CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Comparison Between Proximal Versus Distal Protection Devices in 287 Cases of Carotid Revascularization Using Angioplasty and Stenting: Periprocedure Complications, Morbidity, and Mortality

Francisco Hernández-Fernández, G. Parrilla, B. García-Villalba, M. Espinosa de Rueda, J. Zamarro, M. Garrote, A. Moreno

Background: Embolic protection devices may decrease periprocedural thromboembolic complications during carotid angioplasty and stenting (CAS). When using proximal-protection devices (PPDs), protection starts before crossing the lesion. However, in the medical literature, its use is scarcely reported compared with that of distal-protection filters (DPDs). The objective of this study was to compare periprocedure complications, morbidity, and mortality among 287 consecutive cases of CAS performed with PPDs or DPDs.

CARDIOVASCULAR AND INTERVENTIONAL RADIOLOGY. Embolization of Direct Carotid Cavernous Fistula With Onyx and Coils Under Transarterial Balloon Protection

Ying Yu, Qiang Li, Qinghai Huang, Yongwei Zhang, Yibin Fang, Yi Xu, Bo Hong, Wenyuan Zhao, Jianmin Liu

Purpose: Endovascular management with good preservation of the internal carotid artery (ICA) has become the first-line choice for the treatment of direct carotid cavernous fistulas (CCFs). Multiple treatments have been tried with variable success. This article elucidates the effectiveness and safety of embolization with Onyx and coils under transarterial balloon protection.

AMERICAN JOURNAL OF NEURORADIOLOGY. Emergency Cervical Internal Carotid Artery Stenting in Combination with Intracranial Thrombectomy in Acute Stroke

S. Stampfl, P.A. Ringleb, M. Möhlenbruch, C. Hametner, C. Herweh, M. Pham, J. Bösel, S. Haehnel, M. Bendszus and S. Rohde

Background and Purpose: In past years, thrombectomy has become a widely used procedure in interventional neuroradiology for the treatment of acute intracranial occlusions. However, in 10–20% of patients, there are additional occlusions or stenotic lesions of the ipsilateral cervical internal carotid artery. The purpose of this study was to evaluate the feasibility of emergency carotid artery stent placement in combination with intracranial thrombectomy and the clinical outcome of the treated patients.

AMERICAN JOURNAL OF NEURORADIOLOGY. Socioeconomic Disparities in the Utilization of Mechanical Thrombectomy for Acute Ischemic Stroke in US Hospitals

W. Brinjikji, A.A. Rabinstein, J.S. McDonald and H.J. Cloft

Background and Purpose: Previous studies have demonstrated that socioeconomic disparities in the treatment of cerebrovascular diseases exist. We studied a large administrative data base to study disparities in the utilization of mechanical thrombectomy for acute ischemic stroke.

AMERICAN JOURNAL OF NEURORADIOLOGY. Frequency of Discordance between Facet Joint Activity on Technetium Tc99m Methylene Diphosphonate SPECT/CT and Selection for Percutaneous Treatment at a Large Multispecialty Institution

V.T. Lehman, R.C. Murphy, T.J. Kaufmann, F.E. Diehn, N.S. Murthy, J.T. Wald, K.R. Thielen, K.K. Amrami, J.M. Morris and T.P. Maus

Background and Purpose: The clinical impact of facet joint bone scan activity is not fully understood. The hypothesis of this study is that facet joints targeted for percutaneous treatment in clinical practice differ from those with reported activity on technetium Tc99m methylene diphosphonate SPECT/CT.

AMERICAN JOURNAL OF NEURORADIOLOGY. Long Insular Artery Infarction: Characteristics of a Previously Unrecognized Entity

A. Tamura, T. Kasai, K. Akazawa, Y. Nagakane, T. Yoshida, Y. Fujiwara, N. Kuriyama, K. Yamada, T. Mizuno and M. Nakagawa

Background and Purpose: The infarctions arising in the long insular arteries of the M2 segment have been poorly described in the past. The purpose of this study was to investigate the incidence, clinical characteristics, and pathogenesis of long insular artery infarcts.

AMERICAN JOURNAL OF NEURORADIOLOGY. Pretreatment Advanced Imaging in Patients with Stroke Treated with IV Thrombolysis: Evaluation of a Multihospital Data Base

J.S. McDonald, J. Fan, D.F. Kallmes and H.J. Cloft

Background and Purpose: CT angiography, CT perfusion, and MR imaging have all been advocated as potentially useful in treatment planning for patients with acute ischemic stroke. We evaluated a large multihospital data base to determine how the use of advanced imaging is evolving in patients treated with intravenous thrombolysis.

AMERICAN JOURNAL OF NEURORADIOLOGY. Treatment of Acute Vertebrobasilar Occlusion Using Thrombectomy with Stent Retrievers: Initial Experience with 18 Patients

M. Espinosa de Rueda, G. Parrilla, J. Zamarro, B. García-Villalba, F. Hernández and A. Moreno

Background and Purpose: Acute vertebrobasilar occlusion is an ominous disease with few proved effective treatments. Experience with stent retrievers is scarce and limited to combined therapies (stent retrievers associated with previous intravenous fibrinolysis, intra-arterial thrombolysis, or other mechanical devices). We present our experience with 18 patients treated with direct thrombectomy by using stent retrievers.

AMERICAN JOURNAL OF NEURORADIOLOGY. Recanalization with Stent-Retriever Devices in Patients with Wake-Up Stroke

S. Stampfl, P.A. Ringleb, S. Haehnel, A. Rocco, C. Herweh, C. Hametner, M. Pham, M. Moehlenbruch, M. Bendszus and S. Rohde

Background and Purpose: Stent-retriever devices play an increasing role in the interventional treatment of acute stroke patients, because fast recanalization can be achieved. The purpose of this study was to evaluate the feasibility of stent-retriever recanalization in patients with wake-up stroke in the anterior circulation.

AMERICAN JOURNAL OF NEURORADIOLOGY. Interobserver Variability in Retreatment Decisions of Recurrent and Residual Aneurysms

J.S. McDonald, R.E. Carter, K.F. Layton, J. Mocco, J.B. Madigan, R.G. Tawk, R.A. Hanel, S.S. Roy, H.J. Cloft, A.M. Klunder, S.H. Suh and D.F. Kallmes

Background and Purpose: The degree of variation in retreatment decisions for residual or recurrent aneurysms among endovascular therapists remains poorly defined. We performed a multireader study to determine what reader and patient variables contribute to this variation.

AMERICAN JOURNAL OF NEURORADIOLOGY. Age-Related Trends in the Treatment and Outcomes of Ruptured Cerebral Aneurysms: A Study of the Nationwide Inpatient Sample 2001–2009

W. Brinjikji, G. Lanzino, A.A. Rabinstein, D.F. Kallmes and H.J. Cloft

Background and Purpose: Patient age substantially influences treatment decisions for ruptured cerebral aneurysms. It would be useful to understand national age-related trends of treatment techniques and outcomes in patients treated for ruptured cerebral aneurysm in the United States.
