It is located in the extraperitoneal space
of Retzius, which is bounded by the parietal peritoneum posteriorly and the tranversalis fascia anteriorly.
We postulate that insufflation of the extraperitoneal space
caused bleeding which tracked down through the femoral canal, opening it up and allowing herniation of pre-peritoneal fat.
One week after the 2004 ICD was placed in the extraperitoneal space
of the man's abdomen, he developed a wound dehiscence near the center of the incision site.
In the first few weeks after transplantation, perinephric fluid collections may be seen, usually in the extraperitoneal space
CTE can assess for the presence of penetrating disease, detecting sinus or fistula tracts extending from the diseased segment that are commonly characterized by bowel tethering and visualization of linear tracts that may communicate with adjacent structures, such as bowel or extraperitoneal spaces
(most commonly entero-enteric, entero-colic, entero-cutaneous) (Figures 8 and 9).
