Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, after aneurysms of the abdominal aorta and iliac arteries. [2] [3] They may occur in pregnant women in the third trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70 to 90%.
Splenic infarction is a condition in which blood flow supply to the spleen is compromised, [1] leading to partial or complete infarction (tissue death due to oxygen shortage) in the organ. [2] Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot .
Small aneurysms (less than 7 mm) have a low risk of rupture and increase in size slowly. [44] The risk of rupture is less than one percent for aneurysms of this size. [44] The prognosis for a ruptured cerebral aneurysm depends on the extent and location of the aneurysm, the person's age, general health, and neurological condition. Some ...
Open surgery has a high morbidity and mortality. Recent advances over the past few decades have made endovascular embolization the preferred method of treatment. These treatments are preferred because they offer little threat to the surrounding brain tissue. However, there have been several reported cases of arteriovenous malformations ...
Approximately 4 percent of aneurysmal bleeds occur after sexual intercourse and 10 percent of people with SAH are bending over or lifting heavy objects at the onset of their symptoms. [11] Overall, about 1 percent of all people have one or more cerebral aneurysms. Most of these are small and unlikely to rupture. [52]
Enlargement of the spleen is a requirement for the diagnosis of SMZL and is seen in nearly all people affected by SMZL (often without lymphadenopathy). [1] Aside from the uniform involvement of the spleen, the bone marrow is frequently positive in patients with SMZL displaying a nodular pattern with morphology similar to what is observed in the splenic hilar lymph nodes. [7]
Traumatic rupture of the spleen on contrast enhanced axial CT (portal venous phase) Splenic hematoma resulting in free abdominal blood. Splenic rupture is usually evaluated by FAST ultrasound of the abdomen. [5] Generally this is not specific to splenic injury; however, it is useful to determine the presence of free floating blood in the ...
Splenomegaly can result in hematologic disturbances and abdominal pain and can increase the risk for splenic rupture, which also causes spleen pain, from blunt trauma, resulting in life-threatening internal bleeding. [2] Many conditions can cause splenomegaly, such as various infections, liver disease, and cancer. [2]
