Insights

A new technique allows selective catheterization of the meningohypophyseal trunk (MHT) and its branches. Accessing the MHT via an ipsilateral approach is challenging due to its orientation with the internal carotid artery.

Area of Science:

  • Vascular neurosurgery
  • Interventional neuroradiology
  • Cerebral angiography

Background:

  • The meningohypophyseal trunk (MHT) is a critical vessel supplying the pituitary gland and cavernous sinus.
  • Selective catheterization of the MHT is essential for targeted therapies like embolization.
  • Existing techniques face challenges due to the complex anatomy and vessel orientation.

Observation:

  • A novel technique for selective catheterization of the MHT and its branches is presented.
  • The study highlights the inherent difficulties associated with an ipsilateral approach to the MHT.
  • Specific anatomical considerations regarding the MHT's relationship to the internal carotid artery are emphasized.

Findings:

  • Successful selective catheterization of the meningohypophyseal trunk (MHT) and its branches was achieved using the described novel technique.
  • The geometric orientation of the MHT relative to the parent internal carotid artery presents a significant challenge for ipsilateral access.
  • The technique aims to overcome these anatomical hurdles for improved procedural success.

Implications:

  • This novel technique may improve the safety and efficacy of endovascular treatments targeting the MHT.
  • Enhanced understanding of MHT anatomy and access strategies can benefit neurosurgeons and interventional neuroradiologists.
  • Potential for improved patient outcomes in conditions requiring MHT intervention, such as pituitary adenomas and dural arteriovenous fistulas.

The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

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...

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...
