Clinical Anatomy; pelvic mass, prolapse and incontinence Flashcards
What is the ovary suspended on?
Suspended on a mesovarium from the posterior aspect of the broad ligament
Where does the ovary lie in terms of the pelvic side wall?
Ovary lies in the ovarian fossa
What is the relationship of the ovary to the ureter and internal iliac vessels?
Anterior to these
Obturator nerve is lateral to the ovary
What is the arterial supply to the uterus?
Supplied by the uterine artery which are branches of the internal iliac artery
What arteries do the uterine arteries anastomose with?
Ovarian arteries
What is the venous drainage of the uterus?
Internal iliac veins
Ovarian veins
At what aspect will the uterine pass the uterus?
Laterally
Pass above the ureter
Lateral to cervix
Lateral to vaginal fornices
At what vertebral level does the ovarian artery leave the aorta?
L2
In what ligament will the ovarian arteries run?
Broad ligament
What is the name for the part of the broad ligament that acts as mesentery?
Mesosalpinx
What is the relationship of the ovaries to the peritoneum?
Truly intraperitoneal
How can ovarian cancer spread?
Lymphatic drainage
Direct peritoneal spread
What are common sites of ovarian cancer mets?
GI tract
Bladder
Liver
Spleen
Via what lymphatics will ovarian cancer spread?
Pelvic and para-aortic nodes
Will then spread to the supraclavicular (virchow’s) node
Where are the lymph nodes of the pelvis found?
Run alongside: Obturator Internal iliac External iliac Common iliacs Pre-sacral nodes in tissue immediately anterior to sacrum
Where will pelvic lymph converge?
Para-aortic nodes
Where will the para-aortic nodes drain into?
Lumbar trunks
Coalesce to form the cisterna chyli (contains thoracic duct)
Where can the inguinal nodes be found?
Outside fascia lata
Shaped like a T below and parallel to inguinal ligament
Along termination of long saphenous vein
Deep group; medial to femoral vein and in femoral canal
Where will superficial elements of the perineum drain to?
Inguinal nodes
Lymph drainage of rectum?
Sacral and internal iliac
Lymph drainage of anal canal?
Internal iliac
Lower portion to superficial inguinal
Lymph drainage of bladder?
Internal and external iliacs
Lymph drainage of the prostate and proximal urethra?
Internal iliac
Lymph drainage of the distal urethra, penile urethra, penis and clitoris?
Superficial inguinal
Lymph drainage of the testis and ovaries?
Para-aortic
Lymph drainage of uterine tube, uterine fundus, upper uterine body?
Para-aortic
Lymph drainage of lower uterus, cervix and proximal vagina?
Internal and external iliacs
Sacral
Lymph drainage of distal vagina and vulva?
Superficial inguinal
What is the course of the ureter?
Lateral wall behind ovary
Inferior to the uterine artery
Posterior abdominal wall behind branches of superior mesenteric vessels (RHS) and inferior mesenteric vessels (LHS)
Enters bladder wall obliquely at posterolateral corners of trigone
