3. Femoral vein Femoral canal (medial compartment of femoral sheath) Lateral Medial Dr. Sherif Fahmy Middle compartment of femoral sheath
4. Tributaries of Femoral Vein 1- Great saphenous vein. 2- Deep external pudendal vein. 3- Profunda femoris vein. 4- Lateral circumflex femoral vein. 5- Medial circumflex femoral vein N.B. Superficial inguinal veins drain into great saphenous vein. Dr. Sherif Fahmy
5. Femoral vein 1-Profunda femoris vein 2-Lateral circumflex femoral vein 3-Medial circumflex femoral vein 4- Deep external pudendal vein 5-Great saphenous vein Superficial external pudendal vein Superficial epigastric vein Superficial circumflex iliac Dr. Sherif Fahmy
6. Clinical point related to femoral vein: (Page 86) ➢Long catheter is inserted into the femoral vein in the femoral triangle to visualize right side of the heart (Heart angiography).
7. Femoral Sheath (Page 63)
8. Lateral Medial Fascia transversalis Fascia iliaca Dr. Sherif Fahmy Formation of femoral sheath 3 – 4 cm Two anteroposterior septa
9. Lateral compartment (contains femoral artery and femoral branch of genito-femoral nerve) Middle compartment (contains femoral vein) Medial compartment (femoral canal- contains lymph node, lymph vessel and fat) Compartments & Relations of Femoral Sheath Dr. Sherif Fahmy Fascia lata Inguinal ligament Lateral margin of saphenous opening Medial margin of saphenous opening Pectineus muscle
10. Femoral sheath is a downwards prolongation of deep fascia from abdomen around upper 4 cm of femoral vessels. Shape: Funnel shape. Walls: It has: Anterior wall: extends from fascia transversalis. Posterior wall: Extends from fascia iliaca. Relations: Anterior: Saphenous opening covered by cribriform fascia and fascia lata. Posterior: Pectineus muscle. Function of femoral sheath: It protects the upper parts of femoral vessels from friction with inguinal ligament. Dr. Sherif Fahmy
11. Compartments: 1- Lateral compartment: that contains femoral artery and femoral branch of genito-femoral nerve. 2- Middle compartment: that contains femoral vein. 3- Medial compartment (femoral canal): that contains lymph node, lymph vessels and fat.

17. Course of Femoral Nerve
18. L1 L2 L3 L4 Femoral n. L5 Dr. Sherif Fahmy
19. Femoral n. Dr. Sherif Fahmy Psoas major m. Iliacus Inguinal ligament
20. Femoral nerve Psoas major Iliacus m. Femoral vessels inside femoral sheath Inguinal ligament
21. It ends 2 cm below inguinal ligament giving multiple branches Femoral nerve Dr. Sherif Fahmy
22. Branches of Femoral Nerve Muscular: -To iliacus, pectineus, sartorius and quadriceps femoris muscles. Cutaneous: -Medial & intermediate cutaneous nerves of thigh. -Saphenous nerve. Articular: -Hip and knee joints (through muscular branches to quadriceps femoris muscle).
23. Medial cut.n. of thigh Saphenous nerve Femoral n. Dr. Sherif Fahmy
24. Saphenous Nerve (Page 74)
25. Sartorius m. Saphenous nerve Femoral n. Dr. Sherif Fahmy Gracilis m.
26. Lateral Cutaneous Nerve of Thigh
27. Lateral cutaneous nerve of thigh
28. Nerve Injury of Femoral Nerve
29. Nerve Injury of Any Nerve Muscle (motor) loss: name the paralyzed muscles. Sensory loss: describe the area of loss of sensation. Disability: describe the lost actions. Deformity: Fixed deformed position of the paralyzed part. Late wasting changes: Decrease the size of paralyzed part.
30. Nerve Injury of Femoral Nerve Motor loss: paralysis of iliacus, pectineus, sartorius and quadriceps muscles. Sensory loss: loss of sensation at medial side & front of thigh, medial side of leg & foot till the root of big toe. Disability: Inability to extends the knee against resistance (Extension by ilio-tibial tract could be done) and weak flexion of hip. Deformity: Flexed knee and extended hip. Late wasting changes: decrease the size of the front of thigh. Dr. Sherif Fahmy
31. Veins of the Lower Limb (Page 83)
32. A- Superficial Veins 1- Great (long) saphenous vein. 2- Short (small) saphenous vein.
33. Dorsal venous arch Great saphenous vein Saphenous nerve Saphenous openinng Patella Medial malleolus Dorsal digital vein of big toe Dr. Sherif Fahmy
34. Short sphenous vein Sural nerve Popliteal vein Lateral end of dorsal venous arch Lateral malleolus
35. Applied Anatomy • Varicose veins: Dilated veins below damaged valves. • Coronary bypass operation: insertion of a graft from great saphenous vein before and after blocked part of a coronary artery. • Venous cut down: surgical opening over the vein to give blood or fluif transfusion in emergency cases.
