Paper Abstract

Interstitial tumor therapy guided by imaging techniques is minimally invasive and a promising surgical approach which will become clinically practical only when effective, simple, and safe modalities for tumor excision and control of tumor vascular supply are available. In a novel experiment utilizing a 1.5 T magnetic resonance (MR) scanner, the carotid artery of a New Zealand white rabbit was identified and then clamped using the Premium Surgicliptm 9.0' disposable automatic clip applier. The magnetic resonance imager equipped with an angiography package was used to locate vasculature in the carotid triangle of the rabbit via fast scan techniques. The artery was then clamped with titanium clips, and repeat magnetic resonance angiography (MRA) clearly demonstrated the cessation of blood flow within the chosen vessel. The experimental results are promising, since the angiography package not only provided the visualization of the arterial vessel, but was also used to guide an MR compatible surgical instrument to the vessel, with no artifact seen.
