Summary
Flow diversion is a safe treatment for carotid-ophthalmic aneurysms, with low risk of visual loss. Most aneurysms treated with flow diversion achieved complete occlusion, showing effectiveness.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Interventional Radiology
Background:
- Ophthalmic segment aneurysms pose treatment challenges.
- Endovascular techniques are common but visual outcomes are a concern.
Purpose of the Study:
- To evaluate the safety and efficacy of flow diversion for carotid-ophthalmic aneurysms.
- To assess visual, clinical, and angiographic outcomes after flow diversion treatment.
Main Methods:
- Retrospective review of 48 patients (50 aneurysms) treated with flow diversion from 2009-2015.
- Analysis of visual outcomes, complications, stroke, hemorrhage, and clinical follow-up.
- Angiographic assessment at 6 months, 1 year, and 3 years using angiography and MRA.
Main Results:
- No permanent adverse visual outcomes were observed.
- Complete angiographic occlusion rates were 64.9% at 6 months and 96% at 3 years.
- One case of late intraparenchymal hemorrhage resulted in death (2.2% mortality).
Conclusions:
- Flow diversion is a safe and effective treatment for select carotid-ophthalmic aneurysms.
- The risk of visual complications is low with this endovascular approach.
- High rates of aneurysm occlusion support the long-term efficacy of flow diversion.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

01:28Angle Closure Glaucoma: Treatment
1.6K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

01:27Open Angle Glaucoma: Treatment
1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:25Glaucoma: Overview
1.6K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
