Abstract
A method for surgical correction of vascular occlusions involving replacement of the affected portion of the vessel with a vascular autotransplant grown in the patient's tissues around the modelled preform from a magnetic alloy which speeds up killing, reduces the risk of thromboses, infection and rejection and forestalls the development of the destructive processes in the wall of the autotransplant.
Claims2
A method for surgical correction of vascular occlusions comprising:
- determining the affected portion of the vessel;
- modelling and making a magnetic alloy preform corresponding in shape and size to said affected portion of the vessel;
- embedding said preform into the subcutaneous fat of the patient for 21-29 days until it becomes overgrown with a 3-layer biological capsule;
- exposing said biological capsule from the surrounding tissues;
- removing said preform from said biological capsule to produce an autotransplant;
- cutting out a fragment from said autotransplant, corresponding in shape and size to said affected portion of the vessel;
- resecting said affected portion of the vessel;
- stitching up said cut-out fragment of the autotransplant in place of the resected portion of the vessel.
