Exposing Brachial Plexus: A Surgical Technique to Visualize Brachial Plexus in Neonatal Piglet
0 Views •
2025
This video describes an in vivo surgical procedure to expose the brachial plexus, a neural network that supplies cutaneous and muscular interventions to the upper limb. This surgery helps locate the plexus and eventually assess the extent of nerve injury involving the upper limb.

Source: Rennert, R. C., et al. Comprehensive Endovascular and Open Surgical Management of Cerebral Arteriovenous Malformations. J. Vis. Exp. (2017).This video demonstrates the open surgical resection of a cerebral arteriovenous malformation (AVM) in a human brain. The procedure involves creating a bone flap, accessing the subarachnoid space, identifying and occluding feeding arteries and draining veins, and carefully removing the AVM. Intraoperative angiography confirms complete resection,...

FAQs
They provide complementary information rather than relying on a single view. Operating microscopes and endoscopes offer direct optical observation, while neuronavigation relates the operative field to preoperative scans. Fluorescence-guided imaging adds tissue-specific signals, helping surgeons interpret anatomical structures, spatial relationships, and tissue differences during procedures. This combination supports more informed decisions while limiting unnecessary disruption.
Contrast helps distinguish structures that may otherwise appear similar. Fluorescence-guided imaging uses tissue-specific signals, whereas optical systems show the operative field directly and imaging or navigation technologies add anatomical and spatial information. Together, these sources can help differentiate tumors, blood vessels, brain regions, and functional tissue, which is important when surgeons must work near sensitive structures.
Neuronavigation connects the surgeon’s real-time operative view with preoperative scans, providing spatial orientation that direct visualization alone may not supply. Microscopes and endoscopes show the field through optical perspectives, while navigation helps relate visible anatomy to the broader recorded anatomy. This combined information is particularly relevant for targeting deep or anatomically complex regions during neurosurgical intervention.
The choice depends on the anatomical view and information required during the operation. Operating microscopes support detailed optical observation, while endoscopes can provide an alternative visual approach. Neuronavigation contributes spatial orientation from preoperative scans, and fluorescence-guided imaging highlights tissue-specific signals. Using these technologies together can support tumor resection, vascular repair, and deep-brain interventions.
During tumor resection, enhanced contrast can help surgeons distinguish tumor tissue from brain regions and functional tissue. In vascular repair, detailed views of blood vessels and their relationships to nearby structures support accurate clinical decisions. The same visualization principles also assist deep-brain interventions, where spatial orientation and preservation of surrounding anatomy are especially important.
Three-dimensional imaging and augmented reality extend visualization beyond a conventional direct view by strengthening spatial understanding of anatomy. When combined with operative views and preoperative scans, they can help represent relationships among brain regions, vessels, tumors, and functional tissue. These developing approaches are intended to improve precision and support safer clinical decisions during neurosurgical procedures.
