Pulmonary varices: a case report and review of the literature.

A case of a 47-year-old woman with pulmonary varix is reported herein. Saccular dilatation of the inferior pulmonary vein resembled a pulmonary perihilar mass which could not be palpated at the time of thoracotomy. Aneurysmal dilatation of the pulmonary vein, otherwise known as pulmonary varix, is rare. Only 71 such cases, including 17 cases in Japan, have been reported. Pulmonary varices may be classified into three types, namely: saccular type, tortuous type and confluent type. Most of the varices seen in patients with valvular disease have been of the confluent type (62 per cent), however tortuous type varices have also been seen in some cases (19 per cent). Pulmonary venous hypertension may be one of the major causes of confluent type pulmonary varices as regression of pulmonary varices after mitral valve replacement has been reported. None of the saccular type cases, however, were accompanied by valvular disease. This indicates that local factors may also be an important cause of saccular type varices.

Rotator interval lesion.

Arthrography and surgical exploration reveal the pathogenesis of a painful shoulder syndrome characterized by inferior instability in the rotator interval (RI). The RI is the space between the subscapularis and the adjacent supraspinatus interval. Two types of RI lesions can be identified. Type I, a contracted state, is characterized by inflammatory changes in superficial bursal area. In Type II, an unstable condition is associated with extensive inflammation of deeper tissues in the RI. In a series of 101 patients, including 106 shoulders with RI lesions, surgical repair of the RI was performed with the shoulder in an externally rotated position. This position ensured a close fit of the supraspinatus and the subscapularis attachments. Of 78 shoulders evaluated in a follow-up study, 96% were graded good or excellent, and 4% poor. This investigation presents evidence for the importance of diagnosis and treatment of RI lesions in patients with persistent pain in the shoulder.
