A giant intracranial internal carotid artery(ICA)aneurysm is difficult to treat. We encountered a case with an unruptured giant intracranial ICA aneurysm with a ruptured C2 aneurysm of the ipsilateral ICA. In this case report, we describe how the treatment and review the literature. A 59-year-old man presented with sudden-onset headache and vomiting. He was diagnosed at a local neurosurgical unit as having a subarachnoid hemorrhage and admitted to our hospital. Cerebral angiogram revealed an unruptured giant ICA C3-4 aneurysm with a ruptured aneurysm of the ipsilateral ICA C2...

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: Aneurysms of the external carotid artery represent approximately 2% of cervical carotid aneurysms, with the majority being traumatic pseudoaneurysms. Given the paucity of literature available for guidance, the diagnosis, treatment, and follow-up of such lesions are completely individualized. CASE DESCRIPTION: We report an 83-year-old woman with an 8-week history of headache in the occipital region, transient episode of gait disturbance, and pulsatile tinnitus on the right...

Bilateral cavernous carotid aneurysms (CCAs) are often not amenable to neurosurgical clipping or endovascular coiling. Here, we report the case of a 50-year-old female who presented with a 1-year history of gradual severe headache. Preoperative angiograms revealed bilateral CCAs. Among these findings, the right giant CCA had been trapped after the external carotid artery-saphenous vein-middle cerebral artery (ECA-SV-MCA) bypass 8 years prior. Additionally, the left CCA was again trapped after the internal maxillary artery-radial artery-middle cerebral artery (IMA-RA-MCA) bypass, followed by parent artery occlusion (PAO), because of the enlargement of a 0...

Carotid body tumors originate from paraganglionic tissue in the bifurcation of the common carotid artery. Magnetic resonance imaging is a frequently used diagnostic method in the preoperative diagnosis of these tumors and provides appropriate information for surgical planning. In this study, the authors emphasize magnetic resonance imaging and magnetic resonance angiography findings of the external carotid artery aneurysm associated with carotid body tumor. This highlights that the diagnosis of carotid artery aneurysms is essential to avoid accidental injury to the vessel during tumor surgery...

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...

BACKGROUND: The goal of the treatment of direct carotid cavernous fistula (CCF) is to occlude the arteriovenous shunt and to preserve the patency of the concerned internal carotid artery. However, for the ipsilateral posttraumatic fragile cerebrum, coil embolization plus parent artery occlusion for the high-flow direct CCF is better for the prevention of hyperperfusion syndrome and intracranial hemorrhage. We experienced such a case and managed it successfully. CASE DESCRIPTION: A 6-year-old boy had severe head trauma caused by being hit by a car...

Arresting or regressing growth of abdominal aortic aneurysms (AAAs), localized expansions of the abdominal aorta are contingent on inhibiting chronically overexpressed matrix metalloproteases (MMPs)-2 and -9 that disrupt elastic matrix within the aortic wall, concurrent with providing a stimulus to augmenting inherently poor auto-regeneration of these matrix structures. In a recent study we demonstrated that localized, controlled and sustained delivery of doxycycline (DOX; a tetracycline-based antibiotic) from poly(lactic-co-glycolic acid) nanoparticles (PLGA NPs), enhances elastic matrix deposition and MMP-inhibition at a fraction of the therapeutically effective oral dose...

Extracranial internal carotid artery (ICA) aneurysms located at the entrance of the skull are a rare pathology. Surgical treatment is indicated for this pathology because of the risk of arterio-arterial embolism and the development of cerebrovascular disease. The domestic and international literature reports single cases or small group cases of successful surgical treatment of patients with distal internal carotid artery aneurysms associated with pathological kinking of the artery. Open surgery for aneurysms of this localization is complicated because of a high injury risk associated with the approach...

Preoperative embolization of meningiomas can be safely performed using a variety of embolic agents. Most commonly, the vascular supply from branches of the external carotid artery is the target of embolization. In our report, we detail the treatment of a patient with a parafalcine meningioma that received its supply via branches of the anterior cerebral artery. One of the feeder vessels appeared to contain a dysplastic aneurysmal dilatation of the vessel. Due to patient circumstances, embolization was performed using standard microcatheterization techniques to minimize intraoperative blood loss...

The authors describe a case of a basilar trunk aneurysm with long-term follow-up after successful bypass and proximal occlusion. A 64-year-old woman had a giant aneurysm of the basilar trunk and underwent external carotid artery-to-posterior cerebral artery vein graft bypass surgery and proximal clipping of the basilar artery, which was followed by low-dose aspirin (100 mg/d) treatment. No ischemic symptoms and lesions developed and the thrombosed aneurysm was stable during 11 years of follow-up. An extracranial-intracranial high flow bypass combined with immediate proximal occlusion and aspirin administration may be an acceptable treatment option for patients with giant posterior circulation aneurysms...

AIM: Managing ruptured giant internal carotid artery (ICA) aneurysms in an emergency situation is very challenging. By reporting two cases, we discuss the role of the Excimer Laser-assisted Non-occlusive Anastomosis (ELANA) technique as an armamentarium for cerebrovascular surgeons dealing with giant ICA aneurysms presenting with subarachnoid hemorrhage (SAH). MATERIALS AND METHODS: The management of two consecutive patients treated with ELANA bypass during a 6-month period (June- December 2013) for ruptured giant ICA aneurysms in an emergency setting is presented...

BACKGROUND: Surgical clipping of paraclinoid aneurysm can be very difficult because strong adhesions may hinder the dissection of the perforators and surrounding anatomical structures from the aneurysm dome. We describe our experience with using retrograde suction decompression during the clipping of paraclinoid aneurysms and discuss the relative advantages and pitfalls. MATERIALS AND METHODS: This study included 23 patients with large and giant paraclinoid aneurysms who underwent surgical treatment consisting of direct clipping with suction decompression between March 2004 and August 2014...

INTRODUCTION: Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder characterized by café-au-lait macules, neurofibromas, and iris hamartomas. Carotid artery aneurysms rarely affect patients with NF-1 but may be associated with rupture. We report the first episode of a ruptured external carotid aneurysm with severe life-threatening airway obstruction in a NF-1 patient. PRESENTATION OF CASE: We report a case of NF-1 32-year-old woman admitted to our department for life-threatening upper airway obstruction caused by spontaneous expanding swelling in the left sided neck...

PURPOSE: To understand whether the use of antiplatelet agents leads to less intra-aneurismal tissue formation following coil implantation in a rat end-pouch external carotid artery (ECA) aneurysm model. METHODS: End-pouch ECA aneurysms were created in adult rats and were then embedded with either platinum or HydroCoils. Rats were treated either with aspirin, clopidogrel, aspirin + clopidogrel, or saline for 2 weeks after coil implantation. At 2 weeks after coil implantation, rats were sacrificed and the aneurysm pouch was removed for histological and immunohistochemical analysis...

Distinct origins of the external carotid artery and the internal carotid artery (ICA) from the aortic arch have been rarely described, and represent an aberrant development of the aortic arches during fetal life. This anatomical variation is usually discovered incidentally; infrequently, an aneurysm of the cervical ICA might accompany this rare configuration. We describe one such case in a patient with Noonan syndrome who presented with pulsatile neck mass. The diagnostic features and management of the aneurysm and a review of the literature are presented...

PURPOSE: Selective antegrade cerebral perfusion (SACP) involving cannulation of either the axillary or innominate artery is a commonly used technique for maintaining cerebral blood flow (CBF) during the use of hypothermic cardiac arrest (HCA) for operations on the aortic arch. Nevertheless, asymmetrical CBF with hypoperfusion of the left cerebral hemisphere is a common occurrence during SACP. The purpose of this report is to describe an adjunctive maneuver to improve left hemispheric CBF during SACP by applying extrinsic compression to the left carotid artery...
