The Arch of Aorta

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

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...

Area of Science:

Neurosurgery
Interventional Neuroradiology
Vascular Neurology

Background:

Supratentorial arteriovenous malformations (AVMs) in eloquent territories pose significant surgical challenges.
Resection of these AVMs can be complex due to their location near critical neural pathways.

Purpose of the Study:

To present the multimodality treatment of a symptomatic 3-cm arteriovenous malformation in the left motor strip.
To illustrate the benefits of preoperative embolization in reducing microsurgical risks.

Main Methods:

Preoperative angiography to assess the need for embolization.
Multimodality treatment involving embolization and microsurgery.
Selective choice of embolysate based on surgeon's discretion.

Main Results:

Reduced microsurgical risk through early venous occlusion.
Decreased intraoperative hemorrhage.
Minimized pial dissection near the corticospinal tract.

Conclusions:

Multimodality treatment is effective for complex supratentorial AVMs in eloquent territories.
Preoperative embolization is a valuable adjunct to microsurgery, enhancing safety and efficacy.
Careful selection of embolysate is a key consideration in the treatment strategy.
