Evaluation of Aortic Arch Disorders in Patients with Tetralogy of Fallot

Fallot tetralogy (TOF) is one of the most common diseases among congenital heart cyanotic abnormalities. 25% of these patients have a right aortic arch. On the other hand, the right aortic arch is often associated with syndromes, heterotaxia, and misplaced origins of the aortic branches. Knowing this is necessary for the surgeon before corrective surgery and for drawing a roadmap for less complicated surgery is very helpful and necessary.Therefore, the aim of present study was to determine and evaluate aortic arch disorders in patients with tetralogy of Fallot.

In the present retrospective study, 332 cases of TOF patients were referred by the pediatric cardiology department was reviewed for preoperative angiography during surgery from 2006 to 2016 to the angiography wards of Namazi and Shahid Faghieh hospitals. Had been reviewed. All patients underwent diagnostic angiography before surgery and their angiographic film was reported and recorded. In this study, all existing preoperative angiography records were carefully reviewed and all available information and how to orient the aortic arch and its abnormalities, if any, were recorded. The collected data were analyzed using .chi-squared ... test.

Out of 332 people included in the study, 312 were children and 20 were adults. The age distribution of patients was determined from one month to 36 years. A total of 77 patients (23.2%) had right aortic arch among 208 males and 124 females. In one of these patients, an interupted aortic arch was reported. In terms of sex distribution, right aortic arch was observed in 22.1% of male patients and 24.9% of female patients, which did not show a clear statistical difference (p=0.5). No abnormalities of the aortic branches were seen in this study.

A significant percentage of patients with TOF have right aortic arch (22%) and aortic arch disorders such as a ruptured aortic arch may be seen with it. Knowing the position of the aorta, arch abnormalities, and abnormal branches of the aorta before surgery will be a great help for the surgeon to have a roadmap to reduce intraoperative and postoperative complications and speed the patientchr('39')s recovery.
