[Pulmonary hypertension and the possibilities of its radiographically guided endovascular correction in chronic nonspecific lung diseases].
Bronchial arteriography and catheterization of the pulmonary artery (PA) were applied in the examination of 120 patients with chronic nonspecific diseases of the lungs. The specific features of bronchopulmonary blood circulation in various pathological processes were revealed. Pulmonary hypertension (PH) was encountered in 71.5% of cases, and pressure in the PA was significantly higher in the group of patients with massive bronchopulmonary blood shunting (chronic pulmonary suppurations) than in the group of patients with minimal blood shunting (nonsuppurative processes). Radiologically-guided endovascular correction of the disorders of the bronchopulmonary blood flow was conducted in 85 patients by occlusion of the bronchial arteries (BA). Pressure in the PA significantly reduced after the correction due to diminished left-to-right blood shunting. Thus, besides the generally known mechanisms, bronchopulmonary shunting of blood plays a certain role in the pathogenesis of PH in chronic suppurative processes. Endovascular BA occlusion for correction of PH in patients with bilateral lesions is expedient.
