Blood pressure status and recurrence risk after endovascular treatment of intracranial aneurysms: a systematic review and meta-analysis with narrative synthesis of blood pressure targets and hemodynamic evidence.

What was studied

This review looked at high blood pressure and return of brain aneurysms after endovascular care. It pooled cohort studies of recurrence by hypertension status. Other studies were summed up apart. These looked at achieved blood pressure, variability and fluid-flow models. 31 studies were included. 2,442 observations were pooled.

What they found

Hypertension showed a higher link with recurrence. The link was not significant. The odds ratio was 1.36. The range was 0.92 to 2.00. No recurrence study reported results by achieved blood pressure target. Variability studies were not pooled.

What it means for patients

The team says the data cannot yet name hypertension as an independent predictor. They say they are not enough to set a blood pressure goal to prevent it.

Why it is not certain yet

The direct data mostly concern a history of hypertension. Data on achieved blood pressure are indirect. Data on its variability are indirect too. The hypertension result was not statistically significant. This text uses the abstract and nothing else. Not every fact is in the abstract. Some of the work is not described there.
