BACKGROUND: Although the term paraclival carotid pervades recent skull base literature, no clear consensus exists regarding boundaries or anatomical segments. OBJECTIVE: To reconcile various internal carotid artery (ICA) nomenclatures for transcranial and endoscopic-endonasal perspectives, we reexamined the transition between lacerum (C3) and cavernous (C4) segments using a C1-C7 segments schema. In this cadaveric study, we obtained a 360°-circumferential view integrating histological, microsurgical, endoscopic, and neuroradiological analyses of this C3-C4 region and identified a distinct transitional segment...

BACKGROUND: The distal dural ring (DDR) is a conserved intracranial anatomic structure marking the boundary point at which the internal carotid artery (ICA) exits the cavernous sinus (CS) and enters the subarachnoid space. Although the CS has been well described in a range of anatomic studies, to our knowledge no prior study has analyzed the histologic relationship between the ICA and DDR. Correspondingly, our objective was to assess the relationship of the DDR to the ICA and determine whether the DDR can be dissected from the ICA and thus divided, or can only be circumferentially trimmed around the artery...

Ischemic stroke is a rare yet devastating complication that may occur following cardiothoracic surgery. Fibrinolytic treatment is contraindicated due to elevated risk for hemorrhage. Mechanical thrombectomy entails a catheterized approach wherein the thrombus is physically removed from the vessel without the use of fibrinolytics, minimizing the possibility of intracranial hemorrhage. Here, we present two original cases of mechanical thrombectomy as treatment for patients experiencing emergent large vessel occlusion following cardiothoracic surgery...

Introduction Blunt head trauma can injure the cavernous segment of the internal carotid artery (ICA). This may result in a carotid cavernous fistula (CCF). Rarely, a traumatic aneurysm may bleed medially causing massive epistaxis. Case presentation We present two cases of traumatic intracavernous carotid pseudoaneurysms with delayed massive epistaxis. The patients were managed with endovascular treatment involving coil embolization with parent vessel sparing and detachable balloon occlusion with carotid sacrifice...

Cavernous carotid aneurysms (CCA) pose considerable dilemmas in management. It is still unclear as to whether an asymptomatic CCA should be subjected to treatment. Similarly, the ideal management strategy for a symptomatic aneurysm is controversial. We present the case of a 60-year-old female with a giant CCA and discuss the management issues.

OBJECTIVE: We reviewed our 7-year experience to assess the efficacy of stereotactic radiosurgery (SRS) for dural carotid cavernous fistulas (DCCFs). We analyzed the clinical outcome, complications and angiographic results. METHODS: We performed a retrospective analysis of 18 consecutive patients with DCCF treated by SRS alone using Gamma Knife between 2009 and 2015. Median target volume was 2.6 cm(3) (range, 0.6-11.6 cm(3)) and median radiation dose to the target was 17 Gy (range, 14-19 Gy)...

The internal carotid artery agenesis is a rare malformation disorder. We report the case of a 12-year-old boy suffering migraine, who had presented an episode featuring amaurosis fugax, spontaneously regressed. CT angiography images show hypoplasia of the left common carotid artery with loss of opacification of the left internal carotid artery consistent to agenesis. Moreover CT scans through the skull base demonstrate absence of left petrous carotid canal and an hypertrophic left middle cerebral artery originating from an aberrant artery arising from the right cavernous carotid...

BACKGROUND: Percutaneous ganglyolysis treatment of trigeminal neuralgia is rarely associated with vascular complications, such as hematoma, subarachnoid hemorrhage, and stroke. Internal carotid artery injury may also occur after misguided needle placement, particularly far posteriorly or medially, resulting in carotid cavernous fistula. Anatomical variations of the foramen ovale can predispose those complications. CASE DESCRIPTION: A young woman diagnosed with trigeminal neuralgia during 11 years was submitted to a balloon rhizotomy by percutaneous approach to the trigeminal ganglion, with severe intraoperative bleeding...

Persistent trigeminal artery (PTA) and its variant (PTAV) are the most prevalent types of carotid-vertebrobasilar anastomosis, but bilateral anastomoses are exceedingly rare. We report a case of a right PTAV and tiny left lateral-type PTA from which the cerebellar artery (presumed anterior inferior cerebellar artery) arose. And also, bilateral ophthalmic arteries arose from the cavernous segments of the internal carotid arteries and entered the orbits via the superior orbital fissures. Selective cerebral angiography, especially 3-dimensional angiography, is superior to magnetic resonance (MR) angiography to identify rare variations of the cerebral arteries...

BACKGROUND: Cavernous sinus (CS) tumors are often considered inoperable. We present our experience with endoscopic endonasal surgery (EES) and compare the outcomes for different tumor. METHODS: EES (medial or lateral approach) was used in 234 patients with CS tumors. The cohort included 175 (75%) pituitary adenomas and 59 (25%) non-adenomatous lesions. RESULTS: Presenting symptoms were significantly different between the two groups, with cranial neuropathies occurring mainly in non-adenomas (p<...

BACKGROUND: Intracranial arterial atherosclerosis represents a common cause of stroke. Despite aggressive and optimal medical management, many patients will unfortunately suffer additional cerebrovascular events. The role of endovascular intervention for intracranial atherosclerotic disease continues to be uncertain, particularly in regard to extensive, symptomatic stenosis. CASE DESCRIPTION: We present a case of a 42-year-old male with a complex medical history who presented with recurrent ischemic stroke in the ipsilateral hemisphere despite optimal medical management...

OBJECTIVE: Previously, cavernous angiomas(CAs)have been thought to be only congenital in origin. Recently, however, a few cases of de novo CAs have been reported in the literature. We present a case of a de novo CA and discuss the etiology of the newly appeared CA. CASE REPORT: A 29-year-old man was presented to a local clinic because of hypersomnia. MRI demonstrated a heterogeneous mass peripherally located, which was in contact with a developmental venous anomaly(DVA)at the left thalamus...

Artiodactyl cranial arterial patterns deviate significantly from the standard mammalian pattern, most notably in the possession of a structure called the carotid rete (CR)-a subdural arterial meshwork that is housed within the cavernous venous sinus, replacing the internal carotid artery (ICA). This relationship between the CR and the cavernous sinus facilitates a suite of unique physiologies, including selective brain cooling. The CR has been studied in a number of artiodactyls; however, to my knowledge, only a single study to date documents a subset of the cranial arteries of New World camelids (llamas, alpacas, vicugñas and guanacoes)...

PURPOSE: Arterial spin labeling (ASL) involves perfusion imaging using the inverted magnetization of arterial water. If the arterial arrival times are longer than the post-labeling delay, labeled spins are visible on ASL images as bright, high intra-arterial signals (IASs); such signals were found within occluded vessels of patients with acute ischemic stroke. The identification of the occluded segment in the internal carotid artery (ICA) is crucial for endovascular treatment. We tested our hypothesis that high IASs on ASL images can predict the occluded segment...

BACKGROUND: Although the natural course of extracranial carotid artery aneurysms (ECAAs) is still unknown, they may cause stroke or cranial nerve dysfunction unless they are treated. In this report, we reviewed the clinical results of 6 patients who underwent endovascular and surgical treatments for ECAAs. METHODS: A total of 6 patients underwent endovascular and surgical treatments for ECAAs for 9 years. The primary causes of ECAAs included Marfan syndrome (1 patient), infection (1 patient), trauma (2 patients), and unknown (2 patients)...

Background Carotid cavernous fistulas (CCFs) Barrow type 'B' are dural shunts between the meningeal branches of the internal carotid artery and the cavernous sinus. The symptoms include vision deterioration, ophthalmoplegia with diplopia, exophthalmos, conjunctival injection, chemosis, ocular bruit, seizures, or neurological deficit. Endovascular treatment remains the gold standard for treatment through the transvenous or transarterial routes. The transvenous approaches have been proved to be the first option...
