A single-center retrospective analysis of 77 traumatic arterial injuries of lower extremities / 中华外科杂志

Objective: To analyze the treatment and clinical prognosis of lower extremity arterial injury caused by trauma. Methods: The clinical data of 77 patients with traumatic lower extremity arterial injury admitted to Department of Vascular Surgery,Yichang Central People's Hospital from January 2013 to June 2021 were collected retrospectively. There were 65 males and 12 females, with an average age of 47.4 years (range: 7 to 75 years). Among the 77 patients, 56 cases (72.7%) had open injury and 21 cases (27.3%) had closed injury. Iliac artery was injured in 9 cases (11.7%), common femoral artery in 7 cases (9.1%), superficial femoral artery in 1 case (1.3%), popliteal artery in 11 cases (14.3%) and inferior knee artery in 49 cases (63.6%). The treatment methods and clinical effects were analyzed. Results: One case with pelvic fracture combined the internal iliac artery injury and 1 case with multiple injuries involving the common femoral artery died of circulatory failure before surgery. Seventy-five cases received vascular-related operations, including arterial ligation in 24 cases, arterial reconstruction in 40 cases, stent graft implantation in 1 case, primary amputation in 2 cases, and arterial embolization in 8 cases. The overall mortality rate was 6.5% (5/77), all of which were closed injuries. Except for 2 cases who died before surgery, 3 cases with pelvic fracture combined the internal iliac artery injury died of multiple organ failure after internal iliac artery embolization. There were 8 cases received amputation (10.4%, 8/77), 5 cases with closed injury and 3 cases with open injury. In addition to 2 cases with primary amputation, 6 cases underwent secondary amputation due to ischemia-reperfusion injury after revascularization (4 cases with popliteal artery injury and 2 cases with subpatellar artery injury). The average followed-up time was 17 months (range: 2 months to 8 years). One patient with femoral artery injury underwent autologous great saphenous vein bypass, and lower limb artery CT angiography was re-examined 6 months after the operation, and 30% distal anastomotic stenosis was found. Ankle brachial index<0.8 was found in two patients 1 year after popliteal artery repair, but none of the patients had intermittent claudication symptoms, and no further intervention was performed. Five patients suffered delayed healing due to severe lower limb injury, fracture and skin injury. Among them, 2 cases had poor wound healing at the stump of amputation, which gradually healed 3 to 5 months after several debridements. The other 3 vascular injury combined with tibial fracture patients had delayed tibial healing after surgery, but no symptoms of vascular ischemia occurred. All the other patients recovered well and no other serious complications occurred. Conclusions: The proportion of death and disability in patients with lower limb artery injury caused by trauma is high. Active and orderly surgical repair according to the site and type of injury can reduce the mortality, save the function of the affected limb, and promote the healing of injury.

Resumo O tamanduá-bandeira é um mamífero encontrado na América Central e na América do Sul. Esse animal possui garras que podem chegar a 6,5 cm de comprimento, utilizadas para escavar formigueiros e obter alimento, além de servir para sua defesa. Relatamos o caso de paciente masculino de 52 anos, com histórico de epilepsia, que foi levado desacordado ao pronto-socorro, devido a lesões no seu braço direito causadas por um tamanduá. Frente à suspeita de trauma vascular, o paciente foi submetido a exploração cirúrgica, que evidenciou uma lesão combinada de vasos braquiais, submetida a reparo. Apresentou boa evolução do quadro, recebendo alta hospitalar no segundo dia de pós-operatório e, no seguimento ambulatorial, evoluiu sem sequelas neurológicas ou vasculares.

Abstract The giant anteater is a mammal found in Central and South America. These animals have claws that can reach 6.5 centimeters in length, which they use to dig anthills to obtain food and for defense. We report the case of a 52-year-old male patient with a history of epilepsy who was taken unconscious to the emergency room due to injuries to his right arm caused by an anteater. He underwent surgical exploration to investigate suspected vascular trauma, revealing a combined (arterial and venous) injury of the brachial vessels, which were repaired. He recovered well and was discharged on the second postoperative day. During outpatient follow-up he continued to improve, with no neurological or vascular sequelae.

Patient survival and limb salvage after shark attack with major vascular injury: A case report / 中华创伤杂志(英文版)

Shark attacks are rare unique pathological processes. Some of them represent devastating injuries with a high morbidity and significant mortality. Related published articles are limited. The increased human interaction within the environment of sharks is the cause of rising incidence of such attacks. This study reported a case of level 4 shark injuries (shark-induced trauma scale) in a 33-year-old male patient, who presented with an extensive injury of the right lower limb with the characteristic features of shark bite. At admission the patient was in a state of shock with profuse bleeding that was controlled by tourniquet. The patient was resuscitated according to the advanced trauma life support. Clinical examination showed hard signs of vascular injury with absent pedal pulse, associated neurological deficits and severance at the knee joint. Prompt vascular intervention after resuscitation was performed to manage the major vascular injuries, together with proper washout and debridement of all the necrotic tissues under strong antibiotic coverage to prevent infection. After that, the patient underwent sequenced plastic, orthopedic, and neurological interventions. Strict follow-up was conducted, which showed that the patient was saved and achieved a functioning limb. This study aims to highlight the management of level 4 shark injuries, which are considered serious and challenging with a high fatality rate and a great risk of amputation due to the associated major vascular injuries. Immediate well organized management plan is crucial. Prompt resuscitation and surgical intervention by a highly-skilled medical team are required to improve the chance of patient survival and limb salvage.

Luxación expuesta de rodilla: ¿Qué hemos aprendido en los últimos 20 años? / Open knee dislocations: what have we learn about it in the last 20 years?

INTRODUCCIÓN: La luxación expuesta de rodilla es compleja, de incidencia baja con grandes secuelas funcionales. Existen escasos reportes de series en la literatura relativos a su manejo y resultados. OBJETIVO: El objetivo de este trabajo fue describir los resultados obtenidos de todos los pacientes con luxación expuesta de rodilla tratados durante las últimas dos décadas en nuestro hospital bajo un mismo estándar de tratamiento. MÉTODO: Estudio descriptivo retrospectivo en una serie quirúrgica de 11 pacientes con luxación expuesta de rodilla, tratados entre 1994 y 2015. Todos fueron estudiados y manejados según esquema estandarizado: Angiografía/ angioTC, aseo quirúrgico, fijador externo y reparación neurovascular en casos necesarios. Revisión de registros clínicos e imagenológicos consignando datos demográficos, lesiones concomitantes, número y tipo de cirugías, y complicaciones asociadas. Seguimiento promedio fue de 10,7 años con evaluación mediante encuesta funcionales SF-12/IKDC durante el mes de marzo de 2015. RESULTADOS: Diez pacientes eran hombres, 1 mujeres. Edad promedio al accidente 38,6 años. Mecanismo lesional de alta energía; como referencia la clasificación de Schenck, 1 lesión III-M, 4 tipo IV y los 6 restantes una tipo V. 4 lesiones vasculares (36.4%) y 7 lesiones neurológicas (63.6%). Tratamiento definitivo consistió en 4 reconstrucciones ligamentarias, 2 prótesis, 3 artrodesis y 2 amputaciones supracondíleas. Evaluaciones funcionales dieron como resultados un puntaje promedio de 37 y 48,5 para SF-12 físico y mental respectivamente, y de 44,1 para IKDC. CONCLUSIÓN: La luxación expuesta de rodilla es una lesión infrecuente, muy compleja, asociada a accidentes de alta energía, con complicaciones severas, lo que determina resultados funcionales relativamente malos. La estandarización permite sistematizar las distintas etapas de atención, racionalizar los recursos disponibles evitando la improvisación en momentos críticos, lo que podría incidir en la obtención de resultados.

INTRODUCTION: Open knee dislocation is a complex lesion of low incidence and large functional sequelae. There are few series reports in the literature regarding its management and outcomes. OBJECTIVE: Describe the results obtained from all patients with open knee dislocation treated during the last two decades in our hospital under the same treatment standard. METHOD: Retrospective descriptive study in a surgical series of 11 patients with open knee dislocation, treated between 1994 and 2015. All were studied and managed according to a standardized protocol: Angiography/angioCT, surgical debridement, external fixation and neurovascular repair in necessary cases. Review of clinical and imaging records, recording demographic data, concomitant injuries, number and type of surgeries and associated complications. Average follow-up was 10.7 years, with an evaluation through functional surveys SF-12/IKDC during March 2015. RESULTS: 10 patients were men, 1 woman. Average age at accident 38.6 years. High-energy trauma mechanism of injury; Schenk classification as reference, 1 lesion type III-M, 4 type IV and the remaining 6 type V. 4 vascular lesions (41.7%) and 7 neurological lesions (63.6%). Definitive treatment consisted in 4 ligamentous reconstructions, 2 prostheses, 3 arthrodesis and 3 supracondylar amputations. Functional evaluations showed an average score of 37 and 48.5 for SF-12 physical and mental respectively, and 44.1 for IKDC. CONCLUSION: Open knee dislocation is a rare, very complex, associated to high-energy trauma, with severe complications, which determines relatively poor functional outcomes. Standardization allows to systematize the different stages of attention and rationalize available resources avoiding improvisation at critical moments, which could affect the results.

Utilización de la ultrasonografía y aplicación del Doppler para la evaluación de ejes vasculares periféricos y la prevención del síndrome compartimental / Using ultrasonography and doppler application for evaluating vascular axes and prevention of compartmental syndrome

La ultrasonografía es un método de evaluación rápido y eficaz en los departamentos de emergencias, siempre en manos entrenadas. La lesión vascular periférica es un cuadro que en lo que trauma se refiere, debe tener un veloz diagnóstico y tratamiento por los riesgos que significa: En lesiones abiertas, la hemorragia; y en lesiones cerradas se añade el síndrome compartimental. Lograr la evaluación de la indemnidad o no del árbol vascular en los miembros, se torna importante a la hora de prevenir eventos que requieran intervención quirúrgica (reparación y/o fasciotomía). El objetivo de este trabajo consiste en demostrar la utilidad del conocimiento del árbol vascular periférico y su evaluación mediante doppler para el manejo del traumavascular periférico, utilizando listas de verificación para la evaluación sistemática de la vasculatura. Se realiza-ron evaluaciones sistemáticas a 10 residentes de cirugía general, utilizando primero modelos inanimados y animados y luego se evaluaron en situaciones de guardia, dividido en periodos (febrero/abril 2016 y mayo/agosto 2016). Se correlacionaron los hallazgos con lo estipulado en la lista de verificación previamente realizada y se estableció la relación posterior con el desarrollo del síndrome compartimental. Se evaluaron 185 modelos animados: 1era evaluación: Reconocimiento de estructuras >60 %= 6 residentes. >80 %= 4 residentes. 2da evaluación: Reconocimiento de estructuras >60 %= 3 residentes. >80 %= 7 residentes. En la atención del politraumatizado: reconocimiento de estructuras >60 %= 3 residentes. >80%= 7 residentes. Pacientes con riesgo de síndrome compartimental (n=77) = 11 (14,78 %). Resolución: lesión vascular = 1 (1,3 %) síndrome compartimental= 1 (1,3 %) con resolución quirúrgica. La utilización de la ultrasonografía y del doppler para la evaluación vascular periférica es útil para el reconocimiento precoz del riesgo a desarrollar desde una lesión vascular simple hasta un síndrome compartimental. La utilización de listas de verificación durante la simulación para la generación del criterio, son útiles en la formación de residentes de cirugía.

Ultrasonography is with adequate training, a fast and effective evaluation method in emergency departments. Peripheral vascular injury is frequent in trauma and should have a rapid diagnosis and treatment, as risks include: open sores, bleeding; closed injuries and compartmental syndrome. Prompt evaluation of the integrity in the vascular tree becomes important in preventing events that require surgical intervention (repair and / or fasciotomy). The aim of this work is to demonstrate the usefulness of knowledge of peripheral vascular tree, ultrasound evaluation and Doppler for peripheral vascular trauma management,using checklists for the systematic evaluation of the vasculature. Systematic evaluations were realized in 10general surgery residents. Initially, using inanimate and animate models which were then evaluated intrauma situations. Divided into periods (February / April 2016 ­ May/August 2016). The findings with previouscriteria made the verification list and subsequent connection with the development of compartment syndromethat were established by correlation. Evaluation animated models: 1st assessment: Recognition of structures>60 % =6 residents. > 80 % =4 residents. The 2nd assessment: Recognition of structures > 60 % = 3residents. > 80 % = 7 residents. In the care of multiple trauma: recognition structures > 60% =3 residents.>80 % =7 residents. Patients at risk for compartmental syndrome (n=77)=11 (14.78 %). Resolution:Vascular Lesion 1 (1.3 %) compartmental syndrome: 1 (1.3 %) with surgical resolution. The use of ultrasonography and Doppler for peripheral vascular evaluation is useful for early recognition of risk from developing a single vascular lesion, to compartmental syndrome. The use of the checklists during simulation for the generation of criteria is useful in the training of surgical residents

Utilizando una técnica de entrelazado con elásticos vasculares se realizó el cierre de las fasciotomías. En el 2010 se publicó un reporte preliminar, presentando una serie de 56 fasciotomías cerradas con esta técnica, con un promedio de cierre de 9,5 +/- 3,31 días. La serie actual es el resultado de un estudio prospectivo de 4 años de duración que ha buscado demostrar que resulta posible asociar esta técnica con elásticos al manejo inicial del cierre de las fasciotomías. Nuestro reporte final muestra un total de 122 fasciotomías cerradas en un promedio de 7,9 +/- 3,31 días sin requerir de injertos de piel. Conclusiones: Presentamos una técnica quirúrgica fácil de reproducir, de bajo costo y con buenos resultados. El uso de elásticos vasculares muestra beneficios en el tiempo de cierre de las fasciotomías.

Trauma vascular: nuestra experiencia en los últimos 10 años / Trauma vascular- nossa experiência nos últimos 10 anos. / Vascular trauma: ouer experience in the last 10 years

Antecedentes: El incremento de la violencia ciudadana por el uso de armas de fuego y blancas en delitos comunes y los accidentes por exceso de velocidad sin medidas de seguridad adecuadas, han producido un aumento en la incidencia de los traumas vasculares, siendo la mayor causa de muerte en pacientes jóvenes. Objetivo: Demostrar nuestra casuística y experiencia en el manejo del trauma vascular así como su resolución. Diseño: Análisis descriptivo y retrospectivo de los últimos 10 años. Material y Método: 470 pacientes se tra taron desde el 1 de enero de 2000 hasta el 31 diciembre del 2009. Se analizó la composición demográfica, el mecanismo lesional, la región afectada y la técnica quirúrgica utilizada. El 86,6% fue de sexo masculino y el 13,4% de sexo femenino. La edad promedio fue de 26,9 años. El 69,5% presentaron trauma penetrante y el 30,5% trauma contuso. El 4,5% presentaron lesiones de cuello, 12% torácicas, 14,9% lesiones abdominales y nuestra mayor casuística fue la lesión de los miembros: 68,6%. En 175 pacientes, la técnica fue el bypass (119 venosos y 56 protésicos ). 206 pacientes recibieron resección y anastomosis término-terminal y 36 pacientes fueron tratados con ligadura primaria. Como métodos endovasculares se colocaron 5 endoprótesis por ruptura traumática de aorta torácica, 3 stents periféricos y se realizó un reimplante de mano. Resultados: La mortalidad global fue del 7,8% (37 pacientes) en la mayoría de los casos debido al politrauma, Crush síndrome, SIRS y/o shock séptico. En cuanto a los pacientes con RTAT, uno presentó óbito por falla del material. El 9,1% de los pacientes sufrieron amputación del miembro (38 pacientes) de los cuales 9 fueron por arrancamiento del miembro, 11 amputaciones primarias y 18 secundarias. Del total de pacientes que presentaron lesiones vasculares de los miembros, 60 (5,8%) recibieron fasciotomía pre, intra o post-revascularización. Conclusiones: Nuestra aceptable morbimortalidad depende de la rapidez y ...

Antecedentes: O aumento da violência nas cidades, o uso de armas de fogo e armas brancas em delitos comuns, e os acidentes por excesso de velocidade sem medidas de segurança adequadas, têm produzido um aumento na incidência dos traumas vasculares, sendo esta, a maior causa de morte em pacientes jovens. Objetivo: Demonstrar nossa especificidade e experiência no tratamento do trauma vascular, como também em sua resolução. Desenho: Análise descritiva e retrospectiva dos últimos 10 anos. Material e Método: 470 pacientes foram tratados de 1º de janeiro de 2000 a 31 de dezembro de 2009. Analisou-se a composição demográfica, o mecanismo de lesão, a região afetada e a técnica cirúrgica utilizada. 86, 6 % dos pacientes eram do sexo masculino e 13,4 % do sexo feminino. A idade média foi de 26,9 anos. 69,5 % apresentaram trauma penetrante e 30,5 % trauma contuso. 4,5 % apresentaram lesões no pescoço, 12 % torácicas, 14,9 % lesões abdominais e a nossa maior especificidade, em 68,6% dos casos, foi a lesão de membros. Em 175 pacientes a técnica foi o bypass (119 venosos e 56 com próteses ). 206 pacientes receberam ressecção e anastomose término-terminal e 36 pacientes foram tratados com ligadura de tipo primário. Como métodos endovasculares, foram colocadas 5 endopróteses por ruptura traumática de Aorta torácica, 3 stents periféricos, e realizou-se um reimplante de mão. Resultados: A mortalidade global foi de 7,8 % (37 pacientes), na maioria dos casos devido ao politrauma, síndrome de Cushing, SIRS (síndrome da resposta inflamatória sistêmica), e/ou choque séptico. Quanto aos pacientes com RTAT, um deles apresentou óbito por falha do material. 9,1 % dos pacientes sofreram amputação de membro (38 pacientes), dos quais 9 foram por arrancamento de membro, 11 amputações primárias e 18 secundárias. Do total de pacientes que apresentaram lesões vasculares de membros, 60 (5,8 %) receberam fasciotomia pré, intra ou pós revascularização. Conclusões: Nossa aceitável ...

Background: The increase of the urban violence due to the use of fire and white weapons in common crimes as well as the accidents because of the excess of speed without the corresponding safe security measures have produced an increase in the incidence of the vascular traumas, being the most important cause of death in young patients. Objective: To show casuisty and experience in the management of the vascular trauama as well as its resolution. Design: Descriptive and retrospective analyses during the last 10 years. Material and Method: 470 patients were treated from January 1, 2000 up to December 2009. The demographic composition, the lesional mechanism, the affected area and the surgical technique were analysed. The 86.6% were male and the 13.4% female. The average age was 26.9%. The 69.5% have presented penetrant trauma and the 30.5% blunt trauma. The 4.5% have presented injuries on the neck, 12% thoracic ones, 14.9% abdominal ones and our greatest casuistic was the injueries on the arms. In 175 patients the technique was the bypass (119 venous and 56 prothetic ones). 206 patients have received resection and termino-terminal anastomosis and 36 patients were treated with primary binding. As endovascular methods, 5 stents for traumatic rupture of thoracic aorta, 3 peripheral stents and a hand reimplantation were used. Results: The global mortality was of the 7.8% 37 patients), in most of the cases due to the poly-trauma, Crush syndrome, SIRS, and/or septic shock. Regarding to the patients with RTAT, on of them, death has been presented due to material failure. The 9.1% of the patients have suffered from amputation of the member (38 patients), from whom 9 of them were for pulling member, 11 for primary amputations and 18 secondary ones. From the total of the patients that have presented vascular injuries of the members, 60 (5.8%) have received fasciotomy pre, intra or post revascularization. Conclusions: Our acceptable mortality depends on the quickness and ...
