Background and Objectives: Feasibility of coronary angiography (CAG) and percutaneous coronary intervention (PCI) via left snuffbox approach is still concerned. We aimed to investigate efficacy and safety of the left snuffbox approach for CAG and PCI. Methods: Left snuffbox approach was tried in 150 patients who planned to perform CAG or PCI for suspected myocardial ischemia between 1 November 2017 and 31 March 2018. Results: Success rate of radial artery (RA) cannulation via snuffbox approach was 88.0% (n=132). Among 132 individuals, 58 (43.9%) acute coronary syndrome (ACS) patients were included. The diameter of snuffbox RA was significantly smaller than conventional RA (2.57 mm vs. 2.72 mm, p<0.001) from quantitative computed angiography of 101 patients. However, CAG via snuffbox approach by 6 French sheath was successfully performed in all 132 patients. In addition, there was significant correlation between the snuffbox and conventional RA diameter (r=0.856, p<0.001). In 42 PCI cases, including 25 patients with acute myocardial infarction (AMI), the success rate of PCI via snuffbox approach was 97.6% (n=41). Intravascular imaging-guided PCI was performed in 8 (19.5%) patients and multi-vessel PCI in 4 (9.8%) cases. Regarding vascular complication, forearm swelling with bruising, not requiring surgery or transfusion, occurred in 2 (4.9%) PCI cases. Conclusions: Left snuffbox approach is suitable for CAG and PCI compared with the conventional radial approach.

Background: Although a residual intimal tear may contribute to the dilatation of the descending aorta following surgical repair of acute type I aortic dissection (AD), its causal relationship has not been elucidated by clinical data due to the limited resolution of imaging modalities. Methods: This study enrolled 41 patients (age, $55.2{\pm}11.9$ years) who were evaluated with dual-source computed tomography (CT) imaging of the whole aorta in the setting of the surgical repair of acute type I AD. Logistic regression models were used to determine the predictors of a composite of the aortic aneurysm formation (diameter >55 mm) and rapid aortic expansion (>5 mm/yr). Results: On initial CT, a distal re-entry tear was identified in 9 patients. Two patients failed to achieve proximal tear exclusion by the surgery. Serial follow-up CT evaluations (median, 24.6 months; range, 6.0 to 67.2 months) revealed that 14 patients showed rapid expansion of the descending aorta or aortic aneurysm formation. A multivariate analysis revealed that the residual intimal tear (odds ratio [OR], 4.31; 95% confidence interval [CI], 1.02 to 19.31) and the patent false lumen in the early postoperative setting (OR, 4.64; 95% CI, 0.99 to 43.61) were predictive of the composite endpoint. Conclusion: The presence of a residual intimal tear following surgery for acute type I AD adversely influenced the expansion of the descending aorta.

We report a case of cavernous hemangioma of the anterior mediastinum that was incidentally detected by chest radiography taken at a routine health check-up. A mass lesion was seen in the anterior mediastinum on computed tomography and magnetic resonance imaging. Direct surgical removal was performed for diagnosis and treatment through right thoracotomy. Histopathology confirmed the mass as a cavernous haemangioma. Post-operative course was uneventful.

The postoperative respiratory complications such as pneumonia and ARDS, are poor prognostic factors after esophagectomy in patients with esophageal cancer. To avoid these complications, there have been attempts to use minimally invasive approach. Recently introduced daVinciTM S surgical system is used in esophagectomy because of its advantages of minimal invasiveness, clear 3-dimensional imaging and precise handling of robotic arms. We report a 83-year-old esophageal cancer patient who underwent daVinciTMS robot-assisted esophagectomy, laparoscopic stomach mobilization followed by cervical esophagogastrostomy.

Epiphrenic diverticula are known to cause a series of complications. We report the case of a 54-year-old woman who was diagnosed with an epiphrenic diverticulum at a regular checkup in November 2006. Ten years later, she presented with massive hematemesis. Imaging studies revealed an epiphrenic diverticulum measuring 7.8 cm in diameter and a large amount of bleeding inside the diverticulum. Computed tomography showed fistula formation between the diverticulum and the left lower lobe of the lung, leading to the development of a pulmonary abscess. Diverticulectomy and $180^{\circ}$ posterior partial fundoplication were performed transabdominally. The pulmonary abscess was treated with antibiotics alone. She was discharged 16 days after the operation without any complications over 7 months of follow-up.
