Comparative StudyUS-guided femoral and sciatic nerve blocks for analgesia during endovenous laser ablation.
Endovenous laser ablation may be associated with significant pain when performed under standard local tumescent anesthesia. The purpose of this study was to investigate the efficacy of femoral and sciatic nerve blocks for analgesia during endovenous ablation in patients with lower extremity venous insufficiency. ⋯ Ultrasound-guided femoral and sciatic nerve blocks may provide considerable reduction of pain during endovenous laser and other treatments, such as ambulatory phlebectomy and foam sclerotherapy. They may make these procedures more comfortable for the patient and easier for the operator.

Clinical outcome and safety of multilevel vertebroplasty: clinical experience and results.
To compare safety and efficacy of percutaneous vertebroplasty (PVP) when treating up to three vertebrae or more than three vertebrae per session. ⋯ PVP is an efficient and safe technique for symptomatic vertebral fractures independently of the vertebrae number treated per session.

Case ReportsRuptured aortic aneurysm from late type II endoleak treated by transarterial embolization.
Endoleak is the most common complication after endovascular aneurysm repair. The most common type of endoleak, a type II endoleak, typically follows a benign course and is only treated when associated with increasing aneurysm size. In this case report, we describe a ruptured abdominal aortic aneurysm due to a late, type II endoleak occurring 10 years after endovascular aneurysm repair that was successfully treated by transarterial embolization.

Comparative StudyHybrid repair of complex thoracic aortic arch pathology: long-term outcomes of extra-anatomic bypass grafting of the supra-aortic trunk.
Hybrid repair constitutes supra-aortic debranching before thoracic endovascular aortic repair (TEVAR). It offers improved short-term outcome compared with open surgery; however, longer-term studies are required to assess patient outcomes and patency of the extra-anatomic bypass grafts. ⋯ Hybrid operations to treat aortic arch disease can be performed with results comparable to open surgery. The longer-term outcomes demonstrate low rates of reintervention and high rates of graft patency.

Patency of femoral tunneled hemodialysis catheters and factors predictive of patency failure.
To determine the patency rates of and factors associated with increased risk of patency failure in patients with femoral vein tunneled hemodialysis catheters. ⋯ Patients who were of a more advanced age and had diabetes were at greater risk of femoral catheter failure, whereas those who received femoral catheters from the right side were less at risk of catheter failure.
