About

The purpose of this study was to assess and compare the feasibility, success and safety of Transradial approach (TRA) verses Transfemoral approach (TFA) for diagnostic and therapeutic coronary angiography and coronary interventions, in terms of procedural time, access time, fluoroscopy time, procedural failure, , length of hospital stay in terms of days in hospital, Complications in terms of thrombophlebitis, hematoma, ecchymosis, infections thrombosis of vessel, MACE, Stroke and others.

Full description

Background: PCI has been done traditionally through transfemoral route. But now transradial and transbrachial routes are also coming up in practice. We compared transradial versus transfemoral routes for ease of operability, time for procedure, complications, and failure rates through a prospective study. Methods: 400 Patients admitted in department of cardiology for percutaneous interventions were enrolled in the study. 200 patients were assigned to each group randomly. A single team did all the procedures. Pre procedure, intra procedure and post procedure data of all the patients was collected, tabulated and analysed properly.

The variables studied include Access time ,Fluoroscopy time and overall procedure time, post procedure complications( ecchymosis ,Thrombophelibites, Hematoma, procedure access bleed), Failure rates,post procedure myocardial infarction, stroke, acute renal failure and infections.

400 participants in 2 patient groups

Transfemoral

Active Comparator group

Description:

in case of transfemoral approach our preference was to use right femoral route. The groin was prepared and draped and the site was punctured for femoral access after anesthetizing the skin with 2-4 ml of 1% lignocaine. Once the femoral puncture was done 6F sheath of Cordis variety was introduced and 6F Judkins, catheter was introduced and it was guided under fluoroscopic guidance through the aortic route.

Treatment:

Procedure: transradial

Procedure: Transfemoral

Transradial

Active Comparator group

Description:

Our preference was to use the right radial and right femoral routes as they are nearest to operator while facing cardiac monitors, in our hospital. For the radial approach, the wrist was sterilized and draped in usual fashion. Hyperextension over an arm board was done and skin over the puncture site was anesthetized with 2 - 3 ml of 1% lignocaine. A small scaled incision was performed 1 cm proximal to styloid process of radius where arterial pulse was best felt. The radial artery was punctured with a 21 G needle and 6 F sheath (Cardis, Terumo) were introduced into the artery, using Seldinger technique. All patients received verapamil (5mg) to reduce radial artery spasm. Heparin (weight adjusted) was used only in PCIs to prevent artery occlusion and not in elective diagnostic coronary studies. Long 0.038 Terumo guide wire was used under fluoroscopic guidance.

Treatment:

Procedure: transradial

Procedure: Transfemoral
