Transradial catheterization for prone neurosurgical treatment in a hybrid operating room: Technical considerations.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Surgical management of cerebrovascular diseases in a hybrid operating room (HOR) is advantageous in patients requiring postoperative cerebral angiography to confirm complete obliteration or in procedures requiring a combined open and endovascular approach. However, in the prone position, conventional transfemoral arterial access is challenging, as the introducer sheath is positioned between the patient and the surgical table, impeding catheter maneuverability. This case series outlines the technical details and potential advantages of the transradial approach in patients undergoing cerebrovascular surgery in the prone position. Case Description: Case 1 - A 55-year-old man was admitted with a subarachnoid hemorrhage. Cerebral angiography revealed a ruptured fusiform aneurysm at the origin of the left posterior inferior cerebellar artery (PICA). A hybrid surgical strategy consisting of an occipital artery-PICA bypass followed by endovascular internal trapping of the aneurysm was planned. Because the left radial artery puncture site was located on the dorsal surface near the operator with the patient in the prone position, catheter manipulation was more straightforward than with the conventional transfemoral approach. The procedure was completed without complications, except a cerebral infarction related to internal trapping. Case 2 - A 78-year-old man presented with a subarachnoid hemorrhage and was subsequently diagnosed with a craniocervical junction arteriovenous fistula. The draining vein was ligated with the patient in the prone position. Intraoperative cerebral angiography through the left radial artery confirmed complete shunt occlusion. Conclusion: The transradial approach is technically advantageous in prone-position procedures in the HOR; it facilitates catheter manipulation during complex cerebrovascular surgeries.
