RESUMO
BACKGROUND: Lower limb amputations represent a high social, economic and health burden. Most of them are preventable and reflect areas for improvement in health care, making it essential to know their epidemiology. MATERIALS AND METHODS: This is a retrospective population-based cross-sectional analysis on all lower limb amputations performed in public hospitals in Sao Paulo between 2009 and 2020, the most populous Brazilian state, with 46 million inhabitants. Using a public database, we evaluated types, rates and trends of the amputations performed, main etiologies leading to the indication for amputation, hospital length of stay and in-hospital mortality rates, demographics of the amputees and procedure costs. RESULTS: In total, 180,595 lower limb amputations and surgical revision of amputations were performed, with toe amputations (45%) and major amputations (33%) being the most frequent types of surgeries, with a recent significant increase in the rates for both these procedures. Peripheral artery disease was the most frequent etiology, followed by diabetes mellitus, with both showing an upward trend over the years. Most patients were male (69.3%), Caucasians (55.6%) and elderly. August was the month with the highest number of amputations in all years. Overall in-hospital mortality after lower limb amputations was 6.6%. Total reimbursed by the government was US$ 67,675,875.55. CONCLUSIONS: Peripheral artery disease is the most frequent underlying diagnosis for lower limb amputations, followed by diabetes mellitus, with both showing an upward trend over the years. We observed seasonality in procedure rates, with peaks in August in all years.

A total of 85 consecutive patients had their wound area measured. The procedure was executed in two parts. The first was to take photographs of the wound using a smartphone and measure the area using the imitoMeasure application (imito; imito AG, Zurich, Switzerland) by two raters. The second was to take photographs of the same wound using a 10-megapixel digital camera and posterior measurement of the area using ImageJ software (National Institutes of Health, Bethesda, Md) by one operator. The mean area of the wounds was 12.20 ± 10.45 cm2 for imito and 12.67 ± 10.86 cm2 for ImageJ measurement. The interclass correlation coefficient (ICC) between ImageJ and imito was 0.978 for a single measure and 0.989 for the average measure. Considering the two measurements, the ICC demonstrated excellent interobserver correlation using imito (0.987). Larger wounds had a greater difference between the methods (4.28% greater with the ImageJ measurement when considering areas >9 cm2). No difference was found between iOS (ICC, 0.995) and android (ICC, 0.970) smartphone operating systems. The smartphone application is a useful method for area measurement with excellent accuracy compared with digital photography and the ImageJ processing tool.
RESUMO

Rubber projectiles are used as an alternative to metal bullets owing to their lower morbidity and mortality rate. There are few reports of vascular lesions of extremities caused by rubber projectiles in the literature. The authors report the case of a 37-year-old man who was the victim of a penetrating injury to the left thigh with a rubber projectile. He reported only pain at the site of the injury; pulses were decreased in the affected limb. After arteriography confirmed an injury to the superficial femoral artery, he underwent an arterial and venous femorofemoral bypass using a reversed contralateral saphenous vein.
RESUMO
BACKGROUND: The endovascular management of arterial injuries has resulted in reduced operating time, blood loss, hospital mortality, lower incidence of sepsis, and decrease in mortality rates. For penetrating trauma, however, the benefits of endovascular therapy are questionable. PATIENTS AND METHODS: Data were obtained by retrospective analysis of electronic medical records. All patients with vascular trauma seeking care at our institution from January 2010 to December 2015 were reviewed. A total of 223 vascular trauma patients were enrolled. Of these, 18 patients (8 %) were treated with endovascular techniques. The data related to clinical presentation, patient characteristics, technical aspects of the treatment, and follow-up were analysed. RESULTS: The mean patient age was 35.4 ± 17.8 years, 94 % were male. The mean injury severity score was 10.4 ± 2.5. The most commonly observed trauma mechanism was a gunshot in 10 cases (55 %), followed by lesions provoked by arterial catheter misplacement in five cases (27 %), and stab wounds in three cases (16.6 %). The main injury site was the subclavian artery, accounting for eight cases (44 %), followed by the superficial femoral artery and the tibiofibular trunk in two cases, respectively (18 %). The anterior tibial, fibular artery, axillary, common carotid, superior mesenteric, and profunda femoris were each affected once. Arteriovenous fistula was detected in nine cases (50 %), pseudoaneurysms in nine cases (50 %), and short occlusion in two cases (11 %). The mean follow-up duration was 753 days. The primary patency rate was 92.3 and 61.5 % after one and two years, respectively. The survival rate was 94.4 % after one and two years. Infection of the stents or limb amputations were not identified at follow-up. CONCLUSIONS: The endovascular treatment of penetrating arterial injuries with covered stents is feasible. However, the criteria used to choose the best method must be individualized.

Contexto: A terapia endovascular tem avançado muito como tratamento para a doença arterial oclusiva infrainguinal, principalmente com o desenvolvimento dos materiais e dos stents autoexpansíveis de nitinol. Objetivo: Avaliar os resultados e os fatores determinantes da angioplastia fêmoro-poplítea em pacientes portadores de isquemia de membros inferiores. Métodos: Foram tratados, através de angioplastia com ou sem stent, 114 pacientes, e acompanhados por um período médio de 12 meses. A média de idade foi de 66 anos; 53 por cento eram do sexo feminino; 23,7 por cento eram portadores de claudicação incapacitante; 8,8 por cento, de dor isquêmica de repouso; e 67,5 por cento, de lesão trófica. As lesões foram classificadas segundo o TransAtlantic Inter-Society Consensus II em A (53 por cento), B (34 por cento), C (5 por cento) e D (9 por cento). Resultados: A análise angiográfica do leito distal mostrou uma média de 1,4±1,0 artérias infrapoplíteas pérvias. O sucesso inicial foi de 97 por cento. No seguimento de 1, 6, 12 e 24 meses, a perviedade primária foi de 94, 78, 48 e 31 por cento, e a primária assistida, de 94, 84, 73 e 61 por cento, respectivamente (p = 0,005). O leito distal pobre e a presença de diabetes melito foram associados a uma menor perviedade primária (p = 0,01), enquanto a extensão da lesão não influenciou os resultados. As taxas de salvamento de membro em 6, 12 e 24 meses foram de 95, 90 e 90 por cento, respectivamente. Conclusões: A extensão das lesões tratadas não foi um fator determinante em nossa casuística para o menor sucesso da angioplastia, o que pode sugerir que as indicações para o tratamento endovascular possam ser ampliadas para pacientes com lesões TransAtlantic Inter-Society Consensus II C/D.
Background: Endovascular techniques have undergone major advances with regard to the treatment of infrainguinal arterial occlusive disease, mainly as a result of development of new devices and self-expanding nitinol stents. Objective: To evaluate the results and determinant factors of femoropopliteal angioplasty in patients with critical lower limb ischemia. Methods: During the study, 114 patients were submitted to angioplasty or stenting and followed during an average of 12 months. Mean age was 66 years, and 53 percent were female; 23.7 percent presented disabling claudication, 8.8 percent ischemic rest pain and 67.5 percent tissue loss. Lesions were classified as A (53 percent), B (34 percent), C (5 percent) and D (9 percent) according to the TransAtlantic Inter-Society Consensus II. Results: Angiographic run-off analysis showed an average of 1.4±1.0 patent infrapopliteal artery. Initial success rate was 97 percent. At 1, 6, 12 and 24 months of the follow-up period, primary patencies of 94, 78, 48 and 31 percent, and assisted primary patencies of 94, 84, 73 and 61 percent were achieved (p = 0.005). Poor run-off and diabetes mellitus were directly associated with lower primary patency rates (p = 0.01), while angiographic severity of the lesions did not influence results. Limb salvage rates calculated at 6, 12 and 24 months were 95, 90 and 90 percent, respectively. Conclusions: Lesion length was not a determinant factor of lower success rates for angioplasty or stenting, which may suggest that indications for endovascular treatment can be extended to patients with TransAtlantic Inter-Society Consensus II C/D lesions.

O implante transhepático de cateteres de diálise de longa permanência é um procedimento de exceção, utilizado para obter um acesso em pacientes com oclusão de veias centrais de membros superiores e inferiores. O caso descrito relata um paciente jovem, com história de 15 anos de diálise, que foi submetido no passado a um transplante renal sem sucesso. Esse paciente encontrava-se em urgência dialítica e oclusão comprovada de veias centrais de membros superiores e de veias ilíacas. Foi realizado o implante do cateter de longa permanência pelo acesso transparietohepático sob anestesia geral. A ponta do cateter foi posicionada ao nível do átrio direito. A diálise foi realizada satisfatoriamente no mesmo dia.
Transhepatic insertion of long-term dialysis catheter is an exception procedure used to obtain access in patients with central vein occlusion of lower and upper limbs. We report on a case of a young patient with history of dialysis for 15 years, who was submitted to an unsuccessful renal transplantation. This patient was in dialytic emergency and had confirmed occlusion of upper limb central veins and iliac veins. Transhepatic insertion of a long-term catheter was performed under general anesthesia. The catheter tip was placed at the level of the right atrium. Dialysis was satisfactorily performed on the same day.
