[Dissecting aneurysm of the aorta presenting as acute pericarditis (author's transl)]
Insights
Aortic dissecting aneurysms can mimic acute pericarditis. Early diagnosis using echocardiography and aortography is crucial for managing this rare condition, especially in patients with hypertension or coarctation of the aorta.
Area of Science:
- Cardiology
- Vascular Surgery
- Diagnostic Imaging
Background:
- Aortic dissecting aneurysms are life-threatening conditions.
- Leakage into the pericardial cavity can present atypically as acute pericarditis.
- Risk factors like hypertension and coarctation of the aorta are important diagnostic clues.
Observation:
- Two cases of aortic dissecting aneurysm with pericardial effusion are presented.
- Clinical presentation mimicked acute pericarditis.
- Echocardiography revealed aortic enlargement and wall thickening, suggesting aortic insufficiency.
Findings:
- Aortography confirmed the diagnosis of aortic dissecting aneurysm in both cases.
- One patient experienced a fatal outcome post-surgery.
- The other patient was successfully managed with hypotensive medication.
Implications:
- A high index of suspicion is necessary for diagnosing atypical presentations of aortic dissecting aneurysms.
- Prompt diagnosis via echocardiography and aortography is vital for effective management.
- Understanding risk factors aids in early identification and intervention.
Abstract:
Two cases of leakage of an aortic dissecting aneurysm into the pericardial cavity presenting as acute pericarditis are reported. In both cases the existence of risk factors (hypertension and coarctation of the aorta) suggested the correct diagnosis. Echocardiography showed enlargement of the ascending aorta and thickening of vascular wall in the two cases, furthermore it suggested the presence of aortic insufficiency in one case. The definite diagnosis was made by means of aortography. One patient died after surgery, while the other was successfully treated with hypotensive drugs. Dissecting aneurysm of the aorta may present atypical clinical manifestations; in these circumstances a great suspicion index is the basis for a correct diagnosis. The importance of an early diagnosis by means of aortography and echocardiography is emphasized.
