    a Centro de Investigaciones Biológicas, Consejo Superior de Investigaciones Científicas (CSIC), and Centro de Investigación Biomédica en Red de Enfermedades Raras (CIBERER) , Madrid , Spain.
    Introduction: Hereditary Haemorrhagic Telangiectasia (HHT) is as an autosomal dominant trait characterized by frequent nose bleeds, mucocutaneous telangiectases, arteriovenous malformations (AVMs) of the lung, liver and brain, and gastrointestinal bleedings due to telangiectases. HHT is originated by mutations in genes whose encoded proteins are involved in the transforming growth factor β (TGF-β) family signalling of vascular endothelial cells. In spite of the great advances in the diagnosis as well as in the molecular, cellular and animal models of HHT, the current treatments remain just at the palliative level. Read More

    Division of Pulmonary and Critical Care Medicine, Massachusetts General Hospital, Boston, MA 02114.
    t Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler-Weber-Rendu Disease, is an autosomal dominant genetic disorder that is characterized by the abnormal development of blood vessels. While the pathophysiology underlying the development of pulmonary hypertension (PH) in patients with HHT is not fully understood, it is believed to occur by one of two mechanisms: increases in pulmonary vascular resistance or cardiac output. In the following report, we describe an interesting case of a 26-year-old woman with HHT whose right heart catheterization initially demonstrated PH with elements of both pre- and post-capillary PH.

    Radiographics 2017 Jul-Aug;37(4):1270-1289
    From the Department of Radiology, Mayo Clinic Arizona, Phoenix, Ariz (R.S.P., C.O.M.); Mallinckrodt Institute of Radiology, Washington University School of Medicine, St Louis, Mo (C.J.N., C.A.R., V.M.M., S.B.); Department of Radiology, NYU Winthrop Hospital, Mineola, NY (D.S.K.); Stony Brook University School of Medicine, Stony Brook, NY (D.S.K.); and Neuroradiology Section, Department of Radiology, Phoenix Children's Hospital, Phoenix, Ariz (P.C.).
    Pregnancy results in substantial hemodynamic and prothrombotic changes that form the foundation for downstream vascular complications, both during pregnancy and in the postpartum period. In addition, several important risk factors, including older patient age, diabetes, and smoking, can increase the risk for vascular-related pregnancy complications. Because radiologists often play an important role in evaluation of the pregnant patient, understanding the pathophysiology of vascular-related complications in pregnancy and their imaging appearances is essential for diagnostic accuracy.
