[Treatment of hematologic disorders in children by splenic artery ligation (author's transl)]
Insights
Splenic artery ligation in children offers an alternative to splenectomy for hematologic disorders, preserving spleen function and reducing sepsis risk. Most patients tolerated the procedure well, indicating its potential as a safer option, especially for young children.
Area of Science:
- Pediatric Surgery
- Hematology
- Interventional Radiology
Background:
- Splenectomy carries a significant risk of overwhelming postsplenectomy infection (OPSI).
- Reducing splenic function while preserving the spleen is a desirable alternative to splenectomy.
- Hematologic disorders like thalassemia, hereditary spherocytosis, and secondary hypersplenism often necessitate spleen-related interventions.
Purpose of the Study:
- To evaluate the efficacy and safety of splenic artery ligation (desarterization) in children with hematologic disorders.
- To determine if desarterization preserves splenic function and its protective role against infection.
- To assess splenic artery ligation as a potential alternative to splenectomy, particularly in pediatric patients.
Main Methods:
- 11 children with hematologic disorders underwent splenic artery ligation.
- Patient conditions included thalassemia, hereditary spherocytosis, and secondary hypersplenism.
- Follow-up assessments evaluated treatment outcomes, tolerance, and splenic function post-procedure.
Main Results:
- One patient died due to overlooked splenic necrosis.
- The remaining 10 patients showed positive outcomes with an average follow-up of 19 months.
- Hereditary spherocytosis and secondary hypersplenism were satisfactorily treated, suggesting preserved splenic function.
Conclusions:
- Splenic artery ligation is a viable treatment option for certain pediatric hematologic disorders, offering an alternative to splenectomy.
- The procedure appears well-tolerated and may preserve the spleen's immune function, mitigating OPSI risk.
- Splenic artery ligation is particularly recommended for children under 5 years old due to the high risks associated with splenectomy in this age group.
Abstract:
Because of the risk of overwhelming sepsis following splenectomy, and since it is possible to reduce the splenic function while preserving the spleen, the treatment of various hematologic disorders by splenic artery ligation has been attempted in 11 children, among whom 3 under 5 years of age. 3 patients had thalassemia, 4 had hereditary spherocytosis and 4 others suffered from secondary hypersplenism. One patient died of overlooked splenic necrosis. The other patients are well, with an average follow-up of 19 mo. The aim of this study is to find out whether the desarterization produces the expected results and is well tolerated and whether the desarterialized spleen still preserves its ability to protect the host against infection. The satisfactory treatment of hereditary spherocytosis and secondary hypersplenism would indicate that splenic artery ligation offers an alternative to splenectomy, especially in children under 5 year old.
