[Suppurating splenic infarction originating from endocarditis]
Insights
Early splenectomy is crucial for bacterial endocarditis patients with splenic infarction and abscess. Prompt diagnosis via imaging and surgical intervention can prevent life-threatening complications.
Area of Science:
- Infectious Diseases
- Surgical Pathology
- Diagnostic Imaging
Background:
- Bacterial endocarditis can lead to splenic complications, including infarction and abscess formation.
- Splenic infarction and abscesses in endocarditis patients present diagnostic challenges.
- Splenic rupture is a known, high-mortality complication of splenic infarction.
Observation:
- Three cases of splenic infarction with abscess formation during bacterial endocarditis are presented.
- Clinical abdominal signs were present in all cases; one had persistent positive hemocultures.
- Computed tomography (CAT) scanning was instrumental in diagnosing splenic lesions in these patients.
Findings:
- Ultrasonography and abdominal CAT scanning are highly sensitive for detecting splenic lesions.
- Early splenectomy is indicated for splenic infarction complicated by abscess, especially with clinical signs of infection.
- Splenectomy is recommended concurrently with valve replacement in such cases to prevent prosthesis infection.
Implications:
- Early diagnosis and surgical management of splenic complications in endocarditis are vital.
- Splenectomy can mitigate the high mortality associated with splenic rupture.
- This approach may improve outcomes for patients with complex endocarditis presentations.
Abstract:
Three cases of splenic infarction complicated by abscess formation during bacterial endocarditis are reported. In all three cases there were associated clinical abdominal signs and, in one case, there was persistently positive hemocultures. The diagnosis was made by CAT scanning. The three patients underwent splenectomy and one patient also underwent valve replacement the same day. The methods of early diagnosis of splenic complications during endocarditis and the indications of splenectomy are discussed. Ultrasonography and abdominal CAT scanning are the most sensitive diagnostic methods for splenic lesions. As splenic rupture is associated with a high mortality and this complication may occur at any time during infarction complicated by abscess formation, early splenectomy is justified when abdominal clinical signs are elicited associated with a persistent, infectious syndrome with or without positive blood cultures, under appropriate antibiotic therapy. Splenectomy should also be considered if valve replacement is carried out in the same circumstances to avoid infection of the prosthesis.
