Case ReportsEndovascular treatment of extracranial internal carotid aneurysms using endografts.
Aneurysms of the extracranial internal carotid artery (EICA) are infrequent. They are difficult to treat with conventional surgery because of their distal extension into the skull base. We report three cases of EICA aneurysms in two symptomatic patients successfully treated with polytetrafluoroethylene self-expanding endografts using an endovascular approach. The aneurysms were located distal to the carotid bifurcation and extended to the subpetrous portion of the internal carotid artery.

Frequency and risk factors of various complications after computed tomography-guided radiofrequency ablation of lung tumors.
To retrospectively determine the frequency and risk factors of various side effects and complications after percutaneous computed tomography-guided radiofrequency (RF) ablation of lung tumors. ⋯ The total complication rate for all treatment sessions was 58%, and 25% of patients did not have any complications after RF ablation. Although major complications can occur, RF ablation of lung tumors can be considered a safe and minimally invasive procedure.

Case ReportsAir embolism detected during computed tomography fluoroscopically guided transthoracic needle biopsy.
Air embolism is a rare but potentially fatal complication of percutaneous needle biopsy of the lung. We report a case of cerebral air embolism which occurred during computed tomography (CT)-guided needle biopsy. Air entering the aorta is depicted on CT-fluoroscopy images of the procedure.

Long-term follow-up after endovascular treatment of acute aortic emergencies.
To investigate the long-term outcome and efficacy of emergency treatment of acute aortic diseases with endovascular stent-grafts. ⋯ Endovascular treatment is safe and effective for emergency treatment of life-threatening acute thoracic aortic syndromes. Results are encouraging, particularly for traumatic aortic ruptures. However, regular follow-up is mandatory, particularly in the other pathologies, to identify late complications of the stent-graft and to perform appropriate additional corrections as required.

Randomized Controlled TrialDoes prebiopsy, nonsterile ultrasonography gel affect biopsy-site asepsis?
The purpose of this study was to determine the extent to which the use of nonsterile gel, prior to antiseptic procedures in ultrasonography (US)-guided percutaneous biopsies, results in contamination of the biopsy site. ⋯ We conclude that nonsterile gel used prior to percutaneous biopsy does not affect biopsy-site asepsis.
