Total Pulmonary Torsion Without Vascular Compromise—

Abstract

A new case of pulmonary torsion is reported. Only 15 cases of this rare entity have been published in the literature, all of them either surgically treated short term or resulting in death. Small right-side pneumothorax following diagnostic transthoracic puncture seemed to be the mechanism of production. Because of the absence of acute clinical manifestations, fibroscopy, isotopic perfusion scan ning, and hemodynamic and pulmonary angiographic studies were done. The lack of compromise in the pulmonary flow and venous pulmonary return ex plains the surprisingly good progress (ten months, at present) of the patient.
