Posterior Communicating Artery Compromise in Coil Embolization of Posterior Communicating Artery Aneurysms.
Article in Clinical neuroradiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
purposeWhether the posterior communicating artery (PcomA) can be safely compromised during endovascular treatment of a PcomA aneurysm is a matter of debate. Here we present clinical and radiologic outcomes, given this scenario.
methodsFrom data prospectively accrued between January 2004 and December 2012, records of 44 patients harboring 46 PcomA aneurysms were retrieved. All had suffered PcomA compromise in the course of endovascular coil embolization. Patients/aneurysms were stratified into those with complete (Group A) and incomplete (Group B) compromise depending on the degree of PcomA flow limitation documented by postembolization ipsilateral internal carotid artery angiography. Clinical and radiologic outcomes were accordingly assessed.
resultsAll affected vessels were hypoplastic PcomA variants (PcomA/P1 ratio, ≤ 1.0), with exception of a single dominant PcomA (PcomA/P1 ratio, 1.1). In Group A (23 patients, 23 aneurysms), no PcomA compromise-related infarction was evident, whereas in Group B (21 patients, 23 aneurysms), two ischemic events occurred. One patient suffered thalamic infarction, although patency of the PcomA was adequate in a follow-up angiogram, and another experienced a transient ischemic attack.
conclusionOur findings suggest that obstructed flow in hypoplastic PcomA variants during coil embolization of PcomA aneurysms carries no major consequence. However, incomplete compromise of the PcomA may be a source of delayed thromboembolic infarction.
