Surgical Treatment of Femoral Artery Bifurcation Without Material: Technique and Follow-Up.

BACKGROUND: Complete eversion of the femoral tripod is interesting to reduce clinical consequences of wound infection, in particular for patients at a high risk (e.g., obese, diabetics, cancer). Experience and follow-up of this technique are scarce. The different technical possibilities and results are reported here. METHODS: A single-center prospective study including patients operated on for femoral occlusive lesions using eversion of the common femoral artery and its bifurcation. Clinical and imaging preoperative data, surgical technique, and follow-up are detailed. RESULTS: Thirty five patients (37 limbs) have been included between June 2014 and April 2016. The mean Rutherford index was 3.6 and 65% of the patients were claudicants. Lesions were limited to the common femoral artery in 14 (38%) of the cases and spread to the superficial femoral artery in 2 (7%) and to the 3 branches in 21 (57%) of the cases, respectively. Postoperatively, one death, one major amputation, and 3 reinterventions were noted, resulting in an 8% rate of major complications. The mean follow-up was 37 months. At this time, 11 major adverse cardiovascular events, 9 deaths, and no additional major amputation were noted. The mean Rutherford index was 1.7 (P < 0.001) and 3 reinterventions were necessary (one for septic occlusion at 3 months and 2 for restenosis at 12 and 42 months), translating into primary and secondary patency rates of 93.3% and 96.1%, respectively. CONCLUSIONS: This work further confirms that eversion of the femoral tripod is safe and effective. This experience adds to the existing body of the literature and describes alternative techniques of eversion. The technique should be considered when treating patients at a high risk of postoperative infection.

Current laser applications in reconstructive microsurgery: A review of the literature.

BACKGROUND: Microvascular surgery has become an important method for reconstructing surgical defects following trauma, tumor resection, or burns. Laser-assisted microanastomoses (LAMA) were introduced by Jain in 1979 in order to help the microsurgeon reduce both operating time and complications. This article reviews the literature on clinical applications of LAMA. METHODS: A Medline literature search was performed and cross-referenced. Articles between 1979 and 2014 were included. Keywords used were laser, laser microanastomoses, laser microanastomosis, LAMA, and microsurgery. RESULTS: Only seven clinical studies using three different wavelengths were found in the literature: 1,064 nm (Nd: YAG), 10,600 nm (CO2), 514 nm (Argon), and 1,950 nm (Diode). Clinical outcomes, type of procedures, laser wavelength and parameters, and possible wider applications in the operating room are discussed in each case. CONCLUSIONS: The success rate for reconstructive free flap surgery and hand surgery achieved with LAMA appears promising. In particular, use of the 1950-nm diode laser for microsurgery is likely to increase in the near future.
