A Novel Approach for the Treatment of Pulmonary Artery Aneurysm Repair Using Inclusion Technique: A Case Report

Mariana Flaifel et al. Cureus. .

Abstract

Pulmonary artery aneurysm (PAA) is a rare disease with life-threatening complications, especially when accompanied by pulmonary artery hypertension. Due to its rarity, there are currently no specific guidelines for the treatment of PAA. Several surgical techniques have been described to be beneficial in the treatment of PAA originating at the pulmonary trunk. However, several adverse complications have been described for traditional techniques. In this case, we present the first successful repair of PAA with idiopathic pulmonary artery hypertension using a graft inclusion technique.

Keywords: aneurysm; aneurysmectomy; cardiac surgery; graft inclusion; pulmonary artery.

(a) Longitudinal incision of the pulmonary artery (PA). Care is taken to visualize the pulmonary valve (PV) and avoid extending up the incision into the PV annulus. The cranial incision was extended to visualize the left and right PAs. (b) Anastomosis of 30mm Dacron prosthetic caudally 1-2 cm above the PV. Cranial anastomosis is performed with care ensuring the right and left PAs are unobstructed. Anastomosis is done using continuous 3-0 prolene sutures. (c) Enclosing the graft with pulmonary vessel walls using a continuous suturing technique.
