Learning curve during percutaneous treatment of carotid lesions

Ultrasound findings during percutaneous treatment of bifurcated coronary lesions.

INTRODUCTION AND OBJECTIVES Provisional stenting has been shown to be effective in the treatment of bifurcated coronary lesions. The aim of this study was to evaluate changes in the geometry of the main vessel stent following side branch (SB) dilatation and kissing balloon (KB) inflation. METHODS The study involved 23 patients with a bifurcated coronary lesion. A first intravascular ultrasoun...

The learning curve in the training of percutaneous nephrolithotomy.

OBJECTIVES To investigate the learning curve in the training of percutaneous nephrolithotomy (PCNL). METHODS A total of 104 PCNL cases were included in this evaluation to define the learning curve of a surgeon with no previous experience at performing solo PCNL. Two parameters of expertise were reviewed, namely the operation and fluoroscopic screening times. The operation time was calculated ...

Training in percutaneous nephrolithotomy: The learning curve and options

OBJECTIVE To review the current approach to training and the learning curve for percutaneous nephrolithotomy (PCNL), and to formulate a recommendation for structured PCNL training for the urologist in-training. METHODS Publications related to PCNL training, simulator training, surgical training and working-hour restrictions on surgical training were reviewed. RESULTS The key components for ...

Distal protection devices during percutaneous coronary and carotid interventions

Distal embolization of particulate matter complicates percutaneous coronary and peripheral interventions more often than had been recognized until recently. A number of distal protection devices are under development. The PercuSurge GuardWiretrade mark is a balloon occlusion thrombectomy device approved by the United States Food and Drug Administration for saphenous vein graft intervention. A n...
