Percutaneous Cricothyrotomy

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A surgical airway procedure is indicated when other forms of endotracheal intubation have failed and ventilation is worsening or not possible. This is the feared "can't intubate, can't ventilate" scenario, and in the emergency setting, cricothyrotomy is the surgical procedure of choice. Cricothyrotomy is preferred over tracheotomy because of the lower risk of complications, the predictable anatomy...

A thermal tumor ablation procedure is described. The entire procedure is detailed, including pretreatment planning and imaging studies, anesthesia, adjuvant techniques to facilitate a percutaneous approach, imaging guidance of the ablation device to the tumor, thermal treatment, post-treatment care and follow-up.

We present a protocol to assess changes in neuromuscular function. Percutaneous electrical nerve stimulation is a non-invasive method that evokes muscular responses. Electrophysiological and mechanical properties of these responses permit the evaluation of neuromuscular function from brain to muscle (supra-spinal, spinal and peripheral levels).

Pulmonary vein isolation (PVI) with an ablation catheter is a curative treatment for atrial fibrillation (AF). Robotic catheter systems aim to improve catheter steerability. Here, a procedure with a new robotic catheter system is presented. The goal of the procedure is electrical block between pulmonary vein and left atrium.

Source: Muto, A., et al. Ablation of a Neuronal Population Using a Two-photon Laser and Its Assessment Using Calcium Imaging and Behavioral Recording in Zebrafish Larvae. J. Vis. Exp. (2018) In this video, a two-photon laser ablation procedure is demonstrated, enabling the selective destruction of fluorescent neurons in agarose-immobilized zebrafish larvae. High-resolution imaging before and after the procedure confirms efficient neuronal damage, as observed by the absence of fluorescence.
FAQs
Radiofrequency and microwave probes heat targeted tissue, while cryothermal systems freeze it. Other energy forms can electrically disrupt cells and their function. These mechanisms give clinicians different ways to destroy abnormal tissue, with the selected modality depending on the treatment goal and the characteristics of the target. The result is focused tissue destruction without relying on open surgical access.
The energy type determines how the targeted tissue is affected: heating, freezing, or electrical disruption produces different cellular consequences. Because treatment goals vary between lesions and organs, selecting an appropriate modality helps align the physical effect with the intended outcome. This flexibility supports use in both tumor treatment and cardiac procedures, although the target and purpose differ.
In interventional oncology, the target is a selected tumor or other diseased lesion that needs tissue destruction. In cardiac electrophysiology, the target is tissue responsible for an abnormal rhythm, and treatment aims to eliminate that rhythm-generating function. Thus, the same broad approach serves different medical purposes: lesion control in one setting and correction of electrical activity in another.
The procedure begins by placing a needle or catheter through the skin toward the abnormal tissue. Image-guided equipment helps position the probe at the intended target, after which radiofrequency, microwave, cryothermal, or another energy source is delivered. The energy is selected to heat, freeze, or electrically disrupt the targeted cells, depending on the treatment objective.
Image guidance helps direct the needle, catheter, or probe toward the intended lesion or tissue region. This supports precise delivery of energy to an abnormal target while limiting the need for open surgical exposure. In medicine, that precision is important because the procedure is designed to destroy selected tissue and can therefore reduce procedural trauma compared with conventional surgery.
Clinicians may consider it when a selected tumor or abnormal cardiac tissue can be reached through a needle or catheter and treated with focused energy. The approach can serve as an alternative or complement to conventional surgery. Its minimally invasive access may shorten recovery and reduce procedural trauma, making it relevant when targeted tissue destruction is the primary treatment goal.
