Adventitial Cystic Disease of the Popliteal Artery Contributing to Supera Stent Fracture.

A 60-year-old male presented with complaints of a non-healing wound on his right shin. Initial angiography showed a 100% occlusion of the right superficial femoral artery thought to be thrombotic in nature; he was treated with percutaneous transluminal angioplasty and stenting. Three weeks later, he presented with continuing symptoms of claudication.

A novel non-vascular system to treat resistant hypertension.

Aims: To evaluate in a preclinical model the utility of a monopolar electrode catheter delivering radiofrequency (RF) energy placed into the renal pelvis in order to treat resistant hypertension (RH).

Methods And Results: Sixteen female domestic swine weighing 60-65 kg underwent renal pelvic denervation via ureteral access. Three animals were euthanised immediately after delivery of RF energy; five animals were allowed to survive for seven days, six animals were allowed to survive for 14 days and two animals were allowed to survive for 30 days.
