2) CNS involvement (uncommon in travelers), is due to embolization of eggs from the portal mesenteric system via the paravertebral venous plexus
The vertebral venous plexus
is a valveless system which communicates directly with pelvic, sacral, intercostal, azygos, caval and intracranial veins (1).
SUMMARY: The vertebral venous plexus
in dogs is ah extensive vascular network that extends along the entire length of the vertebral column.
The Batson venous plexus
was first suggested to play an unrecognized role in vertebral metastases from prostatic carcinoma.
When a patient has extensive bleeding in the presacral area from the presacral venous plexus
After laminectomy at the appropriate level, the dura was opened and, under the operating microscope, the enlarged vein filled with arterialized blood which bridged the subarachnoid space from the dura to the coronal venous plexus
was coagulated and divided.
brand name, and Orthofix's A-V Impulse System(R), a venous plexus
Furthermore, the fragility of epidural venous plexus
is responsible for increasing bleeding tendency.
The needle is then advanced until it terminates near the center of the vertebral body, no more than one half to two-thirds of the anterior-posterior (AP) dimension of the vertebral body, taking care to avoid breaching the ventral vertebral body cortex into the overlying anterior external venous plexus
3,4) We report a rare case of pulmonary mucormycosis presenting with acute myelitis and showing spinal cord and vertebral body infarction probably due to air embolism along the venous plexus
of the spinal cord.
Lumbar veins drain blood from the abdominal wall and vertebral venous plexus
into the inferior vena cava, ascending lumbar veins, renal veins, or lumbar azygous vein.
6) and multiple collaterals draining into the retroperitoneal venous plexus
