Long-Term Stability of Patients Undergoing Endovascular Parent Artery Occlusion of Their Intracranial Artery.

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: Although endovascular parent artery occlusion (PAO) of the intracranial artery is a well-established treatment option, the long-term stability of cerebral blood flow remains a concern. This study aimed to evaluate the long-term clinical and radiological outcomes of patients who underwent PAO. Methods: The patients who underwent endovascular PAO of their internal carotid or vertebral artery (VA) between April 2011 and March 2022 were included in this observational study. Information about patient characteristics, details of the endovascular treatment, and clinical and radiological follow-up were collected. Results: The study included a total of 104 cases (average age, 52.9±12.6 years old; men, 73 [70.2%] cases; 95 [91.3%] VA PAO cases) from 8 centers. Most cases were performed in an emergency condition, such as ruptured VA dissecting aneurysm (73 cases [70.2%]). PAO was successful in all cases. Early stroke (within 30 days) occurred in 33 (31.7%) cases (31 cases in VA PAO and 2 cases in internal carotid PAO) with ischemic stroke (29 cases) comprising the largest group. Clinical follow-up over 1 month was available in 85 cases. During an average follow-up period of 45.8±25.8 months, 1 case of VA PAO experienced a stroke without functional deterioration. Imaging follow-up was performed in 75 cases. Recanalization of the occluded VA was observed in 2 cases. The remaining image change was contralateral VA stenosis after VA PAO. The incidence of clinical and radiological events was 1.2% and 1.1% per patient-year, respectively. Conclusion: Once the patients surpass the acute phase after PAO, their mid- to long-term course was stable. The risk of late stroke or de novo aneurysm formation was lower than expected in the literature, and the direct comparison to novel reconstructive techniques is warranted in future studies.
