Description
Pulmonary embolism is a blockage in one of the pulmonary arteries in the lungs usually caused by thrombus from a distant site. 75% of thrombi are generated in the deep venous system of the lower limbs and pelvis, probably initiated by platelet aggregation around venous valve sinuses. Join us on the upcoming webinar with Dr Viny Kantroo to learn more about the Risk factors of Pulmonary Thromboembolic Diseases and its importance for an assessment of clinical probability.
Summary Listen
- The presentation discusses various case scenarios of pulmonary thromboembolism (PTE) to highlight diagnostic and treatment approaches. It emphasizes the importance of recognizing risk factors, such as immobilization, recent surgery, and genetic predispositions.
- The speaker presents five cases, including a young trauma patient, a nurse with asthma and possible autoimmune issues, a post-operative patient, and patients with pre-existing conditions like COPD. Each case highlights the need to consider PTE even with atypical symptoms.
- The presentation explores clinical signs and symptoms like dyspnea, pleuritic chest pain, and hemoptysis, emphasizing that pulmonary embolism can present with non-specific complaints, so high clinical suspicion and detailed patient history are crucial.
- Diagnostic tools, including Well's score, revised Geneva score, D-dimer testing, and CT pulmonary angiography are discussed. CTPA is considered the gold standard, but clinical suspicion outweighs test results.
- The presenter explains the classification of pulmonary embolism into massive, submassive, and low-risk categories based on hemodynamic stability and right heart strain. This classification helps determine the appropriate treatment, whether thrombolysis or anticoagulation.
- The speaker details the management of PTE, including resuscitation, anticoagulation with heparin or enoxaparin, and thrombolysis. Direct oral anticoagulants are also mentioned as an option, with appropriate dosing emphasized.
- Referral to specialists like pulmonologists or cardiologists is recommended in complex cases. Specific instances are patients with CTPA evidence of right heart strain, those who are unable to perform CTA, patients with pre-existing conditions, or recent surgery.
