Objectives
Narrative objectives1
Deep vein thrombosis in the perioperative period is a serious complication, one of which is pulmonary embolism, which can lead to shock and sudden death. Despite standard prophylaxis, it still occurs, and its exact cause remains unknown. In this study, we will clarify the relationship with protein S ratio activity, which is considered one of the possible causes of venous thrombosis in the perioperative period.

Other related information
(1) Patients who have undergone surgery at Kyushu University Hospital or at a collaborating hospital and meet the eligibility criteria for research subjects will be informed in writing of their consent to participate in this study, after providing the individual with an explanation in accordance with the attached explanatory document.
(2) Patients whose consent has been obtained will be enrolled as research subjects, and the following information will be obtained from their medical records.
Information to be obtained
Age, gender, height, weight, current medical history, medical history, regular medications, surgical procedure (postoperative), blood test results (PT, APTT, blood count, FDP, D-dimer, TAT, PIC,), and leg vein echo
(3) In addition to the 15 ml of blood drawn during the usual medical examination, an additional 5 ml of blood will be drawn for research purposes.
Blood samples will be drawn twice, once at the time of VTE diagnosis and once at the time of discharge from the hospital.
(3) Samples, medical information, and personal information will be anonymized using a correspondence table.
(4) The collaborative research institute will send the specimens to an outside testing company for analysis of protein S specific activity, and the test results sent by the outside testing company and the medical information of the patients anonymized by the collaborative research institute will be sent to Kyushu University.
(5) Kyushu University will also send specimens to an external testing company and request analysis of protein S specific activity. Kyushu University will collect the medical information and test results sent from each collaborating institution.
