Retrospective analysis of a case series of patients with traumatic injuries to the craniocervical junction / Análise retrospectiva de série de casos com lesões traumáticas da junção craniocervical

ABSTRACT Objective To evaluate the correlation between the treatment, the characteristics of the lesions and the clinical outcome of patients with traumatic injuries to the craniocervical junction. Methods This was a retrospective study of patients treated conservatively or surgically between 2010 and 2013 with complete data sets. Results We analyzed 37 patients, 73% were men with mean age of 41.7 years. Of these, 32% were submitted to initial surgical treatment and 68% received conservative treatment. Seven (29%) underwent surgery subsequently. In the surgical group, there were seven cases of odontoid type II fractures, two cases of fracture of posterior elements of the axis, one case of C1-C2 dislocation with associated fractured C2, one case of occipitocervical dislocation, and one case of combined C1 and C2 fractures, and facet dislocation. Only one patient had neurological déficit that improved after treatment. Two surgical complications were seen: a liquoric fistula and one surgical wound infection (reaproached). In the group treated conservatively, odontoid fractures (eight cases) and fractures of the posterior elements of C2 (five cases) were more frequent. In two cases, in addition to the injuries of the craniocervical junction, there were fractures in other segments of the spine. None of the patients who underwent conservative treatment presented neurological deterioration. Conclusion Although injuries of craniocervical junction are relatively rare, they usually involve fractures of the odontoid and the posterior elements of the axis. Our results recommend early surgical treatment for type II odontoid fractures and ligament injuries, the conservative treatment for other injuries.

RESUMO Objetivo Avaliar a correlação entre o tratamento, as características das lesões e o resultado clínico em pacientes com lesões traumáticas na junção craniocervical. Métodos Estudo retrospectivo de pacientes maiores de 18 anos tratados de forma conservadora ou cirúrgica, entre 2010 e 2013. Resultados Foram analisados 37 pacientes, 73% eram do sexo masculino e a média de idade foi de 41,7 anos. Inicialmente 32% dos pacientes foram submetidos a tratamento cirúrgico, e 68% foram submetidos a tratamento conservador. Sete pacientes (29%) do grupo conservador foram submetidos posteriormente à cirurgia. No grupo cirúrgico, houve sete casos de fratura de odontóide tipo II, dois casos de fratura de elementos posteriores do áxis, um caso de luxação C1-C2, um caso de deslocamento occipito-cervical e um caso de fraturas de C1 e C2 e luxação facetária. Um paciente apresentava déficit neurológico, melhorando após o tratamento. Houve duas complicações pós-cirúrgicas, uma fístula liquórica e uma infecção de ferida operatória (reabordada). No grupo conservador, predominaram as fraturas do odontóide (oito) e dos elementos posteriores de C2 (cinco). Em dois casos, havia também fraturas em outros segmentos da coluna. Nenhum dos pacientes deste grupo apresentou deterioração neurológica. Conclusão As lesões da junção craniocervical são raras, sendo mais frequentes as fraturas do odontóide e dos elementos posteriores do áxis. Nossos resultados recomendam o tratamento cirúrgico precoce para os pacientes com fraturas do odontóide tipo II e lesões ligamentares, e tratamento conservador para os demais pacientes.

Terapia por pressão negativa na ferida traumática complexa do períneo / Negative pressure wound therapy in complex trauma of perineum

OBJETIVO: rever a experiência (2011 e 2012) do Centro de Feridas da Cirurgia Plástica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo com tratamento de feridas traumáticas complexas na região perineal, pela associação da terapia com pressão negativa seguida de procedimento cirúrgico para cobertura cutânea. MÉTODOS: análise retrospectiva de dez pacientes com ferida complexa no períneo consequente a traumatismo atendidas pelo Serviço de Cirurgia Plástica no HC-FMUSP. A terapia por pressão negativa foi utilizada como alternativa para melhoria das condições locais visando o tratamento definitivo com enxertos de pele ou retalhos. RESULTADOS: a terapia por pressão negativa foi empregada para o preparo do leito da ferida. Nos pacientes atendidos, o tempo médio de utilização do sistema de pressão negativa foi 25,9 dias, com trocas de curativos a cada 4,6 dias. Após a terapia por pressão negativa, foram realizados 11 retalhos locais em nove pacientes, com o retalho fáscio-cutâneo antero-lateral da coxa utilizado em quatro destes pacientes. O tempo médio de internação hospitalar foi 58,2 dias e de acompanhamento no Serviço da Cirurgia Plástica foi 40,5 dias. CONCLUSÃO: a utilização da terapia por pressão negativa levou à melhoria das condições locais da ferida mais rapidamente do que curativos tradicionais, sem complicações significativas, demonstrando ser a melhor alternativa adjuvante atualmente para o tratamento deste tipo de lesão, seguida sempre por reconstrução cirúrgica com enxertos e retalhos.

OBJECTIVE: To review the experience (2011 and 2012) of Wound Center of Plastic Surgery Service, Clinics Hospital, Faculty of Medicine, University of São Paulo, with treatment of complex traumatic wounds in the perineal region with the association of negative pressure wound therapy followed by a surgical skin coverage procedure. METHODS: This was retrospective analysis of ten patients with complex wound in the perineum resulting from trauma assisted by the Department of Plastic Surgery in HC-USP. Negative pressure was used as an alternative for improving local conditions, seeking definitive treatment with skin grafts or flaps. RESULTS: Negative pressure was used to prepare the wound bed. In patients, the mean time of use of negative pressure system was 25.9 days, with dressing changes every 4.6 days. After negative pressure therapy, 11 local flaps were performed in nine patients, with fasciocutaneous anterolateral thigh flap used in four of these. Mean hospital stay was 58.2 days and accompaniment in Plastic Surgery was 40.5 days. CONCLUSION: The use of negative pressure therapy led to improvement of local wound conditions faster than traditional dressings, without significant complications, proving to be the current best alternative as an adjunct for the treatment of this type of injury, always followed by surgical reconstruction with grafts and flaps.

Surgical treatment of traumatic tricuspid insufficiency / 中华胸心血管外科杂志

Objective To summarize the timing, procedure and early and late outcomes of Surgical treatment of traumatic tricuspid insufficiency. Methods From May 1984 through September 2004, eight patients with traumatic tricuspid insufficiency were treated surgically. All were male, and the ages ranged from 7 to 67 years (median 38 years). Seven patients were blunt chest trauma (including traffic accidents in three). The median duration between trauma and operation was 19 months (range 1 month to 20 years). At operation, the heart functions of patients were in class II to IV (NYHA). Diagnoses were conformed by echocardiogram. The anterior leaflet was prolapsed because of the rupture of chord or anterior papillary muscle in all the patients, combined with chordal rupture of septal leaflet in one. In all the patients, right ventricular was enlarged in various degrees, as well as tricuspid annulus. In three patients, the tricuspid valve was repaired. Five cases received valve replacement, after repair failed. Results All the patients were recovered well without complication after operation. Only one of the three patients after tricuspid valve repair was detected mild tricuspid regurgitation by echocardiogram. The mean postoperative hospital stay was (16.6?6.5) days (7 to 24 days). The median follow-up period was 39 months (range 7 to 129 months). The heart functions were improved to class I (NYHA) in all patients. Conclusion The outcome of surgical treatment of traumatic tricuspid valve insufficiency is good. Surgical intervention should be done as early as possible once diagnosis was made to increase the feasibility of tricuspid valve repair. Tricuspid valve repair is the procedure of choice, while tricuspid valve replacement is also acceptable according to the long-term result of this report.
