Abstract
Purpose: The objective of this research was to analyze and correlate the length of the left main coronary artery (LMCA) with significant clinical parameters using multi-slice CT (MSCT).
Materials and methods: 1500 patients (851 males and 649 females; mean age 57.38 ± 11.03 [SD]; age range: 5-85 years) who underwent MSCT scans from September 2020 to March 2022 were retrospectively included. The data were applied to generate three-dimensional (3D) simulations of a coronary tree using the syngo.via post-processing workstation. The reconstructed images were then interpreted, and the collected data were subjected to statistical analysis.
Results: The results showed 1206 (80.4%) cases with medium LMCA, 133 (8.9%) with long LMCA, and 161 (10.7%) with short LMCA. The average diameter of LMCA at its midpoint was 4.69 ± 0.74 mm. The most frequent type of division of LMCA was bifurcation in 1076 (71.7%) cases; in 424 (28.3%) cases, the LMCA was divided into three or more branches. The dominance was right in 1339 (89.3%), left in 78 (5.2%), and co-dominant in 83 (5.5%) cases. There was a positive correlation between the length and branching patterns of LMCA, χ2 = 113.993, P = 0.000 (< 0.05). Other variables like age, sex, diameter of LMCA, and coronary dominance did not show any significant correlation.
Conclusion: This study has demonstrated a significant association between the length and the branching pattern of LMCA, which may be essential in diagnosing and treating coronary artery patients.
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.
