OBJECTIVE To evaluate radial and ulnar artery diameter in patients undergoing diagnostic coronary angiography. METHOD This was a cross-sectional study in which we measured the inner diameter of radial and ulnar artery by using two dimensional ultrasound and Doppler examination in 251 patients visiting our hospital for diagnostic coronary angiography between February to September 2008. RESUL...

We report a new technique for treatment of radial artery pseudoaneurysm (RAP) caused by transradial access (TRA) for coronary angiography. Traditional extrinsic compression with radial flow cessation leads to a local milieu likely associated with an increase in probability of radial artery occlusion (RAO). Our technique involves obtaining ipsilateral radial artery access distal to the neck of t...

OBJECTIVE Transradial access is widely used for both diagnostic and interventional cardiac procedures. The use of transradial access offers several advantages, including decreased bleeding, fewer vascular complications, and reduced length of hospital stay and cost. However, the small size of the radial artery limits the size of the equipment that can be used via this approach. In this study we ...

Background Few reports describe the distribution of cutaneous perforators from the radial and ulnar arteries in the forearm. This study aimed to map the location of the cutaneous perforators that arise directly from the radial and ulnar arteries in cadavers. Methods Twenty-nine human cadaveric forearms were dissected. All radial and ulnar arteries cutaneous perforators were analyzed for total...

BACKGROUND The superior long-term patency of internal mammary artery coronary bypass grafts compared with venous grafts has been attributed in part to increased endothelium-derived nitric oxide (. NO) production. Interest in the radial artery as an alternative bypass conduit has recently been revived; however, its biological characteristics remain incompletely defined. The purpose of this study...

Development and adoption of endoscopic minimally invasive saphenous vein harvesting prompted its application to the radial artery in an effort to minimize surgical trauma. Recently, we reported that endoscopic radial artery harvesting was associated with better wound appearance and it proved to be safe and effective, with less pain and fewer wound complications than the open surgical technique....

We report a case of an 18-year old female patient with symptomatic extralobar pulmonary sequestration. The initial symptom was sudden-onset right lateral abdominal pain. Enhanced computed tomography showed a 5 cm in diameter, spindle-shaped mass located in the costophrenic sinus with no aberrant artery. Exploratory thoracoscopy showed a haemorrhagic mass caused by strangulation of an aberrant v...

A 46-year-old Vietnamese woman received embolization therapy in order to control postpartum hemorrhage. Angiography revealed an aberrant ovarian artery arising from the right common iliac artery. Superselective catheterization and subsequent embolization of the aberrant ovarian artery and bilateral uterine arteries were performed. Precise knowledge of the anatomic variations of the ovarian arte...

A 79-year-old man with unstable angina developed localized left atrial tamponade after conventional coronary artery bypass grafting (CABG) with endoscopic radial artery harvesting (ERAH). Hemodynamic instability developed several hours after the systemic heparinization. Transthoracic and later intraoperative transesophageal echocardiography revealed a large, isolated hematoma compressing the le...

BACKGROUND Radial artery wall might be damaged after cannulation for cardiac catheterization. We investigated structural changes of the radial artery wall after catheterization to understand whether these might predict radial pulsation loss or occlusion and local pain or functional impairment of the upper extremity. METHODS AND RESULTS Ninety patients underwent transradial coronary angiograph...
