“…The superficial veins respond to increased pressure by dilating to accommodate the increased blood flow. Valvular incompetence occurs and varicosities appear 21 . In addition, with movement of the lower limbs, the high venous pressure that normally occurs within the calf is transmitted straight to the superficial veins and subcutaneous tissues drained by these communicating veins 22,23 .…”

The venous anatomy of the leg is described with special reference to the superficial venous system. The histologic and histochemical differences between varicose and normal veins are presented. The pathophysiology of varicose veins is related to congential or acquired abnormalities of the deep venous system, venous valves, and/or fascial or vein wall weakness. Increased deep venous pressure may be both proximal and distal in etiology, arising from arteriovenous anastomoses, incompetent communicating veins, or venous obstruction. Primary valvular incompetence arises from venous obstruction (thrombosis), thrombophlebitis, or valvular agenesis. Secondary valvular incompetence occurs from deep venous obstruction or increased venous distensibility (usually secondary to circulating estrogens). Finally, fascial weakness of the vein wall or supporting fascia provided a genetic basis for the pathophysiology of varicose veins. Understanding the anatomy and pathophysiology of varicose veins should lead to a more rational and efficacious treatment.

“…Typically, irregular thickening of the media with myocytes occurs in both types of vessels. It can be inferred that increased intraluminal pressure causes vein dilatation 4 and subsequent thickening of the vein wall. Venous dilatation also results in valvular incompetence, which in turn leads to flow reversal in the superficial venous system and extension of the venous hypertension to more distal vessels.…”

The records of 305 consecutive patients who had presented with cosmetic symptoms related to varicose and/or spider veins over a 12-month period were studied. Following clinical assessment, 250 (82%) patients were referred for duplex venous imaging. A total of 500 lower limbs were evaluated; 236 (47%) were documented to have incompetence in the superficial venous system (long or short saphenous veins). Only 6 (1%) limbs had deep venous incompetence and 45 (9%) limbs were found to have perforator incompetence. Short saphenous vein incompetence was found in 59 (12%) limbs. In the long saphenous vein there was a consistent pattern of an increasing incidence of incompetence from the saphenofemoral junction down to the below-knee segment. The duplex imaging findings were applied to determine the optimal treatment, ie, whether surgery, sclerotherapy, or a combination of both would provide the best short- and long-term results. The possible etiology and pathophysiology of spider and varicose veins are discussed in relation to these results.
