1/10. Removal of infected pacemaker leads with deep hypothermic circulatory arrest and open surgical exploration of the superior vena cava and innominate veins.Despite the use of transvenous methods for extraction of infected leads, failed attempts may result in retained lead fragments. Retained lead fragments may be a focus of continued infection leading to sepsis. We present two patients in which conversion from cardiopulmonary bypass to hypothermic circulatory arrest allowed direct visualization, using venotomies in the superior vena cava and innominate vein to achieve complete removal of retained pacemaker lead fragments. Use of venotomies in the extracardiac venous system is a technical addition to prior descriptions of lead extraction using deep hypothermia and circulatory arrest.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/10. haemophilus parainfluenzae complicating total hip arthroplasty: a rapid failure.We present a case of rapid failure of a total hip arthroplasty caused by infection with haemophilus parainfluenzae. The septic loosening occurred over a period of 3 months and followed a dental extraction that had not been covered by prophylactic antibiotics. This failure occurred in a previously well-functioning and asymptomatic prosthetic joint.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
3/10. Surgical extraction of infected pacemaker leads after cardiac surgery.Surgical extraction of permanent pacemaker leads is performed when noninvasive extraction is felt to be unsafe or has been unsuccessfully attempted. Surgical extraction in patients with previous cardiac surgery presents a particular challenge as re-sternotomy is hazardous and the presence of surgical adhesions makes video-assisted approaches difficult. We report 2 cases of successful deployment of a surgical technique using femorofemoral cardiopulmonary bypass and right anterior thoracotomy for removal of pacemaker leads.- - - - - - - - - - ranking = 3.5keywords = extraction (Clic here for more details about this article) |
4/10. infection of a total hip arthroplasty with prevotella loeschii.infection is a serious complication of total hip replacement. It has been proposed that 6% of all infections after total hip arthroplasty may be of dental origin through hematogenous spread. However, no conclusive evidence that the mouth is a definitive source for infection of a total hip replacement has been reported. In the current case, prevotella loeschii, a pigmented bacteroides species was identified in a total hip replacement. prevotella loeschii is an organism which exclusively inhabits the dental region. Hematogenous spread of prevotella loeschii may occur after penetration of the mucosal barrier in cases of endodontic or periodontic lesions, pericoronitis, or complications of tooth extraction. The involvement of prevotella loescheii in an infection in a patient who had a total hip arthroplasty is strong evidence for the mechanism of a hematogenous infection from a dental source.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
5/10. Intrapelvic extraction of a total hip prosthesis. A case report.A 69-year-old man with a total hip prosthesis, recurrent infection, and intrapelvic incarceration of the acetabular components required extraction of a long-stem total hip prosthesis through three incisions. Retroperitoneal intrapelvic extraction of the incarcerated prosthesis was necessary. This approach allowed removal of intrapelvically migrated components and the eradication of the infection. The patient had no signs of infection five years postoperatively.- - - - - - - - - - ranking = 3keywords = extraction (Clic here for more details about this article) |
6/10. Previously unreported complication of trephine reamers in revision total hip arthroplasty.Trephine reamers have been used in revision total hip arthroplasty to facilitate the removal of femoral prostheses without creating additional osteotomy sites. These reamers are available in graduated sizes so as to minimize bone loss. We present a complication not previously reported in the literature. While performing the extraction of a well-fixed femoral prosthesis, the trephine reamer broke at its distal end, expanded, and created a cortical defect distal to the prosthesis.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
7/10. Superior vena cava thrombosis after intravascular AICD lead extraction: a case report.Pacemaker lead extraction has been shown to be an effective and safe treatment in the case of infected per-manent pacemaker leads. However, it can lead to potentially serious complications, usually occurring during the ex-traction procedure. This report describes a case of a 74-year-old male with a persistent superior vena cava thrombo-sis related to an infected permanent pacemaker lead transvenous extraction. Clinical and surgical management are discussed.- - - - - - - - - - ranking = 3keywords = extraction (Clic here for more details about this article) |
8/10. Successful laser-assisted removal of an infected ICD lead with a large vegetation.Infective endocarditis involving transvenous pacing leads is an uncommon but potentially lethal complication of implantable cardioverter-defibrillator (ICD) implantation. Complete removal of the device and the leads is presently considered to be the optimal treatment in such patients and laser-assisted lead removal is an effective and safe nonthoracotomy approach. However, large vegetations (>10 mm) attached to the lead limit nonthoracotomy explantation because of the potential for hemodynamically embarrassing pulmonary embolization. Laser extraction of leads with vegetation area >300 mm2 has rarely been reported. In this case report, we describe a patient with an infected ICD lead with vegetation greater than 41 x 12.5 mm (512 mm2) in size that was explanted with laser-assistance. The resulting pulmonary embolus produced a 33 x 20 mm pulmonary infarction without hemodynamic or respiratory compromise.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
9/10. Postoperative endophthalmitis resulting from prosthesis contamination in a monocular patient.Monocular patients who wear an ocular prosthesis may harbor pathogenic conjunctival flora both in the socket and in the contralateral eye. They may therefore be at increased risk of developing endophthalmitis after intraocular procedures. We studied a monocular, prosthesis-wearing, 86-year-old man who underwent cataract extraction, subtotal transpupillary vitrectomy, and intraocular lens insertion. Fulminant endophthalmitis ensued postoperatively, and despite complete vitrectomy and administration of intraocular antibiotics, the eye lost light perception. Intravitreal as well as conjunctival cultures bilaterally grew proteus mirabilis. The patient disclosed that he cleaned the prosthesis frequently because of discharge. We considered an association between this bacterial colonization and the risk of developing postoperative endophthalmitis and suggest prophylactic measures for treatment of monocular patients undergoing intraocular procedures.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
10/10. Localized osteomyelitis secondary to endodontic-implant pathosis. A case report.This case report documents the placement of a single implant fixture in an incisor extraction socket, with the adjacent lateral incisor developing periapical pathosis within 2 weeks. This root-end inflammatory process proceeded to communicate with the surface of the implant fixture. Although endodontic therapy was performed within one week on the devitalized tooth, and extensive osteomyelitis developed around the implant. Three weeks after placement, the fixture had to be removed. The osteotomy site appeared to be healing uneventfully during the one month follow-up period. Seven possible causes for this occurrence are discussed.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
