High Intensity Focussed Ultrasound Therapy for Prostatic Tumors: Anaesthesiologists Perspective

High Intensity Focussed Ultrasound Therapy for Prostatic Tumors: Anaesthesiologists Perspective

Ultrasound guided epidural anaesthesia, regional blocks, internal jugular vein cannulations, ultrasound lithotripsy and ultrasound assisted thrombolytsis are some of the current medical applications of ultrasound technology [1,2]. Low-intensity ultrasound produces physiological effects such as stimulation of bone-growth, and has the potential to temporarily disrupt the blood-brain barrier for d...

High-intensity focussed ultrasound (HIFU) treatment in uraemic secondary hyperparathyroidism

BACKGROUND The recently developed non-invasive high-intensity focussed ultrasound (HIFU) technique for the destruction of parathyroid adenomas could also be of interest for the treatment of secondary hyperparathyroidism (SHP) in patients with chronic kidney disease (CKD). We conducted a pilot study using this method. METHODS Five chronic haemodialysis patients with severe SHP underwent one to...

Optimizing Ultrasonic Intensity for High Intensity Focused Ultrasound Therapy

High-intensity focused ultrasound in the treatment of prostatic tissue.

OBJECTIVE Beginning in 1987, high-intensity focused ultrasound was investigated in the canine model to determine the feasibility of destroying prostate tissue. After demonstrating the ability to ablate prostate tissue reliably in a canine model, a 15-patient pilot clinical study was undertaken at Indiana University in the fall of 1992. This pilot study was undertaken to assess the safety in the...

Effects of High-Intensity Ultrasound on Prostatic In Vivo

High-intensity ultrasound has been used to treat Dunning R3327 prostatic adenocarcinoma implanted s.c. in Fischer Copenhagen rats. Focused ultrasound was generated with a 1-MHz transducer and energy was provided by a 7.5-kW power amplifier. Seventy-four rats were treated using two different sublines of Dunning tumor. Study 1 dealt with 49 rats with the Mat-Ly-Lu subline, treated with acoustic i...
