O88.23

Clinical Causes: Changes in blood clotting factors during pregnancy, which make blood more prone to clotting Reduced mobility after childbirth, increasing risk of blood stasis in veins Injury to blood vessels during delivery or after procedures such as cesarean sections Obesity, which can impair blood circulation Previous history of blood clots or thrombophilia (a genetic tendency to develop blood clots) Prolonged bed rest or immobility during or after pregnancy Use of hormone-based contraceptives or hormone therapy postpartum Advanced maternal age Cesarean birth (C-section), which is associated with higher risk compared to vaginal delivery

Key Symptoms: Sudden shortness of breath Chest pain that may worsen with deep breathing or coughing Rapid heartbeat or palpitations Cough, which may be bloody Lightheadedness or fainting Swelling, redness, or pain in the legs (if originating from DVT, a common precursor) Feeling of anxiety or extreme restlessness

Diagnosis Path: Medical history review and physical examination D-dimer blood tests to detect abnormal clotting activity Ultrasound or Doppler studies of the legs to identify deep vein thrombosis (DVT) Chest X-ray to rule out other lung conditions Ventilation-perfusion (V/Q) scan or computed tomography pulmonary angiography (CTPA) to visualize pulmonary emboli Electrocardiogram (ECG) to monitor heart function Blood tests to assess blood clotting factors

Treatment Protocols: Anticoagulant medications such as heparin or low-molecular-weight heparin to thin the blood and prevent clot growth Transition to oral anticoagulants like warfarin or direct oral anticoagulants (DOACs) for ongoing treatment Supportive care including oxygen therapy if breathing is compromised In severe cases, thrombolytic therapy to actively dissolve clots Monitoring for bleeding complications due to anticoagulant use Encouraging early mobilization and movement after delivery to reduce clot risk Addressing underlying risk factors, such as weight management or treating thrombophilia
