Evaluation of Feasibility of Ultrasonography Guided Pulmonary Artery Catheterization in Pulmonary Hypertension Diagnosis

pulmonary artery catheterization for hemodynamics assessment patients with suggestion of having certain pulmonary hypertensions groups is vital for establishing their managements; few tools are used to facilitate catheter insertion including monitor waves form, fluoroscopic guidance and to lesser extent sonographics guidance. sonographic guidance is not fully studied in pulmonary hypertenison patients however it carries advantages over radiographic guidance of being less exposure to radiation for both the patients and health care team. with increasing pulmonary hypertension units allover the worlds and patients recognitions in addition to availability of ultrasonography that necessitate this study to evaluate sonographic guidance in pulmonary hypertension patients
