Extraction of Lead by Direct Electrolysis of Lead Sulfide

Unusual embolization of a pacemaker lead fragment during lead extraction

In 2014, an 84-year-old man with pacemaker erosion was referred to our center. He underwent coronary artery bypass graft surgery in 2008 for multivessel coronary artery disease. In 2009, he developed sick sinus syndrome and received a Biotronik Cylos 990 DR-T DDD pacemaker with a 7.2-F Biotronik Selox SR 53 active fixation atrial lead and a 4.8-F Sorin Xfine TX26D passive ventricular lead. In J...

Lead Zinc Extraction Processes

Zinc and lead are the two most widely used non-ferrous metals after aluminium and copper as vital materials in everyday life. They are mined and smelted in many countries in both the developed and developing world. Both pyrometallurgical as well as hydrometallurgical methods are used for production of lead zinc depending on the type of raw material used as a charge. In the pyrometallurgical pro...

Substrate Effects on the Structural Properties of Thin Films of Lead Sulfide

Nanocrystalline PbS thin films are deposited on glass and alumina substratesthrough the chemical bath deposition technique by creating similar conditions, in orderto investigate the effects of the substrate. The structural and optical properties of PbSfilms are investigated by X-ray diffraction, scanning electron microscope, and UV–Vis.The structural analyses of the films indicate that they are...

Reuse of Occluded Veins During Permanent Pacemaker Lead Extraction: A New Indication for Femoral Lead Extraction

OBJECTIVES This study examined the utility of a novel technique for reuse of thrombosed veins when extracting permanent pacemaker leads via a femoral vein approach. BACKGROUND Although lead extraction permanent pacemaker using a femoral approach has advantages over the subclavian approach, it cannot be used to provide access for a new lead using currently employed techniques. This is importan...
