Indications for treatment included rupture in 6(13%), hemathorax with impending rupture in 27(60%), malperfusion syndrome in 11(22%), and transient paraplegia in one patient (2.2%). Five kinds of commercially available thoracic stentgrafts were used. Follow up was 100% during a period of 13 months this website (range, 1-36 months).
Results: Technical success (coverage of the primary tear site) was achieved
in all 45 patients(100%) including deliberate partial or total coverage of the LSA in 7 patients (15.6%). The 30-day and in-hospital mortality was 4.4% including one late rupture case. Overall survival was 95.6% at 1 and 3-years’ follow-up. None of the patients with malperfusion required adjunct distal
stents All hemothoces resolved within 3 months including 5 patient required thoracentesis and one had tube thoracostomy. And 7 patients required temporary dialysis In-hospital complications occurred in 26.7% of patients and re-intervention was required in one patient and no patient had postoperative paraplegia Postoperative CT angiography showed find more 25 patients (58.1%) with complete thrombosis of the false lumen and re-expansion of the true lumen.
Conclusions: Endovascular repair of complicated acute type B aortic dissection with stentgraft is proven to be a technically feasible and effective in this relatively difficult patient cohort, The short and mid-term efficacy are persuasive, however, the long-term efficacy needs to be evaluated further.

“The recalcitrance in grasses varies according to cell type and maturation.
The origin of the recalcitrance in different regions from sugar cane internodes with varied lignin contents was evaluated. The efficiency of enzymatic hydrolysis was correlated with the chemical, micromorphological and microspectrophotometric characteristics of the samples. The internodes of three sugar cane hybrids were dissected into four different fractions. The outermost fraction and the rind were the most recalcitrant regions, whereas the pith-rind interface and the pith were less recalcitrant. Cellulose conversion reached 86% after 72 h of enzymatic digestion of the pith from the hybrid with the lowest lignin content. There was an inversely proportional correlation between the area occupied by vascular bundles and the efficiency of cellulose hydrolysis. High cellulose and low lignin or hemicellulose contents enhanced the efficiency of enzymatic hydrolysis of the polysaccharides. The critical evaluation of the results permitted to propose an empirical parameter for predicting cellulose conversion levels that accounts for the positive effect of high cellulose and low lignin plus hemicellulose and the detrimental effect of abundant vascular bundles.
