Abstract

Objective: The purpose of the study was to analyze the anatomy and variations in the origin of the dorsal pancreatic artery, greater pancreatic artery and to study the various types of arterial arcades supplying the pancreas on multidetector CT (MDCT).

Methods: A retrospective analysis of 747 MDCT scans was performed in patients who underwent triple phase or dual phase CT abdomen between December 2020 and October 2022. Variations in origin of Dorsal pancreatic artery (DPA), greater pancreatic artery (GPA), uncinate process branch were studied. Intrapancreatic arcade anatomy was classified according to Roman Ramos et al. into 4 types-small arcades (type I), small and large arcades (type II), large arcades (type III) and straight branches (type IV).

Results: The DPA was visualized in 65.3% (n = 488) of cases. The most common origin was from the splenic artery in 58.2% (n = 284) cases. The mean calibre of DPA was 2.05 mm (1.0-4.8 mm). The uncinate branch was seen in 21.7% (n = 106) with an average diameter of 1.3 mm. The greater pancreatic artery was seen in 57.3% (n = 428) predominantly seen arising from the splenic artery. The most common arcade anatomy was of Type II in 52.1% (n = 63) cases.

Conclusion: Pancreatic arterial variations are not very uncommon in daily practice. Knowledge of these variations before pancreatic surgery and endovascular intervention procedure is important for surgeons and interventional radiologist.

胰背动脉和胰内窦解剖的MDCT评估。

目的：分析胰腺背动脉、胰腺大动脉起源的解剖学和变异，并在多层螺旋CT（MDCT）上研究供应胰腺的各种动脉弓。方法：对2020年12月至2022年10月期间接受腹部三期或双期CT扫描的747例患者进行了MDCT扫描的回顾性分析。研究了胰背动脉（DPA）、胰大动脉（GPA）、钩突支起源的变化。根据Roman Ramos等人将胰内拱廊解剖分为4类：小拱廊（I型）、大小拱廊（II型）、大拱廊（III型）和直枝（IV型）。结果：DPA显示率为65.3%（n = 488）例。最常见的起源于脾动脉58.2%（n = 284）例。DPA的平均口径为2.05mm（1.0-4.8mm），钩支占21.7%（n = 平均直径为1.3mm。57.3%（n = 428），主要见于脾动脉。最常见的拱廊解剖为II型，占52.1%（n = 63）例。结论：胰腺动脉变异在日常实践中并不罕见。在胰腺手术和血管内介入手术之前了解这些变化对外科医生和介入放射科医生来说很重要。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
