Objective: Pulmonary artery aneurysms (PAA) are rare diseases generally diagnosed coincidentally. Although most of the PAA patients are asymptomatic, they can be symptomatic due to complications such as rupture, pulmonary valve leakage, thromboemboli, dissection and pressure on coronary arteries and pulmonary valve. Our aim in this study was to compare plication and graft usage techniques in PAA operations. Material and Method: A total of 11 patients who had elective PAA operation between January 1, 2010 and December 31, 2018 in our clinic and had registered demographical information were retrospectively examined. Patients included in the study were separated into two groups as those who had plication in PAA (Group 1) and those who had tube graft change in PAA (Group 2). There were six patients in Group 1 (2 F, 4 M) and five patients (2 F, 3 M) in Group 2. Preoperative and postoperative data of the patients in both groups were registered and examined in detail. Findings: Among the 11 patients who had surgical repair due to PAA, seven were male and four were female. Although the ages of the patients changed between 38 and 65, the average age was 53.4 years. There was no significant difference in diabetes mellitus, hypertension, coronary artery disease among the groups. Chronic obstructive pulmonary disease (COPD) was observed more in Group 1. Operations were made under cardiopulmonary bypass. Aortic cross clamp duration (ACC) was 96 +/- 18 minutes in Group 1 and 105 +/- 22 minutes in Group 2 (p>0.05). Average intensive care unit hospitalization duration of the patients was 2.5 +/- 1.5days in Group 1 and 3.4 +/- 1.5 days in Group 2 (p<0.05) but no statistically significant difference was found among the average hospitalization durations of the patients (p>0,05). Result: Although observed frequently, PAA can cause mortality especially due to causes such as rupture and dissection. Surgical intervention is required in patients with PAA over 5,5 cm. Although different views are available in literature, in our study, we detected tube graft usage to be more effective in surgical treatment. As there is a change of aneurysm reformation in postoperative followups of the patients who had plication especially, we suggest graft usage in PAA surgical treatment.
