PURPOSE To evaluate an embolic agent that is precisely calibrated, perfectly spherical in shape, and soft but nonresorbable for use in the embolization of vascular disease of the head, neck, and spine in humans. METHODS We used supple, hydrophilic, and calibrated trisacryl gelatin microspheres 200, 400, 600, 800 and 1000 microns in diameter for superselective embolization in 105 patients (27 ...

Superior mesenteric artery aneurysms are rare and associated with high mortality rates in cases of rupture. Current Society for Vascular Surgery guidelines recommend treatment all superior regardless size. A 53-year-old woman who was admitted abdominal pain found a 14-cm, ruptured branch aneurysm. Endovascular approach performed microvascular plug embolization feeding aneurysm sac exclusion ste...

Abstract The renal arteries arise from the lateral side of abdominal aorta at L2 vertebral level, just below origin superior mesenteric artery. Multiple aberrant can pose difficulties in transplantation, interventional radiological and urological procedures, artery embolization, angioplasty, or vascular reconstruction for congenital acquired lesions. We present a case left kidney supplied by al...

BACKGROUND Follow-up imaging after coil embolization of visceral artery aneurysms is important for detecting recanalization. However, CT examination is susceptible to coil artifacts, which sometimes makes it difficult to assess recanalization. We report 2 cases where recanalization was successfully visualized using time-resolved magnetic resonance angiography after coil embolization of visceral...

Schwannomas are tumors derived from nerve sheath cells, which are often located in the head and neck, including the CNS. Although a definitive vascular pattern has been previously characterized for these lesions, preoperative embolization of the more vascular schwannomas has not been described. In a review of eight patients with schwannomas who underwent angiography at our institution since 198...

Abstract Background Delayed post-traumatic bleeding at various sites is known due to vascular abnormalities related structural changes in the vessel walls, form of pseudo aneurysms and arteriovenous malformations. epistaxis following facial trauma a distinct entity that presents as recurrent episodes from nose. History important differentiate it idiopathic intractable epistaxis, management whic...

a 15- year-old boy with history of bb gun injury to his left eye was referred to our center. his visual acuity was no light perception in the left eye. ocular findings were severe proptosis, conjunctival injection, and conjunctival vascular tortuosity. fundus examination revealed an extensive inferior chorioretinal scar compatible with chorioretinitis sclopetaria. a distinct bruit was detected ...

of toes), strongly suggests this disease. Biopsy of the skin or the kidney demonstrates cholesterol crystals, biconvex, needle-shaped clefts whitin the occluded vessel. These intraluminal lesions are often accompanied by a perivascular inflammatory reaction that may contain eosinophils [2] . The reported incidence of renal atheroembolic disease during the last 10 years seems to have increased b...

Introduction . Intraoperative control of bleeding during surgical treatment juvenile nasopharyngeal angiofibroma (JAN) remains controversial. There is no consensus as to the routine use preoperative embolization, given its high cost and inconsistent availability procedure in care centers. were publications devoted comprehensive pharmacoeconomic analysis vascular embolization (PVE) occlusion cla...

ObjectiveLittle evidence is available supporting the optimal treatment of type II endoleaks associated with aortic sac growth. Previous studies have lacked comparisons between methods and long-term follow-up. The purpose present study was to review our center's experience comparing Onyx (a liquid embolization agent consisting ethylene vinyl alcohol; Medtronic, Minneapolis, Minn) coil embolizati...
