Summary
The gastrocolic venous trunk, crucial for surgical planning, shows high occurrence and variability in formation. Understanding its anatomy via CT scans aids in diagnosing splenic thrombosis and planning surgeries for liver or pancreatic conditions.
Area of Science:
- Anatomy
- Vascular Anatomy
- Medical Imaging
Background:
- The gastrocolic venous trunk's anatomy is vital for surgical procedures involving the upper abdomen.
- Variations in its formation can impact surgical outcomes and diagnostic accuracy.
Purpose of the Study:
- To investigate the formation, measurements, and frequency of the gastrocolic venous trunk.
- To evaluate the utility of computed tomography (CT) in assessing this venous structure.
Main Methods:
- Injection-corrosion technique on 54 anatomic specimens.
- Analysis of CT studies in 50 patients without hepatic or pancreatic disease.
Main Results:
- The gastrocolic trunk was identified in 94.4% of anatomic specimens and 54% of CT studies.
- Significant variability in its formation (bipodal, tripodal, quadripodal) was observed.
- Mean diameter was 4.9 mm, typically draining into the superior mesenteric vein.
Conclusions:
- The gastrocolic venous trunk is frequently encountered, with diverse formation patterns.
- Preliminary CT assessment is valuable for pre-operative planning in portal hypertension, pancreatic tumors, and splenic thrombosis diagnosis.
