Presacral space

Fig. 1.2a-

Posterior tumor growth leads to infiltration of the presacral space and sacral bone or of the perirectal space and rectum. Recurrent cervical cancer is associated with rectal infiltration in about 17% of cases. The most common site is the rectosigmoid junction. Laterally, recurrent tumor may extend to the pelvic sidewall. If the recurrent local tumor grows anteriorly along the peritoneal fold, there will be infiltration of the urinary bladder. Advanced recurrent cervical cancer may involve the remaining colon or the small intestine and is typically associated with adhesion of bowel loops and may cause intestinal obstruction. 

Our option Small space between presacral fascia and sacral and coccygeal vertebrae containing vessels... 

What is situated outside the rectal fascia and therefore outside the perirectal subcompartment Dorsally, the presacral subcompartment is loosely attached to the perirectal compartment (see above). Laterally the supplying structures (autonomic nerves and branches of the iliac vessels) of the urogenital organs constitute a nerve-vessel plate (Fig. 1.3c). The latter is accompanied by connective tissue and fills the remaining space between the perirectal compartment...
