Background: Decompressive hemicraniectomy (DHC) reduces mortality and improves outcome after malignant middle cerebral artery (MCA) infarction but leaves a high number of survivors severely disabled. Attitudes among physicians toward the degree of disability that is considered acceptable and the impact of aphasia may play a major role in treatment decisions., Methods: DESTINY-S is a multicenter, international, cross-sectional survey among 1,860 physicians potentially involved in the treatment of malignant MCA infarction. Questions concerned the grade of disability, the hemisphere of the stroke, and the preferred treatment for malignant MCA infarction., Results: mRS scores of 3 or better were considered acceptable by the majority of respondents (79.3%). Only few considered a mRS score of 5 still acceptable (5.8%). A mRS score of 4 was considered acceptable by 38.0%. Involved hemisphere (dominant vs. non-dominant) was considered a major clinical symptom influencing treatment decisions in 47.7% of respondents, also reflected by significantly different rates for DHC as preferred treatment in dominant versus non-dominant hemispheric infarction (46.9 vs. 72.9%). Significant differences in acceptable disability and treatment decisions were found among geographic regions, medical specialties, and respondents with different work experiences., Conclusion: Little consensus exists among physicians regarding acceptable outcome and therapeutic management after malignant MCA infarction, and physician's recommendations do not correlate with available evidence. We advocate for a decision-making process that balances scientific evidence, patient preference, and clinical expertise.

Background: Decompressive hemicraniectomy reduces mortality after space-occupying MCA infarction. Data on the general public's opinion toward interventions that can save lives but leave the survivors impaired are lacking., Methods: In this population-based epidemiological study in a German city, we surveyed 312 adults in a telephone interview. Here, we presented a scenario of a space-occupying MCA infarct. We evaluated probands' attitude toward decompressive surgery in general, and toward outcome scenarios according to Rankin scale (RS) definitions., Results: 312 persons (157 women, 52 ± 20 years) were interviewed. 58 persons had difficulty comprehending the proposed scenario, most of them being of advanced age (79 ± 5 years). From the remaining 254 responders 5 (2%) persons favoured surgical intervention, 149 (58%) were undecided, and 100 (39%) were opposed to surgery. The number of individuals opting for surgery rose in scenarios with a better outcome: If very severe impairment was anticipated (RS 5), only 3 (1%) persons favored surgery. With severe (RS 4), moderate (RS3), and slight impairment (RS2) the numbers were at 16 (6%), 60 (24%), and 161 (63%), respectively. We found no association with age, sex, religion, education, self-estimated health status, or marital status., Conclusions: Explaining complex medical situations to laypersons poses a major problem, particularly to those of old age. Only a minority favors life-saving medical interventions if survival is associated with deficits of unpredictable degree. The majority of persons does not favor intervention even if only moderate impairment is anticipated. Decompressive surgery may in fact be against the values of many individuals.

Background: Decompressive surgery for malignant middle cerebral artery infarction increases the number of surviving patients; this, however, leaves some patients severely disabled. This study analyzed the patients' retrospective consent to hemicraniectomy in light of the experienced functional outcome 12 months after hospital stay., Methods: This retrospective study included all patients who underwent decompressive hemicraniectomy for malignant middle cerebral artery infarction in the Department of Neurology, University of Erlangen, Germany, from January 2006 until March 2009. Data on mortality and functional outcome (measured by the modified Rankin Scale; mRS) 6 and 12 months after treatment were correlated with retrospective consent to hemicraniectomy as well as with a quality of life instrument (EuroQol). Data were obtained by structured telephone interviews with the patients themselves or their closest relatives., Results: In the study period 28 patients received decompressive surgery. Retrospective consent to hemicraniectomy was 82.1%. Five patients, or their closest relatives, would not agree to hemicraniectomy again, given their functional outcome after 1 year. Two out of two patients who experienced an mRS of 5 would not have consented. Low quality of life was most often declared in this subgroup., Conclusions: Retrospective consent to hemicraniectomy for treatment of malignant MCA infarction depends on functional long-term outcome. We need to identify those patients who would survive the malignant MCA infarction due to decompressive surgery but only reach a severely reduced functional status.
