  1. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH (Grade IV and V) Prof . Dr. Leónidas M. Quintana Department of Neurosurgery – School of Medicine Valparaíso University - Chile

  2. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH Treated Ruptured Cerebral Aneurysms (%) 1990-2009 Total: 929 cases

  3. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH IV V

  4. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH CT Scan at admission......It makes the difference between the posterior management ( explained in the next slide) and prognosis 1 2 Pattern 1- Critical brain damage 2- Brain swelling and/or edema 3- Acute Hydrocephalus 4- Intracerebral Hematoma 3 4

  5. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH • Initial Medical Treatment • 1-ABC *Control blood gases- If GCS< 8 : Intubation • *Controlled ventilation- avoid hypoxemia • *CPP Management avoid hypotension (unclipped 120-150mmHg. • Systolic blood pressure) ;adecuate Central Venous Pressure (6-12 cm H2O) • 2-Sedation – Analgesics- if intubated = muscle relaxants • 3-Nimodipine 60mg q.4 hrs per NGT • 4-Phenytoin 1gr initial ; 100 mg q.8hrs per NGT • If GCS < 8: ICP Monitoring ; EVD or Spiegelberg system • HSS • ICP monitoring 2 Manitol • Comfort measuresHyperventilation • Surgery • 3 EVD 4 “as soon as possible”

  6. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH TOTAL : 214 CASES IN POOR SAH GRADE After the anterior management ( slide 5)- Re-evaluation at 12-24 hours No improvement : 75 cases Clinical improvement : 139 cases (35%) ( 65%) Comfort measures Angiography DIED DIRECT SURGERY

  7. TOTAL : 214 CASES IN POOR SAH GRADE IMPROVED 139 patients Grade IV 114 patients ( 82%) Grade V 25 patients ( 18%) NOT IMPROVED 75 patients(*) Grade IV 16 patients ( 21 %) Grade V 59 patients ( 79 %) (*)The majority of these patients had pattern 1 and 2 at the initial CT Scan Management of Ruptured Cerebral Aneurysms with Poor Grade SAH

  8. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH TIMING OF DIRECT OPERATION 139 PATIENTS WITH CLIPPED ANEURYSMS Before 48 hours 68 patients ( 49%) Between 48-72 hours 49 patients (35%) After 72 hours 22 patients (16%)

  9. TIMING OF SURGERY Left ICA- Ant choroidal An <24 hours Op. 96 hours Op. Right MCA An Compare brain edema……….. no or slight……………………..mild to severe parenchymal fragility no……………………………..yes blood-hardness of clots easy to aspirate……..………….difficult to aspirate

  10. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH 6 months follow up of 139 clipped aneurysms cases FUNCTIONAL STATE State I : return to normal life State II: return to life with mild limitations State III: return to life with severe limitations or vegetative state State IV: dead 114 patients Grade IV Global results State I 41 patients ( 36%) State II 24 patients ( 21%) Good 57% State III 17 patients ( 15%) State IV 32 patients ( 28%) Bad 43% 25 patients Grade V State I 6 patients ( 24 % ) State II 4 patients ( 16 % ) Good 40 % State III 7 patients ( 28 % ) State IV 8 patients ( 32 % ) Bad 60 % Total Mortality of Poor Grade SAH (n= 214 cases) 53,7%

  11. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH • Some considerations......... • This paper shows that early and aggresive management , medical & surgical treatment, is better than late management, in poor grade SAH ( 53,7 vs. 90 % mortality) • Early management courses until 48 hours after initial bleeding. • After that period is late management. • Not all grade IV&V patients have the same “damage pattern” • “Not all cases fall in the same bag”, as you can see in these images..... Critical brain damageBrain swellingAcute HydrocephalusIntracerebral Hematoma and/or edema

  12. Management of Ruptured Cerebral Aneurysms- SAH Grade IV and V Some considerations , that can aid to improve complications......... MCA aneurysm –short M1 bifurcation- Topical action of Nimodipine Vasospasm Pre topical application Post topical application

  13. Management of Ruptured Cerebral Aneurysms with Poor Grade SAH Some considerations , that can aid to improve complications......... Vasospasm Marked reduction of cerebral vasospasm with lumbar drainage of cerebrospinal fluid after subarachnoid hemorrhage Paul Klimo Jr, John R. W. Kestle, Joel D. Mac Donald, Richard H. Schmidt. Department of Neurosurgery, University of Utah, Salt Lake City, Utah (J Neurosurg 100:215–224, 2004) WE APPLY THE SAME CONCEPT WITH ON LAY SUBARACHNOID DRAINAGE “The V ventricle”

  14. Aneurysmal Subarachnoid Hemorrhage Management of Complications Hydrocephalus 1-Acute Hydrocephalus ( Obstructive ) , should be treated with External Ventricular Drainage, in cases of progressive neurological deterioration.We should avoid complications as rebleeding and infections (dripping reservoir over 20mmHg from 0 point) 2-Chronic Hydrocephalus (Communicating), should be prevented with Fenestration of LaminaTerminalis, to decrease the shunting rate,the incidence of vasospasm and to have a better clinical outcome . If it fails….. VP shunt Pre Op. 6hrs Post Op. FENESTRATION OF THE LAMINA TERMINALIS AS A VALUABLE ADJUNCT IN ANEURYSM SURGERY Norberto Andaluz, Mario Zuccarello The Neuroscience Institute,Department of Neurosurgery,University of Cincinnati College of Medicine (Neurosurgery 55:1050-1059, 2004)
