ABSTRACT
OBJECTIVE:
To analyze anatomy data of popliteal veins (PV), with the purpose of selection of popliteal venous valves construction segment via venography, and to evaluate the surgical results.METHODS:
From February 1998 to November 2010, after analyzing the popliteal vessel anatomy data of 39 limbs and related phlebography research of 862 cases, 102 patients (69 male and 33 female patients, aged from 48 to 71 years, mean 59 years) with severe deep venous insufficiency were selected for popliteal venous valve construction procedures. Doppler ultrasound, continuous dynamic venography, and intraoperative venous pressure measurements were used to assess the hemodynamic changes pre- and postoperatively. Venous clinical severity score (VCSS) were used to evaluate long-term results of deep venous valve construction procedures.RESULT:
In the 102 patients, 93.7% patients had one pair of valves in popliteal vein (PV), locating in the distal 1/3 segment of PV, with gastrocnemius veins (GV) joining with PV above PV valves. Postoperative blood flow volume of the PV was significantly higher than the preoperative volume (732.3 ml/min vs. 150.2 ml/min, t = 8.979, P < 0.001). The proximal pressure was significantly lower than the distal pressure ((12 ± 3) cm H(2)O vs. (15 ± 3) cm H(2)O, 1 cm H(2)O = 0.098 kPa, t = 8.049, P < 0.001). VCSS score was significantly lower after the surgery ((34 ± 15) cm H(2)O vs. (41 ± 14) cm H(2)O, t = 59.780, P < 0.001). Pre- and postoperative hemodynamic changes and VCSS scores were statistically significant (9.3 ± 1.9 vs. 1.8 ± 1.0, t = 59.780, P < 0.001). Mean follow-up were 8.9 years with an ulcer recovery rate of 96.3%, and a 3.7% ulcer recurrent rate.CONCLUSIONS:
Popliteal vessel anatomy study and venography research provide critical information for the PV valve construction part selection, which stayed proximal to the communications of GV and PV. Restoration of gastrocnemius pump function and satisfactory long-term efficacy are received after valve construction.
