OBJECTIVES The objective of the present study was to evaluate short- and mid-term outcomes of the left subclavian artery (LSA) chimney stent implantation (LSACSI) during thoracic endovascular aortic repair (TEVAR), and to summarize our experience with this technique. METHODS From June 2010 to September 2012, 59 patients (49 men; mean age of 57.4 ± 13.3(More)
This paper presents the design consideration of high order digital AZ modulators used as modulus controller for fractional-N frequency synthesizer. A third-order MASH structure (MASH 1-2) is designed and implemented which allows for the input to operate over 75% of the input adder capacity. The number of the output levels is reduced to two bits. The circuit(More)
OBJECTIVE To evaluate the efficacy of Fluoro Jade-C staining (FJC) in the assessment of brain injury after deep hypothermia circulatory arrest (DHCA). METHODS Six healthy adult miniature male pigs underwent DHCA, the rectal temperature was down to 18°C, circulation was stopped , circulatory arrest was maintained for 60 minutes. On postoperative day 1,(More)
OBJECTIVE In patients with acute type A dissection, it is controversial whether to use a more aggressive strategy with extended aortic replacement to improve long-term outcome or to use a conventional strategy with limited ascending aortic or hemiarch replacement to circumvent a life-threatening situation. METHODS Between April 2003 and June 2007, 107(More)
BACKGROUND The haplotypes in the gene vitamin K epoxide reductase complex subunit 1 (VKORC1) have been found to affect warfarin dose response through effects on the formation of reduced-form vitamin K, a cofactor for gamma-carboxylation of vitamin K-dependent proteins, which is involved in the coagulation cascade and has a potential impact on(More)
BACKGROUND Appropriate surgical management of type A dissection is a critical factor for achieving satisfactory outcome, but the choice of optimal procedure is controversial. We retrospectively reviewed our experience with aortic arch replacement for type A dissection involving the arch. METHODS AND RESULTS Excluding 14 cases of subtotal or total aortic(More)
OBJECTIVE Aortic aneurysm formation leading eventually to aortic rupture or dissection in early adult life is a fatal outcome of Marfan syndrome (MFS). Advances in the treatment of the syndrome have improved prognosis, but the long-term reoperation rate is still high. It remains unknown which factors influence the long-term prognosis, including the(More)
OBJECTIVES To eliminate the residual false lumen in the descending thoracic aorta and improve long-term outcomes of surgical intervention for Stanford type A aortic dissection, we performed the skeletonized "elephant trunk" procedure in the ascending aorta and aortic arch replacement combined with transaortic stented graft implantation into the descending(More)
OBJECTIVE The optimal surgical repair for patients with Marfan syndrome with type A dissection involving the aortic arch is controversial. We retrospectively reviewed our experience of total arch replacement combined with stented elephant trunk implantation for patients with Marfan syndrome with type A dissection. METHODS Between April 2003 and September(More)
BACKGROUND Significant advances in the diagnosis and therapy have greatly improved surgical outcomes of acute type A dissection. However, surgical management of acute type A dissection still poses formidable challenges, particularly in "developing" countries. We present our surgical management strategy of acute type A dissection in a single center in China.(More)
