Some causes of a pelvic blood clot can include childbirth, pelvis fracture, bed confinement, pelvic surgery, ulcerative colitis and some types of cancer. In women, blood clots can develop up to 6 weeks after childbirth, as noted by the Center for Disease Control and Prevention. Postpartum blood clots, which are blood masses that can obstruct blood flow in blood vessels, can develop in the leg and pelvic regions.
If these blood clots break off and travel from these regions to the lungs, it can cause a blockage and lead to pulmonary embolism, as reported by Merck Manuals. This can cause a symptom like shortness of breath. For a pulmonary embolism, the treatment is an anticoagulant drug.
Blood clots can develop in other areas of the body such as the arms, brain and heart. Symptoms of a blood clot are dependent on its location. Pelvic blood clots can present symptoms such as blood in the stool, nausea and pain in the abdomen.
To evaluate or diagnose a pelvic blood clot, some tests used are a computed tomography scan of the chest or pelvic regions and a chest X-ray in cases where the clot has traveled to the lungs, as explained by the Radiological Society of North America. Blood clots that develop in the deep veins of the pelvic or leg areas are referred to as deep vein thrombosis. One type of treatment for this condition can be medication.
