BACKGROUND: Limited data exists on the durability and occlusion rate of treating extracranial cervical internal carotid artery pseudoaneurysms using the pipeline embolization device (PED) flow-diverting stent. METHODS: Three patients presenting with dissecting cervical internal carotid artery pseudoaneurysms were treated with the PED as the sole treatment modality. RESULTS: In all three patients, successful aneurysmal occlusion and parent vessel reconstruction occurred on immediate angiography and continued on 6-month follow-up...

BACKGROUND: Aortic arch disease is a challenging clinical problem, especially in high-risk patients, in whom open repair can have morbidity and mortality rates of 30% to 40% and 2% to 20%, respectively. Aortic arch chimney (AAC) stents used during thoracic endovascular aortic repair (TEVAR) are a less invasive treatment strategy than open repair, but the current literature is inconclusive about the role of this technology. The focus of this analysis is on our experience with TEVAR and AAC stents...

Neck dissection is routine for the management of cancers of the head and neck. Knowledge of anatomical variants in the carotid artery system at various levels of dissection should prevent inadvertent injury to major blood vessels, which can cause massive bleeding. We report a rare 180° sharp bend in the cervical course of the internal carotid artery at level II, which we found during a modified neck dissection.

Though the variations of vertebral artery are clinically asymptomatic yet abnormalities are of diagnostic importance either prior to vascular surgery in the neck region or in patients of intravascular diseases such as arteriovenous malformations or cerebral aneurysms. Therefore, the aim of the study is to bring out 2 variations in the configuration of vertebral artery and their clinical implication. During dissection of thorax of 2 female cadavers, 2 different variants of configurations of left vertebral arteries were observed...

We hereby report a novel technical approach for the treatment of acute stroke with underlying tandem occlusion. The so-called retriever wire supported carotid artery revascularization (ReWiSed CARe) technique, utilizing the wire of a stent-retriever as a guiding wire for carotid artery stenting, is technically feasible in tandem occlusions caused by an internal carotid artery (ICA) dissection or high grade ICA stenosis. This technique eliminates the need to use a long microwire in order to maintain the position inside the true lumen of a dissection...

BACKGROUND: Fibromuscular dysplasia (FMD) is an idiopathic, non-inflammatory, non-atherosclerotic vascular disease, resulting in focal narrowing of small and medium-sized arteries. Systematic recording of clinical data in central databases as in the US and France provided new insights into FMD. The main objectives of this multicentre study were to explore the epidemiology, pattern of vascular involvement, clinical manifestations, and management of FMD patients in Flanders. PATIENTS AND METHODS: Multicentre, retrospective registry of patients diagnosed with FMD based on medical imaging...

The internal jugular vein (IJV) is an important vascular structure for oncologists and radiologists and is also a frequently used central venous route. The variations in the pattern of its course, and knowledge of its variations, are important. During the anatomical dissection of a 70-year-old male cadaver, fenestration involving a short segment (2.5 cm) of the right IJV in the superior part of the carotid triangle and a large dilatation (phlebectasia) of the IJV, involving its nonfenestrated segment were found - a case that has not previously been reported...

Acute Stanford type A aortic dissection requires an extremely complex surgical strategy and presents high risk of complications. Although many different procedures were reported to treat this aortic dissection, high mortality rate and incidences of complications still exist. This study presents a 59-year-old lady with acute Stanford type A aortic dissection, which originated from the aortic root to proximal part of right external iliac artery and involved the brachiocephalic trunk, left carotid artery, celiac trunk, and left renal artery...

OBJECTIVE The rectus capitis lateralis (RCL) is a small posterior cervical muscle that originates from the transverse process of C-1 and inserts onto the jugular process of the occipital bone. The authors describe the RCL and its anatomical relationships, and discuss its utility as a surgical landmark for safe exposure of the jugular foramen in extended or combined skull base approaches. In addition, the condylar triangle is defined as a landmark for localizing the vertebral artery (VA) and occipital condyle...

The superior laryngeal artery is the principal artery supplying the laryngeal mucosa, musculature, and glands. Knowledge of variations in the origin of superior laryngeal artery could prove to be very useful during reconstructive surgeries of the larynx, partial laryngectomy, laryngeal transplantation, and also during procedures like super-selective intra-arterial chemotherapy for laryngeal and hypolaryngeal cancers. However, relatively few studies have been done on the superior laryngeal artery in comparison to its clinical importance...

Carotid artery dissection is an uncommon entity associated with head and neck pain, partial Horner's syndrome, amaurosis fugax, and brain ischemia, which may all occur in isolation or in combination. Herein, we report a rare case of cervical artery dissection in which pulsatile tinnitus was the only reported symptom. A 38-years-old man attended our hospital with a 4-days history of left side pulsatile tinnitus which began after stumbling. He had no other symptom. MRA showed luminal stenosis with pseudo lumen of the internal carotid artery...

BACKGROUND: Based on randomized trials, carotid endarterectomy (CEA) is the standard procedure for patients with a 50-99% symptomatic carotid stenosis and carefully selected patients with an asymptomatic high-grade carotid stenosis. Carotid artery stenting (CAS) is a technical alternative for patients with a high surgical risk or difficult anatomic conditions (e.g., recurrent stenosis). This study aims to provide an overview of anatomic factors associated with a higher risk of CEA complications...

Yong Sook Park, Taek Kyun Nam
We describe a technique to clip a large internal carotid artery (ICA) aneurysm via a retrograde suction decompression (RSD). A large aneurysm in the right distal ICA involving the bifurcation region measuring 1.2×1.1×0.7 cm with posterior projection was managed with assisted RSD technique. The anterior choroidal artery emerged from the side wall of the aneurysm. An Inahara shunt was inserted into the ICA with neck dissection, and RSD was applied after completely clipping the aneurysm. RSD with an Inahara carotid shunt is useful for complete visualization of the aneurysm, including its surrounding structures, and for proximal control of the parent vessels, subsequently achieving satisfactory clip placement...

BACKGROUND AND PURPOSE: Pseudo-occlusion (PO) of the cervical internal carotid artery (ICA) refers to an isolated occlusion of the intracranial ICA that appears as an extracranial ICA occlusion on computed tomography angiography (CTA) or digital subtraction angiography because of blockage of distal contrast penetration by a stagnant column of unopacified blood. We aim to better characterize this poorly recognized entity. METHODS: Retrospective review of an endovascular database (2010-2015; n=898)...

Symptomatic carotid artery atherosclerotic disease is an indication for carotid artery endarterectomy. The coexistence of carotid body tumors (CBTs) with symptomatic carotid disease is rarely encountered and adds significant challenges to vascular surgeons, with a reported overall mortality for patients who undergo endarterectomy and tumor excision of 8.8%, as opposed to the 2% for those who had CBT excision only. We describe the case of a 79-year-old female who experienced an acute cerebrovascular accident in the left hemisphere; duplex ultrasound revealed high-grade carotid stenosis in the left side and the presence of a Shamblin I CBT...

Takayasu's arteritis (TA) is a rare, idiopathic, chronic inflammatory disease associated with cell-mediated inflammation and involving predominantly the aorta and its primary branches. TA results in stenosis, occlusion or aneurysmal degeneration of large arteries pathologically. However, the incidence of dissection in arteries is low. As one of the primary causes of aortic dissection-associated ischemic stroke in young adults, only a limited number of TA cases presenting with aortic dissection have been published to date...

INTRODUCTION: Endarterectomized human atherosclerotic plaques are a valuable basis for gene expression studies to disclose novel imaging biomarkers and therapeutic targets, such as the cannabinoid receptor type 2 (CB2). In this work, CB2 is expressed on activated immune cells, which are abundant in inflamed plaques. We evaluated the CB2-specific radiotracer [(11)C]RS-016 for imaging vascular inflammation in human and mouse atherosclerotic lesions. METHODS: The differential gene expression of microscopically classified human carotid plaques was evaluated using quantitative polymerase chain reaction...
