Observational StudyClinical outcomes and fate of the distal aorta following 1-stage repair of extensive chronic thoracic aortic dissection.
To analyze clinical outcomes and distal segmental aortic growth and aortic reoperation rates following 1-stage open repair of extensive chronic aortic dissection that included resection and graft replacement of the aneurysmal descending thoracic aorta. ⋯ Our extended experience with the 1-stage procedure confirms its safety and feasibility for treatment of extensive chronic thoracic aortic dissection. It is associated with a low incidence of reoperation on the contiguous aorta for aneurysmal degeneration. It represents a viable alternative to 2-stage and hybrid procedures that are also used to treat this condition.

Original rat model of high kinetic unilateral pulmonary hypertension surgically induced by combined surgery.
The characteristic morphologic lesions observed in the lungs of patients with congenital cardiac anomalies have not been closely modeled in rat shunt-related models, except for the reversible grade 1 changes. The present study reported an original rat model of unilateral pulmonary hypertension surgically induced by combined surgery to reproduce more advanced pulmonary vascular lesions. ⋯ The present shunt-related model successfully simulated a hypertensive status in pulmonary circulation and reproduced the characteristic transition of pulmonary vasculopathy from reversibility to irreversibility within a relatively short period. Thus, this model could offer an alternative with low mortality and high reproducibility for investigations on the underling mechanisms of shunt-related pulmonary hypertension.
