The study included women admitted to hospital for one or more days for reasons other than delivery or venous thromboembolism. [5] Pregnancy after the age of 35 augments the risk of VTE, as does multigravidity of more than four pregnancies. [2] Pregnancy in itself causes approximately a five-fold increased risk of deep venous thrombosis. [6]
Thrombosis prevention is also recommended during air travel. [7] Thrombosis prophylaxis is effective in preventing the formation of blood clots, their lodging in the veins, and their developing into thromboemboli that can travel through the circulatory system to cause blockage and subsequent tissue death in other organs.

VTE occurs in association with hospitalization or nursing home residence about 60% of the time, active cancer about 20% of the time, and a central venous catheter or transvenous pacemaker about 9% of the time. [3] During pregnancy and after childbirth, acute VTE occurs in about 1.2 of 1000 deliveries.
Venous thromboembolism occurs in 100–200 per 100,000 pregnant women every year. [23] Regarding family history, age has substantial effect modification. For people with two or more affected siblings, the highest incidence rate is found among those ≥70 years of age (390 per 100,000 in men and 370 per 100,000 in women), whereas the highest ...
IPK with inflatable trousers. Intermittent pneumatic compression is a therapeutic technique used in medical devices that include an air pump and inflatable auxiliary sleeves, gloves or boots in a system designed to improve venous circulation in the limbs of patients who have edema or the risk of deep vein thrombosis (DVT), pulmonary embolism (PE), or the combination of DVT and PE, venous ...
Deep vein thrombosis, a form of venous thromboembolism, has an incidence of 0.5 to 7 per 1,000 pregnancies, and is the second most common cause of maternal death in developed countries after bleeding. [30] Caused by: Pregnancy-induced hypercoagulability as a physiological response in preparation for the potential bleeding during childbirth. [30]
In 2021, the items of the Revised Geneva Score were re-evaluated on pregnant women. [4] Some items were removed, and the threshold values for the remaining items were modified to better discriminate patients even with the altered physiologic baseline of pregnancy (e.g. higher cut-off value for heart rate, lower cut-off value for age).
Pregnancy itself is a factor of hypercoagulability (pregnancy-induced hypercoagulability), as a physiologically adaptive mechanism to prevent post partum bleeding. [41] However, when combined with an additional underlying hypercoagulable states, the risk of thrombosis or embolism may become substantial.
