OBJECTIVE: To determine the natural history of dissecting aneurysm (DA) and whether DA is associated with an increased recurrent stroke risk and whether type of antithrombotic drugs (antiplatelets vs anticoagulants) modifies the persistence or development of DA. METHODS: We included 264 patients with extracranial cervical artery dissection (CAD) from the Cervical Artery Dissection in Stroke Study (CADISS), a multicenter prospective study that compared antiplatelet with anticoagulation therapy...

BACKGROUND: Information on the growth rate of the diameter of the residual dissected supra-aortic trunk after surgical repair of type A aortic dissection is limited. METHODS: We retrospectively reviewed 95 consecutive postsurgical patients with type A aortic dissection (acute, 91; chronic, 4) between 2005 and 2016 who were followed up with computed tomography. The diameter of the residual dissected supra-aortic trunk was measured by axial images and multiplanar reformatting, and the growth rate was calculated...

INTRODUCTION: Traumatic intracranial aneurysms in children are rare and may occur as the result of closed or penetrating head trauma. Their natural history seems to be more aggressive. Most traumatic aneurysms have complex shape, tending to have a large neck or even a fusiform morphology. CASE REPORT: We present a case of a traumatic carotid artery aneurysm in a 9-year-old girl that was successfully treated with pipeline embolization device. DISCUSSION: Due to its dissecting nature, wall friability and lack of a substantial neck can make surgical clipping and selective coiling difficult and risky...

A new method for covering the internal jugular vein and carotid artery after exposure of the cervical vascular axis subsequent to neck dissection is presented. To cover the most caudal part of the vascular axis, a platysma coli muscle flap is harvested from its most medial and inferior part of the neck in a caudally based fashion and is slightly rotated posteriorly up to 45°. In addition, a superiorly based sternocleidomastoid muscle flap involving the posterior half of the muscle after detachment of the clavicle head is harvested and rotated 45° anteriorly to cover the upper two thirds of the vascular axis...

BACKGROUND AND PURPOSE: Although most cervical dissections are managed medically, emergent endovascular treatment may become necessary in the presence of intracranial large-vessel occlusions, flow-limiting and long-segment dissections with impending occlusion, and/or hypoperfusion-related ischemia at risk of infarction. We investigated the role of emergent endovascular stenting of long-segment carotid dissections in the acute ischemic stroke setting. MATERIALS AND METHODS: We retrospectively studied long-segment carotid dissections requiring stent reconstruction with multiple tandem stents (≥3 stents) and presenting with acute (<12 hours) ischemic stroke symptoms (NIHSS score, ≥4)...

Background Hemicrania continua (HC) -like headaches have been rarely reported as symptomatic headaches, including cases secondary to cervical artery dissection. Case series We present five cases of HC-like headaches following cervical artery dissection, in three cases with specific indomethacin response. In two cases, comorbidity of fibromuscular dysplasia (FMD) was noted. Conclusion Carotid artery dissection may result in an HC-like headache syndrome. A specific response to indomethacin does not rule out dissection as underlying pathology...

BACKGROUND: Reliable reconstructive flaps require convenient vascular supply. Thus, precise description of the vascular patterns of external ear is not completely elucidated. OBJECTIVE: This anatomical study aims to provide comprehensive data of the arterial network of the auricular region, anastomosis, and patterns of arterial dependence regarding external ear subunits. MATERIALS AND METHODS: After dyed latex injections in the external carotid artery, eleven auricles have been carefully dissected to examine the vascular network of the auricular region...

Fibromuscular dysplasia (FMD), a disease well described in the renal and cerebrovascular circulations, also manifests in the lower extremity (LE) arteries. This study reports on the clinical presentation, imaging findings, and treatment of patients with LE FMD seen at a single center. Over a 7-year span, 100 of 449 patients with FMD had imaging of the LE arteries, of which 62 were found to have LE FMD (13.8% of the entire FMD cohort including patients with and without LE imaging). The majority of patients were women (96...

The infrahyoid muscles are involved in vocalisation and swallowing; among these, the sternothyroid muscle is derived from the common primitive sheet. The improper differentiation of this muscle may therefore result in morphological variations. We report an unusual variation found during the dissection of a 65-year-old male cadaver at the Sri Manakula Vinayagar Medical College, Madagadipet, Pondicherry, India, in 2015. An anomalous belly of the right sternothyroid muscle was observed between the internal jugular (IJ) vein and the internal carotid artery with an additional insertion into the tympanic plate and petrous part of the temporal bone and the presence of a levator glandulae thyroideae muscle...

Primary intraventricular hemorrhage (PIVH) is a rare type of hemorrhagic stroke that is poorly understood. We aimed to explore the features of this disease in Chinese population via an institutional prospective study. Adult patients diagnosed with PIVH from January 2013 to January 2016 were enrolled in this study. Data, including clinical variables, radiological features, and yield of angiography, were collected to evaluate the clinical features, etiological causes, and prognostic factors of this disease. A total of 67 patients (73...

In cases of acute stroke, differentiation between an occluded and a patent internal carotid artery (ICA) is crucial for diagnosis and management. Although computed tomography angiography (CTA) can be highly accurate in defining high-grade stenosis and ICA occlusions, misleading ICA occlusion patterns are not rare in acute stroke patients. We investigated the underlying causes of ICA pseudo-occlusions with CTA with respect to digital subtraction angiography (DSA). 11 out of 72 patients had pseudo-occlusion on CTA...

This article highlights an unusual and unilateral variation in the blood supply to the inferior portion of the thyroid gland observed on the right lobe during anatomy dissection course. The rare variation of the occurrence of two anomalous arteries: the middle thyroid artery and the aberrant accessory inferior thyroid artery, and one uncommon variant, the thyroid ima artery, was detected in an adult female cadaver. The two generally constant arteries, the superior thyroid artery and the inferior thyroid artery, have been found in their usual anatomical location...

It is difficult to treat large internal carotid aneurysms with simple surgical clipping. Here, we present a retrograde suction decompression (RSD) procedure for large internal carotid aneurysms using a balloon guide catheter combined with a blood-returning circuit and a superficial temporal artery to middle cerebral artery (STA-MCA) bypass.All patients underwent an STA-MCA bypass before the temporary occlusion of the internal carotid artery (ICA). A 6-French sheath was inserted into the common carotid artery (CCA), and a 6-French Patrive balloon catheter was placed into the ICA 5 cm past the bifurcation...

The article deals with the use of self-expanding stents for endovascular treatment in patients presenting with dissection of the common carotid artery, exemplified by two clinical case reports. In both cases, dissection of the common carotid artery developed after eversion carotid endarterectomy. Intimal detachment was eliminated in both cases by implanting self-expanding stents. These cases demonstrated possibilities of roentgen endovascular methods of treatment making it possible to successfully replace a repeat, technically difficult surgical intervention for iatrogenic dissection of the common carotid artery...

BACKGROUND: The best management of carotid artery dissection (CAD) is still controversial ranging from antiplatelet medication to open surgery or endovascular treatment. In this retrospective study, we assessed the safety and efficacy of endovascular stent angioplasty for the treatment of CAD. METHODS: From February 2006 to February 2016, 44 patients (28 women and 16 men, age range 25-65 years, mean 42) with CAD were included in this study. The internal carotid artery dissection was spontaneous in 32 patients and posttraumatic in the remaining 12 (in 1 case, it was bilateral)...
