The document discusses the anatomy and pathophysiology of the venous system in the lower extremities. It describes the deep and superficial venous systems, including the great and small saphenous veins, and the perforating veins that connect them. It explains how the musculovenous pump and one-way valves work to pump blood out of the legs, and how valve dysfunction or reflux can lead to varicose veins. Doppler exams are used to detect normal versus refluxing blood flow.

It is estimated that 20% of American women and 7% of American men suffer from venous disease. Venous disease results in symptoms such as aching, fatigue, swelling, and pain in the legs which can interfere with daily living.Cosmetic issues may affect quality of life. At least 20% of patients with venous disease will develop leg ulcers. This presentation outlines the normal anatomy and physiology of venous drainage of the extremities as well as the common venous disorders such as varicose veins and deep vein thrombosis.

It is a power point presentation by Dr Zobayer Mahmud Khan while he was taking a lecture class of this topic in Sir Salimullah Medical College, Mitford, Dhaka. Here the venous drainage and the lymphatic drainage are stated clearly with many of the clinical events. Hope you can learn from here. Photographs used here are collected from The "Essential of human Anatomy (inferior extremity) by A.K. Datta".

Blood Vessels of Lower Limb.pptx

Blood Vessels of Lower Limb.pptx

Blood Vessels of Lower Limb.pptx

The main artery of the lower limb is the femoral artery. It is a continuation of the external iliac artery (terminal branch of the abdominal aorta). The external iliac becomes the femoral artery when it crosses under the inguinal ligament and enters the femoral triangle. In the femoral triangle, the profunda femoris artery arises from the posterolateral aspect of the femoral artery. It travels posteriorly and distally, giving off three main branches: Perforating branches – Consists of three or four arteries that perforate the adductor magnus, contributing to the supply of the muscles in the medial and posterior thigh. Lateral femoral circumflex artery – Wraps round the anterior, lateral side of the femur, supplying some of the muscles on the lateral aspect of the thigh. Medial femoral circumflex artery – Wraps round the posterior side of the femur, supplying its neck and head. In a fracture of the femoral neck this artery can easily be damaged, and avascular necrosis of the femur head can occur.
