METHOD FOR PREOPERATIVE ASSESSMENT OF LIKELIHOOD OF EARLY RESIDUAL PULMONARY HYPERTENSION AFTER PULMONARY ENDARTERECTOMY Russian patent published in 2024 - IPC A61B5/08 A61B5/91 A61B8/06 

FIELD: medicine; cardiovascular surgery.

SUBSTANCE: proposed invention can be used for preoperative assessment of the likelihood of early residual pulmonary hypertension after pulmonary endarterectomy. The patient’s body mass index is determined, whether patient’s blood group belongs to A (II) is determined, the patient’s expiratory reserve volume, minute respiratory volume and bronchopulmonary resistance are measured using body plethysmography, and the left ventricular ejection fraction is determined using transthoracic echocardiography. Using the obtained indicators, the probability of early residual pulmonary hypertension after pulmonary endarterectomy is determined according to the given formula.

EFFECT: proposed method makes it possible to optimize patient management tactics by correcting modifiable risk factors for early residual pulmonary hypertension before a planned operation in individuals with a high probability of its development by assessing the totality of the most significant indicators.
