Acute type A aortic dissection surgery in retrosternal gastric tube reconstruction patient.

BACKGROUND: Retrosternal gastric tube reconstruction is a common surgical technique for managing esophageal cancer, but it complicates acute type A aortic dissection repair and raises concerns about gastric tube damage. CASE PRESENTATION: A 73-year-old female, who underwent esophagectomy with retrosternal gastric tube reconstruction 6 months ago for esophageal cancer, presented with severe chest pain. Acute type A aortic dissection was confirmed by contrast-enhanced computed tomography, and emergency hemiarch replacement through a median sternotomy was performed, preserving the gastric tube without injury. The patient recovered well and was discharged after 3 weeks, showing no gastrointestinal symptoms or signs of mediastinitis.

Aortoesophageal fistula treated using one-stage total reconstruction: a case report from a high-volume center.

BACKGROUND: Aortoesophageal fistula (AEF) is a rare but typically life-threatening condition. Although several treatment strategies exist, including conservative treatment with intraluminal stent graft and open thoracic aortic replacement, the overall outcome remains poor, ranging from 16 to 39%. Furthermore, esophageal reconstruction methods vary between hospitals. Herein, we report a case of aortoesophageal fistula treated using one-stage total reconstruction. CASE PRESENTATION: This case involved a 58-year-old woman who developed acute type A aortic dissection and underwent successful total arch replacement at the other hospital. However, she developed AEF 1 year later and underwent urgent thoracic endovascular aortic repair, which eventually failed. We performed thoracic aortic replacement, total esophagectomy, gastric tube reconstruction, and omental flap in a one-stage operation. The patient was extubated the next day and transferred to the general ward on postoperative day 3. Computed tomography revealed favorable results. CONCLUSIONS: For postoperative AEF, dedicated debridement with reconstruction is more effective than conservative treatment. In an experienced center, post-procedure-related AEF can be easily treated using one-stage reconstruction.

Open after endovascular repair for previous extra anatomic bypass of adult coarctation.

BACKGROUND: During follow-up, aneurysm formation in adults with coarctation of aorta has been reported after undergoing extra-anatomical aortic bypass grafting. Endovascular repair was a reasonable treatment option but there were still complications. CASE PRESENTATION: A 48-year-old male who underwent extra-anatomical aortic bypass grafting, presented with severe back pain and hemoptysis. He had a diagnosed pseudoaneurysm with concealed rupture at the bypass grafting. He underwent endovascular repair and coil embolization. A postsurgical CT-angiogram showed there was extravasation from stent into the pseudoaneurysm. An open repair with endovascular stent removal instead of restenting was performed.

Descending thoracic aortic repair outcomes for chronic aortic dissection: a single-centre experience.

OBJECTIVES: Thoracic endovascular aortic repair is a widely accepted treatment for chronic aortic dissection because of good early results compared to open surgical repair. We provide early and long-term results of descending thoracic aortic repair for chronic aortic dissection. METHODS: Patients who underwent descending thoracic aortic repair for chronic aortic dissection between January 2012 and December 2020 at Kawasaki Aortic Centre were included in this analysis. RESULTS: Four hundred ninety-two patients (median age, 64 years; interquartile range, 52-75 years) were included. The median duration of follow-up was 3.2 years (interquartile range, 1.5-5.2 years). The early mortality rate was 2.0% (n = 10); strokes occurred in 17 patients (3.5%); and spinal cord injuries occurred in 30 patients (6.1%). Early major adverse events including early death, stroke, spinal cord injury, tracheostomy and haemodialysis at the time of discharge occurred in 62 patients. Multivariable analysis indicated that age > 70 years and non-elective surgery were predictors of early major adverse events. Among patients without both risk factors (i.e. low-risk patients), 1 early death (0.4%), 3 strokes (1.5%) and 1 spinal cord injury (0.4%) were observed, 2 tracheostomies were performed (0.8%) and no patients required haemodialysis at the time of hospital discharge. The 5-year survival rate was 87.2%. The cumulative incidence of chronic aortic dissection-related aortic reintervention at 5 years was 7.9%. CONCLUSIONS: Descending thoracic aortic repair for chronic aortic dissection resulted in good early and long-term results, and it can serve as the gold standard for low-risk patients.

Open Thoracoabdominal Aortic Aneurysm Repair: Contemporary Outcomes for 393 Elective Cases.

BACKGROUND: The purpose of this study was to reveal the midterm and long-term mortality rates among patients with thoracoabdominal aortic aneurysm (TAAA) after open TAAA repair and to clarify the effect of aneurysm type on mortality. METHODS: We retrospectively analyzed data for 393 patients (290 men; age, 63.2 ± 12.7 years) who underwent open TAAA repair of elective Crawford extent I, II, or III TAAAs (62, 197, and 134 patients, respectively) between June 2003 and December 2015. The overall survival probability and differences according to aneurysm type were assessed using the Kaplan-Meier product limit method. Also, the effect of aneurysm type on mortality was assessed using the hazard ratio and Cox proportional hazards regression. RESULTS: The overall survival probabilities at 3 months, 1 year, 5 years, and 10 years were 90%, 84%, 78%, and 75%, respectively. The age-adjusted relative mortality rate was significantly higher for patients with dissecting aneurysms than for those with nondissecting aneurysms (relative risk, 1.62; 95% confidence interval, 1.03 to 2.55). In the multivariate Cox proportional hazard regression model, the hazard ratio for all-cause mortality did not differ between patients with dissecting and those with nondissecting aneurysms. However, those with dissecting aneurysms had increased mortality rates as their percentage vital capacity decreased (hazard ratio, 0.7; 95% confidence interval, 0.5 to 1.0); a similar trend was not observed for those with nondissecting aneurysms. CONCLUSIONS: Open TAAA repair can be safely performed with acceptable midterm and long-term results. Poor pulmonary function can impair the survival outcome of patients with dissecting aneurysms.

Surgical outcomes of aortic repair via transapical cannulation and the adventitial inversion technique for acute Type A aortic dissection.

OBJECTIVES: To evaluate the surgical outcomes of aortic repair via transapical cannulation and the adventitial inversion technique for acute Type A aortic dissection. METHODS: Between 2008 and 2015, a total of 300 patients with acute Type A aortic dissection underwent emergency surgery, consisting of 271 hemiarch repairs and 29 total aortic arch replacements, using transapical cannulation and the adventitial inversion technique at a distal anastomosis. The mean follow-up periods were 31.7 ± 25.2 months. Overall, 18% (54/300) of the patients were octogenarians, and 21.7% (65/300) had cardiac tamponade; 25% (75/300) had preoperative malperfusion. RESULTS: The in-hospital and 30-day mortality rates were 8.3% (25/300) and 6.7% (20/300), respectively. The 30-day mortality rate was 2.7% (6/225) among patients without preoperative malperfusion and 18.7% (14/75) among patients with malperfusion (P < 0.0001), 7.4% (4/54) among octogenarians and 6.5% (16/246) among patients aged less than 80 years (P = 0.81), and 6.3% (17/271) among patients treated with hemiarch repair and 10.3% (3/29) among patients treated with total aortic arch replacement (P = 0.403). Preoperative malperfusion was an independent predictor of perioperative mortality in a multivariable analysis. During the follow-up period, distal reintervention was performed in 11% (33/300) of the patients. The rates of freedom from reintervention at 1, 3 and 5 years were 95.9%, 88.9% and 80.0%, respectively. The overall survival rates at 1, 3 and 5 years were 88.7%, 86.7% and 82.0%, respectively. The in-hospital mortality rate for elective reintervention was 3.0% (1/33). CONCLUSIONS: Aortic repair via transapical cannulation and the adventitial inversion technique for acute Type A aortic dissection provides good early and mid-term results. The safety of elective distal reintervention can be guaranteed. To obtain better operative outcomes, effective treatment for cases with malperfusion is mandatory.
