Veins of Head and Neck01:19

Veins 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...
Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Arteries of the Head and Neck01:26

Arteries 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...
Oxygen Delivering System III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Summary

Endovascular aneurysm repair (EVAR) is safe for high-risk abdominal aortic aneurysms with unfavorable anatomy. Commercially available devices, particularly with suprarenal fixation and proximal cuffs, show comparable mid-term durability to standard cases.

Area of Science:

  • Vascular Surgery
  • Medical Devices
  • Aneurysm Treatment

Background:

  • Treatment of abdominal aortic aneurysms (AAAs) with high-risk anatomy (short, angled necks) using commercially available devices is increasing.
  • Institutional experience with endovascular aneurysm repair (EVAR) in these challenging cases is expanding.

Purpose of the Study:

  • To evaluate the durability of approved EVAR devices in patients with short, angled AAA necks (non-Instructions for Use anatomy).
  • To compare outcomes between patients with high-risk anatomy and those with suitable anatomy (IFU).

Main Methods:

  • Retrospective review of 218 patients undergoing EVAR between 2004-2007.
  • Patients were categorized into suitable anatomy (IFU) and high-risk anatomy (non-IFU) groups.
  • Analysis of demographics, operative characteristics, and mid-term outcomes.

Main Results:

  • Non-IFU patients (n=75) had significantly shorter, more angled necks and larger sac diameters compared to IFU patients (n=143).
  • Non-IFU patients required more suprarenal fixation devices and proximal cuffs, with increased fluoroscopy time.
  • Rates of migration, endoleak, reintervention, sac regression, and aneurysm-related death were similar between groups.

Conclusions:

  • EVAR can be safely performed in high-risk patients with unfavorable neck anatomy using specific commercially available endografts.
  • Preferential use of active suprarenal fixation and proximal cuffs is associated with optimal results in these challenging cases.
  • Mid-term outcomes are comparable to patients with suitable anatomy, but long-term follow-up is essential.
