ABSTRACT

Background: In vein anatomy teaching, cadaver dissections were displaced by phlebography, ultrasound, Doppler duplex, computerized phlebotomography and even magnetic angioresonance. Excellent drawings have been in use but the observation of veins during a dissection is very useful.
Objective: To communicate the experience obtained at the Forensic Service of Tijuana while performing oriented vein demonstrations and interrupting the perforators of the legs.
Methods: Infrarenal cava vein and its branches were observed for anomalies, compression or other alteration. Obstruction of the iliac veins by a distended bladder was investigated. In 10 extremities silicon was injected into the external iliac vein to demonstrate the presence of valves. From the groin to the foot veins were dissected to see their relation with arteries and nerves and appreciate the risk of injury during surgical excision. After transendoscopically clipping the perforator veins, they were divided.
Results: We could evaluate areas of compression in the cava vein or its branches. A distended urinary bladder may compress the iliac veins. In 8 of 10 instances silicon injection in the iliac veins demonstrated healthy valves. We could consider the risks of veins anatomical variations. Subfacial endoscopic clipping and section of leg perforators was safely accomplished.
Conclusions: Fresh cadaver dissection of veins is a useful tool in venous anatomy and pathology teaching.
