title: [Efficiency of Operation Trombendarterektomy From Pulmonary Artery Branches Depending on the Degree of Pulmonary Hypertension and Duration of Disease].
abstract: OBJECTIVE
  to assess effect of thromboendarterectomy from pulmonary artery branches on clinical functional state of patients with chronic thromboembolic pulmonary hypertension (CTEPH) in dependence on degree of pulmonary hypertension and disease duration.
  
  
  METHODS
  Patients (n=152) were divided into 3 groups: (1) with systolic pulmonary artery pressure (SPAP) less or equal 50 mm Hg (n=20), (2) with SPAP>50- less or equal 80mm Hg (n=46), (3) with SPAP >80mm Hg (n=86).
  
  
  METHODS
  Examination included registration of dynamics of general clinical state and character of complaints, six-minute walk test, transthoracic echocardiography with measurement of SPAP and right ventricular ejection fraction, pulmonary perfusion scintigraphy with calculation of index of perfusion deficit.
  
  
  CONCLUSIONS
  Pulmonary thromboendarterectomy from pulmonary artery branches was associated with stable improvement of clinical functional state of patients with CTEPH and regression of symptoms irrespective of preoperative level of pulmonary hypertension.
