Summary
Developing diagnostic angiography algorithms is crucial for planning craniofacial tumor (CFT) surgeries. This study outlines a method to assess tumor blood supply, aiding surgeons in complex cases and minimizing blood loss.
Area of Science:
- Neurosurgery
- Radiology
- Vascular Imaging
Background:
- Craniofacial tumors (CFTs) present complex vascular challenges due to their spread.
- Surgical removal of CFTs often results in significant blood loss.
- Accurate preoperative assessment of tumor blood supply is vital for surgical planning.
Purpose of the Study:
- To develop a diagnostic angiography algorithm for planning surgical treatment of craniofacial tumors.
- To optimize preoperative imaging strategies for CFT patients.
Main Methods:
- Complex preoperative angiography performed in 72 CFT patients (age 10-78).
- Quantification of tumor blood supply using SCT perfusion.
- Application of direct, 3D TOF HR MR, or SCT angiography based on tumor vascularization.
Main Results:
- Preoperative embolization of accessible afferents in 12 hypervascular tumors via external carotid artery.
- Observed increased tumor blood supply through alternative routes after embolization.
- Data informed surgical approach planning; no significant correlation found between SCT perfusion and endothelial markers.
Conclusions:
- Comprehensive assessment of craniofacial tumor blood supply is essential for surgical planning.
- Developed algorithms for preoperative angiographic diagnosis based on clinical and radiological data.
- Improved surgical planning for craniofacial tumors through advanced imaging techniques.

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...

01:19Veins of Head and Neck
6.1K
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...

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.

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:29Blood and Nerve Supply to the Bones
14.2K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
