ABSTRACT

Objective:To summarize the clinical data of Sun's procedure(total aortic arch replacement with frozen elephant trunk technique) in the treatment of complex aortic arch disease after previous cardiac surgery.Methods:From January 1, 2018 to December 31, 2020, a total of 55 patients underwent resternotomy Sun's procedure in the Aortic Surgery Center of Beijing Anzhen Hospital, including 41 males and 14 females, with a mean age of(45.4±12.7) years old, were retrospectively analyzed. The indications of primary cardiac surgery included type A aortic dissection, aortic root or ascending aortic aneurysm, heart valve surgery, and coronary heart disease. Indications for reoperation included residual aortic dissection larger than 55 mm in diameter, aortic aneurysm dilation, new type A aortic dissection, anastomotic leakage with symptoms, and pseudoaneurysm. All the operations were performed under general anesthesia and median resternotomy, total aortic arch replacement with the stented elephant trunk implantation and were performed by anterograde unilateral or bilateral cerebral perfusion.Results:There was no intraoperative death, and the postoperative mortality was 9.1%(5/55). The causes of death were 2 cases of low cardiac output, 1 case of respiratory failure, 1 case of cerebral complications, and 1 case of gastrointestinal bleeding. Except death, there were 2 cases of postoperative cerebral complications(2/50, 4%), 5 cases of spinal cord injury(transient paraplegia)(5/50, 10%), the median duration of ventilator use was 17 hours(14-42 h). Other postoperative complications included respiratory insufficiency requiring ventilatory support longer than 48 hours(8/50, 16%), renal insufficiency requiring temporary dialysis(2/50, 4%). The follow-up time was(25.9±11.2) months(10-47 months), during which 1 case died due to cerebral complication, 4 cases underwent total thoracoabdominal aorta replacement, and 1 case underwent anastomotic leakage repair.Conclusion:It is safe and effec to perform Sun's procedure(total aortic arch replacement with frozen elephant trunk technique) in the treatment of complex arch disease after previous cardiac surgery.

ABSTRACT

@#Objective    To discuss the efficacy of type Ⅱ hybrid aortic arch repair for type A aortic dissection in patients of different age groups. Methods    We retrospectively analyzed the clinical data of 126 patients with type A aortic dissection admitted to the Fuwai Hospital between January 2016 and December 2018, including 78 (61.9%) males and 48 (38.1%) females, with an average age of 61.8±6.9 years. The patients were divided into an elderly group (≥60 years, n=82) and a non-elderly group (<60 years, n=44). The preoperative, intraoperative and postoperative data of patients in the two groups were compared. Results    The age between the elderly and non-elderly group was significantly different (65.9±4.1 years vs. 54.3±4.1 years, P<0.010), and no significant difference was found between the two groups in other preoperative baseline data. There were 6 (4.8%) patients of early death, 3 (2.4%) patients of stroke and 2 (1.6%) patients of paralysis. A total of 194 stents were implanted, and the average dimeter of the stents was 33.6±1.8 mm and the average length was 199.0±6.7 mm. The non-elderly group had shorter mechanical ventilation time (31.9±41.7 h vs. 61.0±89.2 h, P=0.043) and ICU stay time (77.8±51.4 h vs. 143.1±114.4 h, P<0.001) than the elderly group. There was no significant difference in in-hospital mortality rate, reoperation rate or survival rate between the two groups (P>0.05). Follow-up time was 1-43 (22.6±10.8) months, and 3 patients were lost. There were 104 (82.5%) patients of complete thrombus formation of false lumen in stent and endoleak was reported in 11 (9.2%) patients. Conclusion    Type Ⅱ hybrid aortic arch repair offers an alternative approach to acute type A aortic dissection with acceptable early and mid-term clinical effects. The non-elderly patients have a similar early treatment effect to the elderly patients, but have a better mid-term outcome.

ABSTRACT

We report a rare case of paraplegia after emergency total arch replacement for type A acute aortic dissection. A 52-year-old man was referred to our hospital for acute aortic dissection. Contrast-enhanced computed tomography showed a type A aortic dissection extending from the aortic root into the right iliac arteries. The true lumen of the descending and abdominal aorta was collapsed and blood flow to the right lower limb had decreased. Large entry and re-entry tears were revealed in the ascending and distal arch aorta, respectively. His preoperative consciousness was clear, hemodynamics were stable, and there was no evidence of paraplegia or paraparesis. Extracorporeal circulation was established by femoral artery and right atrium cannulation. Total arch replacement was performed under moderate hypothermic circulatory arrest (lowest bladder temperature : 21.9°C). The postoperative course was uneventful and he was extubated 6 h postoperatively. Postoperative hemodynamic parameters were stable, the mean blood pressure was maintained at around 70 mmHg, and limb movements were confirmed at that time. Although there was no abnormality of lower limb movement until the following morning, paraplegia occurred about 17 h after surgery. While maintaining a mean blood pressure of over 90 mmHg, urgent cerebrospinal drainage was immediately performed and combined with steroid treatment and a continuous infusion of naloxone. The neurological defect was resolved immediately after cerebrospinal drainage, and neurological function steadily improved through rehabilitation. He was discharged 20 days after surgery with no neurological defects. Late paraplegia after total replacement for type A acute aortic dissection is a rare complication. From our experience, it is suggested that early diagnosis and treatment are important for improving paraplegia.

ABSTRACT

A 76-year-old man with a history of total esophagectomy and retrosternal gastric tube reconstruction for esophageal cancer was transferred to our hospital because of consciousness disorder. It became an emergency operation on diagnosis of Stanford type A acute aortic dissection on enhanced CT. Because CT showed the retrosternal gastric tube ran along the right side of the body of the sternum through the back side of the manubrium, we opted for skin and the suprasternal incision on the left side from center. We could perform total aortic arch replacement without the damage of the gastric tube except that the right side of the operative view was slightly poor. We did not recognize digestive organ symptoms such as postoperative passage disorders nor mediastinitis. The patient was discharged from our hospital on postoperative day 24.

ABSTRACT

Objective To observe the operative outcomes of Marfan's syndrome.Methods Collecting 32 cases of Marfan's syndrome operated in our hospital and analyzing the changes of cardiac function between preoperation and 6~12 months postoperation. Results There were 29 cases of Bentall(replacement of the ascending aortic with flap valve canal) operation, 3 cases of them were Bentall with total aortic arch replacement; two case were replaced the mitral valve in the homochronous operation; 3 cases died from the Bentall operation,other 3 cases were lost to follow up. The size of left ventricle(LV), left ventricular ejection fraction(LVEF), left ventricular end-diastolic volume index (LVEDVI) and left ventricular end-systolic volume index(LVESVI) were remarkable improved in postoperation. Conclusions Surgical treatment is an effective way for the cardiovascular lesions of Marfan's syndrome.
