Effects of EDTA on End-Point Detection Methods

Effects of EDTA on End-Point Detection Methods

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...

Summary

MicroNester coils offer a cost-effective alternative for neurovascular procedures like parent artery sacrifice and dural arteriovenous fistula treatment. They provide comparable effectiveness to detachable coils, significantly reducing procedural costs.

Neurosurgery
Interventional Radiology
Vascular Medicine

Background:

Detachable balloons were removed from the US market in 2003, leading to increased use of coil embolization for parent artery sacrifice.
MicroNester pushable coils emerged as a potential adjunct to detachable coils for neurovascular pathologies.

Purpose of the Study:

To examine the utility of MicroNester pushable coils as a low-cost and effective adjunct in neurointerventional procedures.
To evaluate the use of MicroNester coils in treating selected neurovascular pathologies.

Main Methods:

Retrospective analysis of neurointerventional procedures from November 2003 to May 2008.
Identification of cases utilizing MicroNester coils and analysis of coil type, number, and treated pathologies.

Main Results:

MicroNesters were used in 26 cases, primarily for arterial sacrifice (21 cases) and transvenous embolizations (5 cases).
Average coil usage for artery sacrifice was 13 coils (10 MicroNesters); for transvenous embolizations, it was 30 coils (6 MicroNesters).
Specific pathologies treated included intracranial aneurysms, pseudoaneurysms, carotid cavernous fistulae, carotid blowout, arteriovenous malformations, and dural arteriovenous fistulae.

Conclusions:

MicroNesters are a cost-effective and effective alternative to detachable coils for parent artery sacrifice and transvenous occlusion of dural arteriovenous fistulas.
Their use can reduce procedural costs by $3600 to $6000.
While not ideal for all procedures due to being non-retrievable, they are valuable for specific indications.
