ObjectiveTo explore the effectiveness of transplantation of engraved autologous costal cartilage for individualized surgical management in secondary rhinoplasty for cleft lip. MethodsBetween September 2009 and January 2014, 350 patients with secondary nasal deformity of cleft lip were treated, including 160 males and 190 females with a mean age of 18.2 years (range, 16-56 years). Nasal deformity was caused by unilateral cleft lip in 200 cases and by bilateral cleft lip in 150 cases. The interval of lip repair and nasal deformity correction was 2-50 years (mean, 12 years). About a 2-6 cm cartilage was harvested from the 6th or 7th costal cartilage, and was engraved to the shape of "ge" in Chinese. The upper part was strengthened on both sides of the alar cartilage; the lower part was fastened to columella and nasal septum cartilages. The rest of cartilages was diced into 0.1 mm×0.1 mm×0.1 mm cubes. The columella incision was designed to "Z"-plasty, and was stretched to the nasion along alar edge. The engraved autologous costal cartilage was transplanted and fixed to the collapse of nostril. The cartilage cube was transplanted and filled into the collapse of nasal root to achieve the aesthetic effect of nasal augmentation. The effectiveness was evaluated according to the grade of secondary rhinoplasty for cleft lip by ZHANG Li et al. at 1, 6, and 12 months after operation. ResultsAll incisions were primary healing. All patients were followed up 1-12 months (mean, 6 months). After rhinoplasty, the collapse of nostrils was lifted, and the shape and height of collapse of nostrils were symmetrical to normal side. The deflection of columella nasi was corrected. A beautiful shape of nose was achieved. The excellent and good rates were 98.6% at 1 month, 97.4% at 6 months, and 97.1% at 12 months after operation, showing no significant difference (χ2=0.545, P=0.761). ConclusionThe technique of transplantation of engraved autologous costal cartilage for individualized surgical management in secondary rhinoplasty for cleft lip can achieve excellent surgery effect.
Objective To summarize the experiences of the surgical management for adult patients with aortic coarctation. Methods Clinical data of 40 adult patients diagnosed with aortic coarctation undergoing surgical repair in our center between July 2004 and March 2015 were retrospectively analyzed. There were 28 males and 15 females with a mean age of 26.3±11.0 years (ranging 16-57 years). We evaluated the effect of surgery by the change of pressure gradient between upper limb and lower limb, mechanical ventilation time, and length of ICU stay and hospital stay. Results Forty surgeries were finished successfully. One patient died after surgery. The follow-up ranged from 12 to 36 months. The mean pressure gradient reduced significantly after surgery. There were 6 patients suffering blood hypertension at their discharge, and all of them still need antihypertensive drugs. Conclusion Surgical repair is an effective treatment for adult with aortic coarctation. Extra-anatomic ascending-to-descending aortic bypass and concomitant repair of intracardiac anomalies is safe and effective.
Objective To retrospectively reviewed our experience of the surgical and perioperative treatment of patients suffering from critical Marfan syndrome with severe left ventricular dysfunction and to evaluate its therapeutic effect and prognosis. Methods Between January 2012 and October 2016, 15 patients diagnosed with Marfan syndrome combined with severe left ventricular dysfunction (left ventricular ejection fraction≤40% or left ventricular end diastolic diameter≥75 mm) underwent operations for aortic root aneurysm in Zhujiang Hospital and Guangdong General Hospital. Among them, 11 were males and 4 were females with a mean age of 32.9±8.7 years ranging from 19 to 55 years. Five patients with aortic dissection underwent Bentall procedure and total arch reconstruction with stent graft implantation. Two patients underwent Bentall procedure and hemi-arch replacement, seven patients underwent Bentall procedure and one patient underwent Cabrol procedure. Concomitant procedures included mitral valve repair in 12 patients, mitral valve replacement in 3 patients and tricuspid valve repair in 12 patients. Results There were 11 patients (73.3%) receiving intra-aortic balloon pumping implantation. One (6.7%) in-hospital death occurred. The left ventricular end diastolic diameter decreased from 80.5±7.4 mm to 58.3±6.0 mm (P<0.05) and the left ventricular ejection fraction improved from 37.3%±5.2% to 46.3%±4.4% 3 months postoperatively (P<0.05). The left ventricular end diastolic diameter decreased from 80.5±7.4 mm to 53.7±3.6 mm (P<0.05) and the left ventricular ejection fraction improved from 37.3%±5.2% to 57.7%±4.2% after one year (P<0.05). No death and reoperation occurred in the follow-up. Conclusion Although the patients with Marfan syndrome and severe left ventricular dysfunction usually have a high surgical mortality, the key to satisfactory outcomes of severe Marfan syndrome is adequate preoperative preparation, complete correction of all vascular lesions during the operation, application of circulatory auxiliary device and perioperative strict and long-term ICU monitoring.
