Summary

Subarachnoid hemorrhage with negative angiography has a good prognosis in most patients. Repeating angiography is suggested for better diagnosis and management of these challenging cerebrovascular cases.

Area of Science:

  • Neurology
  • Neurosurgery
  • Vascular Neurology

Background:

  • Subarachnoid hemorrhage (SAH) accounts for approximately 10% of cerebrovascular diseases.
  • Ruptured cerebral aneurysms cause over 80% of SAH cases.
  • 5-16% of SAH patients present with negative angiography, posing diagnostic and therapeutic challenges.

Purpose of the Study:

  • To evaluate the diagnostic yield and clinical outcomes of repeat angiography in patients with SAH and initially negative findings.
  • To address the lack of consensus regarding repeat angiography protocols in cryptogenic SAH.

Main Methods:

  • Retrospective analysis of 14 patients diagnosed with SAH and negative initial angiography.
  • Patients underwent two or more repeat angiographic studies.
  • Clinical outcomes and prognosis were assessed.

Main Results:

  • The overall prognosis for patients with SAH and negative angiography was favorable, with 86% experiencing good outcomes.
  • The risk of re-hemorrhage after hospital discharge was found to be low.
  • Study findings were compared with existing literature on cryptogenic SAH.

Conclusions:

  • Repeat angiography may be beneficial in selected patients with SAH and negative initial studies.
  • Patients with SAH and negative angiography generally have a good prognosis.
  • Further research is needed to establish clear guidelines for repeat angiography in cryptogenic SAH.
