What is the Basivertebral vein?

The basivertebral veins are veins within the vertebral column. They are contained in large, tortuous channels in the substance of the bones, similar in every respect to those found in the diploë of the cranial bones. They emerge from the foramina on the posterior surfaces of the vertebral bodies.

What is Batsons plexus?

Batson’s venous plexus is a system of paravertebral veins that connect pelvic and thoracic vessels to the intraspinal (basivertebral) veins. It was first described in 1940 to explain a route for spread of metastases and infection that was separate to the lymphatic system.

What is Suboccipital plexus?

The suboccipital venous plexus drains deoxygenated blood from the back of the head. It communicates with the external vertebral venous plexuses. … The occipital vein joins in the formation of the plexus deep to the musculature of the back and from here drains into the external jugular vein.

Where is Batsons plexus located?

vertebral column Batson’s plexus of veins is a complicated valveless network of veins located near the vertebral column. In normal conditions, it provides venous drainage of the brain and spine; in pathological conditions, it allows dissemination of infections and cancer.

Where is the Basivertebral nerve?

What is the Basivertebral Nerve? The basivertebral nerve enters the vertebral bodies of the spinal column. Within the vertebral body, the nerve branches and supplies the endplates or the upper and lower surfaces of the vertebral body.

What is prominent venous plexus?

The anterior internal vertebral venous plexus is more prominent and largely lies posterior to the vertebral bodies, while the posterior internal vertebral venous plexus largely lies anterior to the laminae.

What is the function of the venous plexus?

The plexus is also structurally connected to the superior rectal vein. The veins in the plexus work by transporting oxygen-depleted blood from the uterus and carrying it back to the heart.

What is a venous plexus?

A venous plexus is a congregation of multiple veins.

What veins flow into Azygos?

The azygos vein is a vein running up the right side of the thoracic vertebral column draining itself towards the superior vena cava. …

Where does the Suboccipital nerve come from?

Course: The suboccipital nerve is the dorsal ramus of the first cervical nerve. It emerges from the central canal to travel between the posterior arch of C1 inferiorly and the vertebral artery superiorly.

What is in the Suboccipital triangle?

The suboccipital triangle is a region of the neck bounded by the following three muscles of the suboccipital group of muscles: Rectus capitis posterior major – above and medially. Obliquus capitis superior – above and laterally. Obliquus capitis inferior – below and laterally.

Where is the Suboccipital venous plexus?

The suboccipital venous plexus is situated between the occipital bone and the atlas. it communicates with the external vertebral venous plexuses.

Where does prostatic venous plexus drain?

internal iliac veins The receipt of blood from the vesical and prostatic rami connect the prostatic plexus to the vesical plexus and internal pudendal vein. The prostatic plexus then drains into the vesical and internal iliac veins.

How does the Pampiniform plexus regulate temperature?

The pampiniform plexus helps regulate the temperature of the testes by acting as a “heat exchange” mechanism to cool down the blood. The arteries supplying the testes run through the plexus where the blood is cooled from abdominal arterial temperature to testicular temperature.

What does the intervertebral vein drain into?

The function of the vertebral vein is to drain the venous blood from the cervical spine, prevertebral and suboccipital muscles. It terminates low in the neck by emptying into the brachiocephalic vein.

What does the basivertebral nerve do?

The vertebral endplates contain a rich nerve supply stemming from the basivertebral nerve that transmits pain from the superior and inferior endplates. Studies have found that there are endplate changes associated with disk degeneration.

What is BVN ablation?

If conservative treatments fail to deliver the relief you desire from your low back pain, basivertebral nerve (BVN) ablation can be an effective option. This treatment uses radiofrequency energy to heat the BVN, thereby stopping the nerve from sending pain signals.

Who performs intracept procedure?

Spine surgeons and interventional pain specialists perform the Intracept Procedure under image guidance in the outpatient setting, with the entire procedure taking 60-90 minutes. Treated patients report nearly immediate relief of their back pain.

What are the symptoms of pelvic congestion syndrome?

Symptoms

  • Pelvic pain that worsens as the day goes on, particularly if much time is spent standing.
  • Pelvic pain that worsens during menstruation, after sex, or after certain physical activities.
  • Swollen vulva.
  • Varicose veins in the genital region or legs.
  • Hemorrhoids.
  • Low back pain.
  • Vaginal discharge.
  • Abnormal vaginal bleeding.

What causes venous engorgement?

Vein Engorgement In Athletes Superficial veins in the lower legs and arms often become engorged when the limb is injured or overused; often long after the original injury has taken place. The injury can create the formation of a blood clot deep in muscle tissue where it can go undetected for a period of time.

What is venous obstruction?

Venous obstruction is partial or complete occlusion of the lumen of a vein. It can lead to decreased venous flow and increased blood pooling. Venous stasis results in increased viscosity and the formation of microthrombi which may be caused by anything that slows or obstructs the flow of venous blood.

Which plexus drains the bladder?

Which plexus drains the uterus?

uterine venous plexus 9.1. In humans, the uterus is drained via the uterine vein. The uterine veins form a uterine venous plexus on each side of the cervix. Veins from the uterine plexus drain into the internal iliac veins.

Which plexus drains the ovaries?

pampiniform plexus In females, the pampiniform plexus drains the ovaries. The right ovary drains from the plexus to the ovarian vein and then to the inferior vena cava.

What is meant by Venae Comitantes?

Medical Definition of vena comitans : a vein accompanying an artery The accompaniment is so complete, in fact, that for much of the route up the arm, the vein network forms true venae comitantes, or parallel paired veins on either side of the artery.—

What is azygos lobe of lung?

The azygos lobe, also commonly referred to as an accessory lobe of the azygos vein, is located at the apicomedial portion of the right lung and is separated from the remainder of the upper lobe by a fissure. It usually has no significant clinical implications and is an incidental finding in radiographic studies.

Where does the azygos vein start?

The azygos vein originates at the junction of the right ascending lumbar and subcostal veins, entering the chest through the aortic hiatus. It ascends along the anterolateral surface of the thoracic vertebrae and arches ventrally to the right main bronchus at T5–T6, draining into the SVC.

Does azygos vein have valves?

The azygos vein contains a valve halfway along the azygos arch (between the vertical azygos vein and the point where the azygos vein enters the SVC). This valve is a common place for the intravenously injected contrast agent to accumulate, which may simulate pathology on CT 3.
