OBJECTIVE

To determine the variants of topography and quantity of extraorganic anastomoses of inferior vesical artery (IVA).

MATERIAL AND METHODS

The study included 186 corpses of males (age 22—82 years) and 109 females (age 32—93 years). All people died from accidental causes not associated with pelvic organ diseases. Dissection, vascular injection and statistical analysis were performed.

RESULTS

IVA forms anastomoses with other branches of internal iliac artery in 11.3% of cases on the right and in 12.4% of cases on the left in males. These collaterals in females are noted in 9.2% of cases on the right and in 7.3% of cases on the left. Mean length of extraorganic anastomoses of a. vesicalis inferior in males is 1.4 cm, mean diameter — 1.7 mm. Mean length of such collaterals in females is 1.7 cm, mean diameter — 1.7 mm. Extraorganic anastomoses are more common in proximal and middle thirds of IVA, rarely — in distal third. Linear correlation between diameters of a. vesicalis inferior and its extraorganic anastomoses was not detected in females but found in males.

CONCLUSION

Extraorganic anastomoses of IVA are characterized by certain pattern of origination in males and in females.
