DAVF is an abnormal connection between arteries and veins, where supply is mainly through branches arising from the external carotid artery. A 30 years old male had multiple episodes of seizures and progressive behavioral and cognitive decline, inattention and disorientation to time, place and person, along with ptosis and ophthalmoplegia in the right eye. DSA provided a definitive diagnosis of hypervascular Dural AV fistula at the right transverse sigmoid junction with significant cortical venous hypertension. Through femoral access, both underwent transarterial embolization through the Middle Meningeal branch of the right external carotid artery using onyx, resulting in complete occlusion of fistula and resolution of venous hypertension. Post embolisation, cognitive function assessment revealed increased attention span and improved orientation with time, place and person. Thus, DAVF can be one of the rare but reversible causes of dementia. Early diagnosis and treatment may help to dramatically improve patients’ clinical condition and minimize long-term disability.

Carotid Cavernous Fistulas

✓ The authors present a patient with a complex vascular malformation composed of bilateral spontaneous carotid-cavernous fistulas (CCF's). The abnormality was supplied on the right side by the right external carotid artery (ECA) and the right internal carotid artery (ICA), and on the left side only by the left ICA. There was also an arteriovenous communication between the right ECA and the lateral sinus. Surgical embolization of both cavernous sinuses with oxidized cellulose was achieved on one side by direct puncture and on the other through one of its venous affluents, successfully occluding both CCF's and preserving the patency of both ICA's without any neurological deficit. The arteriovenous communication between the right ECA and the lateral sinus was occluded by embolization of the occipital artery and ligation of the right ECA.

Trauma-induced arteriovenous (av) communications in the cervical region involving the external carotid artery and the jugular vein are exceptionally rare. Moreover, an iatrogenic av fistula between the vertebral artery and the vein after insertion of a venous catheter into the internal jugular vein is described. The discussion includes the clinical presentation, diagnosis and management of such rare av fistulas.

ABSTRACTVariations in the position of the bifurcation of the common carotid artery and the origin or branching pattern of the external carotid artery are well known and documented. Here, we report the trifurcation of the right common carotid artery in a male cadaver aged about 55 years. The right common carotid artery was found to divide into the external and internal carotids and the occipital artery. High division of bilateral common carotid arteries and a lateral position of the right external carotid artery at its origin were also observed in the same cadaver. There were two ascending pharyngeal arteries on the right side - one from the occipital artery and another from the internal carotid artery. The intraarterial approach is one of the most important routes for the administration of anticancer drugs for head and neck cancers. A profound knowledge of the anatomical characteristics and variations of the carotid artery such as its branching pattern and its position is essential to avoid complications with catheter insertion.

Objectives This study describes an alternative carotid bifurcation endarterectomy technique in which the external carotid artery is used as a suture patch. Methods Charts of ten patients with atherosclerotic carotid stenosis that were treated using the neobulb technique between 2002 and 2019 were reviewed. Results No major surgical adverse event was observed in the postoperative assessments. No postoperative common or internal carotid stenosis was observed in the mid- or long-term follow-up. Conclusions The neobulb technique allows carotid endarterectomy closure without a synthetic or venous patch, using the external carotid artery as an autologous patch, while preserving distal flow into the external carotid artery branches.

The well-known porcine arteriovenous malformation (AVM) model introduced by Massoud et al has been widely used as an acute-phase model. However, there are no data available on the patency rate in long-term follow-up. Therefore this study is dedicated to the natural history of porcine AVM model after creation. Three piglets (Yucatan micropigs, aged 12 to 14 months) were used in this study. The model was created by microsurgical anastomosis in an end-to-end fashion between the common carotid artery (CCA) and external jugular vein (EJV) on the left side, and by direct ligation of the left external carotid artery (ECA). Angiography was performed before and immediately after model creation, as well as at 44, 103, 188 and 245 days in all animals. A successful high-flow brain AVM model was established in all animals. The fistula created by end-to-end anastomosis remained intact and thus the successful AVM model maintained in all models over a follow-up period as long as more than eight months. The AVM-model in swine could be used as a chronic model to test the neurointerventional techniques of AVM treatment. We re-created the well known AVM-model by a terminal anastomosis between CCA and EJV and we hypothesize that the good long-term patency of the model is related to the type of anastomosis performed between CCA and EJV.

One of the rare anomalies of the common carotid artery is the separate origin of the internal and external carotid artery. We present the case of a patient who was admitted to hospital for cerebral angiography to exclude an intracranial aneurysm. The DSA revealed a giant aneurysm of the right internal carotid artery and separate origins of external and internal carotid arteries from the aortic arch. To our best knowledge no similar case has previously been reported.

AbstractTotal or segmental agenesis of the internal carotid artery is a rare anomaly. The cervical portion of the internal carotid artery was absent in the right side of the patient who was carried out radical surgery due to recurrent oropharyngeal cancer. Post-operative venous digital subtraction angiography revealed that the remaining intracranial portion of the internal carotid artery was normally patent and supplied blood flow via ipsilateral external carotid artery. Otolaryngologist-Head and Neck surgeon should know such a vascular anomaly and avoid a disastrous result on dividing external carotid artery.

Limb Shaking

The external carotid artery (ECA) is one of the most important extracranial-to-intracranial sources of collateral circulation, contributing significantly to the cerebral blood flow especially when perfusion through the internal carotid artery (ICA) is compromised. Most of the endovascular studies so far have been dedicated to ICA, with little focus on the ECA. Limb-shaking transient ischemic attacks (TIAs) are a relatively rare manifestation of carotid artery disease that may present with repetitive shaking movements of the affected limbs. We report a case of an 80-year-old male with bilateral internal and contralateral external carotid artery occlusion who developed limb-shaking TIAs as a result of significant stenosis of the right ECA. Percutaneous revascularization of the ECA was performed by angioplasty and stenting. At the follow-up 12 months later, the patient remained neurologically intact with complete resolution of his symptoms. Stenting of the ECA should be considered as a reasonable alternative to conventional open repair especially in patients with contralateral carotid stenosis, insufficient circle of Willis, and significant comorbidities.

Abstract Right aortic arch in association with coarctation of the aorta and vascular ring is a rare anatomy. We present an infant with chromosome 22q11.2 deletion, who had the right aortic arch with retroesophageal aberrant left subclavian artery and left internal carotid artery. The left external carotid artery and right common carotid artery originated together from the ascending aorta as a bovine branch. The infant also had severe coarctation, which was prostaglandin dependent.

The Relationship

Evaluation of carotid bifurcation level and relationship of External Carotid Artery (ECA) with reference to adjacent anatomical landmarks is important in planning various surgical and radiological procedures related to the carotid arteries. The aim was to study the relationship of External Carotid Artery with reference to Adjacent Anatomical landmarks in cadavers. 60 cadavers - 52 male and 8 female embalmed with 10% formalin were dissected over the period of two years for this study. The distance between the origin and the termination of ECA was found to be in the range of 25–70 mm on the right side and in the range of 25–68 mm on the left side. The distance between the origin of ECA and the carotid tubercle was found to be in the range of 23–50 mm on the right side and in the range of 22–48 mm on the left side. The distance between the origin of ECA and the angle of the mandible was found to be in the range of 18–30 mm on the right side and in the range of 20–32 mm on the left side. The anatomical knowledge of relationship of External Carotid Artery with reference to adjacent anatomical landmarks is helpful for vascular surgeons to plan surgeries and prevent complications during various diagnostic and therapeutic procedures.
