Perioperative Management of a Large Idiopathic Pulmonary Artery Aneurysm Without Pulmonary Arterial Hypertension

Pulmonary Artery Aneurysm Associated With Severe Pulmonary Hypertension in a Patient Presenting for Double Lung Transplant: Review of a Rare Disorder and Role of Transesophageal Echocardiography

Pulmonary artery aneurysm (PAA) is a rare disorder that may be classified as congenital, acquired, or idiopathic, in the case of unclear etiology. When associated with severe idiopathic pulmonary arterial hypertension, such a case of PAA may present to the operating room as an indication for lung transplantation. In this article, we present such a case of a patient with a giant main and right PAA that underwent a double lung transplant. We describe the pathophysiology and natural course of this PAA and discuss the role of intraoperative transesophageal echocardiography in the management of patients with this rare diagnosis.

Anaesthesia Management in Idiopathic Pulmonary Artery Aneurysm Surgery

Pulmonary artery (PA) aneurysm is a very rare disease. Surgical treatment is important in symptomatic patients. Due to its anatomical condition, the rupture of such aneurysms may lead to sudden right ventricular failure or sudden death. The aim of this report is to present the use of balanced general anaesthesia management in a patient who underwent PA aneurysm repair surgery. Surgical repair was planned in a 55-year-old man with chest and back pain as well as haemoptysis. With the help of balanced anaesthesia, stress on the aneurysm wall was prevented by avoiding sudden blood pressure increases. With appropriate ventilation methods, we attempted to avoid an increase in pulmonary vascular resistance, and therefore, the pressure on the aneurysm, as well as an increase in the postoperative right ventricle. With the help of appropriate anaesthesia and ventilation techniques, uncomplicated and successful anaesthetic management was effected in the repair of a PA aneurysm.

Minimally Invasive Pulmonary Artery Aneurysm Repair Through a Left Anterior Minithoracotomy-an Alternative Approach

The purpose in this case was to repair a less invasive approach than a standard sternotomy. Workup of asymptomatic patient with computerized tomography scan of chest revealed pulmonary artery aneurysm and transesophageal echocardiography demonstrated flow stagnation in aneurysm. An alternative minimally invasive approach was performed to repair the pulmonary artery aneurysm with plication through a left anterior minithoracotomy using normothermic cardiopulmonary bypass with percutaneous peripheral cannulation, instead of median sternotomy. Post-repair transesophageal echocardiography demonstrated normal flow in the pulmonary artery. The patient had an uneventful postoperative course and was seen in the outpatient clinic with excellent recovery. Minimally invasive repair of pulmonary artery aneurysm through a left anterior minithoracotomy is a feasible alternative approach. Minimally invasive repair of pulmonary artery aneurysm through a left anterior minithoracotomy is a feasible alternative approach.

Transcatheter embolization for idiopathic peripheral pulmonary arterial aneurysm: A case report

The natural history of idiopathic peripheral pulmonary arterial aneurysms (PAAs) is unclear; however, they can cause sudden death by rupture. Our case illustrates the utility and low invasiveness of transcatheter embolization using an AMPLATZER™ Vascular Plug 4 and hydrogel-coated metallic coils in patients with idiopathic peripheral PAAs.
