Surgical Innovation (Impact Factor: 1.46). 05/2012; 20(6). DOI: 10.1177/1553350612438415
Purpose. A novel technique using the reversed iliac leg of a Zenith device has been reported. This study reports a complicated isolated iliac artery aneurysm (IIAA) using this novel technique and reviews the relative literature to discuss current treatment modalities. Case report. A 46-year-old man presented with a mass in the left lower quadrant accompanied by abdominal pain for 60 days. Computer tomography angiography (CTA) revealed a complicated IIAA and a massive retroperitoneal hematoma. Percutaneous puncture and drainage at the hematoma was done. Enterococcus faecium was isolated from the hematoma. The infection was controlled after 2 weeks of drainage and anti-infection treatment. The IIAAs were successfully excluded using the novel technique. The 12-month CTA follow-up was unremarkable. Conclusion. Using inverted Zenith device legs is safe and effective even in complicated IIAAs. Further studies are warranted before it can become a widely acceptable definitive treatment option.

ABSTRACT: We report our experience of endovascular repair of isolated iliac artery aneurysms using commercially available stent grafts (SGs). Twenty-five patients (mean age 71 +/- 7 years) presented with 33 isolated iliac artery aneurysms (common iliac artery n = 29, external iliac artery n = 4). Five patients were symptomatic. Depending on the proximal iliac neck and the presence of unilateral or bilateral iliac artery aneurysms, the patient was treated by tube or bifurcated SG that was delivered percutaneously (n = 14) or through surgical exposure of one femoral artery (n = 12). In our follow-up control protocol, the patients are routinely scheduled after 1, 4, and 12 months and then annually after the intervention. Primary technical success with an instant exclusion of the aneurysm was achieved in all patients. The perioperative (<30 days) mortality rate was 0. Major complications did not occur. Mean hospitalization was 6 +/- 6 days (range 2-28, median 4). Four patients (16%) died during follow-up. At a mean follow-up of 32 months (range 3-72, median 36), we detected three type 1 endoleaks (14.3%) that were managed with additional SG; two stenoses at the distal extremity of the SGs, treated with mechanical thrombectomy; and additional stent. In the remaining patients (n = 17), computed tomography angiography confirmed the patency of the SG and the absence of device complication (e.g., endoleak, migration, breakage); shrinkage of the aneurysm was observed in 11 cases (52.4%). Overall, survival rates at 1, 4, and 5 years were 91.6%, 73.3%, and 58.6%, respectively; event-free rates at 1 and 3 years were 79.4% and 67.4%, respectively. In our experience, SG treatment for isolated iliac artery aneurysm proved to be a feasible and low-risk procedure with acceptable mid-term results. At our institute, it is the primary alternative to conventional surgical repair and is offered as first-line treatment.Annals of Vascular Surgery 07/2006; 20(4):496-501.

ABSTRACT: Iliac artery aneurysms are rare but associated with significant morbidity and mortality when ruptured. This study compares recent open and endovascular repairs of iliac aneurysms at a single institution. Patients were identified and charts reviewed using ICD-9 and CPT codes for iliac artery aneurysm and open or endovascular repair performed between January 2000 and January 2006. Baseline characteristics, procedure-related variables, and follow-up data were retrospectively reviewed. A total of 71 patients were treated with isolated iliac artery aneurysms. There were 19 open and 52 endovascular repairs. Seven presented with acute ruptures and were treated by open (4) or endovascular (3) repair. Preoperative comorbidities were similar between the two groups. Major perioperative (30 day) complications included three deaths in the open group from cardiovascular complications, all after ruptured aneurysm repair, and one death in the endovascular group (after rupture; one additional perioperative death occurred after 30 days due to colonic infarction) (P = NS). Postoperative complications were less frequent in the endovascular group, although this did not reach statistical significance. The mortality was 50% in the open group and 33% in the endovascular group for patients presenting with a ruptured aneurysm (P = NS). Transfusion requirement was significantly higher in the open group (47%) than in the endovascular group (6%) (P = .03). The mean follow-up was 20 +/- 5 months in the open group and 17 +/- 2 months in the endovascular group (P = NS). Long-term complications included two limb thromboses following repair with a bifurcated stent graft that were treated with thrombolysis plus stenting or a fem-fem bypass. Three endoleaks were identified on postop CT scans, all of which were successfully managed with endovascular techniques. There were no postoperative ruptures or aneurysm-related death. The mean postoperative length of stay was 5.2 +/- 2.3 days (open) and 1.3 +/- 1.0 days (endovascular) (P = .04). This is the first large, case control study comparing open vs endovascular repair of isolated iliac artery aneurysms. Endovascular repair of iliac artery aneurysms is safe and results in decreased length of stay, lower requirement for perioperative blood transfusion, and similar intermediate term outcomes as open repair.Journal of Vascular Surgery 05/2008; 47(4):708-713.

ABSTRACT: To retrospectively evaluate a 12-year experience with endovascular repair of isolated iliac artery aneurysm (IAA). From August 1997 through July 2009, 91 patients (81 men; mean age 71 years, range 31-90) underwent endovascular treatment for isolated IAA at our department. Of these, 77 patients received stent-grafts either alone or in combination with coils or an Amplatzer vascular plug (n = 2); 1 patient received a Smart stent combined with coils, and 13 patients were treated with coil embolization only. The aneurysms were classified according to location: type I = common iliac artery (CIA), type II = internal iliac artery (IIA), type III = CIA and IIA, and type IV = external iliac artery with/without CIA and/or IIA involvement. Primary technical success was 90.1% for all aneurysm types and 93.6%, 80%, 88.8%, and 93.3% for types I, II, III, and IV, respectively. Secondary technical success was 96.7% for all types and 97.8%, 95%, 100%, and 93.3%, respectively, for each type. Clinical success was 93.4% for all types and 97.8%, 85%, 100%, and 86.7%, respectively, by type. Complications in 18 (19.8%) patients included 7 type I endoleaks, 3 type II endoleaks, 2 enlarged aneurysm sacs (incomplete embolization), 5 cases of buttock claudication, and 2 stent-graft thromboses. Two patients were converted to open surgery; 10 underwent secondary interventions. Mortality rates were 1.1% (n = 1) at 30 death days and 23.1% (n = 21) over a mean follow-up of 45.9 months (no aneurysm-related death). Cumulative overall survival was 97.7% at 1 year and 47.6% at 10 years. Freedom from aneurysm-related complications was 88.6% at 1 year and 83.5% at 5 years. Endovascular repair of isolated IAA is a safe and minimally invasive alternative to surgery. However, it may be associated with several complications and must, therefore, be carefully planned.Journal of Endovascular Therapy 08/2010; 17(4):492-503. DOI:10.1583/10-3047.1 · 3.35 Impact Factor
