Summary
Diagnoses of ruptured abdominal aortic aneurysm (AAA) are frequently missed by internists, leading to delayed treatment and increased mortality. Early recognition of AAA symptoms is crucial for improving patient survival rates.
Area of Science:
- Vascular surgery
- Internal medicine
- Diagnostic accuracy
Background:
- Ruptured abdominal aortic aneurysm (AAA) is a life-threatening condition.
- Early diagnosis by internists is critical for patient survival.
- Missed diagnoses of ruptured AAA contribute to significant morbidity and mortality.
Observation:
- Most patients with ruptured AAA presenting to internists exhibited abdominal pain, tenderness, back/flank pain, and leukocytosis.
- Anemia and profound hypotension were uncommon presenting signs.
- A significant proportion of ruptured AAA cases (61%) were initially misdiagnosed by internists.
Findings:
- Common misdiagnoses included urinary tract obstruction/infection, spinal disease, and diverticulitis.
- Delayed diagnosis, often until shock developed, adversely affected survival outcomes.
- Mortality was higher in patients who experienced preoperative shock and in those who did not undergo surgery.
Implications:
- Increased physician awareness of ruptured AAA clinical features is essential.
- Internists require enhanced education on the presentation and management of ruptured AAA.
- Timely diagnosis and intervention in ruptured AAA cases can improve patient survival.
