SIMONIN-RUIZ, Óscar D. et al. Anomalous origin of one of the branches of the pulmonary artery (AOPA): Surgical treatment and outcome. Rev. Colomb. Cardiol. [online]. 2021, vol.28, n.5, pp.438-443.  Epub 29-Nov-2021. ISSN 0120-5633.  https://doi.org/10.24875/rccar.m21000081.

Introduction:

The anomalous origin of one of the branches of the pulmonary artery from the ascending aorta is rare.

Objective:

To identify the clinical and surgical characteristics of the patients undergoing reimplantation of the affected branch.

Method:

An observational, cross-sectional, descriptive, retrospective and retrolective study was performed; patients diagnosed with anomalous origin of one of the branches of the pulmonary artery and treated by corrective surgery at the Instituto Nacional de Cardiología Ignacio Chavez, in the period from January 1, 2003 to January 31, 2019, were included. It was extracted from the files: demographic characteristics, surgical antecedents, diagnoses, echocardiographic and tomographic reports, surgical technique and post-surgical status.

Results:

Nine patients underwent correction surgery, with an average age of 2 ± 2 years, 11.4 ± 1.5 kg and height 82 ± 15 cm; 67% were male. The most frequent affected branch was the right, 68% originated directly from the aorta and 42% from a patent ductus arteriosus. The correction with extracorporeal circulation had an average aortic cross-clamp of 35 minutes and circulatory support of 45 minutes, the direct or synthetic implant was used. The complications were ventricular failure, bleeding, arrhythmias and nosocomial pneumonia. Mortality was 11%.

Conclusions:

Surgical treatment for reimplantation of the anomalous branch of the pulmonary artery is the procedure of choice, which with surgical and subsequent care has a good prognosis in the medium and long term.
