carotid cavernous

Anup Singh, Kapil Sikka, Nishchint Jain, Leve Joseph Devarajan
Endovascular treatment is a standard mode of treatment for traumatic cavernous internal carotid artery (ICA) pseudoaneurysms with good results and relatively low rates of complications. We describe a case of an unusual, potentially fatal, delayed postoperative event happening in a case of post-traumatic pseudoaneurysm of ICA, which had been previously managed with endovascular coiling.

Background: Currently, transsphenoidal surgery (TSS) is the preferred method for surgical treatment of intrasellar pituitary adenomas. However, it carries some risk of intraoperative arterial injuries, which is mainly attributed to direct iatrogenic rupture of the internal carotid artery (ICA). There is anecdotal evidence suggesting that intracranial aneurysms are coincidentally found significantly more frequently in the setting of pituitary adenomas than when the incidence is compared to other intracranial neoplasms...

PURPOSE: A complicated course of the femoral route for neurointervention can prevent approaching the target. Thus, we determined whether transcervical access in the hybrid angiosuite is applicable and beneficial in real practice. METHODS: From January 2014 to March 2017, this approach was used in 17 of 453 (3.75%) cases: 11 cerebral aneurysms (4 ruptured, 7 unruptured), 4 acute occlusions of the large cerebral artery, 1 proximal internal carotid artery (ICA) stenosis, and 1 direct carotid cavernous fistula (CCF)...

Intracranial hemangiopericytomas (HPC) are chemotherapy- and radiotherapy (RT)-resistant. Here, we report on a novel stereotactic radiosurgery (SRS) technique-"Cor Occidere" (Latin), as a potential strategy of overcoming radioresistance of HPC. A 36-year old female presented to our clinic for consideration of a 3rd-course of RT for her recurrent cavernous sinus HPC, following previous cranial RT at 13 and 5 years prior, and a failed 9 months trial of bevacizumab/temozolomide. The tumor-adjacent brain stem and carotid artery risked substantial damage given the cumulative RT doses to these organs...

BACKGROUND: Nontraumatic pseudoaneurysms of the cranial base are rare and present unique diagnostic and treatment dilemmas compared with both true aneurysms and pseudoaneurysms outside of the cranial base. There is a dearth of knowledge regarding the management of these complicated lesions. METHODS: Nontraumatic pseudoaneurysms of the cranial base internal carotid artery (ICA) were retrospectively identified at the University of Pittsburgh Medical Center through a key word search of cranial base cases from 2010 to 2017...

Background: Direct, Type A, cavernous-carotid fistulas (CCFs) are predominantly caused by head trauma, especially when basilar skull fractures are present. Transarterial endovascular treatment of direct CCFs is the preferred method of treatment. Bilateral CCFs are estimated to be present in 1-2% of the cases. The treatment of bilateral CCFs is difficult often requiring a combination of endovascular and open surgical approaches. Case Description: We present a case of traumatic bilateral CCFs presenting with vasospasm of the anterior circulation seen on the initial angiogram on day 1 and our treatment paradigm...

BACKGROUND: Cavernous carotid aneurysm (CCA) represents 2-9% of all intracranial aneurysms and 15% of internal carotid artery (ICA) aneurysms; additionally, giant aneurysms are those aneurysms that are > 25 mm in size. Bilateral CCAs account for 11-29% of patients and are commonly associated with structural weaknesses in the ICA wall, secondary to systemic hypertension. CCAs are considered benign lesions, given the low risk for developing major neurologic morbidities (i.e., subarachnoid hemorrhage, cerebral infarction, or carotid cavernous fistula)...

PURPOSE: Endovascular treatment of bifurcation aneurysms is difficult and complicated because arterial branches may arise from the aneurysmal neck. We treat these cases with complex techniques such as Y or T stenting. In this report, we deployed one Neuroform EZ stent using the intentional herniation technique for the preservation of arterial branches. CASE PRESENTATION: A 78-year-old female presented with two unruptured aneurysms. One was an 8 mm aneurysm located at the bifurcation of the internal carotid artery and the posterior communicating artery (PcomA)...

BACKGROUND: Balloon test occlusion (BTO) is a useful examination to evaluate the indications and methods for revascularization when treating unclippable internal carotid artery (ICA) aneurysms by parent artery occlusion. The purpose of the present study was to investigate the relationship between intraoperative monitoring of cerebral cortical blood flow (CoBF) and middle cerebral artery (MCA) pressure during surgical parent artery occlusion and the findings of BTO. METHODS: Eleven patients with an ICA aneurysm in the cavernous portion underwent preoperative BTO with brain perfusion single-photon emission tomography...

A delayed aneurysm rupture after flow diverter therapy is a rare but serious complication. Due to the anatomical specificity, a delayed rupture of a carotid cavernous aneurysm may cause a direct carotid cavernous fistula (dCCF). We present a novel therapeutic approach for treatment of dCCF after flow diverter therapy using the Pipeline embolization device (PED). An 86-year-old woman suffered from dCCF after PED embolization. A microcatheter was advanced through the transvenous approach into the cavernous sinus (CS) and further inserted into the aneurysm sac via the rupture point...

We describe the case of an 83-year-old woman with left-sided ophthalmoplegia. She had no family history of connective tissue disease. The computed tomography study found a dilated left cavernous sinus. The conventional cerebral panangiography confirmed the diagnosis - a direct carotid-cavernous fistula (CCF), with no evidence of ruptured aneurysm. The woman underwent endovascular treatment with coiling of the cavernous sinus in combination with application of the Onyx embolic agent in the fistula. During the first 48 hours after the embolization the local pain, exophthalmos and conjunctival injection of the left eye were significantly ameliorated...

BACKGROUND Carotid cavernous fistulas (CCFs) are rare potentially sight-threatening abnormal connections between carotid artery and cavernous sinus. CASE REPORT We report a case of CCF in an 83-year-old female, who presented with swollen and painful right eye. The patient was initially treated with empiric antibiotics for suspected peri-orbital cellulitis, as noted clinically and in computed tomography (CT) orbits. However, lack of clinical improvement, physical finding of orbital bruit/thrill, and enlarged superior ophthalmic vein in magnetic resonance (MR) orbits suggest alternate diagnoses...
