Percutaneous entry into the distal radial artery and selective coronarography using a French 5 sheath and preshaded catheters were attempted in 100 patients with a normal Allen test. Cannulation of the radial artery was not possible in ten patients, and selective catheterization of the coronary arteries was unsuccessful in two. Manipulation of catheters presented no problem, and arterial spasm ...

Radial forearm free flaps are commonly used for soft-tissue reconstruction after resection of head and neck cancer. It is perfused by the radial artery, leaving the ulnar artery for perfusion of the hand and digits. The absence of distal ulnar artery and associated superficial palmar arch, however, has not been reported in cadaveric dissection. We report a case of unilateral ulnar artery flow a...

BACKGROUND Myocardial revascularization surgery has used several vessels as coronary grafts including internal mammary and radial arteries which have a better prognosis than saphenous vein. Their long-term patency has been associated with the release of endothelium vasodilator and anti-aggregating products such as prostacyclin. Diabetes induces endothelial dysfunction and a high number of diabe...

The radial access is widely used for cardiac catheterization and angioplasty, with advantages such as decreased risk of bleeding and vascular complications. This case reports on a rare complication during cardiac catheterization by radial access: radial artery endothelial tissue avulsion through the catheter and its embolization to the left anterior descending artery, which was resolved by manu...

A rare case of a snuffbox radial artery pseudoaneurysm treated surgically is presented. Given the broad base, short neck and relatively large size of the pseudoaneurysm sac, compression techniques and intra-sac thrombin injection were deemed inappropriate, as they have been associated with ischemic complications within the sparse literature. Open surgical resection of the pseudoaneurysm with pr...

Percutaneous Coronary Intervention (PCI) for Chronic Total Occlusions (CTOs) necessitates dual arterial access to allow visualisation of the vessel both proximal and distal to the occlusion as well as the course of interventional collaterals. Potential access sites include bilateral femoral, combination of femoral and radial and bilateral radial arteries. Trans-ulnar access has been shown to be...

removal of the radial artery for myocardial revascularization: a Doppler study to prevent ischemic complications to the hand. Assessment of the radial artery and hand circulation by computed tomography angiography: a pilot study. According to your study w1x, one of the contraindications for radial artery harvesting is its small inner proximal and distal diameter, smaller than 2 mm (Tables 2 and...
