Summary
Endoscopic visualization and clipping of cerebral aneurysms are feasible with current technology. The penscope facilitates instrument access for managing ruptures during minimally invasive aneurysm surgery.
Area of Science:
- Neurosurgery
- Minimally Invasive Surgery
- Cerebrovascular Surgery
Background:
- Cerebral aneurysms pose significant risks, necessitating effective surgical interventions.
- Traditional aneurysm surgery often requires extensive brain retraction.
- Minimally invasive approaches are being explored to reduce surgical morbidity.
Purpose of the Study:
- To evaluate the feasibility of using endoscopy for cerebral aneurysm visualization, dissection, and clipping.
- To assess the utility of the penscope in minimally invasive aneurysm surgery.
Main Methods:
- Utilizing endoscopic visualization for cerebral aneurysm surgery.
- Introducing endoscopes through small burr holes with minimal brain retraction.
- Employing the penscope, a specific endoscope requiring a 1.0 x 1.5 cm opening.
- Performing aneurysm clipping and managing intraoperative ruptures using the penscope.
Main Results:
- Endoscopic visualization, dissection, and clipping of cerebral aneurysms are achievable with current technology.
- Endoscopes, including the penscope, require minimal to no brain retraction.
- The penscope's larger working channel allows for the introduction of additional instruments (e.g., suction, clips) for managing complications like rupture.
Conclusions:
- Current endoscopic technology enables complete cerebral aneurysm clipping with minimal brain retraction.
- The penscope is particularly well-suited for aneurysm surgery due to its capacity to accommodate instruments for managing intraoperative ruptures.
