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
Prognosis. Almost invariably fatal without treatment [2] 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 ...
The spleen is an organ within the lymphatic system and its primary function is to filter blood. However, the spleen also plays a key role in immune responses as it detects pathogens within the blood and secretes phagocytes to fight potential infection. Without these immune functions, individuals with isolated congenital asplenia are extremely ...
A splenectomy is the surgical procedure that partially or completely removes the spleen. The spleen is an important organ in regard to immunological function due to its ability to efficiently destroy encapsulated bacteria. Therefore, removal of the spleen runs the risk of overwhelming post-splenectomy infection, a medical emergency and rapidly ...
The spleen, in healthy adult humans, is approximately 7 to 14 centimetres (3 to in) in length. An easy way to remember the anatomy of the spleen is the 1×3×5×7×9×10×11 rule. The spleen is 1 by 3 by 5 inches (3 by 8 by 13 cm), weighs approximately 7 oz (200 g), and lies between the 9th and 11th ribs on the left-hand side and along the axis ...
Wandering spleen is most commonly diagnosed in young children [3] as well as women between the ages of 20 and 40. [6] Even so, the disease is very rare and fewer than 500 occurrences of the disease have been reported as of 2005, [3] of which around 148 (including both children and adult cases) were documented to have been from between 1960 and ...
An autosplenectomy (from 'auto-' self, '-splen-' spleen, ' -ectomy ' removal) is a negative outcome of disease and occurs when a disease damages the spleen to such an extent that it becomes shrunken and non-functional. [1] The spleen is an important immunological organ that acts as a filter for red blood cells, triggers phagocytosis of invaders ...
Splenic sequestration crisis is a life-threatening illness common in pediatric patients with homozygous sickle cell disease and beta thalassemia. Up to 30% of these children may develop splenic sequestration crisis with a mortality rate of up to 15%. This crisis occurs when splenic vaso-occlusion causes a large percentage of total blood volume ...
