The aim of this study is to identify the predictors of hospital readmission or early unplanned return to clinic within 30 days of discharge after pulmonary lobectomy. ⋯ Patients who require a postoperative transfer to the intensive care unit or with higher Charlson comorbidity index are at higher risk for hospital readmission after pulmonary lobectomy. Readmission was not affected by the surgical approach. Whether a different strategy to follow-up for these high-risk patients can prevent readmission remains to be determined.

Benign tracheal stenosis complicates tracheal intubation or tracheostomy in 0.6% to 65% of cases. Surgical resection is the standard treatment. Endoscopic management is used for inoperable patients with 17% to 69% success. Dynamic "A-shape" tracheal stenosis (DATS) results in a dynamic stenosis with anterior fracture of tracheal cartilage and frequently associated posterior malacia. We report the results of our multidisciplinary management. ⋯ The DATS management was successful in 63%. Stent migration was frequent. Posterior tracheomalacia was successfully treated in selected cases, avoiding stent placement.

Multicenter Study Comparative Study
Ministernotomy versus full sternotomy aortic valve replacement with a sutureless bioprosthesis: a multicenter study.
The aim of this study was to analyze early postoperative outcomes and 2-year survival after aortic valve replacement (AVR) with the sutureless Perceval bioprosthesis (Sorin Biomedica Cardio Srl, Salluggia, Italy) performed through ministernotomy compared with full sternotomy. ⋯ AVR with the sutureless Perceval bioprosthesis through a ministernotomy was a safe and reproducible procedure that was not associated with prolonged aortic cross-clamp or cardiopulmonary bypass time compared with a full sternotomy. Early postoperative outcomes and 2-year survival were comparable between patients undergoing ministernotomy and full sternotomy.

Recent studies have focused on the use of fixed-rate intraaortic balloon pumping (IABP) during cardiopulmonary bypass (CPB) to achieve pulsatile flow. Because application of an IABP catheter may represent a functional obstruction within the descending aorta, we explored the effect of IABP-pulsed CPB-perfusion with special attention to perfusion above and below the IABP balloon. ⋯ Using IABP as a surrogate to achieve pulsatile perfusion during CPB contributes significantly to lowered aortic pressure in the distal portion of aorta and impaired tissue perfusion of the kidneys. The results are focusing on effects that may contribute to organ dysfunction and acute kidney injury. Consequently, assessment of perfusion pressure distal to the balloon should be addressed whenever IABP is used during CPB.
