  Computerized tomography -- guided percutaneous bilateral selective cordotomy
Percutaneous bilateral cordotomy performed using conventional techniques may cause the patient to develop sleep-induced apnea due to bilateral destruction of the ventrolateral reticulospinal tract.
Computerized tomography­guided percutaneous bilateral selective cordotomy may prove to be the treatment of choice for patients suffering from bilateral cancer pain, because of the advantages of higher segmental selectivity and controlled ablation of neural structures at a higher cervical level under direct visualization.
The target in percutaneous cordotomy is the lateral spinothalamic tract in the anterolateral part of the spinal cord at the C1­2 level, although the posterolateral part of the lateral spinothalamic tract should be targeted to control pain from the lower trunk and extremities, as is done in bilateral procedures.

 Percutaneous - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-22)
In surgery, percutaneous pertains to any medical procedure where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an "open" approach where inner organs or tissue are exposed (typically with the use of a scalpel).
The percutaneous approach is commonly used in vascular procedures.
This involves a needle catheter getting access to a blood vessel, followed by the introduction of a wire through the lumen of the needle.

 Role of Percutaneous Endoscopic Gastrostomy (PEG)
The purpose of this statement is to provide a current, practical basis for the use of percutaneous endoscopic gastrostomy (PEG) in patients who require long-term enteral feeding but are unable to maintain sufficient oral intake.
Finally, percutaneous gastrostomy has also been described without endoscopy using a nasogastric tube or gastric insufflation, fluoroscopic monitoring, and a direct percutaneous catheter insertion technique(12).
The basic elements common to all of these techniques are: (1) gastric insufflation to bring the stomach into apposition to the abdominal wall; (2) percutaneous placement of a tapered cannula into the stomach; (3) passage of a suture or guidewire into the stomach; (4) placement of the gastostomy tube; and verification of the proper position(1-3,10-12).

The percutaneous tracheostomy is a minimally invasive, effective and reliable procedure and has become the alternative to surgical tracheostomy [1].

As experience with percutaneous tracheostomy increases, the number of complications will decrease, even if another technique is used, although in our study this might well have been balanced by the fact that over time more fellows performed the procedure.

 DISC Nucleoplasty Percutaneous Discectomy
Patients who can benefit from percutaneous disc decompression or 'percutaneous discectomy' as it is called, are those with pain arising from a contained herniated disc - that is a bulging disc where there is no rupture in the outer wall.
The reason that DISC Nucleoplasty is such a significant advance in percutaneous discectomy is its use of Coblation.
By overcoming the limitations of prior methods of percutaneous discectomy, DISC Nucleoplasty has demonstrated the potential to produce equivalent, or even better, outcomes in a procedure that is simpler, quicker, and less traumatic and has faster recovery-times.
