Relation between Site of Occlusion and Outcome of Intravenous Thrombolysis in a Cohort of Patients Studied with CT Angiography C. Barbara, A. Stafa, G. Procaccianti, L. Simonetti, M. Leonardi
From the beginning… Few slides about our “modus operandi” in acute stroke.
Intra-hospital Step When a patient is considered to be eligible for the trombolitic treatment, the dedicated “trombolysis team” will be alerted with “Stroke Yellow Code”
The principal inclusion criteria for the trombolysis: Both sex patients, age range 18-80 years Ischemic stroke generating an acute neurological deficit Starting symptoms: < 3 hours Brain CT excluding intracranial haemorrhage ASPECT Score: > 7
When we perform CTA of supra-aortic vessels & intracranial circulation? Always, if the patient is eligible for IV or IA trombolysis
TROMBOLYSIS: april 2008-september 2010
- 240 pts (ab 50%) excluded during ER evaluation, before CT scan starting symptoms: >3h before, or time not definable (stroke presumably in asleep patient): 54 Age > 80 5 mild neurological deficit 51 TIA 46 deep coma 23 dismetabolic coexisting diseas 20 epileptic seizures 18 psychiatrical clinical back-ground 8 other 15
- 95 pts (20%) excluded after CT-CTA scan intracranial hemorrhage 67 extracranial ICA occlusion 15 ASPECT score < 8 13 10 pts (their relatives) refused therapy
Overall Results Δ NIHSS 24 h: 5.0
T-shaped occlusion (15 pts) Δ NIHSS 24 h : -2
BM, 33 aa Left Hemiparesis
M1 occlusion (31 pts) Δ NIHSS 24 h: 3.9
“Mild” M1 occlusion
CR, F 58 aa Left hemiplegia 190’ aftert presuming start od symptoms CR, F 58 aa Left hemiplegia 190’ aftert presuming start od symptoms. IV rTPA
“Severe” M1 occlusion
BMP, 59 aa right hemiplegia 3h 20’ after presuming start of symptoms
Δ NIHSS 24 h: 9
M2 occlusion (39 pts) Δ NIHSS 24 h: 6.2
TL, 68 aa Left hemiplegia 3h 40’after presuming start of symptoms, IV rTPA
Distal branch occlusion (53 pts) Δ NIHSS 24 h: 6.5
TM, 62 aa Right hemiparesis and afasia
Admission brain CT
Admission CTA
36 h CT
TROMBOLYSIS H. Maggiore April 2008 – september 2010 Overall Outcome on 138 pts: Rankin Scale % 32 1-2 26 3 5 4-5 33 6 4 TOTAL 100
On the base of these CTA data In accord (+/-) with our neurologists
Three protocols that our Ethical Committee approved on July 2010 Pts with “mild” M1 occlusion: Synthesis Expansion randomization Pts with M2 or distal occlusion: IV, eventually ”bridging therapy” Pts with “T shaped” occlusion or “severe” occlusion in M1: “Opus” experimental study (intra-arterial thrombolysis by UV laser)
Some conclusive considerations The role of the diagnostical and therapeutical neuroradiology is fully recognized and formalized The intra-venous trombolysis? It works. The CT-Angio, performed in every case as a standard step of the protocol, represents an important tool for the definition of the prognosis and, potentially, for the definition of the therapeutical choice.
Thank you for the kind attention
