Acute middle cerebral artery occlusion caused by spontaneous thrombosis of a small internal carotid artery aneurysm: illustrative case

Herein, the authors discuss a case of acute middle cerebral artery occlusion owing to spontaneous thrombus of a small internal carotid artery aneurysm. After acute phase MCO with mechanical thrombectomy, the authors treated acute phase MCO with mechanical thrombectomy, and secondary stroke prophylaxis containing warfarin potassium was initiated. Since the thrombus had disappeared from the left ICA aneurysm, the whole aneurysm was clarified by MRA, coil embolization was carried out, MRA's thrombus was outlined. LESSONS Aneurysms are infrequently uncovered proximal to occlusion sites during MT. If the proximal aneurysm is a potential embolic source, treatment of the proximal aneurysm may prevent strokes.

Emergency surgical removal of a migrated coil during embolization of a giant internal carotid artery aneurysm: illustrative case

BACKGROUND Coil migration during endovascular therapy for an intracranial aneurysm is unusual. OBSERVATIONS During embolization of a massive intracranial segment of the internal carotid aneurysm, the authors reported a case of immediate coil migration. Without any new neurological deficits, the patient's full recovery was made. paraphrasedoutput:LESSONS LESSONS removed migrated coil from a seemingly unfeasible endovascular retrieval attempt as an alternative recovery procedure. The operating suite should be able to prevent unnecessary transfer and provide more realistic-time visualization of the migrated coil.

The surgical management of pituitary apoplexy with occluded internal carotid artery and hidden intracranial aneurysm: illustrative case

BACKGROUND About 0. 6 percent to 12% of cases of pituitary adenoma are complicated by apoplexy, and over 6% of pituitary adenomas are comorbid aneurysms. OBSERVATIONS The authors chronicled the case of a 48-year-old man with a large pituitary adenoma with coexisting ICA occlusion. Interventional aneurysm embolization was carried out after endoscopic transnasal surgery and repeated computed tomography angiography revealed reversition of the left ICA after endoscopic tomography angiography, but not with a new-found aneurysm in the left posterior communicating artery. LESSONS can provide excellent results for patients with pituitary apoplexy accompanied by a rapid decline in neurological conditions. However, patients are at risk of such vascular disease as aneurysm as a result of increased pituitary adenoma or pituitary apoplexy, and gentle intraoperative intervention is required.

Large cavernous carotid artery aneurysm with spontaneous thrombosis: is there more to a change in morphology than there seems to be? Illustrative case

paraphrasedoutput:BACKGROUND The origins and endovascular treatment plan for spontaneously thrombosed unruptured cerebral aneurysms have yet to be elaborated. OBSERVATIONS The authors examined a 78-year-old woman who had substantial bilateral carotid artery aneurysms that triggered persistent intravascular coagulation and acquired factor XIII deficiency.

Repair of internal carotid artery injury with aneurysm clip during endoscopic endonasal surgery: illustrative case

BACKGROUND One of the most common and risky scenarios during an endoscopic endosal surgery is the iatrogenic injury of the internal carotid artery. This is the first review on the use of a Yasargil-type aneurysm clip to solve an ICA accident, preserving the artery's patency, and having a long-term follow-up. In comparison to clipping, the authors discuss the benefits and drawbacks of other vessel preservation techniques. OBSERVATIONS A visually impaired 56-year-old woman was diagnosed with a massive non-functional pituitary tumor that invaded the sphenoidal sinus, anterior and posterior ethmoidal cells, and both cavernous sinuses, with suprasellar extension and optochiasmatic compression. LESSONS & COLOR BRITISH ICA injury during endoscopic skull base surgery causes high mortality and morbidity; it is also difficult to maintain carotid flow when possible to minimize short-term and long-term damage.

Subdural hemorrhage in the posterior fossa caused by a ruptured cavernous carotid artery aneurysm after a balloon occlusion test

The following are examples: If you're looking for a unique natural history of cavernous aneurysms and based on anecdotal studies in the literature of subarachnoid hemorrhage or subdural hemorrhage from these aneurysms is justified and generally accepted. They discuss the potential mechanisms for this event and the literature relating to cavernous aneurysms, including why cavernous aneurysms cause such hemorrhages.

Risk factors for neurological worsening and symptomatic watershed infarction in internal carotid artery aneurysm treated by extracranial-intracranial bypass using radial artery graft

The aim of this research was to determine the risk of the symptomatic WI and neurological distress in patients treated by ECA-R-M 2 bypass for complicated ICA occlusion with therapeutic ICA occlusion. METHODS In 37 patients, the authors estimated the volumes of vessels and intraoperative MCA blood pressure. The authors' receiver operating characteristic curve analysis for continuous variables and the binary end point of the symptomatic WI performed by the authors. At discharge and the 12-month follow-up exam or last hospital visit, authors Then, the authors, compared the results between patients with and without neurological disease at discharge and without neurological impairment at discharge and without. The vessel diameter and intraoperative MCA pressure were found to have a role on neurological development in patients with complex ICA aneurysms treated by ECA-M2 bypass, according to the present study.

Ophthalmic artery aneurysm treated by surgical clipping and balloon-assisted temporary carotid occlusion

Aneurysm in a 29-year-old woman has been associated with a large broad-base right ophthalmic artery aneurysm. paraphrased balloon occlusion was performed during the surgery with simultaneous endovascular temporary carotid balloon occlusion. The balloon was deployed in the petrous carotid, and the distal durai ring was open showing the proximal neck. The aneurysm was completely dissected and clipped under temporary proximal carotid balloon occlusion and distal carotid clip occlusion.

Direct suction decompression and fenestrated clip reconstruction of complex paraclinoid carotid artery aneurysm: operative video and nuances of skull base technique

Extradural optic nerve decompression, extradural anterior clinoidectomy, incision of the falciform ligament to untether the optic nerve, and distal durai ring are all shown in this series. Although novel endovascular techniques continue to evolve, these microsurgical skull base techniques should continue to be included in the surgical arsenal for treating these vascular lesions of the complex cranial base.

Embolization of a giant pediatric, posttraumatic, skull base internal carotid artery aneurysm with a liquid embolic agent

Many aneurysms that have been posttraumatic, skull base aneurysms have been reported. For wide-necked, side-wall aneurysms, we decided to treat the aneurysm with a new liquid embolic agent. In a smaller artery in a pediatric patient, we expected this therapy would result in less morbidity than surgery and was less likely to obstruct the parent artery than placing a covered stent, particularly in a smaller artery. Compared to stent-assisted coil embolization, Liquid embolic agents have also decreased risk of recanalization and lower cost. 99% of the aneurysm was embolized with 9 cc of the liquid embolic agent after the patient was treated with loading doses of aspirin, clopidogrel bisulfate, and heparin. Onyx's price was less than the cost of coil embolization of similarly sized intracranial aneurysms at our hospital.
