Surgical procedure involving either partial or entire removal of the spleen.
Condition characterized by splenomegaly, some reduction in the number of circulating blood cells in the presence of a normal or hyperactive bone marrow, and the potential for reversal by splenectomy.
'Splenic diseases' refer to a range of medical conditions that affect the structure, function, or integrity of the spleen, leading to various symptoms and potential complications such as anemia, infection, or abdominal pain.
Enlargement of the spleen.
Tumors or cancer of the SPLEEN.
Thrombocytopenia occurring in the absence of toxic exposure or a disease associated with decreased platelets. It is mediated by immune mechanisms, in most cases IMMUNOGLOBULIN G autoantibodies which attach to platelets and subsequently undergo destruction by macrophages. The disease is seen in acute (affecting children) and chronic (adult) forms.
Vein formed by the union (at the hilus of the spleen) of several small veins from the stomach, pancreas, spleen and mesentery.
The largest branch of the celiac trunk with distribution to the spleen, pancreas, stomach and greater omentum.
A splenic rupture is a medical condition characterized by the traumatic tearing or disruption of the spleen, leading to potential internal bleeding and, if left untreated, potentially life-threatening complications.
A group of familial congenital hemolytic anemias characterized by numerous abnormally shaped erythrocytes which are generally spheroidal. The erythrocytes have increased osmotic fragility and are abnormally permeable to sodium ions.
An encapsulated lymphatic organ through which venous blood filters.
The number of PLATELETS per unit volume in a sample of venous BLOOD.
Any form of purpura in which the PLATELET COUNT is decreased. Many forms are thought to be caused by immunological mechanisms.
A procedure in which a laparoscope (LAPAROSCOPES) is inserted through a small incision near the navel to examine the abdominal and pelvic organs in the PERITONEAL CAVITY. If appropriate, biopsy or surgery can be performed during laparoscopy.
Abnormal increase of resistance to blood flow within the hepatic PORTAL SYSTEM, frequently seen in LIVER CIRRHOSIS and conditions with obstruction of the PORTAL VEIN.
ENDOSCOPES for examining the abdominal and pelvic organs in the peritoneal cavity.
The spontaneous transplantation of splenic tissue to unusual sites after open splenic trauma, e.g., after automobile accidents, gunshot or stab wounds. The splenic pulp implants appear as red-blue nodules on the peritoneum, omentum, and mesentery, morphologically similar to multifocal pelvic endometriosis. (Segen, Dictionary of Modern Medicine, 1992)
Disorders of the blood and blood forming tissues.
Extravasation of blood into the skin, resulting in a nonelevated, rounded or irregular, blue or purplish patch, larger than a petechia.
Surgical removal of the pancreas. (Dorland, 28th ed)
Insufficiency of arterial or venous blood supply to the spleen due to emboli, thrombi, vascular torsion, or pressure that produces a macroscopic area of necrosis. (From Stedman, 25th ed)
Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.
A subnormal level of BLOOD PLATELETS.
Acquired hemolytic anemia due to the presence of AUTOANTIBODIES which agglutinate or lyse the patient's own RED BLOOD CELLS.
Infection of the spleen with species of MYCOBACTERIUM.
An autosomal recessive disorder caused by a deficiency of acid beta-glucosidase (GLUCOSYLCERAMIDASE) leading to intralysosomal accumulation of glycosylceramide mainly in cells of the MONONUCLEAR PHAGOCYTE SYSTEM. The characteristic Gaucher cells, glycosphingolipid-filled HISTIOCYTES, displace normal cells in BONE MARROW and visceral organs causing skeletal deterioration, hepatosplenomegaly, and organ dysfunction. There are several subtypes based on the presence and severity of neurological involvement.
Anastomosis of splenic vein to renal vein to relieve portal hypertension.
A de novo myeloproliferation arising from an abnormal stem cell. It is characterized by the replacement of bone marrow by fibrous tissue, a process that is mediated by CYTOKINES arising from the abnormal clone.
Hemolytic anemia due to various intrinsic defects of the erythrocyte.
Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).
A congenital or acquired condition in which the SPLEEN is not in its normal anatomical position but moves about in the ABDOMEN. This is due to laxity or absence of suspensory ligaments which normally provide peritoneal attachments to keep the SPLEEN in a fixed position. Clinical symptoms include ABDOMINAL PAIN, splenic torsion and ISCHEMIA.
A rare complication of rheumatoid arthritis with autoimmune NEUTROPENIA; and SPLENOMEGALY.
Injuries caused by impact with a blunt object where there is no penetration of the skin.
A short thick vein formed by union of the superior mesenteric vein and the splenic vein.
A neoplastic disease of the lymphoreticular cells which is considered to be a rare type of chronic leukemia; it is characterized by an insidious onset, splenomegaly, anemia, granulocytopenia, thrombocytopenia, little or no lymphadenopathy, and the presence of "hairy" or "flagellated" cells in the blood and bone marrow.
