Neo-Revascularization as the Potential Treatment for Patient Suffering from Pulmonary Arterial Hypertension (Myth or Reality)

Abstract

Pulmonary arterial hypertension (APAH, IPAH) is a devastating, progressive disease with increasingly debilitating symptoms [1,2].Intrapulmonary delivery of autologous stem cells could be beneficial for pathogenetic treatment for patients with severe pulmonary arterial hypertension.Two patients with severe pulmonary artery hypertension received intrapulmonary autologous mesenchymal (mononuclear) stem cell transplantation and stem cell transplantation in pulmonary arteries. Patients were examined by scintigraphy of lungs during the periods 12, 14 and 27 months after stem cell transplantation. We find out that perfusion in all lung segments were improved after 14 and 27 months.
