ABSTRACT
BACKGROUND: The lack of the great saphenous vein (GSV) in its compartment is rarely mentioned in literature, although it happens in individuals with or without insufficiency of it. With the help of the B-mode ultrasound examination this vein can be easily identified. The aim of this study was to propose a classification for the findings. METHODS: Prospective study carried out for a period of 6 months in a sample of 2,665 lower limbs with ages ranging from 17 to 85, being that 1,286 patients are female. These patients underwent B-mode ultrasound examination as recommended by the literature. This evaluation determined whether there was a GSV aplasia by the analysis of its location in the saphenous compartment. RESULTS: After images were taken they were classified as: type I-aplasia only along the thigh, type II-aplasia only along the calf, type III-aplasia in the distal section of the thigh and proximal calf, type IV-vein in the saphenous compartment in the thigh and aplasia in the whole calf, type V-vein in the saphenous compartment only in a short segment in the proximal thigh, and type VI-vein with short segment in the saphenous compartment in the distal calf. From the total of 2,665 limbs, aplasia was found in 442 (16.6%). CONCLUSIONS: These anatomic findings attain an important role in daily practice, influencing the surgical decision, particularly with the arrival of endovascular procedures, such as the use of laser and thermoablation.

A união entre dentes naturais e implantes osseointegrados para reabilitar pacientes parcialmente edêntulos é um assunto muito controverso, devido às suas diferenças biomecânicas sob cargas oclusais. Possíveis falhas mecânicas e o fenômeno da intrusão dentária têm desencorajado muitos profissionais a fazerem essa união. Contudo, vários desenhos de prótese, relacionando diferentes sistemas de fixação e conexão, têm sido propostos para sanar tais problemas. O presente artigo relata um caso de união dente-implante para reabilitar uma paciente Classe I de Kennedy superior e inferior, e fornecer maior estabilidade e melhor prognóstico às próteses metalocerâmicas instaladas. Em quatro anos de controle, nenhum problema biomecânico ou estérico foi observado
