Chronic thromboembolic pulmonary hypertension (CTELG)

History

2022: Russia performed a unique version of pulmonary artery angioplasty

In April 2022, it became known about the implementation in Russia of a unique version of pulmonary artery angioplasty. This is the achievement of cardiologists of the National Medical Research Center for Cardiology named after Academician E.I. Chazov.

They performed one-stage enduscular revascularization of proximal occlusion of two lobed branches of the pulmonary artery in a 62-year-old patient with chronic thromboembolic pulmonary hypertension (CTELG).

In April 2022, it became known about the implementation in Russia of a unique version of pulmonary artery angioplasty.

She entered the hypertension department of the Research Institute of Clinical Cardiology named after A.L. Myasnikova NMITS of Cardiology with complaints of shortness of breath when walking up to 150 m, dizziness, general weakness. According to the results of the examination, chronic thromboembolic pulmonary hypertension was diagnosed. According to angiopulmonography, the patient was determined mainly one-sided lesion in the form of occlusion of lobular branches of the right pulmonary artery with an average pressure of 60 mm Hg in it. By the decision of the multidisciplinary commission, the patient was declared inoperable due to the unacceptable ratio of potential risk and benefit of surgery, endascular treatment was recommended.

After standard preparation, the patient underwent angioplasty of the occluded middolar and inferior branches of the right pulmonary artery using access through the superficial vein of the right upper extremity. The features of the lesion did not imply a phased opening of these branches, and blood flow was completely restored in one intervention. Within only 1.5 hour, it was possible to achieve complete revascularization of the affected vessels and restore blood supply in the corresponding lobes of the lung.

As noted in the NMIC of Cardiology. ACOD E.I. Chazov, the method of choice in the treatment of chronic thromboembolic pulmonary hypertension is the operation of thrombendarterectomy from the branches of the pulmonary artery. Surgery for CTELH is an effective treatment, but in a number of cases it involves a high risk of complications, or is not possible at all.^[1]
