Cats are one of the most common companion animals, and they differ from dogs in several important ways. Considering the central importance of anatomy in high-quality medicine, the treatment of the feline mandible, mostly during intraoral procedures requiring general anaesthesia, has many important features. In cats, the major artery of the brain is the maxillary artery that forms unique structure - the rete mirabile. The rete mirabile is a plexus like vascular structure that lies extracranially and communicates with brain arterial circle through the orbital fissure. The development of the brain vasculature is different in cats, and it includes obliteration mechanisms of the internal carotid artery. The course of the maxillary artery that forms the rete mirabile has a strong relationship to the angular process of the mandible. Emphasis should be placed on manipulation with the feline mandible, especially during open-mouth procedures, as mistakes can lead to blindness, deafness, and central neurological disorders due to compression of the maxillary artery by the angular process of the mandible. This paper focuses on the anatomy and function of the blood supply to the brain, which is very specific in domestic cats and other felids.
猫是最常见的伴侣动物之一，它们在几个重要方面与狗不同。考虑到解剖学在高质量医学中的核心重要性，猫下颌骨的治疗，主要是在需要全身麻醉的口腔内手术中，具有许多重要特征。在猫中，大脑的主要动脉是上颌动脉，它形成了独特的结构——网状奇迹。网状奇迹是一种类似丛的血管结构，位于颅外，并通过眶裂与脑动脉环沟通。猫的脑血管发育不同，包括颈内动脉的闭塞机制。形成网状奇迹的上颌动脉的行程与下颌角突有很强的关系。应该特别注意对猫下颌骨的操作，特别是在张口手术中，因为错误会导致由于下颌角突对上颌动脉的压迫而导致失明、耳聋和中枢神经系统紊乱。本文重点介绍大脑血液供应的解剖学和功能，这在家猫和其他猫科动物中非常特殊。
