Multi-detector row CT accurately assessed splenic volume, vascular anatomy, and lesions before laparoscopic splenectomy. This imaging technique provides reliable pre-operative information for surgical planning.

Area of Science:

  • Radiology
  • Surgical Imaging
  • Abdominal Imaging

Background:

  • Laparoscopic splenectomy requires detailed pre-operative assessment of splenic anatomy.
  • Accurate splenic volume and vascular mapping are crucial for successful surgical planning.

Purpose of the Study:

  • To evaluate multi-detector row spiral computed tomography (CT) for determining splenic volume, vascular anatomy, and detecting accessory spleens and parenchymal lesions.
  • To assess the accuracy and reproducibility of CT in patients undergoing laparoscopic splenectomy.

Main Methods:

  • Twenty-two patients underwent multiphasic multi-detector row CT.
  • Splenic volume was assessed by two observers using two editing modalities, with reliability calculated using Cronbach's alpha.
  • CT angiography evaluated splenic vascular anatomy, accessory spleens, and parenchymal lesions.

Main Results:

  • Both CT editing modalities showed high inter-observer reliability (alpha > 0.99) and accurately predicted specimen weight (R2 > 0.99).
  • CT angiography precisely depicted splenic vascular anatomy, including polar arteries.
  • Multi-detector row CT successfully identified all accessory spleens and parenchymal lesions.

Conclusions:

  • Multi-detector row CT provides accurate and reproducible volumetric and anatomic evaluation of the spleen.
  • This imaging modality is valuable for pre-operative assessment in patients undergoing laparoscopic splenectomy.
