Summary
Retrieving OptEase vena cava filters after prolonged implantation is feasible using specialized techniques. These methods successfully removed filters without complications, even after extended indwelling periods.
Area of Science:
- Vascular surgery
- Interventional radiology
Background:
- The OptEase vena cava filter is designed for short-term use due to potential incorporation.
- Prolonged indwelling may lead to neointimal hyperplasia and filter embedding.
Purpose of the Study:
- To assess the feasibility and safety of retrieving OptEase filters with extended indwelling times.
- To evaluate the effectiveness of unconventional retrieval techniques.
Main Methods:
- Retrospective review of patients undergoing OptEase filter retrieval with long indwelling times.
- Utilized techniques such as rigid forceps dissection and wire-loop snares.
- Post-retrieval venography and clinical follow-up were performed.
Main Results:
- Three patients with a mean indwelling time of 6.4 months underwent successful retrieval.
- No complications were observed during or after the retrieval procedures.
- Clinical follow-up at two weeks showed no adverse events.
Conclusions:
- Unconventional retrieval techniques are effective for removing OptEase filters with long indwelling times.
- Extended indwelling of OptEase filters can be managed safely with specialized approaches.

01:28Angle Closure Glaucoma: Treatment
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...
01:23Ophthalmic Drug Delivery Systems
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
01:25Glaucoma: Overview
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...
