Objective: To investigate the incidence of lower limb venous insufficiency
in morbidly obese patients.
Patients and methods: The study group comprised 125 patients (109 women, 16
men). The median (range) age and body mass index were 35 (19-59) years and
42 (32-68) kg/m(2) respectively. Eleven patients had clinical signs of var
icose veins or had previously undergone varicose vein surgery. Patients wer
e investigated with duplex ultrasound scanning on the day before surgery. I
liac, femoral, popliteal, and long and short saphenous veins in both legs w
ere studied.
Results: A total of 33 patients had abnormal reflux in the superficial vein
s (>0.5 s). In the deep veins 2 patients had valvular incompetence in the c
ommon femoral vein with reflux times of 2 and 0.7 s respectively. At reinve
stigation 18 and 24 months after surgery the reflux times were normalised.
Conclusion: In this study the incidence of deep venous incompetence in the
lower limb in morbidly obese patients is low.
