Abstract

fetched live from OpenAlex

Aneurysm disappearance and reappearance is a rare condition, typically described in isolated case reports. We present a case of rebleeding following coiling of a ruptured anterior communicating artery aneurysm. To our knowledge, this is the first documented case of rebleeding due to the development of a pseudoaneurysm arising on the opposite wall of a coiled anterior communicating aneurysm, in which microsurgical clipping, coiling and flow diversion were all applied. The pseudoaneurysm demonstrated recanalization 1 week after surgical clipping, necessitating endovascular coiling. Subsequently, a flow diverter was deployed 8 days after coiling, following early recanalization at the pseudoaneurysm base. At 10 months, the follow-up angiography confirmed complete exclusion of both the pseudoaneurysm and the opposite wall aneurysm. This case illustrates the aggressive course of cerebral pseudoaneurysms, drawing the attention to the diagnostic and therapeutic challenges they present.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
