Basilar Artery Dolichoectasia With Multiple Vessel Compression ("Vessel Sandwich") in Trigeminal Neuralgia: A Case Report and Literature Review.
Article in Neurosurgery practice, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 and importanceBasilar artery (BA) dolichoectasia is a rare vascular anomaly characterized by elongation, dilatation, and tortuosity of the BA. A dolichoectatic BA can cause neurovascular compression of the trigeminal nerve, resulting in classical trigeminal neuralgia (TN). Diagnosis and surgical management are often challenging due to the complex anatomy and the frequent presence of multiple neurovascular conflicts. CLINICAL PRESENTATION: We report the case of a 70-year-old man with multiple comorbidities and an 8-year history of right-sided TN refractory to pharmacological and interventional treatments. High-resolution brain MRI revealed BA dolichoectasia compressing the trigeminal nerve, with no additional neurovascular conflicts identified. Intraoperatively, multiple offending vessels were identified compressing the trigeminal nerve (BA, superior cerebellar artery, superior petrosal vein, and anterior inferior cerebellar artery). The patient underwent a successful 360° microvascular decompression, achieving complete decompression of all neurovascular conflicts. Postoperative recovery was uneventful, and the patient experienced immediate and sustained pain relief without complications.
conclusionTN caused by BA dolichoectasia with multiple neurovascular conflicts represents a complex diagnostic and surgical challenge. However, meticulous intraoperative exploration and complete decompression can result in rapid and long-lasting symptom resolution. This case underscores the importance of comprehensive preoperative imaging and individualized surgical planning.
