Clinically, thrombolytic therapy with use of recombinant tissue plasminogen activator (tPA) remains the most effective treatment for acute ischemic stroke. However, the use of tPA is limited by its narrow therapeutic window and by increased risk of hemorrhagic transformation. There is an urgent need to develop suitable stroke models to ...

Intra-arterial therapy (IAT) for acute ischemic stroke treatment is evolving. Whereas the efficacy of recanalization with traditional intra-arterial fibrinolysis is relatively poor, mechanically based recanalization with multimodal approaches, stenting and mechanical embolectomy is more effective. Until recently, this has not resulted in overwhelming clinical benefit and has not always equated ...

We sought to define the crude prevalence rate of the persistent median artery (PMA) (palmar type). Although there is no reported case in the anesthetic literature, a few sporadic case reports and series reported in anatomical and orthopedic journals describe an incidence of between 1.5% and 27.1%. We conducted a ...

Coronary ostial stenosis is usually treated by conventional coronary artery bypass graft surgery. Although patch angioplasty is a widely accepted alternative surgical treatment, it has been reported sporadically. We encountered bilateral ostial stenosis with Takayasu disease. This report describes successful patch angioplasty using glutaraldehyde-treated autologous pericardium of bilateral coronary ostial ...

Coronary atherosclerosis is the pathophysiologic background of coronary artery disease. Vascular calcification is an actively regulated form of calcified tissue metabolism and a common feature of coronary atherosclerotic plaques. Interestingly, systematic research has revealed that vascular mineralization, is also a strong and independent predictor of cardiovascular morbidity and mortality. Recently, ...

Cystic adventitial disease (CAD) is a rare vascular disorder, predominantly seen in young healthy men with minimal cardiovascular risk factors. Cystic adventitial disease can affect both arteries and veins. Patients with arterial CAD present with sudden onset or rapidly progressing claudication symptoms, and those with venous CAD present with limb ...

Transapical aortic valve replacement through an apical aneurysm is traditionally contraindicated because of the risk of severe systemic embolization when thrombi are present. However, a chronic fibrotic aneurysm without apical thrombi carries a low risk of distal embolization and can be safely employed for a transapical transcatheter aortic valve replacement ...

Digital peripheral arterial tonometry (PAT) is an emerging, noninvasive method to assess vascular function. The physiology underlying this phenotype, however, remains unclear. Therefore, we evaluated the relation between digital PAT and established brachial artery ultrasound measures of vascular function under basal conditions and after reactive hyperemia. Using a cross-sectional study ...

The increased fetoplacental vascular resistance due to chronic hypoxia cannot be explained by simple hypoxic vasoconstriction, as it sustains to some degree after recovery in normobaric environment. To verify a hypothesis that fetoplacental arteries undergo remodeling of their walls similar to remodeling of pulmonary arteries in hypoxic pulmonary hypertension, we ...

Background: Transradial coronary catheterization has emerged over the last years as a favorable catheterization practice, based on evidence that it is associated with less vascular complications and shorter hospital stays. However, access site crossover appears to be more frequent when the initial route is the transradial one, one of the ...

Increased arterial stiffness is a marker of vasculopathy in chronic kidney disease (CKD) patients, suggesting a significant cardiovascular damage. Detection of arterial stiffness provides physicians with useful prognostic information independent of traditional cardiovascular (CV) risk factors. In addition, this knowledge may help guide appropriate therapeutic choices and monitor the effectiveness ...

The case of a 77-year-old hypertensive man presenting with hemifacial spasm and glossodynia is reported. Imaging studies revealed gross dolichoectasia of the vertebrobasilar arterial system with pontine compression. It is suggested that the neurologic symptoms most likely resulted from pontine compression, rather than from any compression of the cranial nerves.

Massive haemoptysis is the most dreaded of all respiratory emergencies. Bronchial artery embolisation is known to be a safe and effective procedure in massive haemoptysis. Bronchial artery of anomalous origin presents a diagnostic challenge to interventional radiologists searching for the source of haemorrhage. Here, we report a case of massive ...

Traumatic arterial spasm is a phenomenon that has long been questioned by clinicians. Indeed, some would argue that surgical exploration is mandatory whenever there are signs of distal ischaemia following limb trauma. We present a case of angiographically demonstrated tibial artery spasm following gunshot injury. Exploration was unnecessary and distal ...
