Abstract

Evidence is growing to support minimally invasive surgical evacuation of intraparenchymal hematomas, particularly those with minimal residual hematoma volumes following evacuation. To maximize the potential for neurologic recovery, it is imperative that the trajectory for access to the hematoma minimizes disruption of normal parenchyma. Flat panel detector CT-based navigation and needle guidance software provides a platform that uses flat panel detector CT imaging obtained on the angiography table to aid reliable and safe access to the hematoma. In addition to providing a high degree of accuracy, this method also allows convenient and rapid re-imaging to assess navigation accuracy and the degree of hematoma evacuation prior to procedural completion. We provide a practical review of the syngo iGuide needle guidance software and the methodology for incorporating its use, and the software of other vendors, in a variety of minimally invasive methods for evacuation of intraparenchymal hematomas.

Abstract

Objectives: Congenital vascular lesions commonly present in the head and neck, and most are managed conservatively. Location and rapid growth, however, may necessitate surgical intervention. Endoscopic endonasal surgery (EES) in the pediatric population has emerged as a viable option in treating sinonasal and skull base lesions. Utilizing these techniques in newborns carries unique challenges. The objective of this report is to describe the successful use of direct intralesional embolization followed by endoscopic endonasal resection of a venous malformation in a postnatal patient. Methods: We reviewed the case reported and reviewed the pertinent literature. Results: A 6-week-old infant was found to have a large right-sided sinonasal lesion confirmed as a venous malformation. Rapid growth, impending orbital compromise, and potential long-term craniofacial abnormalities demanded the need for urgent surgical intervention. Risk of bleeding was mitigated with direct intralesional embolization. Immediately afterward, the patient underwent endoscopic endonasal resection of the lesion. EES in the very young presents multiple challenges both anatomically and behaviorally. A multidisciplinary approach lead to a successful outcome. Conclusion: We report a case of a 6-week-old infant, the youngest reported patient to the authors' knowledge, who successfully underwent direct intralesional embolization followed by endoscopic endonasal resection of a sinonasal vascular malformation. This report highlights the challenges of this technique in the very young and demonstrates it as a viable treatment strategy for sinonasal vascular anomalies in this population.

20. Flat-panel dual-energy head computed tomography in the angiography suite after thrombectomy for acute stroke: A clinical feasibility study

Abstract

Background Management of large vessel occlusion (LVO) patients after thrombectomy is affected by the presence of intracranial hemorrhage (ICH) on post-procedure imaging. Differentiating contrast staining from hemorrhage on post-procedural imaging has been facilitated by dual-energy computed tomography (DECT), traditionally performed in dedicated computed tomography (CT) scanners with subsequent delays in treatment. We employed a novel method of DECT using the Siemens cone beam CT (DE-CBCT) in the angiography suite to evaluate for post-procedure ICH and contrast extravasation.Methods After endovascular treatment for LVO was performed and before the patient was removed from the operating table, DE-CBCT was performed using the Siemens Q-biplane system, with two separate 20-second CBCT scans at two energy levels: 70 keV (standard) and 125 keV with tin filtration (nonstandard). Post-procedurally, patients also underwent a standard DECT using Siemens SOMATOM Force CT scanner. Two independent reviewers blindly evaluated the DE-CBCT and DECT for hemorrhage and contrast extravasation.Results We successfully performed intra-procedural DE-CBCT in 10 subjects with no technical failure. The images were high-quality and subjectively useful to differentiate contrast from hemorrhage. The one hemorrhage seen on standard DECT was very small and clinically silent. The interrater reliability was 100% for both contrast and hemorrhage detection.Conclusion We demonstrate that intra-procedural DE-CBCT after thrombectomy is feasible and provides clinically meaningful images. There was close agreement between findings on DE-CBCT and standard DECT. Our findings suggest that DE-CBCT could be used in the future to improve stroke thrombectomy patient workflow and to more efficiently guide the postoperative management of these patients.
