Case Reports
Endovascular repair of ruptured aberrant left subclavian artery with right aortic arch.
Association of a right-sided aortic arch with an aberrant left subclavian artery is rare. We present a case of successful endovascular repair of a ruptured Kommerell diverticulum associated with a right-sided aortic arch and aberrant left subclavian artery. ⋯ We managed the rather hostile neck with an extra-large Palmaz stent. A left carotid-to-subclavian bypass with an 8-mm Dacron graft was also performed to restore left arm perfusion and prevent vertebrobasilar insufficiency.

Acute kidney injury in patients undergoing cardiac surgery and coronary angiography on the same day.
Contrast media used for coronary angiography may result in a contrast-induced nephropathy. Acute kidney injury (AKI) is a common complication of cardiac surgery. It has been hypothesized that cardiac surgery in close succession to coronary angiography may increase the risk of postoperative AKI. However, data from the existing literature are conflicting. The aim of this study is to investigate the risk of AKI in patients undergoing angiography and cardiac surgery on the same day, and to assess the efficacy of a policy limiting this practice. ⋯ Acute kidney injury after cardiac surgery is a multifactorial event; surgery on the same day of angiography significantly increases the risk of AKI, and limiting this practice results in a containment of the postoperative AKI incidence.

The impetus for aortic valve (AV) repair is to decrease valve-related complications in comparison to prosthetic valve replacement. However, relatively few data are available to confirm this hypothesis. We analyzed valve-related complications in a large series of patients undergoing AV repair. ⋯ The current findings confirm that AV repair is associated with low mortality, acceptable durability, and a low risk of valve-related events.

Loeys-Dietz syndrome can present with cardiovascular complications in infancy. We report the successful surgical management in a 1-month-old infant with Loeys-Dietz syndrome of a ductus arteriosus aneurysm with an unexpected contained rupture found at the time of surgery.

Clinical Trial
Feasibility and safety of nonintubated thoracoscopic lobectomy for geriatric lung cancer patients.
The feasibility and safety of thoracoscopic lobectomy using anesthesia without tracheal intubation for treatment of geriatric non-small cell lung cancer patients is unclear, although it has been used with success in younger populations. ⋯ Nonintubated thoracoscopic lobectomy is technically feasible and was as safe as thoracoscopic lobectomy performed with tracheal intubation in the geriatric lung cancer patients. Thoracoscopic lobectomy without tracheal intubation during anesthesia is a valid alternative for managing selected geriatric patients with non-small cell lung cancer.
