RESUMEN
Introdução: O retalho em hélice, ou propeller flap, é um tipo de retalho local baseado em vasos perfurantes. Apresenta diversas vantagens, como a reconstrução de tecidos semelhantes ao original, menor morbidade da área doadora, manutenção dos principais vasos da região e a possibilidade de amplo arco de rotação (até 180º). Entretanto, está sujeito a complicações, sendo a mais preocupante a necrose parcial ou total do retalho. Métodos: Estudo retrospectivo de uma série de três casos de sequelas de trauma em membros inferiores tratados com retalho em hélice. Resultados: Retalhos em hélice reduzem o tempo cirúrgico, dias de internação e custos. Todavia, não são isentos de complicações, encontra-se a ocorrência de necrose parcial de 10,5 a 11% e total de 1 a 5%. Outras complicações descritas são epidermólise (3,5%) e congestão venosa transitória (3%). Nos casos descritos, evoluíram sem complicações. Classicamente, os defeitos de membro inferior, principalmente no terço distal, têm indicação de reconstrução com retalhos microcirúrgicos. Conclusão: Os retalhos propeller podem ser uma alternativa nestes casos, principalmente em defeitos pequenos e moderados. Ainda não existem trabalhos comparando diretamente estas duas técnicas, mas algumas informações importantes já estão disponíveis, como a semelhança entre os percentuais de necrose total entre as técnicas.
Introduction: The propeller flap is a type of local flap based on perforating vessels. It has several advantages, such as the reconstruction of tissues similar to the original, less morbidity of the donor area, maintenance of the main vessels of the region and the possibility of a wide rotation arc (up to 180º). However, it is subject to complications, the most worrisome being partial or total necrosis of the flap. Methods: A retrospective study of a series of three cases of lower limb trauma sequelae treated with helix flaps. Results: Helical flaps reduce surgical time, hospitalization days, and costs. However, they are not free of complications, with partial necrosis occurring in 10.5 to 11% and total necrosis in 1 to 5%. Other complications described are epidermolysis (3.5%) and transient venous congestion (3%). In the cases described, they evolved without complications. Classically, lower limb defects, especially in the distal third, are indicated for reconstruction with microsurgical flaps. Conclusion: Propeller flaps may be an alternative in these cases, especially in small and moderate defects. There are still no studies directly comparing these two techniques, but some valuable information is already available, such as the similarity between the percentages of total necrosis between the techniques.
RESUMEN
Introdução: A transposição de veia cefálica é uma alternativa interessante como veia doadora na reconstrução oncológica de cabeça e pescoço em pacientes com história de radioterapia cervical. O objetivo do trabalho é avaliar as características anatômicas da veia cefálica em cadáveres. Métodos: Foram dissecadas seis veias cefálicas de três cadáveres. As veias foram seccionadas na parte medial do braço e transpostas até o pescoço por cima das clavículas. Resultados: As veias apresentaram média de comprimento de 18,75±1,84cm e número de tributárias com variação de 7-9. O diâmetro coincidiu em ambas as veias de cada cadáver. O parâmetro anatômico usado para identificálas (sulco deltopeitoral) se mostrou confiável, possibilitando uma dissecação previsível. Conclusão: A veia cefálica tem características constantes e fácil localização, sendo uma opção relevante ao arsenal terapêutico do cirurgião plástico reconstrutor.
Introduction: Cephalic vein transposition is an interesting alternative as a donor vein in head and neck cancer reconstruction in patients with a cervical radiotherapy history. This work aims to evaluate the cephalic vein anatomical characteristics in cadavers. Methods: Six cephalic veins from three cadavers were dissected. The veins were sectioned in the medial part of the arm and transposed to the neck over the clavicles. Results: The veins had an average length of 18.75 ± 1.84 cm and several tributaries with a variation of 7-9. The diameter coincided in both veins of each corpse. The anatomical parameter used to identify them (deltopectoral groove) proved reliable, allowing predictable dissection. Conclusion: The cephalic vein has constant characteristics and is easy to locate, being an option relevant to the reconstructive plastic surgeon's therapeutic arsenal.
RESUMEN
Introdução: A reconstrução mamária imediata com expansor/ implante permanece uma opção importante para mulheres submetidas à mastectomia. O objetivo desse estudo foi avaliar os resultados de reconstrução mamária imediata com emprego expansores e implantes em pacientes submetidas à radioterapia e não submetidas à radioterapia no pós-operatório. Métodos: Foi realizado estudo prospectivo consecutivo com 83 mulheres submetidas à reconstrução mamária imediata com expansores seguido de implantes no período de 2007 a 2012, totalizando 90 reconstruções. No primeiro tempo cirúrgico, o expansor foi colocado em uma bolsa submuscular sob os músculos peitoral maior e serrátil. No segundo tempo, o expansor foi substituído pela prótese. Dois grupos de pacientes foram comparados: (1) pacientes que receberam radioterapia no pós-operatório e (2) pacientes que não receberam radioterapia no pós-operatório. Os resultados foram avaliados em cada grupo nos dois tempos cirúrgicos. Resultados: Trinta e três pacientes receberam tratamento radioterápico (39,8%) no final da expansão. Observamos a ocorrência de 13,25% de complicações no primeiro tempo: deslocamento do expansor (4,8%), esvaziamento (2,4%), infecção (2,4%), deiscência de pele (2,4%) e extrusão (1,2%). No segundo tempo, as complicações foram 17,6%: contratura capsular (7%), extrusão (5,3%), e infecção (5,3%). Com relação aos grupos estudados no primeiro tempo, aqueles que fizeram radioterapia tiveram (18,18%) de complicações e o grupo não exposto à radioterapia apenas (10,0%). No segundo tempo, encontramos 7 (46,6%) complicações para radioterapia e apenas 3 (7,14%) para o grupo não irradiado. Conclusões: Pacientes que receberam radioterapia posteriormente à reconstrução apresentaram maiores índices de complicações.
Introduction: Immediate breast reconstruction with an expander/implant is a good option for women submitted to mastectomy. This study aimed to evaluate the results of immediate breast reconstruction with implants and expanders in patients who did or did not undergo postoperative radiotherapy. Methods: A consecutive prospective study that involved 83 women submitted to immediate breast reconstruction, was carried out by first performing breast reconstruction surgery with expanders and then with implants. The study was conducted between 2007 and 2012 and accounted for a total of 90 reconstructions. In the first surgery, an expander was placed in a submuscular bag under the pectoralis major and serratus muscles. In the second surgery, the expander was replaced by an implant. We compared the surgical outcomes of both types of surgeries (with implants and with expanders) in patients who underwent postoperative radiotherapy and those who did not. Results: After the first surgery, 33 patients (39.8%) received radiotherapy, and 13.25% experienced complications, including expander displacement (4.8%), emptying (2.4%), infection (2.4%), skin dehiscence (2.4%), and extrusion (1.2%). After the second surgery, 17.6% of the subjects experienced complications, including capsular contracture (7%), extrusion (5.3%), and infection (5.3%). With regard to the first surgery, 18.8% of the patients who underwent radiotherapy and 10.0% of those who did not, experienced complications. With regard to the second surgery, these prevalences were 46.6 % and 7.14%, respectively. Conclusion: Patients who received radiotherapy after breast reconstruction surgery experienced more complications.

BACKGROUND: Recurrent rectus diastasis is a troublesome complication because its correction requires an extensive procedure. CASE REPORTS: Two patients with recurrent rectus diastasis secondary to abdominoplasty corrected by plication of the anterior rectus sheath are presented. These patients had lateral insertion of the rectus muscles. They were treated by the advancement of the rectus muscles after undermining of the posterior rectus sheath and a two-layer closure to correct the rectus diastasis. Good cosmetic results and postoperative pain control were achieved in both cases. DISCUSSION: The causes, prevention, and treatment for this type of rectus diastasis are described. The main reason for recurrence of this deformity in these patients was lateral insertion of the rectus muscles on the costal margins. On the basis principle, an efficient technique to correct this deformity is described. A postoperative compute tomography scan with slices made at the same bony level as the preoperative control examination demonstrated total correction of rectus diastasis over a long-term follow-up evaluation. CONCLUSION: Advancement of the recti muscles seems to be a reliable method for correcting recurrent rectus diastasis in patients with lateral insertion of the recti muscles.

Abdominal skin hypesthesia may occur after abdominoplasty. The purpose of this study was to find out (1) which sensibility modalities are decreased and (2) which areas of the abdominal wall are affected, so that patients can be warned preoperatively about this condition. Forty patients were divided in two groups of 20 patients each. In the control group, patients had no previous abdominal incisions. The sensibility evaluation of patients from the experimental group was made from 12 to 60 months after abdominoplasty, with an average of 31.5 months. These patients were divided into two groups of 10 patients each, a short-term follow-up group (12 to 30 months postoperatively) and a long-term follow-up group (31 to 60 months postoperatively). The abdominal skin was divided into 12 areas; nine were above the abdominoplasty incision and three were below it. Sensibility to superficial touch, superficial pain, and hot and cold modalities was recorded as positive in all areas by a variable number of patients of the experimental group. However, in area 8 (hypogastric area), a statistically significant number of patients had decreased sensibility in all sensibility modalities (Fisher's test and t test). Patients in the experimental group also showed decreased sensibility to hot and cold temperature in area 11 (pubic area). Sensibility to pressure decreased significantly in all areas of the abdomen when compared with the control group (t test). When patients of the short-term follow-up group were compared with those of the long-term follow-up group, there was no statistically significant difference for all modalities of sensibility in the areas studied, except for area 5. In this area it was found that long-term follow-up patients recovered sensibility to cold and hot temperatures. These findings help plastic surgeons to orient their patients about possible risk of exposure to injuries in the areas with decreased sensibility after abdominoplasty. Most importantly, as these patients have decreased sensibility to pressure and hot temperature in a more extensive area of the abdomen, they are exposed to a higher risk of burn injury.

No periodo de 1977 a 1991 foram operados 23 pacientes, 15 femininos e oito masculinos, com idades entre oito e 42 anos portadores de depressoes faciais por atrofia hemifacial em oito, microssomia hemifacial em quatro e sequela de hemangioma em um caso. Utilizamos 25 retalhos microcirurgicos: 12 paraescapulares, cinco epiploons, retalhos do musculo grande dorsal e um tensor de fascia lata. Houve bom resultado em 21 dos 23 pacientes, com restabelecimento de simetria facial adequada. Houve duas perdas por trombose vascular, um dos quais recebeu um segundo transplante com bom resultado. Em dois pacientes, tardiamente, apos a integracao do retalho houve perda do volume transplantado. Este achado, importante do ponto de vista de fisiopatologia e especificamente abordado na discussao. Comparando os resultados das varias formas de tratamento conclui-se que os transplantes dermogordurosos microcirurgicos sao os mais indicados para a correcao permanente das depressoes faciais congenitas ou adquiridas.
