conclusion in cases with critical atherosclerotic disease of anterior tibial artery, pta-based biphasic or triphasic retrograde collateral flow prevents ischemia, whereas monophasic support or no retrograde flow remains incapable. results in the patient group, 31 lower limb arteries, of total of 17 cases, were included. after compression maneuver, dpa in 11 cases (six right, five left) showed r...

Case Report A 64-year-old man was admitted to our institution on November 7, 2011, complaining of chest pain upon exertion for the previous year. Prior history: hypertension for more than 10 years, highest blood pressure 215/115 mmHg, 30-year history of smoking, 10 cigarettes per day. ECG on admission showed: increased II, III, AVF leads, small electrocardiogram (EKG)’s Q waves (Q), EKG’s ST se...

BACKGROUND With the expanded use of the radial artery as a bypass conduit in patients undergoing coronary artery bypass grafting, an endoscopic radial artery harvesting method was used to improve esthetics and patient acceptance, and possibly, to decrease hand neurologic complications. METHODS After informed consent and confirmation of adequate ulnar collateral blood flow, 300 consecutive pat...

OBJECTIVE Radial artery (RA) is now used widely as a conduit of choice in coronary artery bypass grafting. Although RA removal is considered safe in the presence of adequate collateral arterial supply, there is still a considerable suspicion on the functional status of the forearm and hand. However, a neurological dysfunction may occur owing to either surgical trauma or ischemic neuropathy. Thi...

provided the original work is properly cited. CC Acromegaly is a condition caused by an excessive secretion of growth hormones [1]. Hypertrophy in the face and extremities can cause enlarged lower jaws, macroglossia, and thickened pharyngeal and laryngeal soft tissues [2]. Hypertrophy in the vocal cord can lead to changes in the upper airway, making airway management difficult during trachea in...

this report presents a case of left radial artery pseudoaneurysm developing at the previous site of invasive monitoring. the patient had prosthetic mitral valve replacement one month earlier, and anti-coagulation therapy had started on the first post-operative day. the patient’s radial artery aneurysm with a 4-centimeter diameter was resected and the radial artery was ligated.

Whether axillary artery injuries associated with proximal humeral fractures must be repaired is uncertain. The present study reports three cases treated with various approaches. In case 1, the left humeral surgical neck was broken, the radial pulse disappeared and the arm temperature was significantly reduced. Computerized tomography angiography (CTA) revealed a 3-cm filling deficiency in the a...

BACKGROUND AND PURPOSE This study was undertaken to examine the relationship between collateral flow and outcome after local intraarterial thrombolytic treatment for basilar artery thrombosis. METHODS Twenty-four patients with symptomatic basilar thrombosis were treated with intraarterial urokinase. Angiograms at the time of treatment were analyzed to characterize collateral flow. The number ...

The retrograde approach for percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) has helped to improve the success rate. It is usually performed through collateral connections that originate from the contralateral coronary artery to the occluded one and by using two arterial accesses and two guiding catheters, most commonly from the femoral approach. A first reported case o...
