BACKGROUND Ankaferd Blood Stopper® (ABS) is a folkloric medicinal plant extract used as a hemostatic agent in traditional Turkish medicine. This experimental study investigated the histopathological and immunohistochemical effects of ABS on vascular tissue in a rat model of aortic bleeding. METHODS Four groups of 11 Wistar albino rats were used. The abdominal aortas of the rats were wounded; ...
Shortly after the Roentgen's discovery (1895), X-rays were applied for depicting vascular system (Lindenthal and Haschek 1896). But it took rather long time before another brilliant idea (Seldinger 1953) for percutaneous puncture and catheterization of superficial artery was developed instead of these previously performed and the surgical arteriotomy. The percutaneous puncture enabled another i...
Risk‐Treatment Paradox in the Selection of Transradial Access for Percutaneous Coronary Intervention
BACKGROUND Access site complications contribute to morbidity and mortality during percutaneous coronary intervention (PCI). Transradial arterial access significantly lowers the risk of access site complications compared to transfemoral arteriotomy. We sought to develop a prediction model for access site complications in patients undergoing PCI with femoral arteriotomy, and assess whether transr...
Percutaneous interventions including balloon angioplasty and stenting have been used to restore blood flow in vessels with occlusive vascular disease. While these therapies lead to the rapid restoration of blood flow, these technologies remain limited by restenosis in the case of bare metal stents and angioplasty, or reduced healing and possibly enhanced risk of thrombosis in the case of drug e...
Carotid endarterectomy is a commonly performed operation to remove plaque at the region of the carotid bifurcation. We present our technique to keep the field clear and to minimize potential trauma to the carotid using a neurosurgical external ventricular drain passed behind the common carotid and placed in the dependent position under the arteriotomy.
Vascular surgery aimed at stenosis removal induces local reactions often leading to restenosis. Although extensive analysis has been focused on pathways activated in injured arteries, little attention has been devoted to associated systemic vascular reactions. The aim of the present study was to analyse changes occurring in contralateral uninjured rat carotid arteries in the acute phase followi...
OBJECTIVES Polyamines are organic polycations playing an essential role in cell proliferation and differentiation, as well as in cell contractility, migration and apoptosis. These processes are known to contribute to restenosis, a pathophysiological process often occurring in patients submitted to revascularization procedures. We aimed to test the effect of α-difluoromethylornithine (DFMO), an ...
Endarterectomy Outcomes To the Editor: In a resent publication by Kapral and colleagues, it was concluded that the perioperative rates from carotid endarterectomy are similar in male and female patients.1 Respectively for male and female patients, the perioperative mortality rates were 1.8% and 1.2%, the nonfatal stroke rates were 4.2% and 5.0%, and combined death or stroke rates were 5.9% and ...
We present a patient with blunt abdominal trauma with severe acute right limb ischemia and clinical signs of diffuse peritonitis. Computed tomography angiography showed circumferential dissection of the infrarenal aorta with occlusion of the right common iliac artery. We opted for simultaneous abdomen exploration and open repair of injured aorta. Critical weakening of the aortic wall with immin...
