This report describes 2 symptomatic patients with phrenic nerve palsy due to Parsonage-Turner syndrome who were managed by diaphragmatic plication. The characteristics of the underlying syndrome are defined.

Comparative Study
Staged approach prevents spinal cord injury in hybrid surgical-endovascular thoracoabdominal aortic aneurysm repair: an experimental model.
In a porcine model, we investigated the impact of sudden stent graft occlusion of thoracic intercostal arteries after open lumbar segmental artery (SA) ligation. ⋯ These results underline the potential of the staged approach in hybrid procedures. Furthermore they highlight the need for established adjuncts for preventing paraplegia in hybrid and pure stent-graft protocols in which sudden occlusion of multiple SAs occurs.

Comparative Study
The right internal thoracic artery: the forgotten conduit--5,766 patients and 991 angiograms.
The right internal thoracic artery (RITA) is biologically identical to the left ITA, yet is rarely used in coronary artery bypass graft surgery (CABG). We examined the results and long-term patency of RITA grafts. ⋯ Late patencies of RITA are excellent, equivalent to the LITA for identical territories, always better than radial arteries and saphenous vein grafts, and remain free of atheroma. Use of RITA in addition to LITA is associated with excellent survival in triple-vessel coronary disease. More extensive use of the RITA in CABG is recommended.

In contrast to mitral valve repair, residual and recurrent regurgitation after tricuspid valve (TV) repair for functional tricuspid regurgitation (TR) is common. We have systematically used undersized, rigid 3-dimensional annuloplasty rings to treat functional TR. ⋯ Tricuspid valve repair with an undersized (size 26 or 28) rigid 3-dimensional annuloplasty ring is the method of choice for reliable and durable treatment of functional TR.

This study evaluated the role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the assessment of newly developed mediastinal/hilar abnormalities in patients with previously treated lung cancer. ⋯ EBUS-TBNA can differentiate a new primary lung cancer from recurrence of previously treated lung cancer, which will facilitate treatment strategy.
