Clinical Relevance of Computed Tomography Pulmonary Venography

Abstract

Computed tomography pulmonary venography must be considered before atrial septal defect (ASD) closure and pulmonary lobectomy. Computed tomography pulmonary venography should be considered for patients with right ventricular overload and pulmonary hypertension, as well as for patients with unclear recurrent pulmonary infections, progressive dyspnoea, pleural effusions, haemoptysis, and for patients with respiratory distress after lung-transplantation.

Dual‐energy computed tomography‐angiography in the evaluation and management of significant multiple pulmonary vein stenoses following atrial fibrillation ablation

“…This mechanism causes specific perfusion defects on iodine maps. 6,7 There are several interventional options for PV stenosis treatment, and the management of multivascular and bifurcation PV lesions is particularly difficult. Previous reports have shown the advantage of peripheral larger stents over balloon angioplasty and smaller size drug-eluting coronary stents for patients with PV stenosis following atrial fibrillation ablation.…”

“…Perfusion redistribution due to PV stenosis is an important compensatory mechanism that leads to a decrease in blood flow in those parts of the lungs from which the venous outflow is disrupted. This mechanism causes specific perfusion defects on iodine maps 6,7…”

Lungenvenenfehlmündung als Ursache für arterielle Blutgaswerte nach ZVK-Anlage

“…Einleitung Partielle Lungenvenenfehlmündungen (PAPVR) sind mit 0,1-0,5% seltene angeborene Gefäßvariationen 1 2 . Je nach Variante sowie assoziierten Herzfehlern, insbesondere Atriumseptumdefekten (ASD), treten Symptome bereits in der Kindheit oder erst im Erwachsenenalter als Folge des persistierenden Links-Rechts-Shunts auf 1 .…”
