Mechanical Extraction

Persistent left superior vena cava, the most common thoracic venous anomaly, may complicate transvenous lead extraction (TLE). We report a successful case of TLE in a patient with persistent left superior vena cava, despite a long dwelling time and several pocket revisions due to pocket infection. The lead was removed via a hand-powered mechanical extraction sheath, and postoperative complications did not occur. Complicated TLE cases may have a better outcome if performed in a high-volume center with experienced specialists.

The described techniques for extraction of microfossils are directed primarily at the extraction of calcareous microfossils from various types of limestone, although the same techniques may beused for some sandstones and shales. The equipment needed is not complicated; the most obvious is a good binocular microscope with a working distance of three or more inches, to allow manipulation of the rock from which the specimens are to be extracted. The magnification required depends on the size of the specimens, but should go up to at least 80x. Other essential tools are a pin vise with a chuck which will hold an ordinary steel sewing needle and a rotary dental machine or other grinding device which will accept a small thin carborundum wheel. The latter is useful for sharpening needles as well as for cutting specimens out of the rock. An additional useful item is a percussive device such as a mechanical engraver fitted with a chuck which will hold an old fashioned steel phonograph needle. This instrument is described in detail by Palmer (this volume, chapter 20). A dish of water and a fine (00000) camel's hairbrush are necessary to move the specimens, once freed, to a slide or other receptacle. A rock trimmer is useful for reducing large blocks of fossiliferous rock into pieces that can be handled under the microscope, although with some collections this can be done with a hammer and cold chisel. Some paleontologists prefer to crush their samples and then pick through the chips to find specimens; however, this technique tends to break spines and frills from highly ornamented forms and is not recommended unless the microfauna is known to consist mostly of smooth species. Most of the equipment mentioned above can be found in catalogs such as that of the Edmund Scientific Co., 101 E. Gloucester Pike, Barrington, N.J. 08007.

Life Threatening

Prior to the introduction of successful intravascular countertraction techniques, options for lead extraction were limited and dedicated tools were non-existent. The significant morbidity and mortality associated with these early extraction techniques limited their application to life-threatening situations such as infection and sepsis. The past 30 years have witnessed significant advances in lead extraction technology, resulting in safer and more efficacious techniques and tools. This evolution occurred out of necessity, similar to the pressure of natural selection weeding out the ineffective and highly morbid techniques while fostering the development of safe, successful and more simple methods. Future developments in lead extraction are likely to focus on new tools that will allow us to provide comprehensive device management and the design of new leads conceived to facilitate future extraction. With the development of these new methods and novel tools, the technique of lead extraction will continue to require operators that are well versed in several methods of extraction. Garnering new skills while remembering the lessons of the past will enable extraction technologies to advance without repeating previous mistakes.

Cardiac Surgeon

Abstract Background The guidelines suggest close co-operation between TLE operating team and cardiac surgery and its key role in the management of life-threatening complications remains unquestionable. But the role of cardiac surgeon seems to be much more extended. Purpose We have analysed the role of cardiac surgery in treatment of patients undergoing TLE procedures. Methods Using standard non-powered mechanical systems we have extracted ingrown PM/ICD leads from 3207 pts (38,7% female, average age 65,7-y) during the last 14 years. Non-infectious TLE indications were in 66,4% of patients. 46% had PM DDD system, 19% PM SSI, 22% ICD, 9% CRT, 4% other systems. In 12% of patients abandoned leads were found. 8% of patients had one lead, 54% - two, 15% - three and 4% - 4–6 leads in the heart. An average dwell time of all leads was 91,5 mth. The lead entry side was left in 96% of patients, right in 3% and both – 4%. Results Procedural success 96,1%, clinical success - 97,8%, procedure-related death 0,2%. Major complications appeared in 1,9% (cardiac tamponade 1,2%, haemothorax 0,2%, tricuspid valve damage 0,3%, stroke, pulmonary embolism <1%). Conclusions Rescue cardiac surgery (for severe haemorrhagic complications) is still the most frequent reason of surgical intervention (1,1%). The second area of co-operation includes supplementary cardiac surgery after (incomplete) TLE (0,8%). The third one is connected with reconstruction or replacement of tricuspid valve, which can be affected by ingrown lead or damaged during TLE procedure (0,5%). Implantation of the complete epicardial system during any surgical intervention (rescue or delayed) should be considered as a supplementation of the operation (0,65%). Some of patients after TLE need implantation of epicardial leads for permanent epicardial pacing (0,6%) and some only left ventricular lead to rebuild permanent cardiac resynchronisation (0,5%). The single experience of large TLE centre indicates the necessity of close co-operation with cardiac surgeon, whose role seems to be more comprehensive than a surgical stand-by itself.
