Overview
Normal Anatomy
The great saphenous vein (GSV) originates from where the dorsal vein of the first digit (the large toe) merges with the dorsal venous arch of the foot.
After passing anterior to the medial malleolus (where it often can be visualized and palpated), it runs up the medial side of the leg. At the knee, it runs over the posterior border of the medial epicondyle of the femur bone.
The great saphenous vein then courses laterally to lie on the anterior surface of the thigh before entering an opening in the fascia lata called the saphenous opening. It joins with the femoral vein in the region of the femoral triangle at the saphenofemoral junction.
The small saphenous vein (also lesser saphenous vein) is originated where the dorsal vein from the fifth digit (smallest toe) merges with the dorsal venous arch of the foot, which attaches to the great saphenous vein. It is considered a superficial vein and is subcutaneous (just under the skin). From its origin, it courses around the lateral aspect of the foot (inferior and posterior to the lateral malleolus) and runs along the posterior aspect of the leg (with the sural nerve), passes between the heads of the gastrocnemius muscle, and drains into the popliteal vein, approximately at or above the level of the knee joint.

Pathological Findings
Saphenous Vein Graft Diseases
Saphenous Vein Graft Aneurysms
It is also known as SVGA, aortocoronary saphenous vein graft aneurysms, saphenous vein graft aneurysm disease and saphenous vein graft aneurysmal dilatation.
Causes of Saphenous Vein Graft Aneurysms
- Atherosclerosis
- Hypertension
- Mycotic
- Postoperative mediastinitis
- Previous aneurysms
- Torn sutures
Saphenous Vein Graft Degeneration
Saphenous Vein Graft Occlusion
Treatment
Thrombolysis
PCI
Plain Old Balloon Angioplasty (POBA)
Bare Metal Stents
Drug Eluting Stents
Excimer Laser Coronary Angioplasty (ELCA) of Saphenous Vein Grafts
At the end of 80's [1], ELCA was introduced and thought to be particularly suitable for saphenous vein grafts that were otherwise difficult to treat with balloon angioplasty alone.[2]
