Normalization of Pulmonary Vascular Resistance Long After Successful Primary Sutureless Repair for Congenital Pulmonary Vein Stenosis.
Summary of "Normalization of Pulmonary Vascular Resistance Long After Successful Primary Sutureless Repair for Congenital Pulmonary Vein Stenosis."
A 3-month-old infant with perimembranous ventricular septal defect (VSD) and pulmonary hypertension presented at our center. Cardiac catheterization showed a systolic pulmonary-to-systemic arterial pressure ratio of 0.99 and a pulmonary vascular resistance of 9.32 μm(2). Pulmonary angiography showed focal orifice stenosis in the right lower and left lower and upper pulmonary veins, whereas the right upper pulmonary vein was atretic. Sutureless pericardial marsupialization concomitant with VSD patch closure was used to repair the three stenotic veins. Administration of home oxygen therapy and sildenafil citrate was continued after surgical repair. Postoperative catheterization 1.5 years after surgery showed patency of the three repaired veins and normalization of pulmonary vascular resistance.

Measurement of pulmonary vascular resistance (PVR) is essential in evaluating a patient with pulmonary hypertension.
Pulmonary vascular capacitance (PVC) is reduced in pulmonary arterial hypertension (PAH). In normal lung PVC is largely a function of vascular compliance. In PAH, increased resistance (PVR) arises fro...

Vasopressors are gaining renewed interest as treatment adjuncts in hemorrhagic shock. The ideal vasoconstrictor will increase systemic blood pressure without increasing pulmonary vascular resistance (...

Medical and Biotech [MESH] Definitions
Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.
The vascular resistance to the flow of BLOOD through the CAPILLARIES portions of the peripheral vascular bed.
A prostaglandin that is a powerful vasodilator and inhibits platelet aggregation. It is biosynthesized enzymatically from PROSTAGLANDIN ENDOPEROXIDES in human vascular tissue. The sodium salt has been also used to treat primary pulmonary hypertension (HYPERTENSION, PULMONARY).
Pathological process resulting in the fibrous obstruction of the small- and medium-sized PULMONARY VEINS and PULMONARY HYPERTENSION. Veno-occlusion can arise from fibrous proliferation of the VASCULAR INTIMA and VASCULAR MEDIA; THROMBOSIS; or a combination of both.
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
