No change in O2 saturation but measurable difference in thenar flexor power after radial artery harvest

Abstract

Our findings confirm the hypothesis that there are objective differences in TFP pre and post RA harvest at 3 months. Further studies are required to assess the clinical significance and persistence of the loss of TFP.

Effect of Low Dose Electrocautery Usage during Radial Artery Harvesting on the Neurological Outcome of the Forearm: A Neuroelectrophysiological Study

“…Thus, the proposal that this complication was the result of thermal injury caused by electrocautery was discarded as a possible reason. Motor disorders have also been reported in the literature [9,12]. Denton et al reported the incidence of thumb weakness to be 5.5% [9].…”

Retrospective Analysis of Local Sensorimotor Deficits After Radial Artery Harvesting for Coronary Artery Bypass Grafting

“…The purpose of this study was to describe the technique for RA harvest and evaluate the upper limb sensory and motor morbidities occurring in the long-term period after RA harvesting. While studies have examined objective neurological signs of impairment [9], our study examines the patient's perception. In addition, we evaluated preoperative patient characteristics to determine risk factors for developing complications with RA harvest.…”

Consequences of Radial Artery Harvest

“…Based on a review of previously published information, [2][3][4][5][6][7][8][9][10][11][12][13][14][15] the hypothesis tested in this study is that sensory and motor dysfunction associated with procurement of the radial artery largely resolves within a year of surgery and is not substantially worse than the discomfort associated with procurement of the saphenous vein. To our knowledge, no trial to date includes all attributes of CSP 474 (ie, a multicenter prospective randomized trial with quantitative assessments of pain and motor function by trained personnel that use widely accepted measurement tools at specified times before and after surgery) (details of prior literature in Table 1).…”
