RESUMO
INTRODUCTION: The incidence of vascular injury associated with knee arthroplasty is scarce, but, when they occur, the consequences are serious. OBJECTIVES: Describe the incidence of vascular lesions in our center and evaluate time to diagnosis, resolution and follow-up. MATERIALS AND METHODS: Retrospective cohort during the 2010-2019 period of primary arthroplasties and knee revision. The incidence of vascular lesions and their demographic characteristics were analyzed. Type of lesion, diagnostic method and treatment were recorded. It was evaluated in distant follow-up of pain and functionality. RESULTS: 7.940 primary total knee arthroplasty and revision surgeries were recorded, and a report of 7 emergency cases for vascular lesions was also recorded, with an incidence of 0.088%. 3 vascular lesions were caused by direct laceration of the popliteal artery, 1 case of thrombosis of the popliteal artery and 3 cases of pseudoaneurysmal lesion of the superior genicular artery. Three vascular lesions that occurred in primary arthroplasty were immediately repaired by a vascular surgeon. Pseudoaneurysm lesions and thrombosis were resolved by angiographic procedure. DISCUSSION: Vascular complications around the knee are rare. Time to diagnosis and treatment is essential. Digital angiography is a diagnostic and therapeutic tool. There are various repair techniques, whether it's embolization, cauterization, stenting or endoprosthesis; therefore, digital angiography is a safe method with a low complication rate. CONCLUSION: The incidence of vascular lesions in knee arthroplasty in our center is very low. The cases were diagnosed and resolved early, without registering subsequent complications with good functional results in distant follow-up.

The parameters of the trichogram of the pubic hair were studied with a previously described technique. Measurements were made on males and on non-pregnant, pregnant and post-partum females. In males and non-pregnant females denisty and rate of growth steadily decrease with age. There was a higher percentage of telogens in women. Hair thickness was not modified. The most important findings are related to pregnancy and post-partum which did not induce any change in the parameters of the trichogram of the public area. These findings indicate a behaviour of the pubic hair different from the scalp and axillary hair.

En los últimos años, ha sido ampliamente difundida la utilización de los ultrasonidos, para el diagnóstico de las lesiones del sistema muscular y tendinoso. Creemos que la utilidad mayor de la ecografía muscular, radica en el diagnóstico de pequeñas lesiones, en donde la clínica no es tan precisa. Siendo un método operador dependiente, se torna imprescindible reconocer la importancia de la disposición de los elementos ecorrefringentes, base fundamental del estudio, para descartar áreas hipoecogénicas, que son interpretadas erróneamente como lesiones. En base a nuestra propia experiencia, damos algunas pautas para considerar estos factores de error
