Post radial artery harvest hand perception: postoperative 12-month follow-up results

Patient-reported outcome measures for patients with hand-specific impairments-A scoping review

BACKGROUND

Patient-reported outcome measures (PROMs) are increasingly used to provide evidence for treatment effects and to guide rehabilitation. To our knowledge, no disease-specific PROM exists for the assessment of patients with flexor tendon lesions of the hand. We believe that PROMs used to assess hand function, regardless of diagnosis, contain relevant items for patients with flexor tendon lesions of the hand.

PURPOSE

The aim of our study was to identify and collect items from pre-existing PROMs used by clinical experts to assess the health status and function in patients with reduced hand function.

STUDY DESIGN

A scoping review searching for PROMs with hand-specific content was conducted to ensure face validity. As these items are assumed to have been through an evaluation process by the clinical specialists, they have the advantage and likelihood of being useful.

METHODS

We searched five bibliographic databases. All PROMs with hand-specific content used to assess hand function were considered for inclusion. Questionnaires written in English, Danish, Swedish, and Norwegian were included. An analysis of content redundancy was conducted, and items were grouped according to The World Health Organization's International Classification of Functioning, Disability and Health.

RESULTS

Seventy-three PROMs were included with a total of 1,582 items. The majority of the items were redundant across measurement instruments, and redundant items were consolidated, resulting in 179 nonredundant items. All nonredundant items were classified according to the International Classification of Functioning, Disability and Health components.

CONCLUSIONS

This review presents a collection of 179 items ensuring face validity for patients with hand-related disease/injury.

Radial artery as graft for coronary artery bypass surgery: Advantages and disadvantages for its usage focused on structural and biological characteristics

Radial artery (RA) is the most popular arterial graft after the left internal thoracic artery in both low- and high-risk patients undergoing coronary artery bypass grafting. Various arterial grafts such as the right internal thoracic artery, the right gastroepiploic artery, and the inferior epigastric artery have also gained ground over the past 30 years because of the intimal hyperplasia and atherosclerosis of the saphenous vein leading to late graft occlusion. In this review article we would like to present the utility of the RA as a graft, focused mainly on its structural and biological characteristics.

Revascularization using satellite vein after radial artery harvested for coronary artery bypass grafting

The radial artery has been increasingly used for coronary artery bypass grafting and has excellent long-term patency rates. Hand claudication is one of the adverse effects after radial artery harvest. We reconstructed a radial artery using the satellite vein to prevent hand claudication. Pulsating blood flow at 35 cm/sec was evaluated using color Doppler echocardiography three months after surgery. This method makes it possible to use a radial artery in patients with a positive Allen test.

High-resolution 16-MDCT evaluation of radial artery for potential use as coronary artery bypass graft: a feasibility study

OBJECTIVE

The objective of our study was to assess the feasibility of using 16-MDCT angiography for the preoperative assessment of the radial and ulnar arteries and the palmar arches in patients scheduled for radial artery harvesting for coronary artery bypass graft (CABG) surgery.

CONCLUSION

Sixteen-MDCT angiography shows promise for the noninvasive preoperative assessment of the radial artery as a CABG donor site.

Radial Artery Graft for Coronary Artery Bypass Surgery: Biological Characteristics and Clinical Outcome

The radial artery (RA) is gaining popularity as a bypass conduit for coronary artery bypass grafting, and its impact on clinical practice has been extensively explored. In the present article, we provide a review of postoperative hand circulation, vascular biological characteristics of the RA graft, the efficacy of vasodilator therapies, and mid-term clinical results of use of the RA graft. Fundamental studies revealed excellent vascular biological characteristics of the RA graft as a living arterial conduit, making it almost equivalent to the internal thoracic artery (ITA) graft. Clinical studies have yielded encouraging mid-term results. Most studies reported in favor of the RA graft over the saphenous vein graft with regard to patency rate, freedom from cardiac events, and survival. However, superiority of either the RA or right ITA graft has not been conclusively determined. The long-term results of RA grafts remain unknown, but at present, supplementary use of an RA graft with a left ITA graft appears feasible for CABG.

Role of Radial Artery Graft in Coronary Artery Bypass Grafting

The use of the radial artery (RA) as a coronary artery bypass graft has assumed a revival and thus a multitude of issues have arisen surrounding the routine and widespread use of this conduit in myocardial revascularization. There has been no uniformity regarding harvest techniques, assessment of the adequacy of hand collateral circulation, antispasm protocols, selection of target vessels, and the site of proximal anastomosis. It is widely believed and practiced that the RA should be harvested as a pedicle graft and preferably be used to bypass critically stenosed (>70% stenosis) coronary arteries. It is used either as a free graft with proximal anastomosis to the ascending aorta or as a composite arterial graft along with the left or right internal thoracic artery. The patency of RA grafts depends on the severity of the target coronary artery stenosis and target artery location rather than its use as an aortocoronary conduit or composite graft. In this article, we reviewed the current knowledge regarding the use of RA grafts as a coronary bypass conduit in an attempt to suggest a few acceptable strategies concerning the above issues in a given clinical scenario.

Determining the best procedure for radial artery harvest: prospective randomized trial for early postharvest complications

OBJECTIVE

Although useful procedures for radial artery harvest have been reported, forearm circulation and collateral perfusion after radial artery harvesting remain unknown. To assess an optimal radial artery harvest technique for forearm circulation, we designed a prospective randomized trial.

METHODS

Ninety patients were divided into 3 groups of 30 patients. Electrocautery, an ultrasonic scalpel, or sharp scissors and hemoclips were used to harvest radial arteries in groups 1, 2, and 3, respectively. The incidences of harvest site pain, numbness, swelling, discomfort, hematoma, and infection were compared. With forearm thermography, recovery times from cooled down 5 degrees back to rest temperature were compared between groups. All patients had postoperative forearm angiography at 1 and 12 months.

RESULTS

Although there were no differences in the incidences of pain, swelling, and discomfort, the incidence of numbness was significantly lower in group 3 (P = .003). The temperature recovery time was significantly shorter in group 3 (P = .0009). On postoperative angiography at 1 month, the incidence of the development of interosseous arteries was significantly higher in group 3 (86.7%) than in groups 1 (23.3%) and 2 (36.7%). The 12-month study, however, showed that there was no difference among groups (73.3%, 80.0%, and 93.3% in groups 1, 2, and 3, respectively).

CONCLUSIONS

These results suggest that sharp dissection with scissors and clips may be better for early postharvest forearm circulation and can decrease the incidence of hand numbness. However, there were no differences among the 3 methods with respect to forearm circulation 12 months after radial artery harvest.

Long-term neurologic hand complications after radial artery harvesting using conventional cold and harmonic scalpel techniques

BACKGROUND

The purpose of this study was to determine the incidence of neurologic hand complications after radial artery harvesting and to compare the harmonic scalpel versus conventional cold scalpel technique.

METHODS

From 1995 to 2000, 786 radial arteries were harvested from 782 patients for coronary artery bypass grafting. From 1995 to 1997, the conventional cold scalpel technique was used (422 patients), and from 1998 to 2000, the harmonic scalpel was used (360 patients). Mean follow-up was 4.2 +/- 2.1 years and was 90% complete. Symptoms included thumb weakness or numbness, tingling, or pain in the hand.

RESULTS

The incidence of neurologic hand complications was similar with both techniques (11.2% +/- 3.5% cold, 11.0% +/- 3.6% harmonic, p > 0.95), and in 19% (13 of 67 with symptoms) there was complete resolution within 1 year. Symptoms persisted long-term in 9.0% +/- 3.2% cold scalpel and 9.0% +/- 3.3% harmonic scalpel patients (p > 0.81), but were considered a "constant and significant source of discomfort" in only 0.6% +/- 0.9% cold scalpel and 1.4% +/- 1.3% harmonic scalpel patients (p > 0.41).

CONCLUSIONS

The incidence of adverse neurologic outcomes causing significant long-term discomfort in the hand was low using either the cold scalpel or harmonic scalpel technique. However, a significant number of patients had neurologic hand symptoms in both groups, and this should be included when discussing operative risks with the patient.

Outcome assessment of hand function after radial artery harvesting for coronary artery bypass

The radial artery has gained widespread acceptance as a conduit for coronary artery bypass. Advantages include minimal donor site discomfort, ease of handling, excellent early patency rates, and the possibility of freedom from late conduit atherosclerosis. Although most series describe minimal morbidity, a significant incidence of radial sensory neuropathy and isolated instances of hand claudication and ischemia have been reported. We performed an outcome study utilizing the Short Form-36, the Upper Limb-Disabilities of Arm, Shoulder and Hand, and a modified self-administered hand diagram to compare 288 patients undergoing coronary artery bypass utilizing the radial artery with a control group of 174 patients undergoing coronary artery bypass without the radial artery. The data were analyzed by the t test for continuous variables and the chi-square test for categorical variables, and subsequently a multivariate regression model was constructed. No patients developed hand claudication or ischemia. Although there was an incidence of radial sensory neuropathy of 9.9% associated with radial artery harvest, it was not significantly higher than the incidence in the control group (5.2%, p =.16). Intrinsic patient factors such as obesity, age, diabetes, and peripheral vascular disease were the principal determinants of overall health and quality of life issues.
