Endovascular treatment for para-anastomotic abdominal aortic and iliac aneurysms following aortic surgery
No full textAIM:
The aim of this study was to report our experience with endovascular repair of anastomotic aneurysms occurring after graft replacement for abdominal aortic aneurysms or aorto-iliac obstructive disease.
METHODS:
Between January 2000 and April 2006, 19 consecutive male patients (median age 73 years) underwent endovascular repair for 22 anastomotic aneurysms [proximal aortic (n=15), iliac (n=4), concomitant aortic and iliac (n=3)], occurring 3 months to 18 years (mean 8.6 years) after open surgery. Three patients (15.7%) underwent emergency treatment for rupture. No patient had symptoms or positive blood tests for infection of the original graft. Twelve patients were treated with a bifurcated stent-graft, 4 patients with a proximal stent-graft cuff, 2 patients with a tube iliac stent-graft, and 1 patient with a mono-iliac stent-graft.
RESULTS:
Stent-grafts were successfully deployed in all patients. Procedure-related complications or death were not observed; open conversion was never required. Median hospitalisation was 9 days (range 3-45). During a median follow-up of 16 Euro-months (range, 2-44) all anastomotic aneurysms maintained excluded: 4 patients (21%) died. We observed 1 major complication (5.2%): an iliac branch occlusion occurred 1 month after the procedure, successfully treated with catheter-directed thrombolysis. Overall, survival rates at 6, 12, 18 and 36-months were 92.8%, 84.4%, 72.3%, and 57.8% respectively.
CONCLUSION:
Our experience confirms that endovascular stent-grafts can be used successfully to exclude anastomotic aortic aneurysms after open surgery. Endovascular repair seems to be effective at mid-term follow-up
Splenic artery aneurysms: post-embolization syndrome and surgical complications
No full textBackground
This study assessed the endovascular embolization of splenic artery aneurysms and false aneurysms with special consideration given to postoperative complications.
Methods
Fifteen patients (11 women; mean age, 56 y; range, 39–80 y) with splenic artery aneurysm (n = 13) or false aneurysm (n = 2) were treated with coil embolization. The lesion was asymptomatic in 9 patients, symptomatic in 5 patients, and ruptured in 1 patient. The mean aneurysm diameter was 33 ± 23 mm (range, 15–80 mm). Postoperative follow-up evaluation included a clinical visit and spiral computed tomography at 1, 4, and 12 months, and yearly thereafter.
Results
Endovascular treatment was possible in 14 patients (93%) (1 failure: neck cannulation). Perioperative mortality was not observed. Morbidity included postembolization syndrome in 5 patients (30%). Neither pancreatitis nor spleen abscess occurred. The mean follow-up period was 36 months (range, 3–60 mo). During follow-up evaluation we detected 1 sac reperfusion that was sealed successfully with additional coils. Surgical conversion or open repair were never required.
Conclusions
At our institute, endovascular treatment represents the first-line treatment for splenic artery aneurysms. Postembolization syndrome and infarcts are common events but generally resolve without sequelae
