METHOD FOR SURGICAL MANAGEMENT OF HIGH INTERMITTENT CLAUDICATION SYNDROME ACCOMPANYING INTERNAL ILIAC ARTERY OCCLUSION Russian patent published in 2024 - IPC A61B17/11 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to angiology, vascular surgery. Gluteal approach is used to separate the superior gluteal artery (SGA). Posterior approach to a deep femoral artery (DFA) is performed. Superior gluteal artery is bypassed from the ipsilateral deep femoral artery as follows: skin is incised 15 cm long in the middle part of the line connecting the spinous process of the V lumbar vertebra with an apex of the greater trochanter. Upper edge of gluteus maximus muscle is exposed, its own fascia is dissected along it, gluteus maximus muscle is pulled down and medially to lower edge of gluteus medius muscle, which is retracted upwards and laterally. Stem and branches of the SGA are separated and taken on the holders, a vertical incision is made in parallel to the lateral edge of the biceps muscle of thigh, which starts 6 cm higher and continues 10 cm below the gluteal fold, blunt and acute method mobilize lower edge of gluteus maximus muscle and pull up, exposed proximal part of biceps muscle of femur and sciatic nerve are retracted in medial direction. Longitudinal incision of a greater adductor muscle is made along a line of its attachment to a femur; the perforating branches of the DFA passing through this muscle are used as a reference point. DFA is separated from surrounding tissues and taken on holders. Then the operator bluntly creates a tunnel under the gluteus maximus muscle in the direction of the SGA, forms a proximal anastomosis between the vascular shunt with the DFA, the shunt passes through the created tunnel into the upper wound, forms a distal anastomosis with the SGA.

EFFECT: method enables restoring antegrade blood flow along the superior gluteal artery and arresting high intermittent claudication syndrome.
