Cervical root nerve transfer from the contralateral side has been used for the treatment of brachial plexus root avulsion in 49 patients. Resection of C7 root from the healthy side has produced no long-term symptoms or signs. Nine patients with ten recipient nerves have been followed up for more than two years and seven have obtained a functional recovery. This operation offers a new approach for the treatment of brachial plexus root avulsion.

Circulatory crisis, attributed to cigarette smoking, in three microvascular cases (two toe transfers, one musculocutaneous flap) is reported. After anticoagulation and antispasm treatment only one transfer survived. Coordinated experimental studies in the rat demonstrated that cigarette smoking delayed anastomotic healing. Five days after anastomoses were performed, endothelial cells completely covered the sutures in the experimental smoking group in only 16-19% of sutures, while the control group had a 75% coverage rate. Mechanisms and characteristics of circulatory crisis caused by cigarette smoking are discussed.
