  • Surgical management for 40 adult patients with aortic coarctation

    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.

  • Curative effect analysis of Sun’s procedure for acute or chronic Stanford A aortic dissection: A case control study

    Objective To analyze the surgical effect of total aortic arch replacement and stented elephant trunk (Sun’s procedure) for acute or chronic Stanford type A aortic dissection, and to investigate the optimal surgical timing for Stanford type A aortic dissection involving aortic arch. Methods We retrospectively reviewed the clinical data of 327 patients with acute or chronic Stanford type A aortic dissection treated by Sun's procedure from June 2010 to June 2014 in Guangdong Cardiovascular Institute. Patients were divided into two groups according to whether the time from onset to operation was longer than 2 weeks: an acute group with 229 patients (≤2 weeks, the average time of onset to operation 5.70±3.50 d) and a chronic group with 98 patients (>2 weeks, the average time of onset to operation 21.60±15.70 d). There were 186 males and 43 females with a mean age of 47.47±11.19 years in the acute group, and 76 males and 22 females with a mean age of 45.62±12.92 years in the chronic group. The patients discharged from hospital were followed up for one year. Results There was no significant difference between the two groups in preoperative data. The rate of coronary artery bypass grafting, cardiopulmonary bypass time, aortic cross-clamping time, intraoperative and postoperative 24 h red blood cell intake were higher or more in the acute group than those in the chronic group (P<0.05). The in-hospital morality, ICU stay, mechanical ventilation time, the incidence of neurological dysfunction, low cardiac output syndrome, acute renal failure with continuous renal replacement therapy, hepatic insufficiency, poor wound healing were higher or more in the acute group than those in the chronic group (P<0.05). During one year follow-up, the survival rate of the acute and chronic groups was 97.0% and 97.6% respectively (P>0.05). No new complications were found in the two groups. The irreversible neurological dysfunction, paraplegia and renal failure showed no significant difference between the two groups. Conclusion The short-term mortality and complications of acute Stanford A aortic dissection involving aortic arch treated by Sun’s procedure are significantly higher or more than those of chronic Stanford type A aortic dissection. The risk of surgical treatment in acute phase is high.

  • Surgical versus conservative treatment for acute type A aortic intramural hematoma: A retrospective cohort study

    ObjectiveTo compare the outcomes following emergency surgery or conservative treatment for patients with acute type A aortic intramural hematoma (IMH).MethodsClinical data of consecutive patients diagnosed with acute type A aortic IMH in our hospital from September 2014 to December 2018 were retrospectively analyzed. The patients who met our surgical indications received surgery (an operation group) and other patients received strict conservative treatment (a conservative treatment group).ResultsFinally 127 patients were enrolled, including 112 males and 15 females with an average age of 53.6±13.0 years. Of 127 patients, 85 (66.9%) patients accepted emergency surgery and 42 (33.1%) patients accepted strict conservative treatment. There was no difference between the two groups in early mortality or complications (P>0.05). The 5-year survival rate was 90.4% in the operation group and 74.3% in the conservative treatment group (P=0.010). A maximum aortic diameter in the ascending aorta and aortic arch≥45 mm and maximum thickness of IMH in the same section≥8 mm were risk factors for IMH-related death in patients undergoing conservative treatment (P<0.001).ConclusionThe mortality associated with emergency surgery for patients with acute type A aortic IMH is satisfactory. In clinical centers with well-established surgical techniques and postoperative management, emergency surgical treatment may provide a better outcome than conservative treatment for patients with acute type A aortic IMH.
