[Chronic unilateral obstruction to pulmonary venous return. A study on 6 cases and review of the published literature (author's transl)].
The authors describe 6 cases of unilateral obstruction to pulmonary venous return: two cases of Halasz syndrome and postoperative obstruction of the reimplanted collector vein, one patient with Halasz syndrome and spontaneous obstruction of the vein in the form of a scimitar, one case of neoplastic invasion of the atrium-vein junction, one with unilateral absence of the right intra- and extraparenchymatous regions of the pulmonary veins, and lastly, a case of juxta-auricular interruption in the right pulmonary veins. The anatomy and physiopathology of the collateral venous pathways are briefly described, together with the relations between systemic arterial hypervascularization and pulmonary venous obstruction. The authors then review the radiological, clinical, and angiohemodynamic features of the unilateral venous obstruction syndrome, and conclude that precise diagnosis of venous occlusion, its location, and its tolerance are essential for deciding the therapeutic measures required.
