CARMEN HELENA


SUMMARY OF CARMEN HELENA



INFERIOR VENA CAVA

ITEM TWO: IVC, iliac veins and ascending lumbar vein.



Description, relationships, branches, anastomosis, collateral circulation, variations, changes with age and embryological origin



Description

• Satellite abdominal aorta.

• How common trunk of the veins return infradiaphragmatic.

• Origin: The union of the 2 common iliac veins on the right side of L5.

• Route:

or Abdominal:

 To the right of the lumbar spine
 Vertical
to L1 and then slightly oblique to the right, enter the path to the back of the liver.

or Thoracic:

 After crossing the ring opening of the diaphragm is deflected forward and to the left. 

penetrates the pericardium and turns into the right atrium at the level of T9. Foreign

• Parietal:

or Post: 

• Visceral:

 plexus and intra extrarraquídeos. • Port-

 hemorrhoidal veins.

umbilical anastomosis: 

parietal veins and paraumbilical veins or Anastomosis

Peritoneoparietales:

 Developed in the attached portions of the digestive tract (Root of the mesentery and colon)



Development of Inferior Vena Cava



The IVC is formed by a series of changes in primitive stem veins that occur as the blood, returning from the caudal part of embryo deviates from left to right side of the body. The VCI consists of 4 segments:



• A liver segment derived from the hepatic vein (Part proximal right vitelline vein =, and hepatic sinusoids.

• A prerenal segment of the vein coming subcardinal right.

• A segment from the renal-supracardinal subcardinal anastomosis.
posrrenal
• A segment formed from the vein right supracardinal.



common iliac vein



Description

• They consist of the external and internal iliac veins.

• The two common iliac veins unite in the abdomen at the level of the fifth lumbar vertebra and form the inferior vena cava.

• Drain the territory of the pelvis and lower extremities.

• Both common iliac veins are accompanied along their course by the common iliac arteries. Foreign







• The right iliac is shorter, and then passes posterior lateral homonymous artery.

• The left iliac is more oblique, the posterior and then medial to the artery of the same name. Branches







• Get the iliolumbar vein and sometimes the lateral sacral.

• The left common iliac vein drains the middle sacral veins gathering accompanied the artery.



external iliac vein



Description



• Son las venas grandes que continúan las venas femorales por detrás del canal inguinal.

• Su origen está en el margen inferior de los ligamentos inguinales y terminan cuando se unen a la venas ilíacas internas (para formar las venas ilíacas comunes).

• Ambas venas ilíacas externas son acompañados a lo largo de su curso por el exterior de las arterias ilíacas.



Relaciones

• Continúa a la femoral detrás del ligamento inguinal

• Cursa medialmente a su arteria

• A cada lado esta está cruzada por el uréter y el conducto deferente in man and terete ligament of the uterus and ovarian vessels in women. Branches





• Vena •

inferior epigastric deep circumflex iliac vein



internal iliac vein (hypogastric vein)



Description

• Start near the top of the greater sciatic foramen

• passes upwards and slightly behind medial to the hypogastric artery.

• Attached to the external iliac to form the common iliac vein. Branches





• upper gluteal veins and
lower
• Obturator Veins: Emerge from the obturator canal side wall of the pelvis, passes between the ureter and internal iliac before finishing this.

•
lateral sacral veins
• middle rectal veins: Start rectal plexus, ascend on the upper fascia of diaphragm of pelvis, to the internal iliac.

• bladder veins: drain the vesical plexus in man communicates with the prostatic plexus receiving the deep dorsal vein of the penis, the woman is the deep dorsal vein of the clitoris.

• uterine veins: drain the uterine venous plexus and vaginal venous plexus

• internal pudendal veins: arise from the prostatic plexus in man and woman in the bladder plexus.













ascending lumbar vein









Description



• Vena where the route is through the lateral lumbar spine .

• Structure: The ascending lumbar vein is a structure of pairs.

• Begins in the lateral sacral veins.

• Communicates vertebral plexus

• ascend ahead of the lumbar transverse processes

• Termina en la rama lateral de la ácigos a la derecha, de la hemiacigos a la izquierda allí pueden desembocar las primeras dos lumbares.
