Amended Intraoperative Neuronavigation: Three-Dimensional Vascular Roadmapping with Selective Rotational Digital Subtraction Angiography.

Background: Accuracy of intraoperative cerebrovascular neuronavigation is difficult to maintain because of the ongoing need for brain shift correction. By including 3-dimensional rotational intraoperative digital subtraction angiography (3D-iDSA), the intraoperative cerebrovascular neuronavigation can be updated and upgraded throughout the microneurosurgical procedure. The aim of this technical note is to demonstrate the feasibility and advantage of updating and upgrading the accuracy of targeted cerebrovascular neuronavigation with an intraoperative 3D-DSA dataset.

Comparison of Intra- and Postoperative 3-Dimensional Digital Subtraction Angiography in Evaluation of the Surgical Result After Intracranial Aneurysm Treatment.

Background: Postoperative three-dimensional digital subtraction angiography (3D-DSA) is the gold standard in evaluating intracranial aneurysm (IA) remnants after clipping. Should intraoperative 3D-DSA image quality be equally good as postoperative 3D-DSA, it could supplant the latter as standard of care for follow-up of clipped IA.

Objective: To directly compare the quality of assessment of clipped IA by intraoperative and postoperative 3D-DSA.

Comparison of 3D intraoperative digital subtraction angiography and intraoperative indocyanine green video angiography during intracranial aneurysm surgery.

Objective: During the last decade, improvements in real-time, high-resolution imaging of surgically exposed cerebral vasculature have been realized with the successful introduction of intraoperative indocyanine green video angiography (ICGVA) and technical advances in intraoperative digital subtraction angiography (DSA). With the availability of 3D intraoperative DSA (3D-iDSA) in hybrid operating rooms, the present study offers a contemporary comparison for rates of accuracy and discordance.

Methods: In this retrospective study of prospectively collected data, 140 consecutive patients underwent microsurgical treatment of intracranial aneurysms (IAs) in a hybrid operating room.

Combined Endovascular and Microsurgical Treatment of Arteriovenous Malformations in the Hybrid Operating Room.

Background: Radical treatment of brain arteriovenous malformations (AVMs) remains a challenge despite recent advances in endovascular, microsurgical, and stereotactic radiosurgery treatments. The radical removal of AVMs with prevention of hemorrhage can be achieved through either single or combined modalities. Our retrospective study summarizes the safety and efficacy of combined endovascular embolization and microsurgical removal of AVMs in 49 consecutive patients in the hybrid operating room (hOR).
