This series consists of a 12-year experience with a policy of identifying and replacing the aortic segment containing the primary intimal tear for repair of acute aortic dissection. ⋯ Systematic resection of the primary tear yielded similar hospital mortality, 5-year survival, and aorta-related event-free survival rates for subtypes of acute type A dissection. Excellent results were obtained with a selective approach to type B dissection.

The aim of the present study was to verify the efficacy of preserving the aortic valve in patients with acute type A aortic dissection complicated by significant aortic regurgitation. ⋯ Preservation of the aortic valve and aortic root is recommended in patients with acute type A aortic dissection and absent or mild aortic insufficiency. Patients presenting with moderate-to-severe aortic regurgitation and treated conservatively present an increased risk of recurrent valvular insufficiency.

We report novel techniques of performing bidirectional Glenn shunt (BDG) without cardiopulmonary bypass (CPB). ⋯ Our technique provides an excellent venous drainage with improvement of O2 saturation during SVC clamping. It avoids problems related to CPB and economy. It is easily reproducible, with excellent results in a selected group of patients without compromising the completeness of repair.

N1 disease represents a heterogeneous group of non-small cell lung carcinoma with varying 5-year survival rates. Specific types of N1 lymph node involvement need to be further investigated and their prognostic significance clarified. ⋯ N1 disease is a compound of two subgroups: one located inside the lobes is related to N0, and the other (extralobar or hilar) behaves like an early stage of N2 disease. This offers further information for clinical, therapeutic, and research purposes.

Patients with aortic valve disease and aneurysm or dilatation of the ascending aorta require both aortic valve replacement and treatment of their ascending aortic disease. In children and young adults, the Ross operation is preferred when the aortic valve requires replacement, but the efficacy of extending this operation to include replacement of the ascending aorta or reduction of the dilated aorta has not been tested. ⋯ Early results with extension of the Ross operation to include replacement of an ascending aortic aneurysm or vertical aortoplasty for reduction of a dilated ascending aorta are excellent, with autograft valve function equal to that seen in similar patients without ascending aortic disease.
