Background Brachiocephalic vein aneurysm is a rare vascular malformation, which is often reported in case reports. At present it has attracted much attention due to the serious complications, such as vein aneurysm rupture, pulmonary embolism, venous thrombosis, etc. We report a case of left brachiocephalic vein aneurysm with compression symptoms. Case presentation a 52-year-old male who was admitted to our hospital with irritating cough for more than 1 month. Chest contrast-enhanced CT showed a localized expansion of 5.2 cm in diameter of the left brachiocephalic vein in the anterior mediastinum. The patient received venous angioplasty with brachiocephalic vein aneurysm resection, and the postoperative recovery was well. Conclusion Surgical operation is an effecive treatment method for brachiocephalic vein aneurysm, but it is still necessary to choose the appropriate way according to the type, size, location, lesion scope and complications of the vein aneurysm.

Background The relationship between body mass index (BMI) and postoperative mortality in patients who undergo coronary artery bypass graft (CABG) surgery plus valve replacement is uncertain. We aimed to investigate the association between body mass index (BMI) and postoperative mortality among patients who simultaneously underwent both CABG surgery plus valve replacement. Methods We retrospectively analyzed 1976 patients who underwent CABG surgery at our hospital between January 2017 and April 2021, including 202 patients who underwent valve replacement surgery during the same period. We analyzed the relationship between BMI and postoperative mortality. The relationship between BMI and postoperative mortality was assessed using smooth curve fitting and a Multiple logistic regression model. Results The results of smoothing curve fitting showed that BMI and postoperative mortality had a non-linear relationship, and the resulting curve exhibited a two-stage change and a breakpoint. Postoperative mortality is higher in patients that have a body mass index above 25 kg/m2 compared to patients having a body mass index between 18 and 25 kg/m2. Conclusions Our study found a non-linear relationship between BMI and postoperative mortality in patients undergoing CABG plus valve replacement after adjusting for potential confounders. The causal relationship between BMI and postoperative mortality still requires further investigations.

Background: Brachiocephalic vein tumor is a rare vascular malformation, which is often reported in case reports. At present it has attracted much attention due to the serious complications, such as vein tumor rupture, pulmonary embolism, venous thrombosis, etc. We report a case of left brachiocephalic vein tumor with compression symptoms.Case presentation: a 52-year-old male who was admitted to our hospital with irritating cough for more than one month. Chest contrast-enhanced CT showed a localized expansion of 5.2cm in diameter of the left brachiocephalic vein in the anterior mediastinum. The patient received venous angioplasty with brachiocephalic vein tumor resection, and the postoperative recovery was well.Conclusion: Surgical operation is an effecive treatment method for brachiocephalic vein tumor, but it is still necessary to choose the appropriate way according to the type, size, location, lesion scope and complications of the vein tumor.
