In the surgical correction of aortic coarctation, although various surgical techniques were developed for the prevention of recoarctation, it is still a problem in the current era. In our series, recoarctation is analyzed according to the anatomy of the aorta instead of surgical techniques.

Thirty-eight patients underwent coarctation surgery between April 1993 and February 1997. Risk factors for recoarctation were regarded as the ratio of the diameter of the transverse arch to the diameter of the diafragmatic aorta and the diameter of the isthmus to the diameter of the diafragmatic aorta less than 0,9 and 0,65 respectively.

Eleven patients were in the risk group for the transverse arch diameter, and among these 11 patients 9 patients were also in the risk group for the isthmus diameter.

Recoarctation were observed in 3 patients after the follow up of 28,34±10,84 months, and recoarctation rate was 7,8 % in the overall group, 27,2 % in the risk group.

Recoarctation is not only related to the type of surgery, aortic anatomy also play an important role in recoarctation. High risk patients can be determined by preoperative angiographic examination, and more aggressive surgical interventions can be applied.
