Cardiac catheterization has traditionally been performed via access to the arterial circulation from the femoral artery located in the groin. As an alternative to this approach, the radial artery, located in the arm, is gaining wider use in clinical practice. Multiple studies have demonstrated that cardiac catheterization via the radial approach has a very low complication rate, in the short term. This study is intended to determine if there are any differences in the long term complication rate between radial artery cardiac catheterization as compared with femoral artery cardiac catheterization.

In this study, the investigators will investigate how patients' radial artery diameters change according to sex, age, height, weight and body mass index by measuring radial artery diameter...
Radial artery access is increasingly becoming popular among interventional cardiologists for patients undergoing percutaneous coronary intervention(PCI)/ diagnostic angiography secondary t...
The study will evaluate the feasibility and safety of radial approach in patients undergoing coronary catheterisation without any restrictions based on the results of Allen's test.
Coronary angiography is performed to evaluate for obstructive coronary artery disease. This is commonly performed via the transfemoral or transradial approach with the latter increasing in...
Several approaches have been proposed to reduce the risk of RAO, including anticoagulation, immediate postprocedural sheath removal, and a small sheath/radial artery ratio. Doppler ultraso...
Asymptomatic radial artery occlusion (RAO) is a major limitation of transradial catheterization (TRC). Two radial compression hemostatic devices are compared for their respective effects on RAO.
Distal transradial access in the anatomical snuffbox has advantages over standard access in terms of patient and operator comfort levels and risk of ischemia. Radial artery preservation could be a rel...
Aim of this study was to evaluate the collateral blood flow between more distal branches of the middle cerebral artery (MCA) in the case of peripheral MCA branch occlusion on dynamic 4D angiograms. We...
Background The use of radial-artery grafts for coronary-artery bypass grafting (CABG) may result in better postoperative outcomes than the use of saphenous-vein grafts. However, randomized, controlled...
To analyze the magnitude of blood flow energy and characteristics of frequency domain between pulsatile flow and nonpulsatile flow during cardiopulmonary bypass and physiological flow. From January 2...
The larger of the two terminal branches of the brachial artery, beginning about one centimeter distal to the bend of the elbow. Like the RADIAL ARTERY, its branches may be divided into three groups corresponding to their locations in the forearm, wrist, and hand.
A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.
The continuation of the axillary artery; it branches into the radial and ulnar arteries.
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
The direct continuation of the brachial trunk, originating at the bifurcation of the brachial artery opposite the neck of the radius. Its branches may be divided into three groups corresponding to the three regions in which the vessel is situated, the forearm, wrist, and hand.
