Afemoral vascular closure device such as a stent or a mesh implant is usually usedfor the treatment of spider veins. The stent is a small metal or plasticcylinder that is implanted through the belly button or under the navel. It isoften placed above the dermis. If the size of the implant is too small to allowit to go through the skin, a mesh implant is used. A mesh implant consists of aring made of transparent plastic that is implanted in the dermis around thevein. The use of a vascular hemostasis device is preferred by many because ithas fewer complications as compared to other traditional procedures such asangioplasty and catheterization. In most of the randomized trial trials,patients who used angio-seal flap and manual compression were more successfulin eliminating their cardiovascular diseases or disorders.
Oneof the benefits of choosing a vascular closure device from a reputed medicalproduct manufacturer is the inclusion of a randomized trial. This implies thatthe manufacturer has conducted a series of studies comparing the devices withstandard equipment in an attempt to prove or disprove their effectiveness.Patients may choose to participate in either randomized or blinded trials inwhich they are randomly assigned to either the device or the control group. Inthe blinded trials, patients are not told that they are receiving a salinesolution instead of a balloon catheter and that the procedure is performed onlyon those sites that are covered by the vascular hemostat. The benefit of thistype of trial is that patients can perform the procedure under a physician'ssupervision and can make informed decisions regarding its suitability.
Anotherbenefit of a reputed medical device manufacturer is that it publishes allresults of trials on its website. In addition, these companies provide patientswith a detailed description of the types of patients who have participated inthe study and provided data on the results. In the case of a randomized trial,patients and doctors may work together to decide on the best vascular closingdevices. For instance, in a blinded trial, the patient can choose whether ornot to receive a device and will not be told about the device's effectivenessat a later date unless the patient decides to disclose this information.
