[Gastrostomy tubes inserted with radiologic techniques].

Radiologic techniques can be used for patients in need of long-term enteral nutritional support. In particular, these techniques can provide solutions when endoscopic techniques cannot be performed. Percutaneous radiologic gastrostomy is an alternative to percutaneous endoscopic gastrostomy. Percutaneous radiologic transgastric jejunostomy should be reserved for patients with proven gastroesophageal reflux. When both are not possible, percutaneous radiologic jejunostomy is indicated. Percutaneous radiologic gastrostomy and percutaneous radiologic transgastric jejunostomy have a high technical success rate (> or = 91-95%). The success rate of percutaneous radiologic jejunostomy is lower (85-88%). With radiologic techniques, major complications occur in 0.5-13% of cases. The percentage of complications for percutaneous radiologic gastrostomy and percutaneous radiologic transgastric jejunostomy are lower than those for percutaneous radiologic jejunostomy. The less serious, mostly late-onset complications (2.9-13%) are usually easy to treat. Radiologic techniques have a higher initial success rate but more late-onset complications than endoscopic techniques.

Gamma radiation induces positive vascular remodeling after balloon angioplasty: a prospective, randomized intravascular ultrasound scan study.

BACKGROUND: Endovascular brachytherapy (EBT) has been shown to prevent restenosis after percutaneous transluminal coronary angioplasty (PTA) in both animal and clinical studies. However, as yet, the effect of EBT on peripheral arteries is unknown. OBJECTIVE: This intravascular ultrasound scan (IVUS) study evaluates the effect of EBT on the extent of plaque growth and vascular remodeling after PTA of the femoropopliteal artery. METHODS: Twenty-four patients with obstructive disease of the femoropopliteal artery underwent standard PTA. Patients were randomized to receive no additional therapy or additional EBT (192-Iridium) after PTA. IVUS investigation was performed after PTA and at 6-month follow-up. A comparison was made between patients without EBT (n = 16) and with EBT (n = 8) in the change in lumen, vessel, and plaque area and plaque dissections seen with IVUS at 6-month follow-up. RESULTS: At follow-up, IVUS revealed a significant difference in lumen area change between patients without and with EBT (-9% and +23%, respectively; P =.03). This difference was the result of a significant difference in vessel area change (+2% and +19%, respectively; P =.05). In both groups of patients, a similar increase in plaque area (+12% and +16%, respectively; P =.80) was encountered. Plaque dissections encountered immediately after PTA were absent at follow-up in patients without EBT, whereas in four of the eight patients with EBT, a persistent dissection was encountered. CONCLUSION: This randomized IVUS study showed that gamma-radiation after PTA has a positive effect on lumen dimensions at 6-month follow-up by inducing positive vascular remodeling (ie, vascular dilatation); gamma-radiation seemed not to affect plaque growth. In addition, gamma-radiation has an effect on the healing process of dissections after PTA.
