### Description Module

**Brief Summary:** Aim of our study is to find frequency and identify risk factors for venous thromboembolism development in patients who underwent surgery for colorectal cancer. There were 137 patients enrolled in our retrospective observational cohort study. Included patients were operated for incisional hernia in Saveljev University Surgery Clinic from January 2016 to December 2017. Compression duplex ultrasound of lower legs veins was performed in 2-14 days after surgery for all participants. The primary endpoint was the occurrence of the venous thromboembolism event, including pulmonary embolism.

### Conditions Module

**Conditions:**

- Colorectal Cancer

- Venous Thromboembolism

**Keywords:**

- colorectal cancer surgery

- thromboprophylaxis

### Outcomes Module

#### Primary Outcomes

**Description:** Screening ultrasound in the postoperative period was aimed at looking for signs of deep vein thrombosis. The imaged vessels included the common femoral, great saphenous, superficial femoral, deep femoral, popliteal, posterior tibial, and peroneal veins of both lower extremities. The presence of a thrombotic process in the vein was evidenced by the rigidity of its walls during compression by the sensor, the presence of hyperechoic inclusions, and the impossibility of visualizing blood flow during color mapping.

**Measure:** Venous Thromboembolism

**Time Frame:** was performed with median 4 days (min 2 day, max 14 days, interquartile range 2-5 days) after surgery
