Elective surgical repair has traditionally been considered to be the treatment of choice for the exclusion of isolated iliac artery aneurysms (IAAs). Recently, endovascular repair has evolved as an alternative to surgical repair, especially in patients at high surgical risk. However, in the absence of sufficient proximal necks, iliac artery aneurysms are not suitable for direct deployment of a tubular-shaped endograft. Here we report two cases of IAAs with short proximal necks that were excluded using an endovascular bifurcated stent-graft. The bifurcated stent-graft was successfully deployed with complete exclusion of the aneurysm. In neither case was there evidence of procedural failures. There were no signs of significant complications. We conclude that endovascular repair of IAAs with short proximal necks is feasible and efficient using an endovascular bifurcated stent-graft.

This report describes the open surgical or endovascular treatment of two patients with bilateral internal iliac artery aneurysms (IIAA). To prevent pelvic ischemia, complete aneurysmal resection and pelvic revascularization with an interposition graft was performed in the open surgical case. Endovascular repair including coil embolization of IIAA and stent-graft placement in the common iliac artery was done successfully in the other case. The contralateral IIAA was left undisturbed and followed for 36 months with no change in size. Prevention of pelvic ischemia is important in the simultaneous treatment of bilateral IIAA.

Common iliac artery aneurysm (CIA) often occurs in conjunction with an abdominal aortic aneurysm (AAA), which extends into one or both CIAs in 20% to 30% of patients. Conventional endovascular treatment includes coil embolization of the internal iliac artery (IIA), followed by extension of the main bifurcated AAA stent-graft into the external iliac artery. However, complications from intentional occlusion of unilateral or bilateral IIAs are frequent and sometimes serious. Several methods try to preserve the unilateral or bilateral IIA. Here we report a case of concomitant bilateral CIA and AAA successfully treated with bilateral branched iliac stent-grafts.

The benefits of the use of temporary clipping for intracerebral aneurysm surgery were proved through many experimental and clinical studies. There are two techniques of temporary clipping which are interrupted and continuous clipping. In the study of cerebral perfusion, interrupted clipping reduced ischemic damage to the brain. However, the comparison of histological changes in the arterial wall between them is not reported yet. Temporary clipping on the iliac artery of 80 rats was performed using Yasargil temporary mini clip. The specimens were divided into two groups; Group I (intermittently repeated clipping for 5 minutes was done 3 times on the same site with resting interval for 5 minutes: total clipping time was 15 minutes) and Group II (continuous clipping for 15 minutes). Under the light microscope, the histological findings were examined in the specimens, which were obtained at each time-interval after clipping (0 hr, 3 hrs, 6 hrs, 12 hrs, 3 days, and 3 months). The histological changes of the arterial wall of rat by two techniques for temporary clipping were observed. Although there is no significant difference between two temporary clippings, there is a trend of milder and more delayed arterial change in intermittently-repeated temporary clipping.

Mycotic aneurysm is a disease requiring immediate treatment because of the high risk of rupture. A difficult surgical approach, especially in the case of occurrence on the iliac artery, involving endovascular embolization and extra-anatomic bypass grafting, is known to be a suitable treatment. We performed extra-anatomic bypass grafting after endovascular embolization successfully in two patients. The postoperative computed tomography of both patients showed complete exclusion of the mycotic aneurysm.

Endovascular repair of abdominal aortic aneurysm is associated with low morbidity and mortality rates when compared to open surgery, and this can be used in patients who are at a high risk for open surgical repair. Also, secondary intervention is an important for achieving intermediate and long term success of endovascular repair of abdominal aortic aneurysm as this can resolve complications. We report here on endovascular stent-graft placement and a secondary interventional procedure in the abdominal aortic aneurysm of a patient who had a previously inserted iliac stent.

Iatrogenic pseudoaneurysms are extremely rare in children. Conventional management of pseudoaneurysms in adults has included surgical repair, ultrasound-guided compression, and more recently, endovascular embolization. However, in infants and children, there is little information regarding the applicability of such treatment modalities, which have been effective in adults, because of its rarity. Here, we present the case of a 6-month-old infant who developed a postprocedural pseudoaneurysm of the external iliac artery, which was successfully treated with ultrasound-guided percutaneous thrombin injection.

The causes of sciatica are variable and include musculoskeletal, dermatologic, infectious, neoplastic, and vascular disorders. In many cases, the symptom is usually caused by degenerative disease in the spine with the compression or irritation of spinal nerve. On the other hands, there are also several announced extra-spinal causes including aneurysm, diabetes, and radiation for sciatica in a low rate. Among the extra-spinal cases, aneurysms arising from iliac vessels are sometimes developing a diagnostic confusion with the spinal causes, and delayed diagnosis can lead to poor prognosis. It is very important to pay attention weather the aneurysmal cause is involved in the symptom of sciatica.

This is to report the technique of reversed iliac leg stent-graft in endovascular treatment for isolated internal iliac artery (IIA) aneurysm, which had significant size discrepancy between the common iliac artery (CIA) and external iliac artery (EIA) in 3 patients from different hospitals. Three patients were a 85- and two 82-year-old men. Treated were right IIA aneurysms, sized 6.5x6.2 cm, 5.0x4.0 cm, and 4.1 cm in longest diameter, respectively. The diameters of the right CIA and right EIA measured 21 mm/11 mm, 15 mm/11 mm, and 20 mm/10 mm, respectively. In all cases, reversed iliac leg stent-grafts were prepared on-site; unsheathed and mounted upside-down manually, and deployed in each right CIA. Post-stent-graft angiograms showed complete exclusion of the aneurysms, except for minimal type 1 endoleak in one case. This technique is a useful treatment option in patients with isolated IIA aneurysm.
