ABSTRACT
INTRODUCTION: The great saphenous vein is widely used as a graft in coronary artery bypass grafting surgery. Complications due to saphenous vein harvesting can be minimized when using ultrasonography mapping and marking. OBJECTIVE: To analyze by clinical trial the use of vascular ultrasonography to map the saphenous vein in coronary artery bypass grafting to determine viability and dissection site. METHODS: A total of 151 consecutive patients submitted to coronary artery bypass surgery with the use of the great saphenous vein as a graft were selected for this prospective study. They were divided into two groups: Group 1 - 84 patients were submitted to ultrasonographic mapping and marking of the saphenous vein; Group 2 - 67 patients had saphenous vein harvested without any previous study. Both groups were coupled with follow-up on the 1st, 5th and 30th postoperative days. Primary endpoints were need for incision of the contralateral leg and wound complications within 30 days. RESULTS: Both legs had to be incised in 6 (8.95%) patients from Group 2 (P=0.0067). Wound complications occurred in 33 (23.4%) patients within 30 days, 21 (35%) from Group 2 e 12 (14.8%) from Group 1 (OR 3.095, 1.375-6.944, CI 95%, P=0.008). Within 30 days there were 4 (2.8%) deaths, all in Group 2 (P=0.036). CONCLUSION: The use of vascular ultrasonography for mapping of the great saphenous vein in coronary artery bypass surgery has properly identified and evaluated the saphenous vein, significantly reducing wound complications and unnecessary incisions. It would be advisable to use this noninvasive and easy to use method routinely in coronary artery bypass surgery.

O uso da biópsia de próstata aumentou significativamente com a utilização doteste de PSA para câncer de próstata (CaP). A biópsia transretal da próstata é geralmente considerada um procedimento seguro, mas existem complicações associadas com a técnica. É o Câncer o mais comum do homem brasileiro. Objetivos: traçar o perfil institucional dos pacientes submetidos à biópsia de próstata. Analisar as complicações do procedimento de biópsia. Resultados: das complicações analisadas os eventos hemorrágicos foram os mais freqüentes, 95,7% do total de complicações. O volume prostático ao USG teve média de 47,1cm3, ao toque retal obteve-se média de 40g, ambos sem relação estatisticamente significativa com complicações do procedimento diagnóstico. Foi utilizado o teste de qui-quadrado nos cálculos estatísticos com valor de significância menor ou igual a 0,05. Conclusão: complicações pós-biópsia da próstata foram em sua maioria auto-limitada e não requerem intervenção médica. A taxa de complicações graves foi baixa e, portanto, biópsia transretal de próstata guiada por ultra-sonografia é um procedimento seguro e eficaz
