PROXIMAL INTERRUPTION OF A PULMONARY ARTERY

Proximal interruption of a pulmonary arch (absence of one pulmonary artery); case report and a new embryologic interpretation.

Proximal interruption of the pulmonary artery: Transcatheter embolization for emergent management of massive hemoptysis

Transcatheter embolization is the first-line treatment for massive hemoptysis and recurrent intractable hemoptysis. Proximal interruption of the pulmonary artery is a rare congenital anomaly characterized by hypertrophy and neovasculsarity of bronchial and nonbronchial aortopulmonary collaterals; hemoptysis complicates a minority of cases. We present a case of unilateral proximal interruption o...

Pulmonary Atresia with Ventricular Septal Defect and Major Aortopulmonary Collaterals Associated with Left Pulmonary Artery Interruption

A multistage plan and multidisciplinary approach are the keys to successful repair in patients with pulmonary atresia (PA) with ventricular septal defect (VSD) and major aortopulmonary collateral arteries (MAPCAs). In this article, we present a multidisciplinary approach adopted to treat a patient with PA with VSD and MAPCAs associated with left pulmonary artery interruption.

Bilateral proximal pulmonary artery aneurysms simulating hilar adenopathy.

Proximal pulmonary artery aneurysms (PAAs) are rare. Most are associated with secondary pulmonary hypertension or a variety of rare systemic disorders. An asymptomatic adult patient presented with bilateral hilar enlargement on a routine chest roentgenogram. Computed tomography of the chest revealed 5 cm bilateral proximal PAAs with a normal pulmonary trunk. The clinician should consider proxim...

Silent Pulmonary Artery Dissection in a patient with old Pulmonary Balloon Valvuloplasty

Percutaneous pulmonary balloon valvuloplasty (PBV) remains the treatment of choice for pulmonary stenosis (PS). This procedure is effective, safe and gives excellent results. Pulmonary artery (PA) dissection is a rare complication of PBV. This report is a case of an asymptomatic 17-year-old male with a history of PBV due to severe PS dating back to fifteen years ago. During recent echocardiogra...
