Eversion with four sutures: an easy, fast, and reliable technique for microvascular anastomosis

Area of Science:

• Vascular Surgery
• Microsurgery
• Surgical Techniques

Background:

• Microvascular anastomosis is crucial for reconstructive surgery.
• Conventional techniques can be time-consuming and complex.
• There is a need for more efficient and reliable anastomosis methods.

Purpose of the Study:

• To introduce and evaluate a novel "eversion with four sutures" technique for microvascular anastomosis.
• To compare the efficacy and safety of the new technique against the conventional method.
• To assess parameters including operating time, patency, and complication rates.

Main Methods:

• The study involved 120 Wistar-Albino rats, with 240 femoral artery anastomoses performed.
• Both the "eversion with four sutures" technique and a conventional nine-suture technique were applied to each rat.
• Outcomes measured included operating time, bleeding time, suture count, patency rates, pseudoaneurysm formation, and histological healing.

Main Results:

• The "eversion with four sutures" technique demonstrated significantly reduced anastomosis time and less exposed suture material compared to the conventional method.
• No significant differences were observed in patency rates, bleeding times, or pseudoaneurysm formation between the two techniques.
• The new technique was found to be faster, easier, and equally reliable as the conventional method.

Conclusions:

• The "eversion with four sutures" technique is a reliable and efficient alternative to conventional microvascular anastomosis.
• This method offers advantages in reducing procedure time and foreign material in the vessel lumen.
• It is particularly suitable for emergency situations requiring multiple microvascular anastomoses.
