Insights
Radial artery grafts show promising short-term results for myocardial revascularization. This study found no operative mortality or graft issues in 10 patients, with all remaining symptom-free during follow-up.
Area of Science:
- Cardiovascular Surgery
- Vascular Grafting
- Myocardial Revascularization
Context:
- Coronary artery disease necessitates effective revascularization strategies.
- Radial artery grafts offer an alternative conduit for myocardial revascularization.
- Assessing the safety and efficacy of radial artery grafts is crucial.
Purpose:
- To evaluate the early outcomes of myocardial revascularization using radial artery grafts.
- To assess the safety and patency of radial artery grafts in the short term.
- To determine the impact of radial artery grafting on patient symptoms and graft function.
Summary:
- Ten patients underwent myocardial revascularization with radial artery grafts between March 1996 and April 1998.
- No operative mortality or perioperative myocardial infarction occurred; no hand ischemia was observed.
- At a mean follow-up of 16.6 months, all patients were alive and symptom-free, with one experiencing angina on stress testing.
Impact:
- Radial artery grafts demonstrate a safe and effective option for myocardial revascularization in the short term.
- Precise graft harvesting and calcium antagonist use appear to prevent vasospasm and early occlusion.
- Further long-term follow-up is warranted to fully assess late graft patency and clinical outcomes.
Abstract:
Between March 1996 and April 1998, 10 patients underwent myocardial revascularization using radial artery grafts. The age ranged between 59-81 (mean 67.7) years. The mean left ventricular ejection fraction was found to be 0.53 (range 0.45-0.62). A mean of 3.2 distal anastomoses per patient were performed. There was no operative mortality and no perioperative myocardial infraction was observed. No ischaemia of the hand was noticed. At a mean follow-up of 16.6 months (range 3-27) all patients are alive and free of symptoms. Only one patient had angina at bicycle ergometer test. The precise and atraumatic harvesting of radial artery and use of calcium antagonists prevent vasospasm and early graft occlusion on the short term. To assess the late results longer follow-up is necessary.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
