[Indications and techniques of surgical intervention in chronic postembolic pulmonary hypertension]

The paper gives indications for surgical management and describes a surgical technique on the basis of the author's experience with 36 reconstructive interventions on pulmonary arteries in persistent post-embolic occlusion. The absolute indication for elimination of occlusion is central pulmonary arterial lesion which exists no more than 3 years and which is accompanied by elevated systolic pulmonary pressure (ranging from 51 to 100 mm Hg) and relatively preserved right ventricular myocardial function. The optimal surgical method is thrombin-thymectomy performed in deep hypothermia using intermittent extracorporeal perfusion.
