery aneurysms (VAA) by transcatheter coil embolization and to propose indications for treating VAA by this method.
METHODS: We treated 22 patients with VAA by coil embolization; 9 had splenic-, 7 renal-, 4 pancreaticoduodenal arcade-, and 2 proper hepatic artery aneurysms. All nine splenic artery aneurysms patients presented with chronic hepatitis-C; four had hepatocellular carcinoma. Of the seven renal artery aneurysms patients, four were hypertensive and three had rheumatoid arthritis. Both pancreaticoduodenal arcade artery aneurysms patients manifested severe stenosis of the celiac axis. Our transcatheter coil embolization procedure includes coil embolization and coil-packing of the aneurysmal sac, preserving the native arterial circulation.
RESULTS: Transcatheter coil embolization with aneurysm packing was technically successful in 16 (72.7%) of the 22 patients and the native arterial circulation was preserved. Postprocedure angiograms confirmed complete disappearance of the VAA. In four of the nine splenic artery aneurysm patients, the native arterial circulation was not preserved. In one renal artery aneurysm patient, stenosis at the aneurysmal neck necessitated placement of a stent before transcatheter coil embolization. Magnetic resonance angiographs obtained during the follow-up period (mean 27 months) demonstrated complete thrombosis of the VAA in all 22 patients. Infarction occurred in one splenic- and two renal artery aneurysms patients; the latter developed flank pain and fever after the procedure.
CONCLUSIONS: Transcatheter coil embolization is an effective alternative treatment for patients with saccular and proximal VAA. In particular, the isolation technique using coil embolization is advantageous in splenic artery aneurysm patients.
