Objective: Hospitals throughout Japan are being integrated and reorganized under the government's regional medical care plan. However, the effects on cardiovascular surgery practice remain unknown. In the year 2016, our institution employed hospital integration; we report its effects on patients with type A acute aortic dissection who underwent emergency surgery. Methods: This study included 89 patients who underwent emergency surgery for type A acute aortic dissection from May 2012 to December 2020. Evaluation items included preoperative patient factors, number of surgeries, surgical mortality, referral rate, patient transport time, transport distance, number of surgeries performed by young cardiovascular surgeons, and overtime work for surgery. Patients were categorized into pre-(group P: 29 patients) and post-integration (group A: 60 patients) groups, which were retrospectively compared. Results: Preoperative factors were not significantly different between the two groups. Operations accounted for 29 and 60 in groups P and A, respectively; they increased significantly after integration (p=0.005). Surgical mortality was 27.6 and 15% in groups P and A, respectively, with no significant difference (p=0.2). The referral rate was 17 (58.6%) and 21 (35%) patients in groups P and A, respectively; group A displayed a significantly lower referral rate (p=0.04). The interval from the onset of symptoms to arrival at the surgery cite was significantly reduced (p=0.01) in group A (112±140 min) compared to group P (206±201 min). There was no significant difference in the transfer distance between groups P (13.9±14.8 km) and A (13.5±16.2 km). The number of surgeries performed by young surgeons increased in 9 cases (31%) in group P and 34 cases (56.7%) in group A (p=0.02). Overtime work was substantially reduced:446±154 min in group P and 349±112 min in group A. Conclusion: Hospital integration resulted in increased number of acute aortic dissection surgeries and decreased interval time from the onset of symptoms to arrival at the surgery cite. The young surgeons performed more surgeries and reduced their overtime work.

A 60-year-old man underwent open surgery for chronic dissecting abdominal aorta accompanied with a horseshoe kidney. Through open laparotomy, the abdominal aortic aneurysm was exposed without revision of the horseshoe kidney. Cold ringer solution was infused to accessory renal arteries for renal protection. After supra-renal clamping, proximal anastomosis was then performed at the level just below the renal arteries. Abdominal cross clamp time at the level of the supra-renal arteries was 23 min. Median and right accessory arteries were reattached with an ischemic time of 73 and 103 min, respectively. Although serum creatine was elevated a preoperative level of 1.17 mg/dl to 3.63 mg/dl at postoperative day 2, that was gradually decreased to nearly preoperative level of 1.25 mg/dl at discharge. Postoperative enhanced CT demonstrated patency of the reattached accessory arteries. The patient was discharged without major complication on postoperative day 21. One year postoperatively, his follow-up course was uneventful without deterioration of renal function.

BACKGROUND: To examine changes in psychological distress prevalence among pregnant women in Miyagi Prefecture, which was directly affected by the Great East Japan Earthquake and tsunami, and compare it with the other, less damaged areas of Japan. METHODS: This study was conducted in conjunction with the Japan Environment and Children`s Study. We examined 76,152 pregnant women including 8270 in Miyagi Regional Center and 67,882 in 13 other regional centers from the all-birth fixed data of the Japan Environment and Children's Study. We then compared the prevalence and risk of distress in women in Miyagi Regional Center and women in the 13 regional centers for 3 years after the disaster. RESULTS: Women in the Miyagi Regional Center suffered more psychological distress than those in the 13 regional centers: OR 1.38 (95% CI, 1.03-1.87) to 1.92 (95% CI, 1.42-2.60). Additionally, women in the inland area had a consistently higher prevalence of psychological distress compared to those from the 13 regional centers: OR 1.67 (95% CI, 1.18-2.38) to 2.19 (95% CI, 1.60-2.99). CONCLUSIONS The lack of pre-disaster data in the Japan Environment and Children's Study made it impossible to compare the incidence of psychological distress before and after the March 2011 Great East Japan Earthquake. However, 3 years after the Great East Japan Earthquake, the prevalence of pregnant women with psychological distress did not improve in Miyagi Regional Center. Further, the prevalence of mental illness in inland areas was consistently higher than that in the 13 regional centers after the disaster.
