Summary
A sufficient infrarenal aortic neck is crucial for successful endovascular repair of aortic aneurysms (EVAR). Proper pre-operative evaluation of the proximal neck anatomy ensures better long-term outcomes.
Area of Science:
- Vascular Surgery
- Medical Imaging
- Biomedical Engineering
Background:
- A sufficient infrarenal aortic neck is vital for successful endovascular aneurysm repair (EVAR).
- Proximal neck morphology significantly impacts EVAR outcomes.
- Challenges in proximal anatomy require advanced imaging techniques.
Purpose of the Study:
- To review literature on proximal neck morphology's influence on long-term EVAR outcomes.
- To discuss associations between endograft characteristics and proximal neck sealing.
- To highlight the importance of pre-operative planning for EVAR success.
Main Methods:
- Literature review on infrarenal aortic neck morphology and EVAR.
- Analysis of dynamic imaging and center lumen line reconstructions.
- Discussion of endograft features and proximal sealing.
Main Results:
- Proximal neck characteristics (length, angulation, shape, thrombus, calcification) are key to EVAR success.
- Dynamic imaging aids in planning complex proximal anatomies.
- Endograft selection and proximal neck sealing influence long-term results.
Conclusions:
- Thorough pre-operative assessment of the infrarenal aortic neck is essential for successful EVAR.
- Advanced imaging techniques improve planning in challenging cases.
- Understanding the interplay between neck morphology and endograft design is critical for optimal sealing and durability.

01:26Muscles of the Anterior Neck
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
01:25Physiological Barriers
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

01:19Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:22Esophageal Perforation-I: Introduction
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus.

01:19Anastomoses
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
