Postpartum thrombus explained

The term "thrombus" mentioned after childbirth most often refers to a puerperal hematoma, a pocket of blood that can form in the vulvar or vaginal region. According to Dr. Olivier Marpeau, also known as @mon.gyneco, this condition can occur after a long or instrumental delivery, as well as after a seemingly simpler delivery.

Symptoms to watch for

The signs to watch for include very intense pain or increasing pain, especially with discomfort, swelling, or difficulty urinating. These symptoms warrant prompt medical attention.

Thrombus vs. deep vein thrombosis

In obstetrical language, the term "thrombus" has sometimes been used to refer to a hematoma after a vaginal delivery. However, it should not be confused with deep vein thrombosis, which is a clot formed in a blood vessel. Here, the concern is a collection of blood in the tissues, which can be vulvar, vaginal, vulvovaginal, or deeper.

How a thrombus forms

Dr. Olivier Marpeau explains that a blood vessel, artery or vein, can tear deeply, without the bleeding necessarily being visible externally. The blood then accumulates locally. This complication remains rare, but it can be serious, as the bleeding can be internal. This is why postpartum monitoring is not limited to visible bleeding: the medical team also monitors blood pressure, pulse, genital pain, and the resumption of spontaneous urination.
