[Efficiency of Pulmonary Ventilation in Remote Period After Surgery in Patients With Chronic Pulmonary Thromboembolism].

AIM: to assess efficiency of pulmonary ventilation in remote period after surgical treatment of chronic pulmonary thromboembolism (CPTE).

MATERIAL AND

METHODS

We examined 29 patients with CPTE with median age 49 (38-60) years. Pulmonary ventilation was studied by body plethysmography and its efficiency was evaluated by oxygen utilization coefficient (OUC).

RESULTS

Comparison of OUCs before and in the remote period after surgery showed that after surgical treatment efficiency of pulmonary ventilation increased by 26% at the account of reduced hyperventilation but remained below normal. Patients' age and duration of the disease had a direct impact on the baseline bronchial conductivity as well as on recovery of the respiratory system reserve in the remote period after surgery.
