摘要

Purpose

The splenic artery exhibits considerable morphological variability; however, true arterial fenestrations are exceedingly rare within the abdominal vasculature. We report a previously undocumented splenic artery fenestration identified on computed tomography angiography (CTA) in a 70-year-old male.

Anatomic Variation

The artery followed an intrapancreatic course and demonstrated a true fenestration located 33.1 mm from its origin. The fenestrated segment consisted of a superior limb measuring 6.1 mm in diameter and an inferior limb measuring 6.1 mm, with distal reconstitution into a single lumen over a length of 15.4 mm. The finding was consistently visualized using multiplanar reconstructions and three-dimensional volume-rendered CTA images, without evidence of mural irregularity, intimal flap, or arterial dissection.

Conclusions

Recognition of this rare arterial configuration is important for radiologists, surgeons, and interventionalists, as it may mimic arterial duplication or dissection and has potential implications for endovascular and surgical procedures involving the splenic artery.
