Today, the artery of approach lies completely on the operator’s choice. The Right Radial Approach (RRA) has been a favorite for most of the interventional cardiologists due to the convenience in operating from the right side. The Left Radial Approach (LRA) has always been a neglected route. LRA does have many advantages over the right, the vascular anatomy being one of them. The aim of our study was to compare the right radial approach of diagnostic coronary angiography with left radial approach. Method: A total of 70 cases of Coronary Angiography (CAG) with normal Allen test and satisfying the inclusion criteria were prospectively observed and studied after randomly assigning them into two equal groups, LRA (Left Radial Approach) n = 35 and RRA (Right Radial Approach) n = 35. Multipurpose TIG (Tiger) catheter was used in both the approaches to catheterize the right as well as left coronary artery. Results: The access time, catheter manipulation time, procedure time, amount of contrast used, hospital stay, intensity of pain experienced, cost of the procedure and quality of coronary angiogram observed were statistically insignificant while the fluoroscopy time was slightly statistically significant which was independent to catheter manipulation time. Conclusions: The neglected Left Radial Approach to coronary angiography is as efficacious, safe and cost effective with reduction in arterial spasm complications when compared to the Right Radial Approach performed by multipurpose Tiger catheter.展开更多

The transradial approach for percutaneous coronary procedures has the advantage of reduced adverse vascular events. Nevertheless, there are chances of transradial procedure failure due to variation in radial artery anatomy. We report a case of high radial artery origin in a 63 year-old-male patient who was taken up for elective radial percutaneous transluminal coronary angioplasty for in-stent restenosis of proximal left anterior descending artery. Subsequently, there was difficulty in negotiating guide wire and balloons, so imaging of radial artery was carried out which clearly demonstrated a high bifurcating radial origin. This case emphasizes the need for imaging of radial artery to delineate underlying anomalies and identifying patients with unfavorable anatomy when technical difficulties are encountered. Imaging in such a situation helps in planning an appropriate strategy.展开更多

The existence of at least a positive radial solution is established for a class of semilinear elliptic problems involving critical Hardy-Sobolev exponent and Hardy terms. The main tools are variational method, critical point theory and some analysis techniques.展开更多

Iatrogenic radial nerve palsy appears to be common complication in treating these fractures. A case series of 20 fracture shafts of humerus were treated with anteromedial plating through anterolateral approach. There was no radial nerve palsy in any of the cases and all achieved fracture union.展开更多
