<b><i>Background:</i></b> While endovascular stroke treatment (EST) of large vessel occlusions in acute ischemic stroke (AIS) is proven to be safe and effective, there are subgroups of patients with increased rates of hemorrhages. Our goal was to identify risk factors for intracerebral hemorrhage and to assess whether acute carotid artery stenting (CAS) was associated with increased bleeding rates. <b><i>Methods:</i></b> We performed a retrospective analysis of our monocentric prospective stroke registry in the period from May 2010 to May 2018 and compared AIS patients receiving EST with (<i>n</i> = 73) versus without acute CAS (<i>n</i> = 548). Patients with intracranial stents, intra-arterial thrombolysis, or dissection of the carotid artery were excluded. <b><i>Results:</i></b> Parenchymal hemorrhage rates (PH2 according to the ECASS classification) and symptomatic hemorrhage (sICH) rates were increased in EST patients receiving CAS with odds being 6.3 (PH2) and 6.5 (sICH) times higher (PH2 17.8 vs. 3.3%, <i>p</i> &#x3c; 0.001 and sICH: 16.4 vs. 2.9%, <i>p</i> &#x3c; 0.001). Additional systemic thrombolysis with rtPA (IVRTPA) was no risk factor for cerebral hemorrhage (<i>p</i> = 0.213). <b><i>Conclusion:</i></b> AIS patients receiving EST with acute CAS and consecutive tirofiban or dual antiplatelet therapy suffered from an increased risk of relevant secondary intracranial bleeding. After adjusting for confounders, tirofiban and dual antiplatelet therapy were associated with higher bleeding rates.

BackgroundWhile dual antiplatelet therapy (dAPT) is standard of care following carotid artery stenting (CAS), the optimal dAPT regimen and duration has not been established.MethodsWe canvassed a large national database (IBM MarketScan) to identify patients receiving carotid endarterectomy (CEA) or CAS for treatment of ischemic stroke or carotid artery stenosis from 2007 to 2016. We performed univariable and multivariable regression methods to evaluate the impact of covariates on post-CAS stroke-free survival, including post-discharge antiplatelet therapy.ResultsA total of 79 084 patients diagnosed with ischemic stroke or carotid stenosis received CEA (71 178; 90.0%) or CAS (7906; 10.0%). After adjusting for covariates, <180 days prescribed post-CAS P2Y12-inhibition was associated with increased risk for stroke (<90 prescribed days HR=1.421, 95% CI 1.038 to 1.946; 90–179 prescribed days HR=1.484, 95% CI 1.045 to 2.106). The incidence of hemorrhagic complications was higher during the period of prescribed P2Y12-inhibition (1.16% per person-month vs 0.49% per person-month after discontinuation, P<0.001). The rate of extracranial hemorrhage was nearly six-fold higher while on dAPT (6.50% per patient-month vs 1.16% per patient-month, P<0.001), and there was a trend towards higher rate of intracranial hemorrhage that did not reach statistical significance (5.09% per patient-month vs 3.69% per patient-month, P=0.0556). Later hemorrhagic events beyond 30 days post-CAS were significantly more likely to be extracranial (P=0.028).ConclusionsIncreased duration of post-CAS dAPT is associated with lower rates of readmissions for stroke, and with increased risk of hemorrhagic complications, particularly extracranial hemorrhage. The potential benefit of prolonging dAPT with regard to ischemic complications must be balanced with the corresponding increased risk of predominantly extracranial hemorrhagic complications.

We describe a patient with subcutaneous hematoma associated with manual cervical massage during carotid artery stenting. A 73-year-old man with left cervical carotid artery stenosis presented with left amaurosis fugax. We performed carotid artery stenting using distal embolic protection with balloon occlusion. Dual antiplatelet therapy was maintained in the periprocedural period and an anticoagulant agent was administered during the procedure. Because the aspiration catheter became entrapped by the stent, it did not reach the distal side of the stenotic lesion, and manual compression of the cervical region was therefore performed. Immediately afterwards, a subcutaneous hemorrhage occurred in the cervical region. There was no postoperative dyspnea due to enlargement of the hematoma, which was absorbed spontaneously. Cervical subcutaneous hematoma can occur in the cervical region due to cervical massage in patients who are receiving adjuvant antiplatelet therapy and anticoagulation therapy.

We investigated serial changes of circulation platelet activation markers in 40 patients undergoing carotid artery stenting under the protection of dual antiplatelet therapy and filter devices. Monocyte-platelet aggregates and PAC-1 (a marker specific for activated glycoprotein IIb/IIIa) analyzed by flow cytometry were determined in patients with symptomatic stenosis undergoing elective carotid artery stenting. Blood samples were obtained immediately before stent implantation and 0.5 hours, 18 hours, and 6 days after the procedure, respectively. All patients were already on dual antiplatelet therapy of aspirin and clopidogrel before carotid artery stenting, and all were stented with embolic protection devices. Both circulation monocyte-platelet aggregates and PAC-1 did not change significantly at the various time points after the procedure. Serial changes of monocyte-platelet aggregates and PAC-1 analyzed by flow cytometry fail to indicate the occurrence of platelet activation after carotid artery stenting under the treatment with dual antiplatelet therapy before carotid artery stenting and the application of embolic protection devices during the procedure.

Background: The occurrence of early post-procedural complications after carotid artery stenting (CAS) can be attributed to embolization of thrombus or plaque particles released from the stented segment. Vascular emboli can be non-invasively detected by transcranial Doppler ultrasound as microembolic signals (MES). We performed this study to discover factors predicting MES detected by transcranial Doppler (TCD)-monitoring within the early post-interventional phase. Patients and methods: In 134 consecutive patients undergoing CAS, transcranial Doppler monitoring of the ipsilateral middle cerebral artery was performed for MES detection during the first post-interventional hour. To identify clinical, morphologic, and procedure-related parameters likely to predict the occurrence of post-interventional MES a logistic regression analysis was performed. Results: In 134 patients (111 male, mean age 69.7 years) relevant MES were detected in 51 patients (38 %) with a median of 4 MES/h and a maximum of 62 MES/h. Three factors were observed to be associated with increased post-interventional MES-counts. These included symptomatic lesion (p < 0.05), elevated total cholesterol (p < 0.05), and aspirin monotherapy (p < 0.0005). In a binary logistic regression model, dual antiplatelet therapy (OR 5.6, p < 0.0005) and asymptomatic lesions (OR 2.6, p < 0.05) were revealed as independent predictors for the absence of post-interventional MES. Conclusions: Post-interventional MES were most likely in symptomatic lesions and patients with elevated cholesterol. The absence of an effective dual antiplatelet therapy and symptomatic lesions were revealed as independent predictors for post-interventional MES. An effective pre-interventional dual antiplatelet and lipid lowering therapy might improve the safety of CAS.

OBJECTIVECarotid artery stenting (CAS) has been considered to prevent ischemic strokes caused by stenosis of the cervical carotid artery. The most common complication of CAS is new cerebral infarction. The authors have previously reported that the jellyfish sign—the rise and fall of the mobile component of the carotid plaque surface detected by carotid ultrasonography—suggests thinning and rupture of the fibrous cap over the unstable plaque content, such as the lipid-rich necrotic core or internal plaque hemorrhage. The authors’ aim in the present study was to evaluate the risk of a new ischemic lesion after CAS by using many risk factors including calcification (size and location) and the jellyfish sign.METHODSEighty-six lesions (77 patients) were treated with CAS. The presence of ischemic stroke was determined using diffusion-weighted imaging (DWI). Risk factors included calcification of the plaque (classified into 5 groups for size and 3 groups for location) and the jellyfish sign, among others. Multiple linear regression analysis (stepwise analysis and partial least squares [PLS] analysis) was conducted, followed by a machine learning analysis using an artificial neural network (ANN) based on the log-linearized gaussian mixture network (LLGMN). The additive effects of the jellyfish sign and calcification on ischemic stroke after CAS were examined using the Kruskal-Wallis test, followed by the Steel-Dwass test.RESULTSThe stepwise analysis selected the jellyfish sign, proximal calcification (proximal Ca), low-density lipoprotein (LDL) cholesterol, and patient age for the prediction model to predict new DWI lesions. The PLS analysis revealed the same top 3 variables (jellyfish sign, proximal Ca, and LDL cholesterol) according to the variable importance in projection scores. The ANN was then used, showing that these 3 variables remained. The accuracy of the ANN improved; areas under the receiver operating characteristic curves of the stepwise analysis, the PLS analysis, and the ANN were 0.719, 0.727, and 0.768, respectively. The combination of the jellyfish sign and proximal Ca indicates a significantly increased risk for ischemic stroke after CAS.CONCLUSIONSThe jellyfish sign, proximal Ca, and LDL cholesterol were considered to be important predictors for new DWI lesions after CAS. These 3 factors can be easily determined during a standard clinical visit. Thus, these 3 variables—especially the jellyfish sign and proximal Ca—may be useful for reducing the ischemic stroke risk in patients with stenosis of the cervical carotid artery.
