摘要

目的:枕动脉(OA),通常起源于颈外动脉(ECA),通常在向颅底上升时深入二腹肌后腹。虽然非洲经委会起源高度的变化是已知的,但OA的异常过程以前没有记录。方法:本研究通过回顾性分析存档的4例CT血管造影,包括3例女性和1例男性患者,年龄在57至66岁之间。结果:在两例病例中,我们观察到OA通过颈内静脉而不是其通常的浅表轨迹;这些变体位于左侧。在其余两例中,骨性关节炎表现为腮腺深处的下颌后病变。其中一例显示双侧OA的下颌后节段,另一例显示一共同的枕耳干,起源于腮腺间隙内的右侧颞浅动脉,随后分为耳后动脉和OA。结论:这些以前未报道的解剖变异在临床上具有重要意义,在涉及腮腺区域的手术或介入性手术中应予以考虑。

Aberrant courses of the occipital artery.

Purpose: The occipital artery (OA), typically arising from the external carotid artery (ECA), usually courses deep to the posterior belly of the digastric muscle as it ascends toward the skull base. While variations in the height of origin from the ECA are known, aberrant courses of the OA have not been previously documented.

Methods: This study presents a four-case series identified through retrospective analysis of archived CT angiograms involving three female and one male patient, aged between 57 and 66.

Results: In two cases, the OA was observed to pass deep to the internal jugular vein instead of its usual superficial trajectory; these variants were located on the left side. In the remaining two cases, the OA demonstrated aberrant retromandibular courses deep within the parotid glands. One of these cases revealed bilateral retromandibular segments of the OA, while the other exhibited a common occipitoauricular trunk originating from the right superficial temporal artery within the parotid space, which subsequently divided into the posterior auricular artery and the OA.

Conclusion: These previously unreported anatomical variations are clinically significant and should be considered during surgical or interventional procedures involving the parotid region.

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.
