[Transplantation of a minute artery to bridge over the defect of an artery of significantly larger calibre. An experimental study].
Based on our clinical experience for years of "unequal bite" suturing technique to perform end-to-end anastomosis of vessels with great discrepancy in diameter, the animal experimental study was carried out. An artery defect, 1.0-1.4 mm in diameter, was reunited with, an autogenous arterial graft of 0.3-0.4 mm in diameter. A high patency rate (96% in total) was obtained postoperatively. Histological examination by light microscope and scanning electron microscope showed that the unequal bite suturing technique can produce very smooth anastomotic junction and the minute arterial grafts healed well on a large artery. The unequal bite suturing technique is a very valuable development of the basic end-to-end anastomotic technique. A small autogenous arterial graft may be used to repair defect of an artery with large calibre clinically.
