The quadrigeminal cistern [1] (also cistern of great cerebral vein, [1] vein of Galen cistern, [2] superior cistern, [2] [3] Bichat's canal, [3] or peripineal cistern [2]) is a subarachnoid cistern situated between splenium of corpus callosum, and the superior surface of the cerebellum.
Most arachnoid cysts are asymptomatic, and do not require treatment. Where complications are present, leaving arachnoid cysts untreated may cause permanent severe neurological damage due to the progressive expansion of the cyst(s) or hemorrhage (bleeding). [2] However, with treatment most individuals with symptomatic arachnoid cysts do well.
Each ambient cistern extends anterolaterally around the mesencephalon to become continuous rostrally/anteriorly with the interpeduncular cistern. [2] Each ambient cistern is continuous dorsally/posteriorly with the quadrigeminal cistern; [3] [4] inversely, each ambient cistern is an anterolateral extension of the quadrigeminal cistern on either side [2] (some sources define the quadrigeminal ...
Treatment is by prompt neurosurgery or radiologically guided interventions with medications and other treatments to help prevent recurrence of the bleeding and complications. Since the 1990s, many aneurysms are treated by a minimal invasive procedure known as endovascular coiling , which is carried out by instrumentation through large blood ...
Interpeduncular cistern. It is situated at the base of the brain, between the two cerebral peduncles of midbrain and dorsum sellae and continuous below with the pontine cistern and superiorly with the chiasmatic cistern. It contains: The optic chiasm; The bifurcation of the basilar artery; Peduncular segments of the posterior cerebral arteries ...
Damage control surgery is surgical intervention to keep the patient alive rather than correct the anatomy. [ 1 ] [ 2 ] It addresses the "lethal triad" for critically ill patients with severe hemorrhage affecting homeostasis leading to metabolic acidosis , hypothermia , and increased coagulopathy .
In medicine , bleeding diathesis is an unusual susceptibility to bleed mostly due to hypocoagulability (a condition of irregular and slow blood clotting), in turn caused by a coagulopathy (a defect in the system of coagulation).
The cistern contains the middle cerebral artery (MCA) [2] and its branches, [4] and the two (i.e. superficial and deep) middle cerebral veins (MCVs). [ 2 ] The cistern is subdivided into three compartments: the superficial opercular compartment (SOC) (most superficial), deep opercular compartment (DOC) (intermediate), and cisternal compartment ...
