Malignancy and hematologic autoimmune disorders ,
*
Idiopathic thrombocytopenic purpura (ITP)
o autoimmune hemolytic anemia
What is Hereditary spherocytosis (HS) is the most common type of hemolytic anemia for which splenectomy is indicated
Hereditary spherocytosis (HS) is the most common
What is most common glycolytic defect causing congenital non spherocytic hemolytic anemia
Pyruvate kinase (PK) deficiency
The most common red blood cell enzyme deficiency overall is …….. deficiency .
G6PD
Splenectomy is indicated for patients with excessive
transfusion requirements ,………
(>200 mL/kg per year)
The low platelet count stems from premature removal of platelets opsonized by ………………autoantibodies produced
in the spleen.
antiplatelet immunoglobulin G
Petechial hemorrhages in the lower extremities are the most common presenting sign of
Thrombotic Thrombocytopenic Purpura
What happens at Thrombotic Thrombocytopenic Purpura
Abnormal platelet clumping occurs in arterioles and
capillaries, reducing the lumen of these vessels and
predisposing the patient to microvascular thrombotic
episodes.
HCL is characterized by ……
splenomegaly, pancytopenia, and large numbers of abnormal lymphocytes in the bone marrow.
WhgaT İS THE Proliferation of any one of the three predominant lymph cell types Non Hodgkin’s Lymphoma,?
natural killer cells, T cells, or B cells
WHİCH İNFECTİONS CAN CAUSE SPLENO MEAGALY
Epstein Barr virus or cytomegalovirus infection
spontaneous splenic rupture in both
adults and children.
What is the name of this disease thatrr cause parasitic cyst of spleen
Echinococcus species.
what is Felty syndrome (FS
is a rare extra-articular manifestation of seropositive rheumatoid arthritis (RA) characterized by RA, neutropenia, and splenomegaly. Severe or recurrent infection is of particular concern due to neutropenia, especially in the skin and respiratory system.
What is Wandering Spleen
The spleen “floats” inside the abdominal cavity
Due to an anomaly duringembryogenesis
ü,
Presentation: acute abdomen
Not normally attached toadjacent viscera in the splenicfossa.
This may lead to splenictorsion and infarction.*Splenopexy or splenectomymay be required
