Postpartum venous thrombosis is a rare but potentially life-threatening condition demanding swift medical attention, experts warn. While the body undergoes natural changes after childbirth to prevent postpartum hemorrhage, these shifts also elevate the risk of blood clots forming in veins-a condition known as venous thromboembolic disease. Specialists at Ruber Internacional Hospital in Madrid are emphasizing the importance of awareness among both healthcare providers and new mothers regarding the risk factors, symptoms, and treatment options available.

MADRID 19 Ene. (EUROPA PRESS) –
Postpartum venous thrombosis, while uncommon, is a serious medical emergency that requires prompt diagnosis and treatment to save lives, according to Pablo Gallo González, head of the Angiology and Vascular Surgery Unit at Ruber Internacional Hospital.
The period after childbirth, known as the puerperium, presents a naturally heightened risk of blood clot formation, necessitating careful clinical monitoring. This physiological state is a protective mechanism against postpartum hemorrhage, but it can also increase the likelihood of developing venous thromboembolic disease, encompassing deep vein thrombosis, pulmonary embolism, and thrombophlebitis. Understanding these risks is crucial for both healthcare providers and new mothers.
This increased risk is attributed to a combination of factors known as Virchow’s Triad: venous stasis caused by the uterus compressing pelvic veins; damage to the inner lining of veins, potentially from childbirth or procedures like cesarean sections; and hypercoagulability, or an increased tendency for blood to clot, due to rising levels of coagulation factors like fibrinogen.
Additional risk factors include inherited or acquired thrombophilias, a personal or family history of thrombosis, pelvic varicose veins, obesity, immobility, smoking, maternal age over 35, and postpartum complications like sepsis.
Recognizing the warning signs of postpartum thrombosis can be challenging because symptoms can mimic common postpartum discomforts, explained Santiago Zubicoa Ezpeleta, head of the Vascular Radiology Unit at Ruber Internacional Hospital. “It’s fundamental to recognize the alarm signals.”
Symptoms to watch for include pain in the leg, pelvis, or abdomen; swelling in a limb, particularly the left leg; persistent fever without a clear cause; shortness of breath or chest pain, potentially indicating a pulmonary embolism; and a painful, inflamed cord along a vein.
DIAGNÓSTICO Y TRATAMIENTO
Diagnosis typically begins with a clinical evaluation and further testing. “The venous Doppler ultrasound is the initial tool due to its speed and reliability,” Zubicoa noted. If a pulmonary embolism is suspected, a pulmonary angio-CT scan is performed, and for complex pelvic thrombosis, an angio-MRI may be used.
Treatment varies depending on the severity of the condition but generally centers around anticoagulation, along with relative rest and compression stockings. Severe cases or those unresponsive to initial treatment may require more advanced interventions such as thrombectomy, pharmacological or mechanical thrombolysis, or, in rare instances, inferior vena cava filters to prevent pulmonary embolism.
Gallo and Zubicoa both emphasized the importance of prevention, particularly for women with existing risk factors. Prophylactic low molecular weight heparin (LMWH) for four to six weeks, early mobilization, compression stockings, and avoiding prolonged sitting can significantly reduce the risk.
