| Abstract: | Sixteen translumlnal coronary angioplasty procedures (TCA), eight right coronary artery (RCA) and eight left anterior descending coronary artery (LAD), by the brachial artery cut-down approach, were attempted with 9/16 (56%) immediate successes and 2/16 (12%) early recurrences. The procedure success rate for RCA obstructive lesions, 6/8 (75%) was greater than for LCA obstructions, 3/8 (38%). In six unsuccessful procedures the balloon catheter could not be advanced into the lesion, and in one unsuccessful procedure dissection of the coronary artery proximal to the lesion occurred. The brachial (Sones) technique for transluminal coronary angioplasty permits the use of softer guiding catheters for selective probing and approach to the coronary lesion but may be more likely to induce coronary spasm. Complete and high-resolution pre TCA anglograms with multiple views to disclose the exact anatomy of the coronary artery and Its lesion Is essential to ensure successful dilatation. |
