21. A common indicator for the prescription of such stockings is chronic peripheral venous insufficiency, caused by incompetent perforator veins. 22. When direct perforators are not included, surgeons can focus on the anatomy of the perforator and the source vessel. 23. Flexing the toes and feet and extending on tiptoes, can all be very useful in detecting perforator vein incompetence. 24. It is necessary to make a self-orientation perforator ( a particularly important issue of orientation in horizontal wells ). 25. For example, a perforator that only traverses through the septum to supply the underlying skin is called a septal perforator. 26. For example, a perforator that only traverses through the septum to supply the underlying skin is called a septal perforator . 27. "" A perforator flap should be named after the nutrient artery or vessels and not after the underlying muscle. 28. If a perforator valve is incompetent then a reflux from the deep to the superficial through the perforator vein will be registered. 29. If a perforator valve is incompetent then a reflux from the deep to the superficial through the perforator vein will be registered. 30. Whereas a flap that is vascularised by a perforator traversing only through muscle to supply the underlying skin is called a muscle perforator.
