title: [Features of topical diagnosis of postembolic lesions of the pulmonary trunk and main pulmonary arteries].
abstract: Radiopaque and radio-isotope findings in the pulmonary arterial channel in 43 patients with postembolic lesions of the pulmonary trunk and its major branches are reported. Angiographic and scanographic symptoms are described. The significance of detected systolic-pressure gradient in the probing of pulmonary vessels is demonstrated. Possible sources of diagnostic errors are analysed, and ways of eliminating them are suggested. Total and selective multipositional angiopulmonography is believed to be the principal method of diagnosing this condition, while pulmonary scanning only allows topical diagnosis in cases of markedly stenosed major pulmonary arteries.
