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

paraphrasedoutput:BACKGROUND BACKGROUND is one of the most common and risky situations during an endoscopic endosal surgery is the iatrogenic injury of the internal carotid artery. This is the first review of a Yasargil-type aneurysm clip used to fix an ICA injury, preserving the artery's patency, and having a long-term follow-up. Compared to clipping, the authors discuss the benefits and disadvantages of other vessel preservation techniques as well as clipping. OBSERVATIONS are the visual impairment of a mentally impaired 56-year-old woman was diagnosed with a massive nonfunctional pituitary tumor that invaded the sphenoidal sinus, anterior and posterior ethmoidal cells, and both cavernous sinuses, with suprasellar expansion and optochiasmatic compression. LESSONS RCA injury during endoscopic skull base surgery results in high mortality and morbidity; it is also essential to maintain carotid flow as long as possible to minimize short-term and long-term effects.

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 pathogenesis and endovascular treatment of spontaneously thrombosed cerebral aneurysms have not yet been fully described. OBSERVATIONS The authors investigated a 78-year-old woman who had significant bilateral carotid aneurysms that resulted in chronic poor intravascular coagulation and acquired factor XIII deficiency.

Comparison of hemodynamic stress in healthy vessels after parent artery occlusion and flow diverter stent treatment for internal carotid artery aneurysm

OBJECTIVE De novo aneurysms generally develop in healthy vessels following parent artery occlusion for significant internal carotid artery aneurysm, perhaps due to increased hemodynamic strain in the remaining vessels. METHODS The authors included patients who underwent 3D cine phase-contrast MRI before and after significant ICA aneurysm therapy. Before and after parental artery occlusion and flow diverter treatments, artery flow rates and spatially averaged systolic wall shear stress in a healthy-side ICA distal to the posterior communicating artery were determined. The flow diverter group, which went from 5. 36 ml/sec to 6. 28 ml/sec in healthy-side ICA, up from 6. 36 ml/sec to 6. 28 ml/sec after treatment, and from 4. 65 ml/sec to 4. 93 ml/sec in the flow diverter group at 1 u20132 months after release.

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

u2713Given the relatively benign natural history of cavernous aneurysms and based on anecdotal studies in the literature of subarachnoid hemorrhage or subdural hemorrhage from these aneurysms, anecdotal studies have been cited and generally accepted, and observation is warranted and often recommended. They discuss the potential mechanisms for this event and the literature related 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 purpose of the present study was to investigate the causes for the symptomatic WI and neurological progression in patients treated by ECA-M2 bypass for difficult ICA occlusion with therapeutic ICA occlusion. The authors conducted receiver operating characteristic curve analysis for continuous variables and the binary end point of a symptomatic WI. Patients with and without neurological impairment at discharge, as well as at the 12-month follow-up exam or last hospital visit, Then, the authors, compared the outcomes between patients with and without neurological impairment at discharge and without. The vessel diameter and intraoperative MCA pressure, according to the present study's findings, had an effect on the symptomatic WI and that operative side and percutaneous artery ischemia in patients with complicated ICA aneurysms treated by ECA-M2 bypass.

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

A 29-year-old woman is diagnosed with a large right ophthalmic artery aneurysm. paraphrased balloon occlusion was performed simultaneously endovascular temporary carotid balloon occlusion. The balloon was positioned in the petrous carotid, and the distal durai ring was opened showing the proximal neck. The aneurysm was completely dissected and clipped under temporary 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

Additionaldural optic nerve decompression, extradural anterior clinoidectomy, incision of the falciform ligament to untether the optic nerve, and the freeing of the distal durai ring to achieve proximal control are all shown in the following skull base techniques. Although novel endovascular procedures continue to evolve, these microsurgical skull base techniques should remain in the surgical arsenal for treating these complicated cranial base vascular lesions.

Hybrid vascular intervention for a giant cervical carotid artery aneurysm in a clopidogrel-hyporesponsive child

Extracranial internal carotid artery aneurysms in pediatric patients are unusual and predominantly treated surgically. The authors explore the case of a child with a massive extracranial ICA aneurysm presenting with gradual airway compression. If primary reconstruction of the carotid artery was not feasible, a strategy was developed to investigate the aneurysm surgically and straighten the underlying carotid artery kinks during the surgery to enable further endovascular therapy. A ngiogram performed by a craniocervical CT angiogram at 5 months demonstrated patency of the stent construction and airway compression relief. With prasugrel monotherapy, a child undergoing neurovascular intervention was unusual in terms of clopidogrel hyporesponsiveness in the first reported case of clopidogrel hyporesponsiveness in a child undergoing neurovascular intervention. Prioritizing crushing and contact with air, point-of-care testingu2013-based improvement of prasugrel necessitated that the patient's family be notified of the void of the prasugrel tablets's survival is necessitated.

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

Multiple aneurysm treatments have been described for posttraumatic, skull base aneurysms. This 12-year-old girl was diagnosed with right-side Horner syndrome caused by a 33 mm internal carotid artery aneurysm at the C-1 level, eight months after an all-terrain-vehicle crash. This therapy was less likely to result in less morbidity than surgery and was less likely to occlude the parent artery than the installation of a covered stent, especially in a small artery in a pediatric patient. Comparing to stent-assisted coil embolization, Liquid embolic agents also appear to have a reduced chance of recanalization and lower cost than stent-assisted coil embolization. With 9 cc of the liquid embolic agent, 99% of the aneurysm was embolized after the patient was treated with loading doses of aspirin, clopidogrel bisulfate, and heparin. Pediatric patients with select massive, posttraumatic, skull base aneurysms can be treated by Liquid embolic agents in a safe, cost-effective, and cost-effective way.

Early surgical versus endovascular repair of ruptured blood-blister aneurysm of the internal carotid artery: a single-center 20-year experience

The authors analyzed their single-center experience and compared early deconstructive to reconstructive repair, and early reconstructive surgical versus endovascular repair of ruptured BBAs of the ICA. METHODS The study included patients who underwent repair of ruptured BBAs of the ICA within 1 week of the ictus following the 20-year period. In 5 of 6 patients, middle cerebral artery territory infarction was followed by a high mortality rate, and primary reconstructive reconstruction without bypass was followed by a high mortality rate. Surgery was performed in 11 patients and endovascular repair in ten patients among the 21 patients who underwent early reconstructive surgery. Reconstructive therapy is preferable to ICA sacrifice, and if sacrifice is chosen, it should be followed by bypass surgery or postponed to the point when cerebral vaping has returned to normal.
