Correlation of clinical findings with venous hemodynamics in 386 patients with chronic venous insufficiency.
Deep venous insufficiency secondary to deep valvular incompetence predominated over superficial venous insufficiency in an unselected patient population with advanced chronic venous insufficiency. Venous obstruction was uncommon (5 percent), suggesting that venous bypass surgery may have limited applicability in the management of chronic venous insufficiency. Although the majority of patients (72 percent) with stage III venous disease (ulcer) had deep venous insufficiency alone and would be potential candidates for deep valvular reconstruction, 13 percent were found to have superficial venous insufficiency alone, and the remaining 15 percent, deep venous insufficiency with a hemodynamically significant component of superficial venous insufficiency. These findings suggest that not all patients with stage III disease have altered hemodynamics on the basis of deep venous valvular incompetency. Although most stage III chronic venous insufficiency is secondary to altered deep venous hemodynamics, as demonstrated by shortened venous refill time, there is a significant group of patients with severe chronic venous insufficiency having superficial venous insufficiency alone or in combination with deep venous insufficiency (28 percent). Thus, it is imperative that those patients with superficial venous insufficiency be identified by a widely available and reproducible method, such as light reflection rheography, since they may respond to surgery of the superficial venous system alone.
