Nonoperative management of unruptured visceral artery aneurysms: treatment by transcatheter coil embolization

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.

Visceral artery aneurysms: experience in a tertiary-care center

Visceral artery aneurysms (VAAs) often rupture and cause serious morbidity or death. The purpose of this study was to identify conditions associated with VAA in a series of 30 patients treated at our institution from 1988 through 1998. Demographics, types of aneurysms, associated conditions, diagnoses, treatments, and outcomes were recorded and analyzed. Thirty patients (16 men and 14 women) with VAA were identified. The arteries involved were splenic (eight), renal (ten), hepatic (nine), hypogastric (one), celiac (one), and pancreaticoduodenal (one). Five of eight (63%) splenic artery aneurysms occurred in women; however, gender was not a factor in other aneurysmal groups. Splenic artery aneurysm also was associated with cirrhosis in four of the eight (50%) patients. Five of the nine (56%) hepatic artery aneurysms were associated with cirrhosis; two of these were pseudoaneurysms that occurred after liver transplantation. Five of ten (50%) renal artery aneurysms were associated with juxtarenal abdominal aortic aneurysms. Celiac and pancreaticoduodenal aneurysms were associated with gastrointestinal bleeding. Treatments included surgery (19), embolization (eight), and observation alone (three). These data demonstrate that association with other conditions varies according to subgroups of VAA. Despite advances in diagnosis and therapy the heterogeneity of VAA suggests that management must remain individualized.

Visceral artery aneurysms, an experience on 32 cases in a single center: treatment from surgery to multilayer stent

Between 2000 and 2010, 32 patients (17 males; mean age: 64.7 [range: 18-85] years) with visceral artery aneurysms (VAAs) were treated in our center. The site of aneurysmal disease was: splenic artery (18), hepatic artery (5), superior mesenteric artery (3), pancreaticoduodenal artery (3), celiac axis (2), and gastroduodenal (1). Six patients (18.75%) presented with an aneurysm rupture. Nine cases received an endovascular treatment. Primary technical success was achieved in six patients. Failures included one case of immediate stent occlusion, one stent migration, and one failed attempt of embolization. In 24 cases, the surgical treatment was performed successfully. The total survival rate was 90.6% (in urgency: 75%; in election: 95.8%). A follow-up period of 34.7 months (range: 2-117 months) showed good results. Because of the potential risk of rupture, VAAs should be treated. A new endovascular technology based on a multilayer stent could provide us with a new alternative to VAA treatment, guaranteeing both aneurysmatic sac thrombosis and the correct perfusion of the organs. However, this new technology is not suitable for all aneurysms and requires a specific training and learning curve. In subjects with a low surgical risk, surgery guarantees a definitive and long-lasting repair with a good organ perfusion.     

Endovascular treatment of very small intracranial aneurysms

BACKGROUND: The treatment of very small cerebral aneurysms with maximal diameter less than 3 mm remains a challenge for endovascular and surgical treatment. Endovascular treatment of these lesions may be difficult and associated with high risk of complications because of their small size. Our purpose was to assess the feasibility and results of endovascular treatment of these lesions. METHODS: We conducted a retrospective review of our experience and results of endovascular treatments for a series of 11 consecutive patients with 11 very small aneurysms. Of 11 aneurysms, 10 were acutely ruptured, and 1 was unruptured with a previous subarachnoid hemorrhage from another aneurysm. Aneurysms were located at the internal carotid artery (n = 4), the anterior communicating artery (n = 6), and the vertebral artery (n = 1). Seven patients were treated with coil embolization, and remodeling technique was used in 1 case. Three cases underwent intravascular stent implantation. Coil packing was done after in 2 of 3 aneurysms, and stent implantation alone was used in the remaining aneurysm. RESULTS: Coil embolization and stent deployment were carried out without difficulty in all cases. Coil packing was not available after stent implantation in 1 case for unsuccessful navigation of microcatheter into the aneurysm sac. Immediate angiography demonstrated complete occlusion in 10 cases and nearly complete occlusion in 1 case with stent implantation alone. No stent thrombosis and aneurysmal rupture was encountered during treatment. With the exception of 1 patient (Hunt and Hess grade 4) who died of pneumonia 4 weeks after treatment, no clinical evidence of neurologic deterioration and hemorrhagic complication was seen during the follow-up period in the remaining 10 patients. Follow-up angiography for 3 to 12 months (mean, 5.3 months) was available in 6 (60%) of 10 surviving patients, and no aneurysm recanalization was found. CONCLUSIONS: Endovascular treatment may be a feasible and effective therapeutic alternative for very small aneurysms. The long-term efficacy and durability of endovascular treatment for these lesions remains to be determined in a large series.
