Pulmonary hypertension caused by pulmonary venous hypertension.
The effect of pulmonary venous hypertension (PVH) on the pulmonary circulation is extraordinarily variable, ranging from no impact on pulmonary vascular resistance (PVR) to a marked increase. The reasons for this are unknown. Both acutely reversible pulmonary vasoconstriction and pathological remodeling (especially medial hypertrophy and intimal hyperplasia) account for increased PVR when prese...
متن کاملEffect of Sildenafil in Primary Pulmonary Hypertension
Primary pulmonary hypertension is a disorder with limited treatment options and poor outcome. We demonstrated a beneficial role of sildenafil, a phosphodiesterase 5 inhibitor, in a patient with primary pulmonary hypertension. After the initiation of sildenafil the pulmonary artery pressure decreased from 40/20mmHg to 16/6mmHg, while mean pulmonary arterial systolic pressure decreased from 25mmH...
متن کاملPulmonary Embolism Caused by Popliteal Venous Aneurysm
Venous aneurysms are uncommon in the lower limb and are more frequently found in the neck and thoracic and visceral veins. However, they have been reported to cause thrombosis, pulmonary thromboembolism, and other related complications. Popliteal venous aneurysms are often undetected because they are usually asymptomatic, but they may cause pulmonary thromboembolic events. We experienced a case...
متن کامل[Pulmonary embolism caused by elemental mercury].
Intravenous mercury administration is a rare occurrence that is typically associated with accidental injections or suicide attempts. We report the case of a 42-year-old man who attempted suicide by injecting mercury into the left cubital vein. Upon arrival at the emergency department, he was in a state of alcohol intoxication and there were signs of vein puncture and cellulitis in his left arm....
متن کاملBeneficial effects of phosphodiesterase 5 inhibition in pulmonary hypertension are influenced by natriuretic Peptide activity.
BACKGROUND Phosphodiesterase type 5 (PDE5) inhibitors (eg, sildenafil) are a novel, orally active approach to the treatment of pulmonary arterial hypertension. The role of natriuretic peptides in the response to sildenafil was examined in mice lacking NPR-A, a guanylyl cyclase-linked natriuretic peptide receptor, in which pulmonary hypertension was induced by hypoxia. METHODS AND RESULTS Mice...
