In order to find out the causes, diagnosis, and the prevention and treatment of vascular crisis following anastomosis of small vessels, 314 cases vascular crisis from 1985 to 1997, were analyzed, in which 152 cases, suffered from tissue necrosis either total or partial, making up 48.4%. One hundred and forty-four cases underwent conservative treatment occupying 45.8% and 104 cases had tissue necrosis, occupying 68.4%. Operative exploration was done on 170 cases, occupying 54.1% and 48 cases of them suffered from necrosis, which made up 31.6% of all necrotic cases. Eighty-six cases were followed up by regular visits, ranging from 40 days to 7 years, with the finding that those who had regained normal circulation after vascular crisis recovered as well as those without crisis, and among those who did not regain normal circulation but survived with the help of collateral circulation after vascular crisis, they were usually cases of bad union, healing of wound, persistent swelling, different degree of tissue atrophy, poor recovery of sensation. It was concluded that proper use of vascular anastomosis technique and prophylactic measures preventing postoperative vascular spasm were extremely important, in the prevention of development of vascular crisis following anastomosis of small vessels. If vascular crisis did not respond well to conservative treatment, prompt surgical exploration should be undertaken.
OBJECTIVE: To investigate the clinical effects of the microsurgical treatment for the skin-degloving injury of the whole hand or foot. METHODS: From March 1984 to October 2001, we treated 6 cases of skin-degloving injury of the whole hand and foot. In 2 cases of skin-degloving hands, one was treated with free great omentum transplantation plus skin graft, the other with pedical abdominal S-shaped skin flap as well as mid-thick skin graft. In 4 cases of skin-degloving injury of the foot, 2 cases was repaired with free latissimus dosi musculocutaneous flap, 1 case with distall-based lateral skin flap of the leg and 1 case with free tensor fasciae latae muscle flap. The flap size ranged from 7 cm x 9 cm to 22 cm x 15 cm. One case was operated on the emergency stage, the other 5 cases on the delayed stage. The delayed time ranged from 2 to 14 days with an average of 6.6 days. RESULTS: All the flaps survived. After 1-2 year follow-up, the appearance and function of the hand and the foot were good. CONCLUSION: Microsurgery technique in repairing skin-degloving injury of the whole hand and foot can achieve good results. The keys to success are thorough debridement of the recipient area, appropriate selection of the donor site, good vascular anastomosis and active postoperative rehabilitation.
Since Ⅰ982, Twenty-five cases of birth injuries of brachial plexus have been treated by microsurgical technipue. The satisfactory result has been obtained. The excellent and good rate are 76 per cent. The operative method included endoneurolysis, anastomosis of nerve, supraclavicular nerve grafting and transposition of phrenic nerve, accessory nerve and cervix motor nerve. In this article, the early diagnosis and differentiel diagnosis, practical physical examination method, and operative technipue were descused.

ObjectiveTo investigate the management strategies of clavicular fracture combined with brachial plexus injury and its effectiveness. MethodsBetween January 2006 and January 2012, 27 cases of clavicular fracture combined with brachial plexus injury were treated. There were 18 males and 9 females, aged 18-42 years (mean, 25.3 years). The causes of injury were traffic accident in 12 cases, falling from height in 10 cases, bruise in 3 cases, machinery injury in 2 cases. According to the Robinson classification, the clavicular fractures were rated as type Ⅰ in 2 cases, as typeⅡin 20 cases, and as type Ⅲ in 5 cases; there were 12 cases of total brachial plexus root avulsion injury, 10 cases of bundle branch injury, and 5 cases of hematoma formation and local nerve compression or injury. The injury to operation time was 6 hours to 14 days (mean, 4 days). Brachial plexus injury was repaired by epineurium neurolysis, nerve anastomosis, or nerve transposition after the exploration of the plexus; and fracture was fixed after open reduction. Sensory grading standard (S0-S4) by UK Medical Research Council (MRC) was used to evaluate the recovery of sensory function, and muscle strength grading standard (M0-M5) by MRC to evaluate the innervating muscle strength. ResultsThe incisions healed by first intention. All patients were followed up 18-36 months (mean, 26.3 months). All fracture achieved cl inical healing at 12-17 weeks (mean, 15 weeks). No complication of loosening or breakage of internal fixation occurred. The patients had no pain of shoulder in abduction. At 18 months after operation, the shoulder abduction was more than or equal to 60° in 8 cases, 30-60° in 8 cases, and less than 30° in 11 cases. The recovery of biceps muscle strength was more than or equal to M3 in 18 cases and less than M3 in 9 cases; the recovery of wrist flexion or flexor muscle strength was more than or equal to M3 in 13 cases and less than M3 in 14 cases. The sensory function recovery of median nerve was S3 in 14 cases, S1-S2 in 9 cases, and S0 in 4 cases. The shoulder abduction, elbow and wrist flexor motor function did not recover in 2 patients with total brachial plexus root avulsion injury. ConclusionIt is beneficial to the recovery of nerve function to early repair of the brachial plexus injury by exploration of the plexus combined with open reduction and fixation of clavicular fractures, the short-term effectiveness is good.
