What are the perforators of lower limb?
The perforating veins of the lower limb (PV or “perforators”) are so called because they perforate the deep fascia of muscles, to connect the superficial venous systems of the lower extremity with the deep veins where they drain. There are numerous veins in variable arrangement, connection, size, and distribution.
What nerves innervate the lower limbs?
Both the lumbar and sacral plexus supply innervation to the lower extremity. The sacral plexus gives rise to the sciatic nerve (L4 through S3), posterior femoral nerve (S1 through S3), superior gluteal nerve (L4 through S2), and inferior gluteal nerve.
Where are perforator veins located?
They exist along the length of the lower limb, in greater number in the leg (anatomical ref to below knee) than in the thigh. Some veins are named after the physician who first described them: Dodd’s perforator at the inferior 1/3 of the thigh.
Where are the veins in the lower leg?
Deep veins, located in the center of the leg near the leg bones, are enclosed by muscle. The iliac, femoral, popliteal and tibial (calf) veins are the deep veins in the legs. Superficial veins are located near the surface of the skin and have very little muscle support. The great saphenous vein is a superficial vein.
How many perforator veins are there?
About 150 perforating veins have been identified, and they are grouped based on their location.
Are perforators normal?
Perforators are normal, but also can lead to trouble in the person with Venous Insufficiency. Perforator veins perforate the deep fascia of muscles, to connect the superficial veins to the deep veins where they drain.
How do you remember the nerves of the lower limbs?
Mnemonic
- I: iliohypogastric nerve.
- I: ilioinguinal nerve.
- G: genitofemoral nerve.
- L: lateral femoral cutaneous nerve.
- O: obturator nerve.
- F: femoral nerve.
- L: lumbosacral trunk.
Is walking good for varicose veins?
Exercise can increase your body’s ability to pump blood up the leg back toward the heart. It also helps keep your weight down, which further decreases your chances of getting varicose veins. Walking is a good choice, as are low-impact activities, such as swimming and biking.
How do you treat a perforator vein?
Minimally invasive treatments have replaced traditional surgical treatments for incompetent perforator veins. Current minimally invasive treatment options include ultrasound guided sclerotherapy (USGS) and endovascular thermal ablation (EVTA) with either laser or radiofrequency energy sources.
Where are incompetent perforators found in the leg?
Incompetent perforators usually are observed at the medial thigh, middle and distal third of the leg, and mid third of the calf. 6,13 Scanning of the lateral aspect of the lower limb also is recommended.
How are perforator veins used in lower limbs?
In this case, lower limbs venous ultrasonography plays an important role in evaluating which continent perforators can be used. However, increasing evidence (see below) is starting to favor the treatment of incompetent perforator veins by minimally invasive techniques such as TRLOP.
How did the perforator flaps of the lower extremity evolve?
While identification of appropriate vasculature was an important step in the evolution of perforator flaps of the lower extremity, flap design has also played a large role in the evolution of these flaps (including the need for vascular territories to be studied).
Where are the distal posterior tibial perforators located?
The most distal posterior tibial perforators (Cockett I) are located behind the medial malleolus, and the middle and upper posterior tibial perforators are located more proximally in the calf (at 7-9 cm and 10-12 cm from the medial malleolus, respectively) and about 2.5 cm medial to the tibia.
