A mid-thigh tourniquet technique for lower leg bypass surgery prevents distal anastomotic stenoses. This method ensures faster, drier operations with fewer complications, particularly in small vessels.

Area of Science:

  • Vascular Surgery
  • Surgical Techniques
  • Arterial Reconstruction

Background:

  • Distal anastomotic stenoses are a complication in lower leg bypass surgeries.
  • Traditional clamping methods can cause vessel damage and bleeding.

Purpose of the Study:

  • To evaluate a modified surgical technique using a mid-thigh tourniquet for lower leg bypass operations.
  • To assess the efficacy of atraumatic occlusion in preventing distal stenoses.

Main Methods:

  • A mid-thigh tourniquet inflated to 400 mmHg for 22-73 minutes was used in 75 primary and 18 secondary bypass operations.
  • Procedures included bypasses to anterior tibial, posterior tibial, peroneal, and inframalleolar arteries.
  • Proximal anastomoses were performed under tourniquet inflation in 11 cases.

Main Results:

  • No distal anastomotic stenoses were observed during follow-up.
  • The technique resulted in less bleeding and easier suturing due to intact veins and arterial branches.
  • Operations were faster and drier, with no clamp-induced lumen obliteration.

Conclusions:

  • Mid-thigh tourniquet use is a valuable atraumatic occlusion method for lower leg bypass surgery, especially in small vessels.
  • This technique minimizes complications and improves surgical efficiency.
  • It effectively prevents inflow stenoses in the tourniquet-affected area when the artery is patent.
