Acquired asplenia occurs for several reasons: . Following splenectomy due to splenic rupture from trauma or because of tumor; After splenectomy with the goal of interfering with splenic function, as a treatment for diseases (e.g. idiopathic thrombocytopenic purpura, thalassemia, spherocytosis), in which the spleen's usual activity exacerbates the disease
Where clinically appropriate, attempts are now often made to perform either surgical subtotal (partial) splenectomy, [18] or partial splenic embolization. [19] In particular, whilst vaccination and antibiotics provide good protection against the risks of asplenia, this is not always available in poorer countries. [20]
An overwhelming post-splenectomy infection (OPSI) is a rare but rapidly fatal infection occurring in individuals following removal (or permanent dysfunction) of the spleen. The infections are typically characterized by either meningitis or sepsis , and are caused by encapsulated organisms including Streptococcus pneumoniae . [ 3 ]
ATC code J07 Vaccines is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. [1] [2] [3] Subgroup J07 is part of the anatomical group J Antiinfectives for systemic use. [4]
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
Lack of a spleen, called asplenia, can occur by autosplenectomy or the surgical counterpart, splenectomy. Asplenia can increase susceptibility to infection. [3] Autosplenectomy can occur in cases of sickle-cell disease where the misshapen cells block blood flow to the spleen, causing scarring and eventual atrophy of the organ. [2]
Embolization, blocking off of the hemorrhaging vessels, is a newer and less invasive treatment. [3] When surgery is needed, the spleen can be surgically repaired in a few cases, but splenectomy is still the primary surgical treatment, and has the highest success rate of all treatments.
Splenic artery embolization is a minimally invasive procedure and, where successful, avoids splenectomy. If an individual's spleen is enlarged, as is frequent in mononucleosis , most physicians will advise against activities (such as contact sports ) where injury to the abdomen could be catastrophic.
