Parent artery occlusion is an effective treatment for giant intracranial aneurysms that cannot be clipped directly by surgery in patients who tolerate balloon test occlusion. However, concern remains that impaired hemodynamics after parent artery occlusion may cause delayed ischemic events in the ipsilateral hemisphere. We used computed tomography perfusion studies to evaluate the cerebral hemo...

BACKGROUND The goal when resuscitating trauma patients is to achieve adequate tissue perfusion. One parameter of tissue perfusion is tissue oxygen saturation (StO2), as measured by near infrared spectroscopy. Using a commercially available device, we investigated whether clinically relevant blood loss of 500 ml in healthy volunteers can be detected by changes in StO2 after a standardized ischem...

Vascular injuries after total hip arthroplasty are occasionally reported, but we have found only two cases of major arterial occlusion, and none at all involving the common femoral artery. We report two cases of occlusion of the common femoral artery after Charnley arthroplasties, one of which resulted in a below-knee amputation.

Synthetic vascular grafts are used in a wide range of clinical applications. However, they can become prone to occlusion over time, due the growth smooth muscle cells (VSMCs). This phenomenon is associated with graft failure. Here, we describe novel techniques for packaging and integration miniature sensor VSMC growth. The was based on microfabricated array interdigitated platinum electrodes si...

Septic embolism associated with infective endocarditis (IE) is the occlusion of a blood vessel caused by an infected thrombus traveling through bloodstream resulting in ischemia and/or infarction. can result infarction due to vascular and infection, inflammation possible abscess formation. Systemic embolization generally occurs left-sided IE, causing stroke, blindness or endophthalmitis, spleni...

Severe acute respiratory syndrome coronavirus 2, the causative virus of disease 2019, causes thrombosis via direct effects on vascular endothelial cells. Necrosis extremities due to arterial occlusion has been reported in patients with 2019. Here, we report a case multiple occlusions associated Although extent which severe 2 infection is responsible for development necrosis this patient uncerta...

Background/Aims Hepatic ischemia-reperfusion (I/R) injury is a serious concern during hepatic vascular occlusion. The objectives of this study were to assess effects of three techniques for hepatic vascular occlusion on I/R injury and to explore the underlying mechanisms. Methods Liver cirrhotic rats had undertaken Pringle maneuver (PR), hemihepatic vascular occlusion (HH), or hepatic blood i...

Purpose: To describe angiographic, computed-tomography (CT) and pathologic features of ETHIBLOC_Reloaded as a re-designed zein-based fluid embolic agent. Materials and methods: In eight pigs, both kidneys underwent selective transarterial embolization (with complete embolization as embolization endpoint). Each group consisted of two pigs with four embolized kidneys: I-pure ETHIBLOC_ Reloaded, I...

Transradial access (TRA) offers important advantages over transfemoral approachs, including early patient ambulation, improved comfort, less vascular complications, lower health care costs, and reduced adverse cardiovascular events, mortality. Nevertheless, complications of TRA still exist, radial artery occlusion (RAO) occurred in up to 30% cases, a prospective ultrasound study. Due dual blood...

Sudden occlusion of the left anterior descending branch approximately 2 cm. below the ostium of the left circumflex coronary artery in the dog's heart produces a mortality rate of approximately 50 per cent. In dogs weighing approximately 15 kilos surviving more than 24 hours (average 1 week), an infarction is produced which almost invariably measures 5 x 5 cm. on surface. Following coronary sin...
