Arterioureteral fistula is a rare but life-threatening condition. An endovascular treatment approach is commonly used; however, there is a potential risk of infection. We present a case in which a patient presented with abdominal pain and was diagnosed with a ruptured internal iliac artery aneurysm and a subsequent arterioureteral fistula. An aortic stent graft was inserted to treat the arterioureteral fistula, but it subsequently became infected, resulting in the patient's death. This case underscores the importance of early diagnosis and treatment of arterioureteral fistula and the possibility of graft infection.

Inferior vena cava (IVC) thrombosis, a type of deep vein thrombosis (DVT), is a relatively rare and poorly known disease compared to lower extremity DVT. We present a case of a 68-year-old woman with abdominal pain and mild lower leg swelling due to IVC thrombosis extending from the common iliac vein to the infrahepatic IVC. The thrombus was removed using a 14-mm Niti-S stent (Taewoong Medical, Korea) inserted via the right internal jugular vein. The stent was partially deployed and gently advanced to cover the thrombus, and then retracted through a vascular sheath capturing the thrombus. This case presents a therapeutic approach for the treatment of IVC thrombosis using a half-deployed stent as a filter and a basket. Follow-up evaluation after 5 years revealed a patent IVC and common iliac vein.

BACKGROUND AND OBJECTIVES: Increasing evidence supports that psychological factors may be related to development of coronary artery disease (CAD). Although psychological well-being, ill-being, and control strategy factors may play a significant role in CAD, rarely have these factors been simultaneously examined previously. We assessed comprehensive psychological factors in patients with acute coronary syndrome (ACS). SUBJECTS AND METHODS: A total of 85 ACS patients (56 unstable angina, 29 acute myocardial infarction; 52.6+/-10.2 years; M/F=68/17) and 63 healthy controls (48.7+/-6.7 years, M/F=43/20) were included. Socio-demographic information, levels of psychological maladjustment, such as anxiety, hostility, and job stress, health-related quality of life (HRQoL), and primary and secondary control strategy use were collected through self-report questionnaires. RESULTS: There was no significant difference between the ACS group and control group in levels of anxiety, hostility, and job stress. However, ACS patients had significantly lower scores on the general health perception and bodily pain subscales of HRQoL than the control group. The ACS group, as compared with the controls, tended to use primary control strategies more, although not reaching statistical significance by univariate analysis. Multivariate logistic regression analysis after adjusting age and gender identified the physical domain of HRQoL {odds ratio (OR)=0.40}, primary control strategy (OR=1.92), and secondary control strategy (OR=0.53) as independent predictors of ACS. CONCLUSION: Poor HRQoL and primary control strategy, proactive behaviors in achieving ones' goal, may act as risk factors for ACS, while secondary control strategy to conform to current situation may act as a protective factor for ACS.

A 57-year-old woman presented to vascular surgery clinic with visceral artery aneurysms that were incidentally detected during regular check-up. Imaging studies revealed occlusion of the celiac axis and severe stenosis of the superior mesenteric artery and 3 aneurysms along the posterior and inferior pancreaticoduodenal arteries, as well as the right gastroepiploic artery. Endovascular embolization of all aneurysms was rejected because of the risk of hepatic ischemia. These complicated lesion caused by polyarteritis nodosa were successfully treated using a hybrid operation with coil embolization, aneurysm resection, and antegrade aorto-celiac-superior mesentery artery bypass.

PURPOSE: The AFX2 endograft is a unibody, bifurcated stent graft that can be used to lower complications in certain patients. In this study, we retrospectively reviewed consecutive cases in which the AFX2 system was used to overcome the challenges of narrow distal aorta, as well as to reduce procedure time and contrast medium dose. Furthermore, we compared the results with matched patients treated using the Endurant II endograft system.MATERIALS AND METHODS: This was a retrospective observational study of nine patients with abdominal aortic aneurysm (AAA) who underwent endovascular aneurysm repair (EVAR) using the AFX2 device between June 2017 and April 2018 at Seoul National University Hospital. The patients had narrow distal aorta (n=3), reversed tapered neck (n=1), iliac artery aneurysm (n=2), chronic kidney disease patients (n=2), and impending rupture (n=1). Seven matched patients were treated using the Endurant II graft.RESULTS: In the AFX2 group, the mean procedure time was 87.2 minutes, mean blood loss volume was 157.7 mL, and mean volume of contrast medium used was 48.3 mL. In the Endurant II group, the mean procedure time was 140.0 minutes, mean blood loss volume was 175.0 mL, and mean volume of contrast medium used was 119.3 mL.CONCLUSION: Our preliminary experiences with selected AAA patients treated using the AFX2 endovascular repair system showed good outcomes compared with similar patients treated using the Endurant II system. Therefore, the AFX2 may be a good option to perform EVAR in patients of advanced age who have chronic kidney failure or narrow distal aorta.

Objectives:
The coronavirus disease 2019 (COVID-19) pandemic has led to a global shortage of medical resources; therefore, we investigated whether COVID-19 impacted the quality of non-COVID-19 hospital care in Korea by comparing hospital standardized mortality rates (HSMRs) before and during the pandemic.
Methods:
This retrospective cohort study analyzed Korean National Health Insurance discharge claim data obtained from January to June in 2017, 2018, 2019, and 2020. Patients’ in-hospital deaths were classified according to the most responsible diagnosis categories. The HSMR is calculated as the ratio of expected deaths to actual deaths. The time trend in the overall HSMR was analyzed by region and hospital type.
Results:
The final analysis included 2 252 824 patients. In 2020, the HSMR increased nationwide (HSMR, 99.3; 95% confidence interval [CI], 97.7 to 101.0) in comparison to 2019 (HSMR, 97.3; 95% CI, 95.8 to 98.8). In the COVID-19 pandemic zone, the HSMR increased significantly in 2020 (HSMR, 112.7; 95% CI, 107.0 to 118.7) compared to 2019 (HSMR, 101.7; 95% CI, 96.9 to 106.6). The HSMR in all general hospitals increased significantly in 2020 (HSMR, 106.4; 95% CI, 104.3 to 108.5) compared to 2019 (HSMR, 100.3; 95% CI, 98.4 to 102.2). Hospitals participating in the COVID-19 response had a lower HSMR (HSMR, 95.6; 95% CI, 93.9 to 97.4) than hospitals not participating in the COVID-19 response (HSMR, 124.3; 95% CI, 119.3 to 129.4).
Conclusions
This study suggests that the COVID-19 pandemic may have negatively impacted the quality of care in hospitals, especially general hospitals with relatively few beds. In light of the COVID-19 pandemic, it is necessary to prevent excessive workloads in hospitals and to properly employ and coordinate the workforce.

A 58-year-old male patient with severe claudication due to thrombosis of the left ilio-femoro-popliteal artery aneurysm. He also had a venous stasis ulcer with a history of multiple embolotherapy of arteriovenous malformation. Duplex sonography revealed reflux and varicose veins of the left great saphenous vein (GSV). A sequential bypass surgery was performed that consisted of excision of the left external iliac and common femoral artery aneurysm, external iliac to deep femoral interposition with an expanded polytetrafluoroethylene graft, and femoro-posterior tibial artery bypass with the reversed left GSV. Symptoms of claudication were alleviated and the chronic ulcer was healed in time. To our knowledge, this is the first report of successful bypass in a patient with arterial aneurysm, arteriovenous malformation, and venous insufficiency that can be diagnosed as an atypical case of Parkes Weber syndrome. Long-term follow-up is needed to define the fate of aneurysms and varicose vein graft.

PURPOSE: Neoadjuvant chemotherapy (NCT) is a treatment modality that increases the breast-conserving rate in breast cancer. This prospective study was performed to evaluate the actual breast-conserving rate using NCT in a clinical setting in a single institution. METHODS: Between 2014 and 2015, 265 patients who were scheduled to receive NCT and surgery were enrolled in this study. Patients were classified into three groups based on the immunohistochemical results of estrogen receptor (ER)/progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2): ER or PR positive (luminal), ER/PR negative and HER2 positive (HER2+), and triple-negative breast cancer (TNBC). Before starting and immediately after completing NCT, a surgeon decided if breast-conserving surgery (BCS) or total mastectomy (TM) should be performed. We analyzed the rate of type of surgery performed. RESULTS: Before administering NCT, 107 patients (40.4%) and 158 patients (59.6%) were candidates for BCS and TM, respectively. Of the 158 patients, 61 were eligible for BCS after chemotherapy, with a conversion rate of 38.6%. NCT increased the BCS eligible rate from 40.4% to 62.6%. Of the 61 patients, 53 chose to undergo BCS, and BCS was successful in 46 (86.8%). Of the 107 BCS candidates at baseline, 100 patents finally underwent BCS (93.5%). According to the subtype, the conversion rates were 35.4%, 50.0%, and 40.5% for luminal, HER2+, and TNBC groups, respectively. CONCLUSION: NCT increased the eligibility for BCS from 40.4% to 62.6% in a clinical setting. This benefit is similar to that observed in other clinical trials.

Objective:
To evaluate the efficacy and safety of 8 weeks of resistance circuit training in people with paraplegia due to spinal cord injury.
Methods:
Participants were randomized into experimental and control groups. Although the intensity and sequence of movements of the exercise programs were identical in both groups, the resting time between sets was limited to 1 minute in the experimental group. In the control group, the participants were allowed to rest until they were comfortable. Both groups received 8 weeks of training twice per week. Before and after the program, muscle mass, body fat percentage, fat mass, blood pressure, heart rate, muscle strength and muscular endurance were evaluated, and 6-minute propulsion test was conducted. Additionally, the safety of the program was assessed.
Results:
Twenty-two individuals with paraplegia were enrolled (11 in each group). After the training program, the experimental group showed a significant decrease in the resting blood pressure and improvement in the upper extremity muscle mass, strength, and endurance (p<0.05). Each variable showed significant inter-group differences (p<0.05). Furthermore, none of the participants showed autonomic adverse events, musculoskeletal side effects, or discomfort.
Conclusion
The results show that resistance circuit training programs with short resting intervals are superior to the usual resistance exercise programs in improving the blood pressure and physical strength and are safe for people with upper thoracic level injuries at T6 or higher.
