Pregnancy and fertility questions are full of dates, ranges, and probabilities—not certainties. VTE Risk Score Calculator in Pregnancy narrows the question to the exact inputs shown and gives a practical estimate without pretending biology runs on a perfect calendar.

What this calculator does

VTE Risk Score Calculator in Pregnancy uses Patient’s current situation, Height, Weight, Previous VTE (except single major-surgery-related event), Previous VTE provoked by major surgery, Known high-risk thrombophilia, Medical comorbidity, and the remaining fields shown to calculate pregnancy VTE risk score. It is built around the exact fields displayed in this plugin rather than a generic version of the topic. Pregnancy and fertility dates, hormone trends, and risk scores are estimates built around biologic averages. Cycle variation, ultrasound findings, assisted-reproduction details, and the individual pregnancy can matter more than a single calculated number.

How to use it

Complete the requested fields, including Patient’s current situation, Height, Weight, Previous VTE (except single major-surgery-related event), Previous VTE provoked by major surgery, and Known high-risk thrombophilia, then finish the remaining items shown in the calculator. Confirm that each yes/no, category, date, or score option is applied exactly as labeled. For paired dates or serial measurements, keep them within the same menstrual cycle, pregnancy, or treatment episode as the calculator requires.

How the calculation works

The calculator sums the RCOG-style point values selected for antenatal/postpartum VTE risk factors. BMI is calculated from height and weight and adds one point at BMI 30–39.9 or two at BMI 40 or higher; the remaining risk factors contribute their stored point values. The situation selector is reported to distinguish antenatal from postpartum context.

Example

For example, with height 1.65 m, weight 68 kg, and no additional risk factors selected, BMI is about 25 and contributes no BMI points, so the risk-score total remains 0. Adding any listed risk factor increases the total by the point value shown for that item.

How to interpret the result

Treat the output as the calculated result based on the assumptions encoded in this calculator. It can help with planning or understanding a measurement, but pregnancy and reproductive biology vary enough that the calculated date, ratio, or probability should be seen as a range or estimate rather than a guarantee.

Limitations and notes

Pregnancy-associated VTE prophylaxis decisions depend on timing, bleeding risk, neuraxial-anesthesia plans, contraindications, prior VTE details, thrombophilia type, and local/national guidance. A point score helps structure assessment but does not prescribe anticoagulant type, dose, or duration by itself.
