Potts shunt in children with idiopathic pulmonary arterial hypertension: long-term results.
Idiopathic pulmonary arterial hypertension (IPAH) remains a progressive fatal disease. Palliative Potts shunt has been proposed in children displaying suprasystemic IPAH. ⋯ Palliative Potts shunt constitutes a new alternative to lung transplantation in severely ill children with suprasystemic IPAH, carrying a prolonged survival and persistent improvement in functional capacities.

Inhaled nitric oxide plus iloprost in the setting of post-left assist device right heart dysfunction.
Pulmonary hypertension and right ventricular (RV) dysfunction may complicate the implantation of a left ventricular assist device (LVAD). We examined whether inhaled vasodilators can sufficiently reduce RV afterload, avoiding the need for temporary RV mechanical support. ⋯ Inhaled vasodilators mainly affected the pulmonary vasculature. Combination treatment with inhaled NO and iloprost sufficiently decreased PVR and MPAP on the basis of an additive effect, improved RV function, and avoided the need for RV assist device.

Recent literature suggests that a restrictive approach to red blood cell transfusions is associated with improved outcomes in cardiac surgery patients. Even in the absence of bleeding, intravascular fluid shifts cause hemoglobin levels to drift postoperatively, possibly confounding the decision to transfuse. The purpose of this study was to define the natural progression of hemoglobin levels in postoperative cardiac surgery patients. ⋯ In this report of hemoglobin drift after cardiac surgery, although all postoperative patients experienced downward hemoglobin drift, 79% of patients exhibited hemoglobin recovery before discharge. Physicians should consider the eventual upward hemoglobin drift before administering red blood cell transfusions.

Robotic anatomic segmentectomy of the lung: technical aspects and initial results.
Robotic lobectomy with radical lymph node dissection is a new frontier of minimally invasive thoracic surgery. Series of sublobar anatomic resection for primary initial lung cancers or for metastasis using video-assisted thoracic surgery have been reported but no cases have been so far reported using the robot-assisted approach. We present the technique and surgical outcome of our initial experience. ⋯ Robotic anatomic lung segmentectomy is feasible and safe procedure. Robotic system, by improving ergonomic, surgeon view and precise movements, may make minimally invasive segmentectomy easier to adopt and perform.

Characteristics associated with the use of nonanatomic resections among Medicare patients undergoing resections of early-stage lung cancer.
Racial disparities in access to surgical resection for treatment of early-stage non-small-cell lung cancer (NSCLC) are well documented. However it is unclear how race, clinical, and hospital characteristics affect the surgical approach among patients undergoing resection. ⋯ Since 2000, the use of nonanatomic resections in stage I NSCLC has increased, most significantly among patients with larger tumors. After adjusting for clinical factors, there was no relation between race and type of surgical resection.
