Quick Overview
What is small saphenous vein? The small saphenous vein (SSV), also known as the lesser saphenous vein. It is a superficial vein of the leg which drains blood from the lateral side of the leg and runs up the posterior surface of the leg to drain into the popliteal vein.

Anatomy Small Saphenous Vein
The SSV is a relatively long and narrow vein. It originates at the lateral marginal vein of the foot and runs up the posterior surface of the leg, between the two heads of the gastrocnemius muscle. It then drains into the popliteal vein at the saphenopopliteal junction.
| Vein | Description |
| Origin | Lateral marginal vein of the foot |
| Branches | Sural vein, Lateral calcaneal vein, Lateral malleolar veins |
| Venous drainage | Popliteal vein |
| Function | Contributes to overall venous circulation |
Location
The SSV is located on the posterior surface of the leg, between the two heads of the gastrocnemius muscle.
Function
The primary function of the Small Saphenous Vein is to facilitate the return of deoxygenated blood from the lower leg and calf muscles to the deeper venous system. By collecting and transporting this blood, the vein contributes to overall venous circulation and helps maintain optimal blood flow in the body.
Branches
The SSV has a number of branches, which include;
- Sural vein: The sural vein is the main branch of the SSV. It drains blood from the lateral side of the calf.
- Lateral calcaneal vein: The lateral calcaneal vein drains blood from the lateral side of the heel.
- Lateral malleolar veins: The lateral malleolar veins drain blood from the lateral side of the ankle.
Venous Drainage
This vein serves as a critical component of the venous drainage system of the lower limb. It collects blood from various veins in the calf and posterior leg region, ensuring that metabolic waste and deoxygenated blood are efficiently transported away from the muscles.
Clinical Importance
The Small Saphenous Vein holds clinical significance in various medical scenarios. It may serve as an access point for venous catheters, allow for blood sampling, or be involved in surgical procedures such as varicose vein treatment.
Conditions Associated with the SSV
A number of conditions can affect the SSV, which include;
- Varicose veins: Varicose veins are enlarged and swollen veins. They can be caused by a number of factors, including weakness in the vein walls and increased pressure in the veins.
- Thrombophlebitis: Thrombophlebitis is a blood clot in a vein. It can cause pain, redness, and swelling in the affected area.
- Phlegmasia alba dolens: Phlegmasia alba dolens is a rare condition that causes severe swelling and pain in the leg. It is caused by a blood clot in the deep veins of the leg.
Prevention of SSV Disorders
There are a number of things you can do to prevent SSV disorders, some of which are;
- Maintaining a healthy weight
- Exercising regularly
- Avoiding standing or sitting for long periods of time
- Wearing compression stockings
- Elevating your legs when resting
Question
1. Small Saphenous Vein drains into?
The Small Saphenous Vein typically drains into the Popliteal Vein, which is a deep vein located in the popliteal fossa behind the knee.
2. Explain Small Saphenous Vein anatomy?
The Small Saphenous Vein is a substantial superficial vein in the lower limb. It runs along the posterior aspect of the calf and lower leg, often originating near the lateral ankle bone (lateral malleolus) and ascending towards the popliteal fossa behind the knee.
3. Explain Small Saphenous Vein thrombosis?
Small Saphenous Vein Thrombosis refers to the formation of blood clots within the Small Saphenous Vein. This condition can lead to pain, swelling, and other symptoms and requires medical evaluation and management.
4. What is meant by Small Saphenous Vein ultrasound?
SSV ultrasound is a diagnostic procedure that uses ultrasound technology to visualize and assess the Small Saphenous Vein. It is commonly used to diagnose conditions like thrombosis or varicose veins in this vein.
5. What is Small Saphenous Vein ablation?
Small Saphenous Vein ablation is a medical procedure used to treat conditions such as varicose veins. It involves the closure or removal of the SSV to redirect blood flow to healthier veins. Various techniques, including laser or radiofrequency ablation, are used to achieve this.
