Purpose. To evaluate and implement an ultrasound study with contrast enhancement to diagnose the functioning of the venous anastomosis in women, after surgical treatment for varicose pelvic disease.

Material and methods. An ultrasound study with contrast enhancement of 8 gonad-iliac venous anastomoses in women with varicose veins of the pelvis caused by aorto-mesenteric compression of the left renal vein (Nutcracker syndrome) is presented. And one ovarian vein in an unoperated woman with aorto-mesenteric compression. The «Sonovue» echo-contrast preparation was used, which contrasted exclusively with the vessels.

Results. A qualitative assessment of the images was carried out — the patency of the anastomosis and the quantitative assessment were evaluated — the time of the beginning of the accumulation of contrast and the time to the period of the maximum intensity of accumulation of the drug were determined. The anastomoses we studied and the ovarian vein began to accumulate the drug from 31-40 seconds. The period of maximum intensity of drug accumulation (time-to-peak) of the anastomosis averaged 42.80 seconds, of the ovarian vein - 76.61 seconds.

Discussion. Due to the properties of the contrasting drug to fill the lumen of only the vessel, CEUS proved the functioning of the anastomosis, which was poorly located during a conventional ultrasound examination. Venous anastomosis improves venous outflow from the left renal vein, since the peak of contrast is achieved faster than in the ovarian vein, this indicates that venous hypertension is reduced, and the goal of surgery is achieved.

Conclusion. An ultrasound study with contrast enhancement is a method that allows determining the functioning of the venous anastomosis without radiation exposure, conducting dynamic monitoring and evaluating its work in the early and late stages after surgical treatment.
