Anastomotic veins
These are the veins interlinking the two saphenous veins.

In the legs:
o 3 oblique branches on the medial side
o 4 transversal branches on the external side

In the crural zone:
o Giacomini's vein arises in the external saphenous arch, rising and ending in the
upper 1/3 of the medial saphenous vein
o The external femoral poplitic vein rises on the posterior side of the thigh as far
as the fold in the buttocks.
The Venules of the Poplitea Fossal
They originate from an anastomosis with crural veins or a posterior crural perforator, and
ending in various ways in the external saphenous vein, the gemellary veins, the peroneal vein
or the reticulum of the calf.
The Perforating Veins
Anastomoses between the deep and superficial network with perforation of a fascia. There are
two types:
1. direct - linking directly the saphenous veins to the deep network.
2. indirect - linking the two networks through intermediate trunks, general small in calibre.
They vary widely from one individual to another. They are very numerous:
- in the feet: 50 to 70 in general with valves
- in the legs: retro-tibial: Cockett (2 to 4) and Boyd (2 to 5), muscular: solear (3) - gemellary (5
to 6) - perforating the popliteal fossa
- In the crural zone: Hunter's (or Dodd's) perforator - perforators of the deep femoral vein and
the femoral vein (with an accessory arch)

3.2.3. The Deep Veinous System

90% of the blood uses this return route. The deep veins have valves.

The leg veins contain a large number (10)

The popliteal vein from 0 to 4

The superficial femoral and common vein from 2 to 6

The deep femoral vein 3

The iliac veins rarely have valves.
In the legs the veins are satellites of the arteries of the same name. In principle, there are two
veins for one artery.
The anterior tibial veins: these begin at the back of the foot from the confluence of the deep
dorsal metatarsal veins. They traverse the medial part of the anterior face of the ankle and rise
