Percutaneous brachial approach in left heart catheterization with 5 Frenchcatheters. Preliminary experience

This describes our preliminary experience with percutaneous brachial approach for cardiac catheterization, by using 5 French (F) preformed catheters. Thirty patients (pts) were studied from the left arm (Group A) with a 5F sheath and 5F Judkins catheters and 30 from the right arm (Group B) with 5F sheath and 5F Amplatz catheters. Pigtail catheters (5F) were used for the left ventricular angiograms in all patients. In 10 patients arterial velocity signals and radial and ulnar artery blood pressures were monitored with the Doppler ultrasonic velocity detector before and immediately after each procedure, and 24 hours later. Arterial puncture was carried out successfully in each patient by using a 18-gauge Potts-Cournand needle. The puncture site was as close as possible to the ante cubital fossa where the artery is less mobile. Both coronary arteries were selectively opacified and the left ventricular angiography was done on every patient. The diagnostic quality of the angiograms was evaluated by the visual analogue scale and the results were not different from those obtained with the femoral approach in our catheterization laboratory. In 3 out of 30 pts in group B it was impossible to obtain a good left coronary opacification with Amplatz catheters for anatomical reasons, thus the right femoral approach was preferred. Brachial artery occlusion occurred in 1 patient from group B and needed surgical thrombectomy carried out to restore normal radial and ulnar pulses.(ABSTRACT TRUNCATED AT 250 WORDS)
