PURPOSE The occurrence of a vascular perforation during an endovascular procedure is an unexpected and feared complication which can be fatal. However, the incidence, risk or the mechanism of vascular perforation which can occur in the endovascular management of aneurysms remains unclear. The purpose of the present study was to evaluate the incidence of vascular perforation during endovascular ...

Aneurysm embolization with coil is now widely used clinically. However, the recurrence of aneurysms after embolization has always plagued neurosurgeons because the endothelial layer of the aneurysm neck loses its integrity after being embolized by coil. Bone marrow-derived endothelial progenitor cells (BM-EPCs) could be incorporated into injured endothelium and differentiate into mature endothe...

1 recommends a 1-time screening for abdominal aortic aneurysm (AAA) by ultra-sonography in men aged 65 to 75 years who have ever smoked, on the basis of trials showing a reduction in death from AAA but not improvement in overall mortality. Mr R was such a patient. A 65-year-old, obese former smoker with a history of myocardial infarction and persistent risk factors (hypertension and hyperlipide...

Pediatric vascular disease is rare, and remains a big challenge to vascular surgeons. In contrast to adults, surgery for pediatric vascular disease is complicated by issues related to small size, future growth, and availability of suitable vascular conduit. During the last 30 years, 131 major vascular operations were performed in a tertiary referral center, Seoul National University Hospital, i...

This work presents new fluid-structure interaction (FSI) models in both 2D and 3D of the effect of using vascular stents as treatment of cerebral berry aneurysms. The stent is positioned inside the cerebral artery covering the neck of the aneurysm. The stent is expected to alter the blood flow into the aneurysm such that the blood coagulates due to low blood velocity, and rupture of the aneurys...

F acial vascular malformations can cause dental emergencies that result in fatal or life-threatening and disfiguring situations. 14 Dentists must be aware of the clinical manifestations of these lesions in order to prevent iatrogenically related accidents and to minimize potential spontaneous crises for the patient. Effective treatment depends on the type and location of vascular lesion. Litera...

Angiotensin II (ANG II) promotes vascular inflammation through nuclear factor-kappaB (NF-kappaB)-mediated induction of pro-inflammatory genes. The role of peroxisome proliferator-activated receptors (PPARs) in modulating vascular inflammation and atherosclerosis in vivo is unclear. The aim of the present study was to examine the effects of ANG II on PPARs and NF-kappaB-dependent pro-inflammator...

INTRODUCTION Both aneurysmal subarachnoid hemorrhage and benign perimesencephalic hemorrhage are well-described causes of spontaneous subarachnoid hemorrhage that arise as a result of different pathologic processes. To the best of the authors' knowledge, there have been no reports of both vascular pathologies occurring in the same individual. CASE PRESENTATION A 51-year-old Caucasian woman wi...

Emphysematous psoas muscle abscess has rarely been described and has not been reported to be associated with ruptured mycotic aneurysm. We report two cases of ruptured mycotic iliac arterial aneurysm complicated by emphysematous abscess of the left psoas muscle. Case 1 occurred in a 70-year-old man and Case 2 in a 63-year-old woman. Both patients presented with fever for several weeks. Clinical...
