Harvesting of the radial artery: subfasciotomy or full skeletonization: a comparative study.
BACKGROUND
Long fasciotomy of the posterior aspect of the radial artery (RA) for the purpose of sympathectomy is one of the surgical techniques for the preparation of this graft. We compared the early results of this technique with those of the RA graft harvested as a pedicle in the conventional fashion.


METHODS
The study patients have been selected from the patients who underwent coronary artery bypass grafting (CABG) using the RA graft harvested either with a long posterior fasciotomy (group 1) or as a whole with a pedicle in the classical manner (group 2). Only the patients with a flow study have been included. The flow index was described as the bleeding amount of the RA in a minute per body surface area (mL/m2 min). The flow index has been performed before and after fasciotomy in group 1, and after full skeletonization in group 2. The clinical and demographic parameters and flow indices were measured and compared between the groups, and in group 1, before and after fasciotomy.


RESULTS
From 218 patients with CABG using the RA between January 1998 and August 2005, a total of 57 patients were recruited into the study. Group 1 consisted of 25 patients. Thirty-two patients constituted group 2. Subfascial dissection of the RA increased the blood flow index from 48 +/- 20 mL/m2 min to 51 +/- 19 mL/m2 min (p < 0.001). The comparison of the clinical, perioperative characteristics of the patients was not different between the groups.


CONCLUSIONS
The necessity of total skeletonization of the RA should not be the only option when the aim is to reduce the spasm. While subfascial dissection (sympathectomy) of the pediculed RA alone provides a satisfactory increase in the blood flow index, it also reduces the manipulation time as well as the risk of injury to the graft.
