METHOD FOR HEMOSTASIS IN BLEEDING FROM AN UNRESECTABLE RECTAL TUMOR Russian patent published in 2022 - IPC A61M25/01 A61K31/513 A61K31/7004 A61P35/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to interventional radiology. Selective catheterization of the inferior mesenteric artery is performed and recurrent arterioportography is performed with an assessment of angioarchitectonics, determination of the localization of the rectal tumor and search for the source of bleeding. Then superselective catheterization of the superior rectal artery is performed using a hydrophilic catheter and a conductor. After that, superselective embolization of the branches of the upper rectal artery supplying blood to the rectal tumor is carried out according to the “sandwich” method using polymer saturated microspheres “Sphere-Spectrum” with a diameter of 300-500 microns and metal spirals with polymer pile. At the same time, 50 mg of oxaliplatin on a 5% glucose solution is used as a chemotherapeutic drug for saturation, and embolization with microspheres is performed until the blood flow in the branches of the upper rectal artery stops. After that, metal spirals with polymer pile are implanted into the trunk of the upper rectal artery.

EFFECT: method avoids palliative surgical interventions, is a minimally invasive method for stopping bleeding from unresectable tumors of the rectum and is accompanied by a minimum number of complications.
