Summary
This study introduces a four-type classification for the costocervical trunk (CCT) anatomy based on 75 CTAs. The common Type 1 CCT was observed in 76.1% of cases, with absence noted in 23.94%.
Area of Science:
- Anatomy
- Vascular Anatomy
- Medical Imaging
Background:
- The anatomy and prevalence of the costocervical trunk (CCT) are not well-documented.
- Variations in CCT anatomy can impact endovascular procedures in the cervical region.
Purpose of the Study:
- To classify the branching patterns and morphometric properties of the costocervical trunk (CCT).
- To propose a novel four-type classification system for CCT anatomy based on computed tomography angiography (CTA) findings.
Main Methods:
- Retrospective analysis of 75 costocervical trunks (CCTs) from 55 patients who underwent neck and thoracic CTA.
- Detailed examination of branching variations and morphometric properties of each CCT.
Main Results:
- A novel four-type classification system for CCT branching patterns was established.
- Type 1, consistent with anatomical literature, was the most prevalent (76.1%).
- The costocervical trunk (CCT) was absent in 23.94% of the analyzed cases.
Conclusions:
- The proposed four-type classification system enhances understanding of CCT anatomical variability.
- Knowledge of CCT variations is crucial for surgeons performing endovascular procedures in the neck and thoracic regions.

01:16Spinal Cord: Cross-sectional Anatomy
2.3K
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:30General Structure of a Vertebra
3.3K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

3.7K
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...

01:23Spinal Nerves: Anatomy
4.0K
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

01:27Muscles of the Vertebral Column
1.9K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

01:28Articulations of the Vertebral Column
2.1K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
