Pulmonary artery sling

The Journal of Thoracic and Cardiovascular Surgery, 1975
Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availability of a corrective operation, the mortality rate remains very high (50 per cent of surgically treated children) due to the high incidence of associated obstructive anormaliies of the tracheobronchial tree.

Isolated major aortopulmonary collateral as the sole pulmonary blood supply to an entire lung segment [PDF]

, 2017
Congenital systemic-to-pulmonary collateral arteries or major aortopulmonary collaterals are associated with cyanotic congenital heart disease with decreased pulmonary blood flow.

Bronchial Circulation Angiogenesis in the Rat Quantified with SPECT and Micro-CT [PDF]

, 2008
Introduction As pulmonary artery obstruction results in proliferation of the bronchial circulation in a variety of species, we investigated this angiogenic response using single photon emission computed tomography (SPECT) and micro-CT.

Pulmonary arterial hypertension

Medicina, 2007
Pulmonary arterial hypertension is a life-threatening, progressive disorder of pulmonary blood vessels leading to an increase in pressure in pulmonary artery. Diagnosis is based on a mean pulmonary artery pressure of more than 25 mmHg at rest or more than 30 mmHg during exercise. No cure exists for it yet.

Transcatheter embolization of a Rasmussen aneurysm via pulmonary artery with n-butyl cyanoacrylate and iodized oil mixture injection with balloon occlusion

Journal of Vascular Surgery Cases and Innovative Techniques, 2016
We describe a new approach to effective embolization of Rasmussen aneurysm by simultaneous devascularization of the pseudoaneurysm and systemic artery-to-pulmonary artery anastomoses.

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.

Flow characteristics of the proximal pulmonary arteries and vena cava in patients with chronic thromboembolic pulmonary hypertension: correlation between 3.0 T phase-contrast MRI and right heart catheterization

Diagnostic and Interventional Radiology, 2014
PURPOSEWe aimed to determine the correlation between flow characteristics of the proximal pulmonary arteries and vena cava obtained by 3.0 T phase-contrast magnetic resonance imaging (MRI) and hemodynamic characteristics by right heart catheterization in

Reconstruction of anomalous left coronary artery from pulmonary artery in an adult patient: a case report

Journal of Cardiothoracic Surgery, 2019
Background Anomalous left coronary artery from the pulmonary artery is a congenital heart disease in which myocardial ischemia occurs within 1 year of birth. Adults have been reported to survive owing to the development of collateral perfusion from right

Persistent Vascular Collagen Accumulation Alters Hemodynamic Recovery from Chronic Hypoxia [PDF]

, 2012
Pulmonary arterial hypertension (PAH) is caused by narrowing and stiffening of the pulmonary arteries that increase pulmonary vascular impedance (PVZ). In particular, small arteries narrow and large arteries stiffen. Large pulmonary artery (PA) stiffness
