Insights
Radial artery use in coronary revascularization showed acceptable early complication rates, similar to traditional methods. This study indicates the radial artery is a viable option for myocardial revascularization, expanding arterial graft choices.
Area of Science:
- Cardiovascular Surgery
- Vascular Grafting
- Myocardial Revascularization
Context:
- Coronary artery bypass grafting (CABG) outcomes depend on graft quality.
- Arterial conduits like the radial artery are increasingly used, challenging saphenous vein grafts.
- The safety and efficacy of radial artery grafts in CABG remain debated.
Purpose:
- To evaluate the incidence of early complications associated with using the radial artery in myocardial revascularization surgery.
- To compare radial artery graft outcomes against established benchmarks in coronary surgery.
Summary:
- A retrospective analysis of 230 patients (2000-2001) using radial artery grafts for coronary revascularization was conducted.
- Early complications included atrial fibrillation (14.3%), bleeding (4.3%), perioperative myocardial infarction (2.2%), and mediastinitis (0.8%).
- Overall postoperative mortality was 1.3%, with no deaths directly attributed to radial artery complications.
Impact:
- Radial artery grafting did not increase morbidity or mortality beyond expected levels for coronary surgery.
- The findings support the radial artery as a safe and effective arterial autograft option.
- This expands the range of available arterial conduits for myocardial revascularization procedures.
Introduction:
Among several other factors, in coronary surgery the results depend on the quality and durability of the grafts. Revascularization employing arterial conduits, namely the radial artery, has been playing a growing role, with the aim of replacing the autologous saphenous vein. The benefits and risks of this strategy is still a matter of controversy. The goal of the present study was the evaluation of the incidence of early complications related to the use of radial artery in the revascularization surgery of the myocardium.
Methods:
A series of consecutive patients who underwent coronary revascularization surgery in the CHVNGaia using radial artery, from January 2000 to December 2001, was retrospectively analyzed. Data were obtained through the revision of the clinical charts and hospital database. The major end-point assessed was the 30-day or intra hospital postoperative death; furthermore, acute myocardial infarction, stroke, renal failure, prolonged ventilation and reoperations for acute graft occlusion, bleeding and mediastistinitis were also evaluated.
Results:
During that period of time, 656 patients underwent coronary revascularization surgery, but the radial artery was used in only 230 (35%). Mean age was 60.2+/- 9.1 years and 42 (18.3%) were female. Two hundred and four patients (88.6%) were operated on under extracorporeal circulation. The average number of grafts was 2.6+/- 0.6 per patient. Mean duration of orotraqueal intubation was 2.4 +/- 6 hours. Thirty patients (14,3 %) developed atrial fibrillation and ten (4.3%) had postoperative bleeding. Perioperative myocardial infarction occurred in five cases (2.2%). Two patients (0.8%) underwent reoperation for mediastinitis and one patient (0.4%) was reoperated on for acute occlusion of the graft. The overall postoperative mortality was 1.3% (3 patients).
Conclusion:
The use of radial artery in coronary revascularization did not caused morbidity and mortality, out of the usual context of coronary surgery. The results of our experience suggest that radial artery can be successfully used in myocardial revascularization surgery, enlarging the possibilities of utilization of arterial autografts.

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.
