What is intra-arterial therapy?

Intra-arterial therapy (IAT) for acute ischemic stroke refers to endovascular catheter-based approaches to achieve recanalization using mechanical clot disruption, locally injected thrombolytic agents or both.

What is the maximum time for intra-arterial thrombolysis?

For these patients, IAT may be considered as an alternative to IV thrombolysis, although currently IV tPA is the only validated approach and its use is recommended to a maximum of 4.5 h from stroke onset [10].

How is thrombolytic therapy administered?

The “clot-busting” drug will be delivered through a peripheral intravenous (IV) line, usually through a visible vein in your arm. Performed at your bedside in an intensive care unit while your heart and lung functions are monitored. The drug circulates within the blood stream until it reaches the clot.

Which is an advantage of intra-arterial RTPA over intravenous RTPA administration?

However, recent experience with Intra-arterial (IA) infusion of rt-PA, alone or in combination with IV therapy or retrieval devices at the site of thrombus formation may provide a recanalization advantage over IV administration, especially in cases of high clot burden such as a thrombus located in the M1 or M2 segment …

What is intra-arterial thrombolysis stroke?

In IA thrombolysis, the cervicocephalic arterial tree is traversed with an endovascular microcatheter delivery system, the catheter port is positioned immediately within and adjacent to the offending thrombus, and fibrinolytic agents are infused directly into the clot.

What is intra-arterial RTPA?

Intra-arterial thrombolysis is an option for treatment of selected patients who can be treated within 3-6 hours after the onset of symptoms due to occlusion of the middle cerebral artery and who are not otherwise candidates for IV tPA.

What blood glucose level should trigger the administration of IV or subcutaneous insulin?

This evidence established new standards: initiate insulin therapy for persistent hyperglycemia greater than 180 mg/dL (10.0 mmol/L). Once insulin therapy is initiated, a glucose target of 140–180 mg/dL (7.8–10.0 mmol/L) is recommended for most critically ill patients (2).

Is thrombolysis a surgical procedure?

Thrombolysis is less invasive than conventional open surgery to remove clots and the hospital stay is relatively brief. Blood loss is less than with traditional surgical treatment and there is no obvious surgical incision. No surgical incision is necessary—only a small nick in the skin that does not need stitches.

How quickly does thrombolysis work?

For most people thrombolysis needs to be given within four and a half hours of your stroke symptoms starting. In some circumstances, your doctor may decide that it could still be of benefit within six hours. However, the more time that passes, the less effective thrombolysis will be.

What is intra-arterial thrombolysis?

What is intra-arterial route?

Intra-arterial (IA) chemotherapy is a form of regional delivery to brain tumors, designed to enhance the intra-tumoral concentrations of a given drug, in comparison to the intravenous route.

What is the meaning of thrombolysis?

Thrombolysis, also known as thrombolytic therapy, is a treatment to dissolve dangerous clots in blood vessels, improve blood flow, and prevent damage to tissues and organs.

What is intravenous thrombolysis?

Intravenous thrombolysis (IVT) is a standard treatment for both anterior circulation ischemic stroke (ACIS) and posterior circulation ischemic stroke (PCIS).

What is intra – arterial injection?

An intra-articular injection is a term used to describe a shot delivered directly into a joint with the primary aim of relieving pain. Corticosteroids (steroids) were the first substances used for this purpose. Other types of drug are now commonly used including local anesthetics, hyaluronic acid, and even Botox. 1 

What is intra arterial catheter?

Intra-arterial catheters (also called arterial cannulas or A-lines) are often inserted for invasive blood pressure (BP) monitoring and intravascular access for blood sampling in high-risk surgical and critically ill patients.
