FIELD: medicine.
SUBSTANCE: diagnostic angiography is performed. The microcatheter tip inserted inserted through the diagnostic catheter is positioned more distally from the discharge of the upper rectal branches artery supplying the sigmoid colon and rectum ampoule. Then, liquid embolizing material, which is a histoacryl and lipiodol mixture at a ratio of one to eight, is introduced using a microcatheter. The microcatheter is pulled proximally. Then angiographic monitoring of embolization effectiveness is performed.
EFFECT: method allows to perform embolization of distal branches of the upper rectal artery supplying hemorrhoids, due to entire artery embolization, development of collateral blood flow is minimized, thereby reducing the risk of hemorrhoids recurrence.
