The dorsal venous network of the hand arises from the unification of the dorsal metacarpal and dorsal digital veins. Course The dorsal anastomosis forms an asymmetrical dorsal network and, in 70% of individuals, forms a dorsal arch (Tubbs et al., 2016).
Jan 21, 2018 · A part of the human cardiovascular system, the dorsal venous arch of the hand is included in the superficial venous system. It is a set of connections of veins formed by the union of the...
Nov 28, 2022 · The dorsal metacarpal veins empty into the radial veins and/or the dorsal venous network over the metacarpus. The superficial and deep venous palmar arches accompany their arterial counterparts and function to drain the palmar regions of the hand.

The dorsal venous network of the hand is a venous network on the dorsum (backside) of hand. It is formed by the dorsal metacarpal veins, a dorsal digital vein from the radial side of the index finger and one from the ulnar side of the little finger, and both dorsal digital veins of the thumb.

Superficial venous drainage is primarily performed by the great (long) as well as small (short) saphenous veins. 10 dorsal digital veins originate through sides of the toes. Surrounding 8 veins merge at the web of the toes creating 4 dorsal metatarsal veins. They merge and create dorsal venous arch, being located opposite the middle of the dorsum o...
Small saphenous vein: drains blood via the lateral dorsal venous arch along with posterior leg (calf) within the popliteal vein posterior towards the knee.Great saphenous vein: drains blood via the medial dorsal venous arch, leg, as well as thigh within the femoral vein just inferior towards the inguinal ligament.The arch helps in draining oxygen-depleted blood through the foot. Also, it gets blood via the dorsal metatarsal veins, which drains the foot’s metatarsal area and also drains the dorsal digital veins supplying the toes. From here, the arch drains its oxygen-depleted blood within the small as well as large saphenous veins. Consequently, the blood f...

Definition. On the dorsum of the foot the dorsal digital veins receive, in the clefts between the toes, the intercapitular veins from the plantar cutaneous venous arch and join to form short common digital veins which unite across the distal ends of the metatarsal bones in a dorsal venous arch. Proximal to this arch is an irregular venous net ...
In 1968, Kuster et al provided the most complete description of the veins of the foot, 1 describing five systems: (i) the superficial veins of the sole (also known as Lejars’ venous plexus) 2; (ii) the deep veins of the sole; (iii) the superficial dorsal plexus; (iv) the marginal veins and dorsal venous arch; and (v) the perforating system. i.
