OBJECTIVE The purpose of this study was to determine the cause and frequency of aneurysm rupture after endovascular aneurysm repair. METHODS We reviewed each patient who sustained aneurysm rupture among all patients enrolled for endovascular aortic aneurysm repair in phases I, II, and III of the US AneuRx Multicenter Clinical Trial from June 1996 through October 1999. RESULTS A total of 106...

OBJECTIVE To measure morphological indices and wall shear stress (WSS) of aneurysms and parent artery surface in order to explore the relationship of morphological characteristics and WSS. METHODS Data from 47 events of consecutive cerebral saccular aneurysms from 39 patients which were referred to the interventional Neuroradiology service of the Shaoxing People`s Hospital, Shaoxing, China be...

AIM The brain venous drainage dominance is generally divided into three groups; right or left dominance and co-dominance. There is no study in the literature examining the link between brain venous drainage and aneurysm formation or rupture. Our aim was to evaluate the association between venous dominancy, aneurysm formation and rupture. MATERIAL AND METHODS Eighty-six patients, who underwent...

BACKGROUND If undetected, infrarenal Abdominal Aortic Aneurysm (AAA) growth can lead to rupture, a high-mortality complication. Some AAA patients exhibit inhomogeneous luminal contrast attenuation at first-pass CT angiography (CTA). This study assesses the association between this observation and aneurysm growth. METHODS Sixty-seven consecutive pre-repair AAA CTAs were included in this retros...

Considering the blood coagulation induced by the heating of radio frequency ablation (RFA) and the mechanism of aneurysm embolization, we proposed that RFA may be used to treat arterial aneurysm. But the safety of this method should be investigated. A finite element method (FEM) was used to simulate temperature and pressure distribution in aneurysm with different electrode position, electric fi...

conclusions this rare observation supports the role of immunosuppressive therapy in preventing the recurrence of life-threatening vascular lesions in the management of behcet’s disease. introduction arterial involvement in behcet’s disease has been previously described. we report a rare case of a large and long-segment thoracoabdominal aneurysm, which was associated with behcet’s disease and ha...

osteogenesis imperfecta (oi) as an inherited connective tissue disorder can affect all tissues that contains type i collagen. well-known cardiac complications of this disease such as aortic root dilatation, aortic regurgitation and mitral valve prolapse have been rarely reported in the literature. coronary artery aneurysm is a rare cardiac complication in oi, as reported in a 19 year old female...

PURPOSE To evaluate and compare the deliverability, positioning, stability, and effectiveness of aneurysm occlusion and the incidence of parent-artery thrombosis of two different types of platinum coils, using a canine carotid aneurysm model. METHODS 29 experimental canine carotid aneurysms (19 lateral, 6 bifurcation, and 4 terminal) were constructed and treated with complex-shaped fibered pl...

Recanalization of intracranial aneurysms following endovascular coiling remains a frustratingly common occurrence. An understanding of the molecular and histopathologic mechanisms of aneurysm healing following coil embolization is essential to improving aneurysm occlusion rates. Histopathologic studies in coiled human and experimental aneurysms suggest that during the first month postcoiling, t...

RATIONALE Coarctation of aorta in adulthood is usually complicated by other cardiovascular anomalies, posing great technical challenge for intervention. PATIENT CONCERNS Here, we report an extremely rare case of aortic arch coarctation combined with a poststenotic biloculated calcified aneurysm and hypoplastic left subclavian artery. INTERVENTIONS First, an extra-anatomic bypass was establi...
