Diagnostik und Therapie der Lungenarterienembolie

In recent years the diagnostics of pulmonary artery embolisms (PE) has gained significance, with confirmation occurring in only about 15–25 % of suspected cases. Despite technological advances, radiological methods remain problematic due to radiation and contrast medium exposure. Clinical scores play a crucial role in the risk assessment of PE. High-risk situations call for specific measures, while negative D‑dimers can help avoid overdiagnosis. Computed tomographic pulmonary angiography (CTPA) remains the gold standard with high sensitivity and specificity. Treatment requires an interdisciplinary team (pulmonary embolism response team, PERT). Anticoagulation is an option for stable patients, while in unstable or unsuccessful courses, thrombolysis or interventional procedures can be considered. Side effects, especially the risk of bleeding, need to be considered for both forms of treatment.
