● Review the usefulness of venous volumetric reconstruction of contrast enhanced CT studies for the assessment of venous vascularization of colon adenocarcinoma. ● Assess the usefulness of venous volume reconstruction as "surgical map" for colorectal laparoscopic surgeon. ● Illustrate the correlation between radiological imaging,
surgery with complete excision of the mesocolon and histopathologic analysis cases in our institution.
CT is necessary for preoperative staging in colon adenocarcinoma.
Complete cleavage of the mesocolon containing tumor drainage has showns increase survival and decrease the percentage of locoregional recurrence.
This surgical excision depends on the vascularization that nourishes the tumor. Venous return must be incorporated into the surgical specimen to increase the number of nodes removed and thus facilitate prognosis evaluation and the need for adjuvant chemotherapy. The tumor...
Findings and procedure details
Anatomy and Physiology Venous drainage of the abdominal viscera is produced by a series of veins that end into the portal vein.
Although there are many anatomical variants,
usually the inferior mesenteric vein and splenic vein converge to form the splenomesenteric trunk.
Then this trunk joins the superior mesenteric vein to form the portal vein. In turn,
these major veins are formed by the confluence of minor veins.
the venous system is satellite to the arterial one.
Venous tridimensional reconstruction facilitates the interpretation of the anatomy of venous drainage tumor.
This allows complete cleavage of the mesocolon containing tumor drainage and reduces the incidence of intraoperative complications.
