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 to become trapped within the spleen. Clinical signs include severe, rapid drop in hemoglobin leading to hypovolemic shock and death.
Increased deoxygenation causes sickling of red blood cells, which adhere to the spleen wall and splenic macrophages causing ischemia. [2] This ischemia can result in splenic sequestration, where large amounts of blood pool in the spleen but do not flow within vasculature. [11]
One common definition of thrombocytopenia requiring emergency treatment is a platelet count below 50,000/μL. [5] Thrombocytopenia can be contrasted with the conditions associated with an abnormally high level of platelets in the blood – thrombocythemia (when the cause is unknown), and thrombocytosis (when the cause is known). [6] [7]
The spleen is especially prone to damage in SCD due to its role as a blood filter. A splenic sequestration crisis, also known as a spleen crisis, is a medical emergency that occurs when sickled red blood cells block the spleen's filter mechanism, causing the spleen to swell and fill with blood. The accumulation of red blood cells in the spleen ...
Thrombotic thrombocytopenic purpura (TTP) initially presents with a range of symptoms that may include severe thrombocytopenia (platelet count usually < 30,000/mm³), microangiopathic hemolytic anemia (evidenced by schistocytes in the blood smear), and various clinical signs such as petechiae, purpura, neurologic symptoms, myocardial ischemia ...
The basic pathology is some kind of obstructive pathology in the portal, hepatic or splenic vein that causes obstruction of venous blood flow from the spleen towards the heart. The cause of such obstruction may be abnormalities present at birth (congenital) of certain veins, blood clots, or various underlying disorders causing inflammation and ...
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
A hematoma caused by a dislodged needle during a plateletpheresis donation. Adverse conditions that can happen during a plateletpheresis donation are hypocalcemia, hematoma formation, and vasovagal reactions. The risk of these conditions is normally reduced by pre-donation education of the donors and change of apheresis machine configuration. [6]
