- Detecção de trombose venosa em retalhos livres por medidas de glicemia capilar(2012) MILLAN, Lincoln Saito; ISHIDA, Luiz Carlos; CHOI, Esther Mihwa Oh; GIACCHETTO JUNIOR, Enio Cesar; WEI, Teng Hsiang; MATTAR JÚNIOR, Rames; FERREIRA, Marcus CastroBACKGROUND: Monitoring of free flaps after surgery is vitally important, especially in the first few hours because the timing of reoperation can determine flap salvage or loss. To date, no study has examined the decision to reoperate on a flap based on the objective measure of glycemia or a comparison between flaps that showed good outcomes and those that showed vascular damage. The objective of this study was to evaluate the validity of blood glucose measurements within the flap as a method for monitoring free flaps and to compare the efficacy of this method with that of clinical assessments. METHODS: The study was prospective, included 16 patients with free flaps, and was conducted from May 2012 to July 2012. A team of professionals not involved in the surgery evaluated capillary glycemia. Flaps were clinically evaluated during the immediate postoperative period, on ICU admission, at every 3 hours, and as needed. RESULTS: Of the 16 patients, 5 (31.3%) had venous thrombosis in the first 24 hours. Statistically significant differences were noted in capillary glycemia in patients with or without venous thrombosis in measurements obtained 6, 9, and 12 hours after surgery (P < 0.05). CONCLUSIONS: The measurement of capillary glycemia was not superior to clinical evaluation by an experienced professional for the detection of venous thrombosis within free flaps.
- LIMB REPLANTATION AFTER AVULSION INJURIES: TECHNIQUES AND TACTICS FOR SUCCESS(2012) PAULOS, Renata Gregorio; SIMAO, Danielle Tiemi; MATTAR JUNIOR, Rames; REZENDE, Marcelo Rosa de; WEI, Teng Hsiang; TORRES, Luciano RuizObjectives: Retrospective evaluation of cases of limb replantation after avulsion injuries. Evaluation of the techniques and tactics used, that contributed to success and good functional results. Methods: Forty-three patients' records were assessed. All the cases had been submitted to limb replantation after avulsion injuries. Results: The majority of the cases were young men. The most common injury was to the thumbs. The surgical techniques and tactics used were: nerve grafting, vein grafting, transposition of the digital vessels, limb shortening, and heterotopic replantation. The most commonly used technique was vein graft. The limb survival rate was high (93%), as was patient satisfaction. Conclusion: Replantation after avulsion injury depends on the correct diagnosis of the limb viability and the use of appropriate surgical techniques and tactics for each case. The experience of the team of surgeons and a good hospital structure are essential for good results. There are few articles in medical literature about the indications, techniques and results of limb replantation after avulsion injuries. We believe that this retrospective evaluation can bring new information and contributions to the correct management of this highly complex situation. Level of evidence IV, Case Series.
