Mutual interference is a key obstacle in the realistic adoption of full-duplex (FD) technique in future wireless cellular networks. Interference is a much more pressing problem for FD system than for the conventional half-duplex (HD) system, because FD allows the same time-frequency resource to be used for both uplink and downlink, thus possibly creating myriad interference between multiple tra...

OBJECTIVE The aim of this study was to investigate a possible overestimation of the degree of contralateral carotid artery stenosis by duplex in patients with significant bilateral carotid stenoses who are to undergo carotid endarterectomy (CEA). METHODS A retrospective analysis was performed of all patients undergoing CEA in our center over a period of 11 years. Pre- and postoperative duplex...

We describe a case of 72-year-old patient with recurrent transient ischemic attacks in the right internal carotid artery (ICA) territory associated uncontrolled hypertension. Duplex ultrasonography und angiography showed 60% stenosis signs vulnerable plaque cervical segment, as well 90% cavernous segment ICA. After further examination was diagnosed an 80% renal stenosis. First, had single-stage...

Abstract Aims This systematic review assessed literature concerning preoperative magnetic resonance angiography (MRA), computed tomography (CTA), and duplex ultrasonography to determine the sensitivity specificity at detecting lower limb arterial stenosis and/or occlusion, with digital subtraction (DSA) as reference standard. The aim was see if any, or a combination of, methods could replace DS...

OBJECTIVE To investigate the usefulness of computed tomography venography (CTV) for evaluation of leg swelling, especially deep vein thrombosis (DVT), in rehabilitation patients. METHODS A hundred twenty-three patients, who had performed CTV performed because of suspected DVT in our clinic, were enrolled. We performed chart reviews retrospectively and categorized CTV findings as follows: DVT ...

INTRODUCTION Glomus tumors are rare neoplasms arising from the subcutaneous glomus apparatus. They account for 1 - 5% of the soft tissue tumors of the upper extremity, occurring in most cases in the nail bed. The typical clinical presentation includes paroxysmal pain and hypersensitivity to cold which limit the use of the affected hand causing practical, professional and often emotional discomf...

BACKGROUND AND OBJECTIVES Peripheral arterial disease (PAD) is a known predictor of cardiovascular morbidity and mortality among hemodialysis patients. Although ankle-brachial BP index (ABI) is a simple and reliable test for PAD screening, its sensitivity has been suggested to decrease among dialysis patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We performed a cross-sectional outpat...
