- INTERCOSTAL NERVE TRANSFER TO THE BICEPS MOTOR BRANCH IN COMPLETE TRAUMATIC BRACHIAL PLEXUS INJURIES(2015) BAIK, Alvaro; IAMAGUCHI, Raquel Bernardelli; SILVA, Gustavo Bersani; PAULOS, Renata Gregorio; KIYOHARA, Leandro Yoshinobu; SORRENTI, Luiz; MENEZES, Klicia de Oliveira Costa Riker Teles de; REZENDE, Marcelo Rosa de; WEI, Teng Hsiang; MATTAR JUNIOR, RamesThe purpose of this report is to critically evaluate our results of two intercostal nerve transfers directly to the biceps motor branch in complete traumatic brachial plexus injuries. From January 2007 to November 2012, 19 patients were submitted to this type of surgery, but only 15 of them had a follow-up for >= 2 years and were included in this report. The mean interval from trauma to surgery was 6.88 months (ranging from 3 to 9 months). Two intercostals nerves were dissected and transferred directly to the biceps motor branch. The mean follow-up was 38.06 months (ranging from 24 to 62 months). Ten patients (66.6%) recovered an elbow flexion strength >= M3. Four of them (26.66%) recovered a stronger elbow flexion >= M4. One patient (6.25%) recovered an M2 elbow flexion and four patients (26.66%) did not regain any movement. We concluded that two intercostal nerve transfers to the biceps motor branch is a procedure with moderate results regarding elbow flexion recovery, but it is still one of the few options available in complete brachial plexus injuries, especially in five roots avulsion scenario.

- A REINFORCEMENT OF THE SUTURED MICROVASCULAR ANASTOMOSIS WITH FIBRIN GLUE APPLICATION: A RETROSPECTIVE COMPARATIVE STUDY WITH THE STANDARD CONVENTIONAL TECHNIQUE(2017) CHO, Alvaro Baik; PAULOS, Renata Gregorio; BERSANI, Gustavo; IAMAGUCHI, Raquel Bernardelli; TORRES, Luciano Ruiz; WEI, Teng Hsiang; RESENDE, Marcelo Rosa De; MATTAR JUNIOR, RamesPurpose: Although a reasonable number of studies report satisfactory results with fibrin glue application in microvascular anastomosis since 1977, its utilization in the clinical setting has being scant in the literature. The aim of this study was to report the cumulated experience with the fibrin glue in free flaps over a period of 10 years, comparing the survival rate with the standard sutured anastomosis. Patients and methods: From August 2001 through November 2014, 83 consecutive free flaps were performed by a team of surgeons from two hospitals. About 56 flaps were performed in 56 patients using the fibrin glue augmented microvascular anastomosis and 27 flaps were performed in 27 patients using the conventional anastomosis technique. The decision on whether or not the fibrin glue should be used at the anastomoses was based on its availability and whose surgeon was performing the anastomoses. About approximately 60% of sutures stitches were used that would be used in a conventional anastomosis, when fibrin glue application was anticipated (ranging from 5 to 7 sutures in the arteries and 5 to 8 in the veins). Results: The overall survival rate of the flaps performed with fibrin glue application was 92.85%. In one case, a revision of the venous anastomosis was required due to early flap congestion. Four cases (7.14%) had failure of the first free flap and two of them were submitted to another free flap without fibrin glue application. In the flaps performed with the conventional anastomosis technique the survival rate was 92.59%. This difference was not statistically significant (P=0.97). Conclusion: The application of fibrin glue in microvascular anastomoses did not increase the rate of flap loss and had a potential to reduce the number of sutures required to complete an anastomosis by its sealing effect.
