BACKGROUND Aneurysm expansion, and consequent endoleaks, after endovascular aneurysm repair (EVAR) is a major problem. Accurate prediction of aneurysm expansion is demanding for surgeons and remains difficult.Methods and Results:We retrospectively analyzed 157 cases of EVAR for abdominal aortic aneurysm (AAA) using a bifurcated main-body stent-graft. There were 62 cases of aneurysm shrinkage af...

large vessel involvement is one of the hallmarks of behcet’s disease (bd) but its prevalence varies widely due to ethnic variation or environmental factors. the aim of this study is to find the characteristics of vasculo-behcet (vb) in iran. in a cohort of 4769 patients with bd, those with vascular involvement were selected. different manifestations of disease were compared with the remaining g...

isolated bilateral internal iliac artery (iia) aneurysm is a rare and potentially lethal disease. endovascular repair of this disorder is a matter of debate. a symptomatic 68-year-old male presented with severe pelvic pains. computed tomography revealed a leaking 46-mm aneurysm in the right iia, a 27-mm aneurysm in the left iia, and ectatic changes at a diameter of 31 mm in the right common ili...

kawasaki disease (kd) is an acute vasculitis syndrome of unknown etiology. it occurs in infants and young children, affecting mainly small and medium-sized arteries, particularly the coronary arteries. generalized microvasculitis occurs in the first 10 days, and the inflammation persists in the walls of medium and small arteries, especially the coronary arteries, and changes to coronary artery ...

introduction: kawasaki disease is a systemic vasculitis that usually involves children younger than 5 years old. etiology is unknown and since there is no labaratory test to diagnose kawasaki disease, the major diagnosis is based on clinical findings .the objective of this study was to determine incidence, complications, time of treatment and clinical manifestations in children with kawasaki di...

Rapidly developed de novo aneurysm is very rare. We present a rapidly developed and ruptured de novo anterior communicating aneurysm 8 days after the rupture of another aneurysm. This de novo aneurysm was not apparent in the initial 3-dimensional computed tomography and digital subtraction angiography. We reviewed the literature and discussed possible mechanisms for the development of this de n...

Cases of spontaneous regression of cerebral aneurysm remnant after incomplete surgical clipping have been rarely reported. This paper reports the regression of an aneurysm remnant after incomplete surgical clipping during postsurgical follow-up. A 50-year-old male presented with subarachnoid hemorrhage because of rupture of an anterior communicating artery aneurysm. An emergency clipping of the...

Replicas of ruptured posterior communicating and basilar artery aneurysms were created from cadaveric specimens and then were placed in a circuit of pulsating non-Newtonian fluid. Individual fluid slipstreams were opacified with isobaric dyes, and images were recorded on film. The slipstreams entered the distal aneurysm neck with impact against the distal lateral wall of the aneurysm. They then...

Idiopathic pulmonary artery aneurysm is a rare condition. This type of aneurysm can be presented with noncardiac symptoms or even asymptomatic. We report a 73-year-old man with a gigantic idiopathic pulmonary artery aneurysm which was referred to our unit for his kidney problems. During his workup we incidentally found the aneurysm by an abnormal chest-X ray and auscultation. Our further evalua...

We report here troubleshooting of intraoperative premature rupture with large anterior paraclinoid aneurysm, which was successfully clipped. A 61-year-old woman with left nasal hemianopia was referred to our institute. Preoperative three-dimensional computed tomography angiography and a left internal carotid artery angiogram showed a large left anterior clinoid aneurysm adjacent to the anterior...
