Peripancreatic arterial anatomy analyzed by 3-dimensional multidetector-row computed tomography

Area of Science:

• Vascular anatomy
• Surgical anatomy
• Medical imaging

Background:

• Peripancreatic vessel anatomy is intricate.
• Accurate preoperative understanding is vital for pancreatoduodenectomy.
• Complex vessel patterns pose surgical challenges.

Purpose of the Study:

• To clarify the complex anatomy of peripancreatic vessels.
• To evaluate the utility of 3D imaging for surgical planning.
• To detail the branching patterns of key peripancreatic arteries.

Main Methods:

• 166 patients underwent multidetector-row computed tomography.
• Peripancreatic vessels were reconstructed in 3D using computer software.
• Analysis focused on the dorsal pancreatic artery and inferior pancreatoduodenal artery (IPDA) branching.

Main Results:

• The dorsal pancreatic artery originated from various sources, most commonly the splenic artery.
• Inferior pancreatoduodenal artery (IPDA) branching showed diverse patterns.
• IPDAs often ran posterior to the superior mesenteric artery (SMA), sometimes obscured by venous tributaries.

Conclusions:

• Peripancreatic vessel anatomy exhibits significant complexity.
• Preoperative 3D arteriography and portography provide precise anatomical information.
• Detailed preoperative imaging aids in planning complex pancreatic surgeries.
