Specifically in neck level IIb, the expected normal anatomy does not contain any vital structures and consequently it might direct a surgeon to perform rapid surgical dissection of tissues. Therefore aberrant anatomy of the vessels in the patients may be overlooked during neck dissection. Unexpected and potentially devastating injuries can be avoided by respecting the possible aberrant anatomy in any level of the neck. In this case report, a 74-year-old man was presented with laryngeal carcinoma who was treated with laryngectomy and bilateral neck dissection...

As classically described, Eagle syndrome is an entity where patients develop pain or neurologic manifestations arising from an elongated styloid process and/or an ossified stylohyoid ligament irritating or compressing adjacent cranial nerves or the carotid arteries. Over the past few years, there have been reports of actual injury to the internal carotid artery with dissection, occlusion and strokes. We present three cases identified after blunt trauma-one due to carotid compression and two due to actual injury to the internal carotid artery...

We sought to determine, with a retrospective chart review, the imaging yield for patients with clinically isolated Horner syndrome. MRI/MRA of the head and neck extending from the supraorbital ridge to T4 with fat suppression and with postcontrast images was obtained. Of 88 patients with isolated Horner syndrome who were imaged, 20% had a causative etiology on imaging. The most common cause of an isolated Horner syndrome was a carotid artery dissection. There was 1 patient with a primary malignancy found to be the causative lesion in this group, and 1 patient with spread of their known metastatic disease...

BACKGROUND: Chiropractic manipulation is a popular treatment for neck pain and headache, but may increase the risk of cervical artery dissection and stroke. Patients with carotid artery dissection can present with neck pain and/or headache before experiencing a stroke. These are common symptoms seen by both chiropractors and primary care physicians (PCPs). We aimed to assess the risk of carotid artery stroke after chiropractic care by comparing association between chiropractic and PCP visits and subsequent stroke...

Carotid or vertebral artery dissection is the result of a tear in the vessel lining wherein the intima separates the media. This creates a false or pseudo lumen, often accompanied by hemorrhage into the arterial wall. Dissection of these craniocervical vessels often manifests with pain alone but, if untreated, may result in severe neurologic compromise. The causes of dissection are multifactorial, including spontaneous, iatrogenic, and traumatic insults. Regardless of etiology, treatment consists primarily of anticoagulation, whereas endovascular therapy is reserved for cases with persistent thrombus or flow limitation...

AIM: Eagle syndrome is a rare entity that causes recurrent throat pain, neck pain, dysphagia, or facial pain by elongated styloid process or calcified stylohyoid ligament. Clinical findings related to the lower cranial nerves compression have also been reported. In some cases it is reported that carotid artery compression or dissection can be seen due to elongated styloid process and it is called carotid artery syndrome. Carotid artery compression causes flow reduction and carotidynia or neurological symptoms can be seen...

Paragangliomas are highly vascularized usually benign neoplasms originating from the sympathoadrenal and parasympathetic paraganglia of the autonomic nervous system. When resectable, the management of these tumors consists of surgical ablation preceded by transarterial embolization. The aim of this article is to describe a novel treatment strategy combining intralesional percutaneous embolization with dissection using ultrasound scissors. The case of a 74-year-old women presenting with a Shamblin type III carotid body paraganglioma is presented...

BACKGROUND: Carotid artery dissections have long been associated with compromise of the structural integrity of the arterial wall from heritable connective-tissue disorders, hypertension, and trauma. However, an association between spontaneous internal carotid artery dissection and tortuous or redundant carotid anatomy has not been fully explored. METHODS: Patients with CTA confirmed spontaneous cervical internal carotid artery dissections were compared to a group of age and sex matched controls who also received CTA of the neck...

Dissection of the internal carotid artery (ICA) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. Iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. In this report, a case of dissection of the ICA is reported that was caused by repetitive movement of the balloon guiding catheter during stent-assisted thrombectomy (SAT), resulting in occlusion of the ICA...

BACKGROUND: Cervical artery dissection (CAD) is a leading cause of ischemic stroke among middle aged adults, yet the aetiology remains poorly understood. There are reports from colder northern hemisphere sites of a seasonal pattern in the incidence of CAD. Seasonality may suggest some transient putative pro-inflammatory mechanism but it is unknown whether this also exists in temperate climates. AIMS: To investigate the seasonal variation in incidence of CAD in the xx Region, Australia, and to compare seasonal incidence and selected clinical features between cases of carotid and vertebral artery dissection...

CONTEXT: In surgical management of global brachial plexus injuries, direct repair of contralateral C7 (cC7) to the anterior division of the lower trunk, can produce good extrinsic finger flexion. The pitfalls associated with the pre-spinal passage have, perhaps, proved to be a deterrent for using this technique routinely. AIMS: The aim of this study is to demonstrate an alternative to pre-spinal route for cC7 transfer in brachial plexus avulsion injuries. METHODS: We noted that the mobilised lower trunk, which reaches the level of the scalenus anterior by passage deep to the clavicle, can be brought to the suprasternal notch when brought out from below the clavicle...

Cerebral hyperperfusion syndrome (CHS) is a rare complication following cerebral revascularization. It presents with ipsilateral headache, seizures, and intracerebral hemorrhage. It has mostly been described following extracranial carotid endarterectomy and stenting and it is very unusual after intracranial stenting. A 71-year-old man with a stuttering stroke was taken up for a cerebral angiogram (digital subtraction angiography), which showed a dissection of the distal left middle cerebral artery. This was recanalized with a solitaire AB stent...

Fibromuscular dysplasia (FMD) is a non-inflammatory, non-atherosclerotic vasculopathy that can lead to arterial stenosis, occlusion, aneurysms, and dissection. FMD of the renal arteries can lead to renovascular hypertension. Percutaneous angioplasty of the renal arteries (PTRA) can lead to normalization of blood pressure in 45% of patients with renal artery stenosis caused by FMD, particularly in younger patients and patients with a short history of hypertension. A considerable number of the patients with renovascular FMD also have cervical FMD, which can lead to ischaemic or haemorrhagic stroke...
