• Dilemma: “can early surgery for poor grade patients be undertaken to reduce the risk of rebleeding without causing a significant deterioration in overall management outcome by inflicting excess morbidity and mortality?”

Summary of papers
• National Health and Medical Research Council (NHMRC) Evidence Hierarchy
- All articles Level III
(no randomised controlled trials or review)
- No randomized study for poor grade SAH
![Page 30: Ebs sah 2012](https://reader035.vdocuments.us/reader035/viewer/2022081504/55498a53b4c90583678b504f/html5/thumbnails/30.jpg)
EBS presentation 30
- Observational retrospective case series
- HH IV and V before and after EVD- All patients except those who showed CT scan evidence of destruction of critical areas had EVD- 97 surgery, 26 endovascular, <24h- Mortality 30% for treatment (100% for no surgery)- Outcome 1y: 47% good outcome after treatment
![Page 31: Ebs sah 2012](https://reader035.vdocuments.us/reader035/viewer/2022081504/55498a53b4c90583678b504f/html5/thumbnails/31.jpg)
EBS presentation 31
- Cohort study- HH IV-V- 35 Pt surgery
![Page 32: Ebs sah 2012](https://reader035.vdocuments.us/reader035/viewer/2022081504/55498a53b4c90583678b504f/html5/thumbnails/32.jpg)
EBS presentation 32
- Cohort study- All neurological grade included (except brain dead), with 45% (177) WFNS IV and V- Rebleeding higher in the first 24h ultra-early surgery (<24h)- DVE only if acute hydrocephalus on CT- 133 Pt with poor grade went ultra-early surgery- 3-12m follow-up
- good outcome 40%, mortality 45% for poor grade- rebleeding not an argument against early surgery (mean 12%, 20% rebleed for WFNS IV and V), only 11% have poor outcome- no debate between surgery and endovascular ttt

EBS presentation 33
• Early surgery for HH I-III:– 90% good neurological recovery range– Mortality 1.7-8%
![Page 34: Ebs sah 2012](https://reader035.vdocuments.us/reader035/viewer/2022081504/55498a53b4c90583678b504f/html5/thumbnails/34.jpg)
EBS presentation 34
• Rebleeding maximal in the first 24 h (4%)
• Second haemorrhage increases mortality to approximately 70%

Conclusions
No randomised studies for early vs delayed surgery
sound evidence on the best timing of surgery regarding mortality and morbidity is still lacking
![Page 36: Ebs sah 2012](https://reader035.vdocuments.us/reader035/viewer/2022081504/55498a53b4c90583678b504f/html5/thumbnails/36.jpg)
EBS presentation 36
Indirect comparison between different cohorts of patients suggests that early surgery improves outcome ( mortality > morbidity) after aneurysmal SAH in patient with poor clinical conditions at admission compared to delayed surgery.
Each patient must be individually assessedIntracerebral blood clot?Surgical challange in hostile conditions?Endovascular treatment?General medical conditions?Neurological and radiological deep brain lesions?Age?……
