# Subarachnoid hemorrhage complicated by cerebral venous sinus thrombosis: a quantitative systematic review of cases

## TL;DR

This paper reviews cases where subarachnoid hemorrhage complicates cerebral venous sinus thrombosis, identifying potential predictors to aid diagnosis and treatment.

## Contribution

The study systematically identifies potential predictors for CVST complicated by SAH, offering insights for future research.

## Key findings

- Epilepsy, pregnancy history, and migraine history are potential predictors of CVST complicated by SAH.
- Thrombosis in the superior sagittal and transverse sinuses is associated with SAH in CVST cases.

## Abstract

Subarachnoid hemorrhage (SAH) is increasingly being recognized as a potential complication of cerebral venous sinus thrombosis (CVST), posing challenges in diagnosis and prognosis. We conducted a systematic search of case reports published from 1996 to 2023 in PubMed and Web of Science using the terms “sinus thrombosis, intracranial” and “subarachnoid hemorrhage” and identified 94 cases from 58 articles. Analysis of these cases suggests potential predictors of CVST complicated by SAH, including epilepsy, pregnancy history, abortion history, migraine history, thrombosis in the superior sagittal sinus, and thrombosis involving both the superior sagittal and transverse sinuses. These findings could stimulate further research on the diagnosis and treatment of CVST complicated by SAH.
