hematogenous spread

It is characterized by early hematogenous spread to the lungs.

There are two main ways that a virus is thought to enter the brain via hematogenous spread.

It is thought that the infection is established by hematogenous spread from the gastrointestinal tract.

Hemorrhagic meningitis can result from hematogenous spread of the organism following any form of the disease.

Hematogenous spread appears to be uncommon.

Two main methods of viral entry have been identified: transneuronal spread and hematogenous spread.

Metastasis to dural structures generally occurs by hematogenous spread or direct invasion from a contiguous bone.

Bacteremia is the principal means by which local infections are spread to distant organs (referred to as hematogenous spread).

Because of their rich blood supply, metaphysis of long bones are prone to hematogenous spread of osteomyelitis in children.

Hematogenous spread of the infection into the CNS often occurs after oropharyngeal, dental, or pulmonary infection.

Neoplasia includes the hematogenous spread of systemic tumors, such as breast and lung carcinoma, melanoma, and non-Hodgkin lymphoma.

Bacteria can also use the blood to spread to other parts of the body (which is called hematogenous spread), causing infections away from the original site of infection.

Hematogenous spread, or spread through blood vessels, occur either through the venous plexus of Batson or by arterial dissemination.

OM may occur either because of spread of an adjacent area of infection or by seeding of the infection from a non adjacent site via the blood supply (hematogenous spread).

When the bacilli reach the pulmonary alveoli, they are ingested by alveolar macrophages while other surviving tubercle bacilli multiply within the macrophage and eventually undergo hematogenous spread to other areas of the host body.

Proposed mechanisms for the spread of cancer cells to the umbilicus include direct transperitoneal spread, via the lymphatics which run alongside the obliterated umbilical vein, hematogenous spread, or via remnant structures such as the falciform ligament, median umbilical ligament, or a remnant of the vitelline duct.
