BACKGROUND AND PURPOSE: Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength limit of the wall tissue. At present, aneurysmal wall mechanics are poorly understood and thus, risk assessment involving mechanical properties ...

ObjectiveHydrosoft coils were developed to serve as finishing coils to prevent aneurysmal recurrence at the neck. Initial animal studies were encouraging since some studies showed endothelial healing across the neck without recurrence over time. However, theoretical concerns exist regarding the potential threat to parent vessels as the Hydrosoft coils at ...

Non-small-cell lung cancer (NSCLC) invading the aorta is staged as T(4). Only 9% of T(4) tumors are resected; the alternative is chemoradiotherapy, but for peri-aortic NSCLC, radiation damage to the aortic wall can induce fatal rupture. We report the case of a 76 year-old man with a 3-cm left lower ...

Aneurysmal subarachnoid hemorrhage (SAH), in addition to the direct effects of the initial hemorrhage and secondary neurological complications, predisposes to medical complications. The proportion of deaths caused by non-neurological medical complications (cardiac, pulmonary, gastrointestinal, renal, hematological) equals that from neurological complications. In particular, pulmonary complications are responsible for 50% of ...

The case is presented of an unusual complication after aortic valve replacement with a Freedom Solo bioprosthesis. Excision of the aortic valve created a discontinuity of the aortic annulus that was missed intraoperatively and left uncorrected after supra-annular placement of the bioprosthesis; this created a pseudoaneurysm with direct communication to ...

Coarctation of the left pulmonary artery may coexist with tetralogy of Fallot or pulmonary atresia with ventricular septal defect. Various surgical methods, such as autologous pericardial patching and intraoperative pulmonary artery stenting, have been used for solving this condition. We proposed a simple and effective technique for treating patients with ...

An intrinsic limitation of video-assisted thoracic surgery (VATS) resides in the impossibility to palpate the lung to identify embedded nodules. We wanted to investigate the use of intraoperative ultrasonography to detect pulmonary nodules during uniportal VATS. We describe our initial experience with the identification of peripheral pulmonary nodules with an ...

Persistent blood flow in aneurysmal sac after bypass-exclusion is well documented in the literature. Aneurysm enlargement, local compressive symptoms and even sac rupture are commonly described complications. Late secondary infection of popliteal artery aneurysm (PAA) following ligation and venous bypass is exceptional. We report the case of late PAA infection ...

Crossed pulmonary arteries are an uncommon anomaly in which the left pulmonary artery originates superiorly and to the right of the right pulmonary artery, and the two pulmonary arteries cross each other. This anomaly may accompany other cardiac anomalies. We encountered this anomaly during echocardiographic examination of a 21-month-old boy. ...

Atrial fibrillation (AF) is increasing in prevalence. Although experienced centers performing radiofrequency pulmonary vein isolation procedures have reported success rates approaching 72%, in rare instances it is complicated by stenosis of one or more pulmonary veins. In this report we present a case of recurrent pulmonary vein stenosis (PVS) following ...

We present a case of an idiopathic pulmonary artery aneurysm in an asymptomatic patient who was treated for an irrelevant medical condition. Pulmonary artery aneurysms (PAA) are quite rare and can either be congenital or acquired. Congenital aneurysms are usually associated with cardiac malformations leading to pulmonary hypertension. Acquired aneurysms ...

Abstract Ductus arteriosus aneurysm (DAA) is a rare cardiovascular lesion diagnosed within the first two months of life or less frequently in the third trimester by antenatal sonography. The true in utero incidence of DAA is unknown as most affected fetuses are asymptomatic at birth. Potential complications include thromboembolism, rupture ...

INTRODUCTION: A remarkable curing rate has been achieved in the treatment of intracranial intractable aneurysms by using flow-diverting stents (FDS). An appropriate metal coverage (MC) of this device influences the hemodynamics of aneurysm significantly but little to branches in vitro. The MC changes after elongation or compression and the actual ...
