are typically located within a radius of 6 cm from the entrance of the pedicle to the muscle.
veins, that connect the deep and superficial venous networks, play an important role in the initiation and progression of varicose vein dilatation, as the presence of reflux in the perforator
veins leads to increased venous pressure in the superficial venous network, with secondary varicose dilation of superficial veins (9,10).
The flap was harvested on peroneal perforator
vessels marked on the skin (Figure 1).
Among many PVs, the medial calf perforators
are probably the most important [5, 12].
Short LAD runs in the anterior interventricular groove, giving rise to septal perforator
and ends in the proximal anterior interventricular groove.

from the LAD.
Use of Doppler ultrasound may be helpful in identifying the most promising perforator
artery near the defect.
Explaining the procedure, Dr Rezai told Gulf News: "Perforator
flaps such as the DIEP flap are "free" flaps consisting of skin, fatty tissue and tiny blood vessels which are micro-surgically removed from the donor site and transferred to the chest for reconstruction of the new breast.
flaps have revolutionized the practice of modern reconstructive plastic surgery.
as a fasciocutaneous flap based on perforators
of the descending branch of the lateral femoral circumflex artery.
The HDE of the venous circulation was done from higher up in rectum up to the anal verge and included the evaluation of site size and number of RVs, pararectal varices, and perforators
(inflowing or outflowing) at three distances in rectum: 8 to 10 cm, 6 to 8 cm, and 4 to 6 cm.
Rather, it is currently possible to mobilize wide portions of tissue that are pedicled just on perforators
