Empyema and effusion: outcome of image-guided small-bore catheter drainage.
Empyema and complicated pleural effusion represent common medical problems. Current treatment options are multiple. The purpose of this study was to access the outcome of image-guided, small-bore catheter drainage of empyema and effusion. ⋯ All treatment failures, requiring surgery, occurred in the empyema group (19%; n = 12; p < 0.05). In conclusion, noninfected pleural collections are adequately treated with small-bore catheters, however, empyemas have a failure rate of 19%. The threshold for using urokinase and larger-bore catheters should be low in empyema.

Case ReportsPercutaneous pediculoplasty for vertebral hemangioma involving the neural arch: a case report.
Vertebral hemangiomas occasionally involve the neural arch and they can be symptomatic. We report a case of symptomatic vertebral hemangioma mainly involving the unilateral neural arch which was successfully treated with percutaneous pediculoplasty using a single-needle technique.

We present the case of a rare entity which is a complication of a disease process that had almost disappeared from the Western World. With the recent resurgence in reported cases of Mycobacterium tuberculosis (TB) in Western communities, it is important to recognize complications and sequelae. ⋯ Multidetector computed tomography angiography diagnosed a Rasmussen's aneurysm, confirmed by digital subtraction angiography and then successfully embolized with glue. We outline this rare case and the embolization technique and review previously documented reports.

Multicenter StudyPrimary cutting balloon angioplasty for treatment of venous stenoses in native hemodialysis fistulas: long-term results from three centers.
To evaluate the technical success and patency rates following primary cutting balloon angioplasty for venous stenoses in native dialysis fistulas. ⋯ PCB angioplasty has high technical success and low complication rates. The long-term patency rates are favorable for PCB angioplasty and compare favorably with other series.

Case ReportsEmergency stenting of a ruptured infected anastomotic femoral pseudoaneurysm.
A 74-year-old man presented with a ruptured infected anastomotic femoral pseudoaneurysm. Due to severe medical comorbidities he was considered unsuitable for conventional surgical management and underwent an emergency endovascular repair with a balloon-expandable covered stent. ⋯ To our knowledge, emergency endovascular treatment of a free ruptured bleeding femoral artery pseudoaneurysm has not been documented before in the English literature. This case illustrates that endovascular therapy may be a safe and efficient alternative in the emergent management of ruptured infected anastomotic femoral artery pseudoaneurysms when traditional open surgery is contraindicated.
