While most of the tumor was intravascular, there was also significant extravascular
Determining whether a sarcoma is of primary intravascular origin versus extravascular
origin from a retroperitoneal mass that invades the vessel secondarily, is of paramount importance in guiding appropriate treatment and determining prognosis.
Hemolysis is classified as either intravascular, occurring within the blood vessels, or extravascular
, mediated by phagocytic destruction in the reticuloendothelial system.
Histopathological examination showed normal epidermis and mild edema, extravascular
erythrocytes, and non-specific inflammatory cell infiltration in the dermis.
From a pathological perspective, inflammation is a process driven by inflammatory cells responding to signals and is "the reaction of blood vessels leading to the accumulation of fluid and leukocytes in extravascular
22,23) Because the routes of administration cited are extravascular
, higher dosages may be required to achieve similar plasma concentrations.
Following this pathological process, the plasmocytes and the red blood cells migrate to the extravascular
space and vasogenic edema occurs (21).
Albumin is the major protein in serum and is present typically at around 50 mg/mL, where it makes up around 60% of the total protein; approximately 60% of which s in the extravascular
the market segment leader in extravascular
closure devices, announced today an exclusive agreement with Biosensors International for the distribution of the Mynx(TM) Vascular Closure Device throughout the United Kingdom, Switzerland and France.
Application of phytononine for 3 weeks resulted in a 24% decline in the redness of the affected area and a 25% reduction of extravascular
blood flow, helping to improve the appearance of redness and broken capillaries.
SA is consistently decreased in PE, the patients thus manifesting decreased oncotic pressure resulting in more intravascular fluid entering or remaining in the extravascular
Extravasation refers to the escape of a chemotherapy drug into the extravascular
space, either by leakage from a vessel or by direct infiltration.
Aneurysm of extravascular
origin arise because of local extension of infection followed by invasion of large arteries commonly associated with middle ear disease, cavernous sinus thrombophlebitis, meningitis, adjacent osteomyelitis of the skull, sinus infection, or postoperative infection.
Other intravascular and extravascular
pathologic findings were frequently present, including fibrin thrombi and perivascular ring hemorrhages (Figure 8).
There have been studies indicating lack of macroprolactin in the pituitary tissue and in the extravascular
space (cerebrospinal fluid) (35).
