The incidence of venous thromboembolism in cardiovascular surgery is suggested to be low. However, the true incidence is unknown. This observational study aimed to evaluate deep vein thrombosis using ultrasonography in 70 patients who underwent cardiovascular surgery. The incidence of new deep vein thrombosis was 7.1%. Furthermore, no significant differences in postoperative outcomes, postoperative blood tests, or other major outcome measures were observed between patients who developed thrombosis and those who did not. Postoperative contrast-enhanced CT was performed, and the incidence of pulmonary artery thromboembolism was 0%.

We report a rare surgical case of multimodal subclavian aneurysm. A 71-year-old female referred to our hospital to treat bimodal saccular subclavian aneurysms accidentaly found on CT. Her vagus and recurrent laryngeal nerves were entangled in the aneurysm and displaced medially. A supraclavicular approach utilizing transection of the sternal head of sternocleidomastoid muscle provided an enough surgical field and the operation was performed uneventfully. The postoperative course was favorable. Multimodal subclavian aneurysm is rare, and we report it with reference to the literature.
