Insights

Direct Transfer to the Angiography Suite (DTAS) streamlines care for large vessel occlusion (LVO) stroke patients. This strategy bypasses the emergency department to expedite diagnosis and reperfusion therapy, significantly reducing treatment times.

Area of Science:

  • Neurology
  • Interventional Radiology
  • Stroke Medicine

Background:

  • Large vessel occlusion (LVO) stroke requires rapid endovascular therapy for optimal outcomes.
  • Conventional hospital workflows often cause delays in diagnosis and treatment initiation.
  • Expediting reperfusion is crucial for improving patient prognosis in acute ischemic stroke.

Purpose of the Study:

  • To present a guideline on the Direct Transfer to the Angiography Suite (DTAS) strategy for LVO stroke.
  • To outline the infrastructure, workflow, and quality control for DTAS implementation.
  • To support timely reperfusion therapy in acute ischemic stroke patients.

Main Methods:

  • Systematic review of international and domestic studies on DTAS.
  • Expert panel consensus development by the Chinese Stroke Association.
  • Delineation of diagnostic and therapeutic workflows using advanced imaging and angiography.

Main Results:

  • DTAS facilitates rapid diagnosis and prompt reperfusion therapy for LVO stroke.
  • The DTAS workflow significantly reduces door-to-reperfusion time compared to conventional methods.
  • Implementation requires specific infrastructure and adherence to defined quality indicators.

Conclusions:

  • DTAS is an effective emerging strategy to improve outcomes in LVO stroke.
  • Standardized DTAS protocols are essential for efficient and safe patient care.
  • This guideline provides a framework for adopting DTAS in clinical practice.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
