IA consent formDisclaimerCatheter-based therapy for acute ischemic stroke is offered at many institutions based on local medical policies or investigational review board approval. Written informed consent should, in general, be obtained prior to treatment. The following written consent form is one example of this. In exceptional circumstances where patients are eligible for treatment but for who no appropriate caregiver can be contacted, local legal counsel should be consulted regarding policies for treatment.

The FUNC score is intended to provide guidance in clinical decision-making and patient selection for clinical trials. The components of FUNC score (age, GCS, ICH location, ICH volume, and pre-ICH cognitive impairment) are obtained on evaluation of patients with ICH upon arrival to the hospital. Based on the number of points assigned within each category (see FUNC Score Prediction Tool inset or dropdown menu) of the individual components, a total FUNC score is calculated (range 0-11). For each individual ICH patient, a particular FUNC score value corresponds to the % probability of attaining functional independence (Glasgow Outcome Score greater than or equal to 4) at 90 days (Entire Cohort).
To eliminate the effects of early withdrawal of care on outcome, we also calculated the likelihood of long-term functional recovery in those ICH patients who survived to 90 days (Survivors Only), and their % probabilities of achieving functional independence at 90 days are presented below, as well. In our study, no patient assigned a FUNC score less than or equal to 4 achieved functional independence at 90 days, while greater than 80% with a score of 11 did in both patient cohorts.
Y-axis: % ICH patients who reach functional independence at 90 days.
X-axis: FUNC score categories.
Data table: % functionally independent patients among the entire cohort and survivors only (per FUNC score category).

All FUNC score components are determined on admission, including ICH volume and location (determined on admission non-contrast head CT). Pre-ICH cognitive impairment is determined by family interview (IQCODE) or known history of dementia.

Catheter-based Clot Images
These sample images are from patients successfully treated with catheter-based Intra-arterial thrombolysis (IAT).
These blood clots were removed by a catheter. The catheter in this procedure, called Merci Retriever, is made by Concentric Medical. This catheter was given approval by the FDA in August 2005. This approval gave Concentric Medical authorization to develop its Merci Retriever structure, which helps do away with blood clots in patients' brains who are having an ischemic stroke.
