Case report: Intra-procedural aneurysm rupture during endovascular treatment causing immediate, transient angiographic vasospasm.

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
introductionCerebral vasospasm is a major cause of delayed ischemic cerebral injury, typically occurring 3-14 days after subarachnoid hemorrhage (SAH). Ultra-early vasospasm is defined as angiographic vasospasm observed within 48 h of SAH onset. Immediate vasospasm at the time of aneurysmal rupture has been suspected, but has not been previously reported. We describe a case of immediate, transient vasospasm following intra-procedural aneurysmal rupture.
methodsA 55-year-old woman presented with SAH from a ruptured anterior communicating artery aneurysm. Subsequent coil embolization was complicated by an intra-procedural rupture following placement of the initial coil. A follow-up angiogram obtained after 9 min demonstrated moderate-to-severe vasospasm in the A2 segments of both anterior cerebral arteries.
resultsA repeat angiogram 20 min later demonstrated complete resolution of the vasospasm. The aneurysm was successfully obliterated with coil embolization. Post-procedure, the patient manifested no clinical vasospasm and made a good neurological recovery.
conclusionWe document a case of ultra-early cerebral vasospasm that occurred immediately after an intra-procedural aneurysmal rupture. Catheter-induced vasospasm from mechanical manipulation of extracranial vasculature is well described. However, immediate vasospasm related to extravascular blood has never before been reported. This finding suggests that extravascular blood can have a local direct effect (presumably mechanical) on cerebral blood vessels, and may be an important mechanism for vasospasm.
