Most procedures are either outpatient or require an overnight stay in the hospital with minimal recovery time. For patients with pain from skeletal metastases, relief can often be obtained either by ablation or vertebroplasty, where stabilizing cement is injected under careful fluoroscopic guidance.
In some patients, these two percutaneous interventions may be combined. Ablation modalities can generate heat by delivering microwave or radiofrequency energy or cold via cryoablation. Some patient groups may also be too weak to undergo open surgery. Tumours can intrude into various ducts and blood vessels of the body, obstructing the vital passage of food, blood or waste. For this reason practitioners must have attained solid training in radiation protection.
Hence, most treatments are nowadays offered as day case or outpatient appointments and patients may enjoy rapid recovery and minimal pain and discomfort with low rates of complications. For patients who may be candidates for curative liver surgery, but would have insufficient remnant liver tissue left remaining, portal vein embolization can be useful. Vacuum assisted breast biopsy may provide a high diagnostic yield in case of breast tumours. Cryoablation can also be used for patients with post-thoracotomy pain.
Tumors within the liver are supplied by the hepatic artery. This is done with the intent of inducing growth in the contralateral hepatic lobe, not dissimilarly from portal vein embolization.
The minimally invasive nature of the treatments means they cause less pain, fewer side effects and shorter recovery times. Both ablation and embolization techniques are minimally invasive treatment, i.
