Abstract

Purpose: Middle cerebral artery (MCA) favors secondaries and emboli deposition. Also, with an increase in incidence of MCA aneurysms, majorly at the M1 division point, actual standardized measurement of MCA is necessary. Thus, main aim of the study is assessment of the MCA morphometry using CT Angiography in Indian population.

Methods: CT cerebral Angiography datasets of 289 patients (180 males and 109 females) were assessed for the MCA morphometry (Average age - 49.29 ± 16.16 years, Range- 11 to 85 years). The cases involving aneurysms and infarcts were excluded. The total length of MCA, length of M1 segment and diameter were measured and the results were statistically analysed.

Results: The mean total length of MCA, length of M1 segment and diameter were 24.02 ± 1.22 mm, 14.32 ± 1.27 mm, 3.33 ± 0.62 mm, respectively. The mean length of M1 segment on the right and left sides was 14.19 ± 1.39 mm and 14.44 ± 1.12 mm, respectively and the difference was statistically significant (p ≤ 0.05). The mean diameter on the right and left sides was 3.32 ± 0.62 mm and 3.33 ± 0.62 mm, respectively and the difference was not statistically significant (p = 0.832). The M1 segment length was maximum in patients over 60 years and diameter was maximum in young patients (20-40 years). The mean length of M1 segment in early bifurcation (4.4 ± 0.65 mm), bifurcation (14.32 ± 1.27 mm) and trifurcation (14.15 ± 1.43 mm) was also noted.

Conclusion: The MCA measurements will be useful for surgeons to minimize errors in handling cases of intracranial aneurysms or infarcts and provide the best possible outcome to the patients.

CT血管造影评价三级医院大脑中动脉形态计量学参数。

目的:大脑中动脉(MCA)有利于继发性和栓塞沉积。此外，随着MCA动脉瘤发生率的增加，主要是在M1分割点，需要对MCA进行实际的标准化测量。因此，本研究的主要目的是利用CT血管造影评估印度人群的MCA形态。方法:对289例患者(男180例，女109例)的CT脑血管造影资料进行MCA形态测定，平均年龄- 49.29±16.16岁，年龄范围- 11 ~ 85岁。排除涉及动脉瘤和梗死的病例。测量MCA总长度、M1段长度和直径，并对结果进行统计学分析。结果:中动脉总长度平均为24.02±1.22 mm, M1段长度平均为14.32±1.27 mm，直径平均为3.33±0.62 mm。左右两侧M1节段平均长度分别为14.19±1.39 mm和14.44±1.12 mm，差异有统计学意义(p≤0.05)。左右两侧平均直径分别为3.32±0.62 mm和3.33±0.62 mm，差异无统计学意义(p = 0.832)。60岁以上患者M1节段长度最大，年轻患者(20-40岁)M1节段直径最大。早期分岔M1节段平均长度(4.4±0.65 mm)，分岔M1节段平均长度(14.32±1.27 mm)，分岔M1节段平均长度(14.15±1.43 mm)。结论:MCA测量将有助于外科医生在处理颅内动脉瘤或梗死病例时减少错误，并为患者提供最好的治疗结果。

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.
