Abstract
RATIONALE: Venous thromboembolism (VTE) is a dangerous condition that has a major global impact on morbidity and death. VTE risk factors include both pregnancy and fracture. PATIENT CONCERNS: The patient was hospitalized during pregnancy due to a right lower extremity fracture that was complicated by deep vein thrombosis (DVT) - a condition carrying a risk of fatal pulmonary embolism - and was found to have inferior vena cava (IVC) syndrome. DIAGNOSES: DVT of the right lower extremity, right femoral fracture, pregnancy, and IVC syndrome. INTERVENTIONS: The patient underwent several procedures, including IVC filter placement, fracture surgery, cesarean section, and thrombus aspiration, in addition to receiving anticoagulation therapy and other medications. OUTCOMES: After treatment, the patient's right lower extremity swelling subsided, with no symptoms such as chest tightness or chest pain. Both lower extremities were fully mobile, and the patient was discharged without complications. Her infant was healthy. LESSONS: Although no pregnancy-related VTE preventive guidelines have specified IVC compression as an evaluation item, we took into account the patient's right femoral fracture and IVC compression, which were linked to the rapid onset of DVT in this case. More research is necessary to determine whether IVC compression and pregnancy-related VTE are clearly correlated.
