Summary
Low body mass index and elevated D-dimer levels predict deep vein thrombosis (DVT) risk in surgical patients. D-dimer screening can help reduce unnecessary preoperative tests, optimizing surgical care.
Area of Science:
- Medical Science
- Surgical Care
- Diagnostic Imaging
Background:
- Healthcare systems face challenges with surgeon shortages and reduced medical staff.
- Minimizing unnecessary diagnostic tests is crucial to alleviate staff burden in regional medical care.
Purpose of the Study:
- To identify predictors of deep vein thrombosis (DVT) in surgical patients.
- To evaluate the feasibility of using D-dimer levels for DVT screening preoperatively.
Main Methods:
- Retrospective analysis of 310 surgical cases with preoperative lower extremity ultrasonography.
- Comparison of 46 patients with DVT (thrombi) and 264 patients without DVT.
Main Results:
- Low body mass index (<18.5 kg/m²) and high D-dimer levels (>2 μg/mL) significantly increased DVT risk.
- Oral antiplatelet drugs and anticoagulants were associated with a lower risk of DVT.
- D-dimer levels showed an area under the curve of 0.779 for DVT prediction, with a threshold of 1.4 μg/mL achieving 100% sensitivity.
Conclusions:
- D-dimer levels show potential effectiveness in predicting DVT risk in surgical patients.
- Integrating D-dimer levels with patient background information may help reduce excessive preoperative testing.
- Optimizing diagnostic strategies can improve efficiency in surgical patient management.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
