Cerebral venous thrombosis (CVT) is an uncommon cause of stroke. Paroxysmal nocturnal hemoglobinuria (PNH) is a rare type of hemolytic anemia, frequently associated with thrombophilia. PNH may rarely present with CVT. Approximately, one-third of the patients with CVT develop cerebral hemorrhage.
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare disorder characterized by intravascular hemolysis, hemoglobinuria, and thrombosis. Thrombotic attacks are life threatening and are responsible for nearly 50% of PNH-related deaths. Compared with thrombotic events, bleeding related to
A 67-year-old lady was admitted with a myocardial infarction. Coronarography revealed thrombotic material within coronary arteries. The underlying disease was paroxysmal nocturnal hemoglobinuria (PNH), a stem cell defect characterized by episodes of complement-induced hemolysis and thromboembolic
OBJECTIVE
To report a patient with paroxysmal nocturnal hemoglobinuria who complained of transient obscurations of vision and exhibited bilateral papilledema with retinal hemorrhages.
METHODS
Case report. Computed tomography did not demonstrate any abnormality but magnetic resonance imaging
An 80-year-old female presented with melena and anemia due to bleeding from a benign gastric ulcer. Her blood group was O, D+. The serum contained anti-B and a weak anti-A (titer 2 at 18 degrees C). She was inadvertently transfused with approximately 3.5 units of group A red blood cells with no
Two hundred and three cases of PNH diagnosed (according to the National Unified Diagnosed Criteria, 1987) and treated from 1949 to 1992 in Peking Union Medical Hospital were analyzed retrospectively in an attempt to investigate the factors leading to delayed diagnosis. The presenting manifestation
An eight year old boy presented with severe anemia and bleeding spots. Complete blood count showed pancytopenia. There was mild reticulocytosis. Bone marrow was hypocellular with normoblastic erythroid hyperplasia. Ham's test (acidified serum test) was positive which confirmed the diagnosis of
We tested an in vitro system simulating bleeding time reported by Kratzer et al. Primary hemostasis was studied perfusing an artificial vessel with citrated blood under a constant pressure of 40 mmHg, measuring the blood volume perfused (bleeding volume) and the time until blood flow stopped
Between 1971 and 1990, nine patients ranging in age from 14-38 years received marrow transplants for paroxysmal nocturnal hemoglobinuria (PNH). Six were transplanted for aplastic complications of PNH. Four of these were from HLA-identical siblings, and the patients were conditioned with
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired hemolytic anemia in which a defect of glycophosphatidylinositol (GPI)-anchored proteins in the cell membrane of bone marrow stem cells leads to increased sensitivity of the red cells to complement, causing intravascular hemolysis and
Paroxysmal nocturnal hemoglobinuria is a rare intravascular hemolytic anemia, and thrombosis is the leading cause of mortality rate. The hepatic veins is the common site where Budd-Chiari syndrome usually occurs. We confronted a patient who simultaneously happened to have portal vein and superior
The chromosomes of 14 patients (9 males, 5 females) suffering from paroxysmal nocturnal hemoglobinuria in Merida, Mexico between April 1989 and July 1992 were analyzed. Four of the patients were children (range, 3-15 years old) and 9 were adults (range, 19-62 years old). None of the patients had any
