The key pathophysiologic component of PPHN is almost always elevated PVR. There are very few conditions in which increased PBF is an important component of PPHN.[nature.com]
We describe here in detail this rare case of multiple FNH syndrome associated with lung and spinal arteriovenous malformations (AVM), and briefly discuss the possible pathophysiology underlying the association of these apparently unrelated lesions.[em-consulte.com]
This implies that the pathophysiology of the arteriovenous malformations in these conditions is dilation of the normal capillary bed.[emedicine.medscape.com]
If surgical redirection of hepatic venous flow to the pulmonary arterial system is possible, it should be undertaken to prevent or treat the pulmonary arteriovenous malformations and their sequelae.[icvts.oxfordjournals.org]

Treatment & Prevention Treatments for arteriovenous malformations vary on a case-by-case basis and depend on the size and location of the AVM.[vascularcures.org]
Surgery — Removing the AVM is the surest way of preventing it from causing future problems. Often surgery is recommended for AVMs that are close to the surface, but it may be too difficult or risky for deeply located or very large ones.[luriechildrens.org]
With microsurgery, we perform a neurosurgery to visualize the AVF under a microscope and we place a titanium clip over the abnormal connection to prevent blood from flowing abnormally from the artery to the vein.[mountsinai.org]
