Incidence of surgical site infections after cervical spine surgery: results of a single-center cohort study adhering to multimodal preventive wound control protocol.

PURPOSE: The incidence of surgical site infections is considered a relevant indicator of perioperative and postoperative care quality. The aim of this study is to analyze and evaluate SSIs after elective cervical spine surgery under the guidance of our preventive multimodal wound protocol. METHODS: A monocentric observational cohort study analyzed 797 patients who underwent cervical spine surgery from 2005 to 2010 (mean age 51.58 ± 11.74 year, male 56.09%, mean BMI 26.87 ± 4.41, ASA score 1-2 in 81.68% of patients), fulfilling the entry criteria: (1) cervical spine surgery performed by neurosurgeons (degenerative disease 85.19%, trauma 11.04%, tumor 3.76%), (2) elective surgery, (3) postoperative care in our neurointensive care unit. Our preventive wound control protocol management focused mainly on antibiotic prophylaxis, wound hygiene regime, and drainage equipment. All wound complications and surgical site infections were monitored up for 1 year after surgery. RESULTS: We had only 2 (0.25%) patients with SSI after cervical spine surgery-one organ/space infection (osteomyelitis, primary due to liquorrhea) after anterior surgical approach, and one deep surgical site infection (due to dehiscence) after posterior approach. We had 17 (2.13%) patients with some wound complications (secretion 7, dehiscence 4, hematoma 1, edema 3, and liquorrhea 2) that were not classified as SSI according to the CDC guidelines. CONCLUSION: Concerning our study population of patients undergoing elective cervical surgery, with ASA scores 1-2 in 81.68% of our patients, the incidence of SSI was 0.14% after anterior surgical approach, 1.4% after posterior surgical approach, and 0.25% altogether in the referred cohort.

Trends and outcomes for non-elective neurosurgical procedures in Central Europe during the COVID-19 pandemic.

The world currently faces the novel severe acute respiratory syndrome coronavirus 2 pandemic. Little is known about the effects of a pandemic on non-elective neurosurgical practices, which have continued under modified conditions to reduce the spread of COVID-19. This knowledge might be critical for the ongoing second coronavirus wave and potential restrictions on health care. We aimed to determine the incidence and 30-day mortality rate of various non-elective neurosurgical procedures during the COVID-19 pandemic. A retrospective, multi-centre observational cohort study among neurosurgical centres within Austria, the Czech Republic, and Switzerland was performed. Incidence of neurosurgical emergencies and related 30-day mortality rates were determined for a period reflecting the peak pandemic of the first wave in all participating countries (i.e. March 16th-April 15th, 2020), and compared to the same period in prior years (2017, 2018, and 2019). A total of 4,752 emergency neurosurgical cases were reviewed over a 4-year period. In 2020, during the COVID-19 pandemic, there was a general decline in the incidence of non-elective neurosurgical cases, which was driven by a reduced number of traumatic brain injuries, spine conditions, and chronic subdural hematomas. Thirty-day mortality did not significantly increase overall or for any of the conditions examined during the peak of the pandemic. The neurosurgical community in these three European countries observed a decrease in the incidence of some neurosurgical emergencies with 30-day mortality rates comparable to previous years (2017-2019). Lower incidence of neurosurgical cases is likely related to restrictions placed on mobility within countries, but may also involve delayed patient presentation.

Surgery of acute occlusion of the extracranial internal carotid artery - a meta-analysis.

Acute occlusion of the extracranial internal carotid artery (eICA) is associated with poor prognosis. Surgical desobliteration has not received adequate attention in recent years. We therefore conducted a literature review and meta-analysis of surgical studies published after 2000 that treated eICA occlusion surgically in an emergency setting. The search identified 10 relevant articles that included a total of 175 patients. The outcomes analysed included rates of recanalization (93 %), early neurological improvement (66 %), modified Rankin Scale 0-2 (62 %), mortality (5 %), early reocclusion (4 %), in-hospital stroke (4 %) and symptomatic intracerebral haemorrhage (4 %). In conclusion, acute surgical desobliteration of eICA occlusion leads to high rates of recanalization and a majority of patients experience early neurological improvement and achieve favourable outcome. Rates of mortality, early reocclusion, in-hospital stroke and sICH are acceptable in the view of unfavourable natural history.

Potential brain dead organ donation in neurocritical care mortality.

BACKGROUND: Mortality is a marker of quality in neurocritical care, but it also provides potential for donors after brain death (DBD) following irreversible acute brain damage. The aim of this study was to analyze the neurointensive care unit (NICU) mortality rate and recovery of potential DBD. METHODS: We performed a 10-year prospective observational cohort computer database analysis of 6138 acute neurological and neurosurgical patients (pts, 58.2% male, mean: age 55.9±14.7 years, body weight 78.3±15.6 kg, body mass index 26.9±4.7, NICU stay 3.8±5.3 days): 3462 (56.4%) pts with brain disease (mostly stroke 43.2%, tumor 31.1%, trauma 13.6%); 10.3% pts with internal carotid artery (ICA) stenosis; 32.6% pts with spine diseases, and others. Mean Acute Physiology and Chronic Health Evaluation (APACHE) II score on admission was 10.63±5.2 and Glasgow Coma Scale on admission was 13.79±2.51. RESULTS: There were 159 (2.6%) cases of mortality with a significantly higher mortality rate in pts with brain diseases (95.6% of deceased pts, P<0.001) than in ICA stenosis (0.6%), spine (1.9%) and from others (1.9%). There were 23 (14.5%) pts with clinical signs of brain death, of whom 13 (56.5%) became donors. The main reasons for non-recovery of potential donors were hemodynamic instability (16.7%) and family reluctance (12.5%). CONCLUSIONS: The study showed that our NICU mortality was 2.6%. There were relatively few clinical signs of brain death and not all potential donors were recovered.

Fatal intracranial aneurysm rupture after thrombolytic treatment for ischemic stroke: a case report and literature review.

Intravenous thrombolysis is a proven treatment of acute ischemic stroke. Its complications include intracranial hemorrhage; the risk may be increased in the presence of an unruptured aneurysm. We present a case report of a patient who suffered fatal subarachnoid hemorrhage after thrombolysis from a known aneurysm. A history of recent previously inexperienced headaches was revealed retrospectively, suggestive of sentinel bleedings. A similar patient was identified in the literature; we thus propose that this history should be excluded in patients harboring an aneurysm considered for thrombolytic treatment.

Low incidence of multidrug-resistant bacteria and nosocomial infection due to a preventive multimodal nosocomial infection control: a 10-year single centre prospective cohort study in neurocritical care.

BACKGROUND: Nosocomial infection (NI) control is an important issue in neurocritical care due to secondary brain damage and the increased morbidity and mortality of primary acute neurocritical care patients. The primary aim of this study was to determine incidence of nosocomial infections and multidrug-resistant bacteria and seek predictors of nosocomial infections in a preventive multimodal nosocomial infection protocol in the neurointensive care unit (NICU). The secondary aim focused on their impact on stay, mortality and cost in the NICU. METHODS: A10-year, single-centre prospective observational cohort study was conducted on 3464 acute brain disease patients. There were 198 (5.7%) patients with nosocomial infection (wound 2.1%, respiratory 1.8%, urinary 1.0%, bloodstream 0.7% and other 0.1%); 67 (1.9%) with Extended spectrum beta-lactamase (ESBL); 52 (1.5%) with Methicillin-resistant Staphylococcus aureus (MRSA), nobody with Vancomycin-resistant enterococcus (VRE). The protocol included hygienic, epidemiological status and antibiotic policy. Univariate and multivarite logistic regression analysis was used for identifying predictors of nosocomial infection. RESULTS: From 198 NI patients, 153 had onset of NI during their NICU stay (4.4%; wound 1.0%, respiratory 1.7%, urinary 0.9%, bloodstream 0.6%, other 0.1%); ESBL in 31 (0.9%) patients, MRSA in 30 (0.9%) patients. Antibiotics in prophylaxis was given to 63.0% patients (59.2 % for operations), in therapy to 9.7% patients. Predictors of NI in multivariate logistic regression analysis were airways (OR 2.69, 95% CI 1.81-3.99, p<0.001), urine catheters (OR 2.77, 95% CI 1.00-7.70, p=0.050), NICU stay (OR 1.14, 95% CI 1.12-1.16, p<0.001), transfusions (OR 1.79, 95% CI 1.07-2.97, p=0.025) antibiotic prophylaxis (OR 0.50, 95% CI 0.34-0.74, p<0.001), wound complications (OR 2.30, 95% CI 1.33-3.97, p=0.003). NI patients had longer stay (p<0.001), higher mortality (p<0.001) and higher TISS sums (p<0.001) in the NICU. CONCLUSIONS: The presented preventive multimodal nosocomial infection control management was efficient; it gave low rates of nosocomial infections (4.2%) and multidrug-resistant bacteria (ESBL 0.9%, MRSA 0.9% and no VRE). Strong predictors for onset of nosocomial infection were accesses such as airways and urine catheters, NICU stay, antibiotic prophylaxis, wound complications and transfusion. This study confirmed nosocomial infection is associated with worse outcome, higher cost and longer NICU stay.

Simple size-controlled synthesis of Au nanoparticles and their size-dependent catalytic activity.

The controlled preparation of Au nanoparticles (NPs) in the size range of 6 to 22 nm is explored in this study. The Au NPs were prepared by the reduction of tetrachloroauric acid using maltose in the presence of nonionic surfactant Tween 80 at various concentrations to control the size of the resulting Au NPs. With increasing concentration of Tween 80 a decrease in the size of produced Au NPs was observed, along with a significant decrease in their size distribution. The size-dependent catalytic activity of the synthesized Au NPs was tested in the reduction of 4-nitrophenol with sodium borohydride, resulting in increasing catalytic activity with decreasing size of the prepared nanoparticles. Eley-Rideal catalytic mechanism emerges as the more probable, in contrary to the Langmuir-Hinshelwood mechanism reported for other noble metal nanocatalysts.

N-terminal pro-B-type Natriuretic Peptide in three different mechanisms of dysnatremia onset after a child's craniopharyngioma surgery.

Craniopharyngioma, due to its sellar location, can be perioperatively complicated by different types of dysnatremia. We present a rare postoperative onset of a combination of three different mechanisms of dysnatremia with N-terminal pro-B-type Natriuretic Peptide (NT-proBNP) and renal function parameters in a boy with a good outcome after craniopharyngioma surgery: 1/ Central diabetes insipidus (CDI) onset immediately after the operation, hypernatremia with peak serum sodium (SNa) 158 mmol/l) caused by free water polyuria (electrolyte-free water clearance, EWC 0.104 ml/s), NT-proBNP 350 pg/ml; 2/ cerebral salt wasting (CSW) onset on day 7, hyponatremia (SNa 128 mmol/l) with hypoosmolality (measured serum osmolality, SOsm 265 mmol/kg) caused by natriuresis (sodium - daily output 605 mmol/day, fractional excretion 0.035), NT-proBNP 191 pg/ml; 3/ Polydypsia onset on day 11 caused hyponatremia (SNa 132 mmol/l), EWC 0.015, NT-proBNP 68 pg/ml.

Five-Year Follow-Up on Transplanted Organs From Donors After Brain Death After Acute Stroke.

OBJECTIVES: Efficient intensive care donor management can help alleviate the shortage of organs for transplant. The aim of this study was to investigate the efficiency of management of donors after brain death from our neurointensive care unit. MATERIALS AND METHODS: We conducted a prospective observational 5-year follow-up on 29 transplanted organs from 14 brain-dead donors after acute stroke (7 subarachnoid and 4 intracerebral hemorrhages, 3 ischemic strokes). Mean age of donors was 56.2 ± 8.70 years, and mean number of days of artificial ventilation was 5.0 ± 3.84. We transplanted 27 kidneys and 2 livers to 29 patients with mean age of 55.3 ± 9.76 years. No hearts or lungs were transplanted from these donors. RESULTS: Of the 27 patients who underwent kidney transplant, 21 patients (78%) lived 5 years; of those, 17 patients (63%) had functional grafts. One patient (4%) had a primary afunctional graft, and 3 patients (11%) had graft rejection (at 3, 15, and 41 mo). Six patients (22%) died after kidney transplant, with 1 patient in this group having a functional graft, 1 patient having a primary afunctional graft, and 4 patients (15%) having graft rejection (at 1, 12, 44, and 56 mo). The 2 patients with liver transplants lived 5 years with functional grafts. CONCLUSIONS: The 5-year follow-up showed that organs from 14 brain-dead donors improved and saved 19 lives, with 17 patients receiving kidney transplants and 2 patients receiving liver transplants. Another 7 patients had only partially improved quality of life.

Causes of poor outcome in patients admitted with good-grade subarachnoid haemorrhage.

BACKGROUND: Surgical risk in patients with unruptured aneurysms is well known. The relative impact of surgery and natural history of subarachnoid haemorrhage (SAH) on patients in good clinical condition (World Federation of Neurological Surgeons [WFNS] grades 1 and 2) is less well quantified. The aim of this study was to determine causes of poor outcome in patients admitted in good grade SAH. METHODS: A retrospective study of prospectively collected data among WFNS-1 and -2 patients: demographics, SAH and aneurysm-related data, surgical complications and outcome as assesed by the Glasgow Outcome Scale (GOS). Causes of poor outcome (GOS 1-3) were determined. RESULTS: During a 7-year period (2009-15), 56 patients with SAH WFNS-1 (39 patients) or WFNS-2 (17 patients) were treated surgically (21 men, 35 women; mean age, 52.4 years). According to the Fisher scale, 19 patients were grade 1 or 2; 37 patients were grade 3 or 4. Most aneurysms were located at anterior communicating (26) or middle cerebral (15) artery. Altogether, 11 patients (19.6%) achieved GOS 1-3. This was attributed to SAH-related complications in six patients (rebleeding, vasospasm), surgery in four patients (postoperative ischaemia in two, haematoma and ventriculitis in one patient each), grand-mal seizure with aspiration in one patient. Age over 60 years (p = 0.017) and presence of hydrocephalus (p < 0.001) were statistically significant predictors of poor GOS; other variables (e.g. sex, Fisher grade, aneurysm size or location, use of temporary clips, intraoperative rupture, vasospasm) were not significant. CONCLUSIONS: Patients admitted in good-grade SAH achieve favourable outcome following surgical aneurysm repair in the majority of cases. Negative factors include age over 60 years and presence of hydrocephalus. Aneurysm surgery following good-grade SAH still carries a small but significant risk similar to that shown in large multi-institutional trials.

Dysnatremia as a poor prognostic indicator in patients with acute subarachnoid hemorrhage.

BACKGROUND: Dysnatremias are common and carry a risk of poor prognosis in acute subarachnoid hemorrhage (SAH) patients. The aim of this study was to determine the frequency and outcome of dysnatremias in 344 SAH patients treated by a targeted sodium management regimen. METHODS: We performed a 10-year observational dysnatremia study. Hyponatremia was defined as serum sodium (SNa) below 135 mmol/L, hypernatremia SNa above 150 mmol/L. RESULTS: Dysnatremia occurred in 35.8% patients; this was more frequently hyponatremia (19.8%) with a mean SNa 132.23±2.09 mmol/L, (16.0% mild, 3.2% moderate, 0.6% severe). Hypernatremia occurred less commonly in 11.9%, P<0.001 with a mean SNa 154.21±3.72 mmol/L, (6.1% mild, 2.9% moderate, 2.9% severe). In 4.8% of patients there were episodes of both dysnatremias. The incidence of hypo-osmolar hyponatremia was 6.4%, Cerebral salt wasting (CSW) 3.5%, syndrome of inappropriate secretion of antidiuretic hormone (SIADH) 0.3% and Central diabetes insipidus 1.7%. The hypernatremic patients had a higher inpatient mortality rate (P=0.001) and a worse overall outcome (P<0.001) than those hyponatremic or normotremic patients. Multivariate logistic regression showed that hypernatremia was an independent risk factor for increased inpatient mortality and poor outcome in patients with SAH. CONCLUSIONS: Our 10-year targeted sodium management regimen in acute SAH patients showed that dysnatremias were frequent, predominantly hyponatremia of which the more usual causes were CSW and not SIADH. Hypernatremia was shown to be an independent risk factor for inpatient mortality and poor outcome.

Four-year results of a prospective single-arm study on 200 semi-constrained total cervical disc prostheses: clinical and radiographic outcome.

OBJECTIVE Recent studies have described encouraging outcomes after cervical total disc replacement (cTDR), but there are also critical debates regarding the long-term effects of heterotopic ossification (HO) and the prevalence of adjacent-level degeneration. The aim in this paper was to provide 4-year clinical and radiographic outcome results on the activ C disc prosthesis. METHODS A total of 200 subjects underwent single-level activ C (Aesculap AG) implantation between C-3 and C-7 for the treatment of symptomatic degenerative disc disease. Clinical and radiographic assessments were performed preoperatively, intraoperatively, at discharge, and again at 6 weeks, 6 months, 1 year, 2 years, and 4 years. Radiographic evaluations were done by an independent core laboratory using a specific software for quantitative motion analysis. RESULTS Neck Disability Index (NDI) and visual analog scale (VAS) score for neck and arm pain decreased significantly from baseline to the 4-year follow-up. The mean improvement for NDI was 20, for VAS severity and frequency of neck pain 26.4 and 28, and for VAS severity and frequency of arm pain 30.7 and 35.1, respectively. The neurological situation improved for the majority of patients (86.4%); 76.1% of cases were asymptomatic. Subsequent surgical interventions were reported in 7% of the cases, including device removals in 3%. In 2.5% a subsidence greater than 3 mm was recorded; 1 of these cases also had a migration greater than 3 mm. No device displacement, expulsion, disassembly, loose or fractured device, osteolysis, or facet joint degeneration at the index level was observed. Segmental lordotic alignment changed from -2.4° preoperatively to -6.2° at 4 years, and postoperative height was maintained during the follow-up. Advanced HO (Grade III and IV) was present in 27.1% of the cases; 82.4% showed segmental mobility. A progression of radiographic adjacent-segment degeneration occurred in 28.2%, but only 4.5% required surgical treatment. CONCLUSIONS The activ C is a safe and effective device for cervical disc replacement confirming the encouraging results after cTDR. Clinical trial registration no.: NCT02492724 ( clinicaltrials.gov ).

Highly efficient silver particle layers on glass substrate synthesized by the sonochemical method for surface enhanced Raman spectroscopy purposes.

A fast method for preparing of silver particle layers on glass substrates with high application potential for using in surface enhanced Raman spectroscopy (SERS) is introduced. Silver particle layers deposited on glass cover slips were generated in one-step process by reduction of silver nitrate using several reducing agents (ethylene glycol, glycerol, maltose, lactose and glucose) under ultrasonic irradiation. This technique allows the formation of homogeneous layers of silver particles with sizes from 80nm up to several hundred nanometers depending on the nature of the used reducing agent. Additionally, the presented method is not susceptible to impurities on the substrate surface and it does not need any additives to capture or stabilize the silver particles on the glass surface. The characteristics of prepared silver layers on glass substrate by the above mentioned sonochemical approach was compared with chemically prepared ones. The prepared layers were tested as substrates for SERS using adenine as a model analyte. The factor of Raman signal enhancement reached up to 5·10(5). On the contrary, the chemically prepared silver layers does not exhibit almost any pronounced Raman signal enhancement. Presented sonochemical approach for preparation of silver particle layers is fast, simple, robust, and is better suited for reproducible fabrication functional SERS substrates than chemical one.

The intraoperative portable CT scanner-based spinal navigation: a viable option for instrumentation in the region of cervico-thoracic junction.

PURPOSE: Innovative intraoperative imaging modalities open new horizons to more precise image acquisition and possibly to better results of spinal navigation. Planning of screw entry points and trajectories in this prospective study had been based on intraoperative imaging obtained by a portable 32-slice CT scanner. The authors evaluated accuracy and safety of this novel approach in the initial series of 18 instrumented surgeries in anatomically complex segment of cervico-thoracic junction. METHODS: We report on the single-institution results of assessment of anatomical accuracy of C5-T3 pedicle screw insertion as well as its clinical safety. The evaluation of total radiation dose and of time demands was secondary endpoint of the study. RESULTS: Out of 129 pedicle screws inserted in the segment of C5-T3, only 5 screws (3.9 %) did not meet the criteria for correct implant positioning. These screw misplacements had not been complicated by neural, vascular or visceral injury and surgeon was not forced to change the position intraoperatively or during the postoperative period. Quality of intraoperative CT imaging sufficient for navigation was obtained at all spinal segments regardless of patient´s habitus, positioning or comorbidity. A higher radiation exposition of the patient and 27 min longer operative time are consequences of this technique. CONCLUSIONS: The intraoperative portable CT scanner-based spinal navigation is a reliable and safe method of pedicle screw insertion in cervico-thoracic junction.

Comparative study of antimicrobial activity of AgBr and Ag nanoparticles (NPs).

The diverse mechanism of antimicrobial activity of Ag and AgBr nanoparticles against gram-positive and gram-negative bacteria and also against several strains of candida was explored in this study. The AgBr nanoparticles (NPs) were prepared by simple precipitation of silver nitrate by potassium bromide in the presence of stabilizing polymers. The used polymers (PEG, PVP, PVA, and HEC) influence significantly the size of the prepared AgBr NPs dependently on the mode of interaction of polymer with Ag+ ions. Small NPs (diameter of about 60-70 nm) were formed in the presence of the polymer with low interaction as are PEG and HEC, the polymers which interact with Ag+ strongly produce nearly two times bigger NPs (120-130 nm). The prepared AgBr NPs were transformed to Ag NPs by the reduction using NaBH4. The sizes of the produced Ag NPs followed the same trends--the smallest NPs were produced in the presence of PEG and HEC polymers. Prepared AgBr and Ag NPs dispersions were tested for their biological activity. The obtained results of antimicrobial activity of AgBr and Ag NPs are discussed in terms of possible mechanism of the action of these NPs against tested microbial strains. The AgBr NPs are more effective against gram-negative bacteria and tested yeast strains while Ag NPs show the best antibacterial action against gram-positive bacteria strains.

Intraoperative portable CT-scanner based spinal navigation--a feasibility and safety study.

BACKGROUND: Navigation based on an intraoperative CT scan is not a new approach to spinal instrumentation. Innovative intraoperative imaging technology, however, opens new horizons to more precise image acquisition as well as to further workflow. Planning of screw entry-points and trajectories in this study had been based on intraoperative imaging obtained by a portable 32-slice CT scanner. This prospective study evaluates feasibility, accuracy, and safety of this novel approach in an initial series of 85 surgeries. METHOD: Medical records and radiological materials of 82 patients who underwent the first 85 consecutive stabilisations were analysed. Incorrect screw position, medical and technical complications as well as availability of this procedure in particular spinal levels were the subject of evaluation. RESULTS: Out of 571 implants inserted in all spinal levels, only five screws (0.87 %) did not meet the criteria for correct implant position. These screw misplacements had not been complicated by neural, vascular or visceral injury and the surgeon was not forced to change the position intraoperatively or during the postoperative period. The quality of intraoperative CT imaging sufficient for navigation was obtained at all spinal segments regardless of a patient's habitus or positioning or comorbidity. CONCLUSION: Intraoperative portable CT scanner-based navigation seems to be an effective way of doing spinal instrumentation guidance. High precision of implant insertion confirms the preconditions of navigation usage during more complex surgeries at any level of the spine.

Acute extracranial occlusion of the internal carotid artery: emergent surgery remains a viable option.

BACKGROUND: Acute symptomatic occlusion of extracranial internal carotid artery (eICA) can lead to a critical and potentially devastating stroke associated with high morbidity and mortality. Optimal treatment remains unclear. We analyzed our institutional experience with emergent surgical recanalization of acutely occluded eICA. METHODS: Retrospective analysis of hospital records, surgical reports, imaging studies and outpatient records. Final outcome was assessed according to modified Rankin Scale (mRS). RESULTS: Between January 2010 and September 2013, 22 patients underwent emergent surgical recanalization. There were 17 men and five women, mean age 65.4 years (range 37-85). Mean admission National Institute of Health Stroke Scale (NIHSS) was 12 (range 6-21). All patients had evidence of salvageable penumbra on perfusion computed tomography. Tandem intracranial lesion was present in nine patients. Surgical recanalization was successful in 16 patients (72.7 %). Twenty-four hours after surgery, 17 patients (77.2 %) improved by a minimum of 1 point on NIHSS, 14 patients (63.6 %) improved by three and more points; two patients deteriorated by two and five points, the latter treated initially with systemic thrombolysis due to intracranial hemorrhage. No other intracranial hematoma was observed. During 30 days following surgery, two patients died (9 % mortality rate) due to severity of initial stroke. On discharge, four patients were classified as mRS 0, five patients as mRS 1, five patients as mRS 2 and six patients as mRS 4. Favorable recovery (mRS 0-2) was achieved in 14 patients (63.6 %). No change in mRS was observed at three months. CONCLUSIONS: Our results suggest that emergent surgical desobliteration of occluded eICA can lead to favorable recovery in a majority of patients. Patient selection based on penumbra imaging is crucial. Given the popularity and simplicity of carotid endarterectomy, the procedure should by no means be abandoned in the treatment of acute eICA occlusion.
