1/58. Safe removal of massive intrapelvic cement using ultrasonic instruments.The extraction of massive intrapelvic deposits of cement in revision total hip arthroplasty presents the surgeon with a philosophical dilemma and a technical challenge. The cement is difficult to remove because of the disparity between the size of the cement mass and the defect in the acetabulum. In addition, the cement mass lies close to major intrapelvic organs, and the use of force applied with sharp cement-removing instruments poses a danger to these structures. We report on the ultrasonic technique of cement removal used to extract a massive intrapelvic cement deposit safely.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |

3/58. Retrieval of distally migrated, impacted biliary endoprostheses using a novel guidewire/basket "lasso" technique.BACKGROUND: Migration of biliary endoprostheses is a recognized complication of bile duct stenting. Removing a stent that has migrated is usually straightforward, but this can be challenging when the stent is firmly impacted in the opposite wall of the duodenum or within a diverticulum. We describe a new technique for removing such impacted stents using a guidewire/basket lasso. methods: To perform the lasso technique, a retrieval basket and a guidewire are passed side-by-side through the accessory channel of the duodenoscope. The basket catheter is advanced underneath the stent and the guidewire manipulated over the stent; the basket is opened and the guidewire advanced through it. Closure of the basket creates a loop around the stent that can then be removed using gentle traction. RESULTS: The lasso technique was successfully used in three cases where other maneuvers failed. CONCLUSIONS: Biliary endoscopists should find this technique useful for retrieval of distally migrated biliary stents that are impacted against mucosa or the wall of a diverticulum so as to prevent standard basket extraction.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/58. Posterior chamber intraocular lens dislocation with the bag.We report a rare case of a 46-year-old man presenting with a luxation of a posterior chamber intraocular lens (IOL) with the capsular bag after ocular contusion. Preoperative axial length was 36.58 mm. After trauma, pars plana extraction of the dislocated IOL inside the capsular bag was performed using a forceps. Capsular fibrosis had probably weakened the zonules, which were ruptured by the trauma. This observation confirms the necessity of a large continuous curvilinear capsulotomy and meticulous cleaning of the anterior and posterior capsules to minimize postsurgical fibrosis and capsule contraction.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/58. Percutaneous extraction of an abandoned coiled pacing lead.Abandoning redundant pacing leads has been an accepted practice in most cases. Late migration of a lead is a rare, unpredictable, and potentially lethal complication of this approach and requires immediate removal. We report the case of an atrial pacing lead that had migrated and was found coiled in the right atrium. It was removed by a snare catheter via a femoral approach.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
6/58. A complication of pectus excavatum operation: endomyocardial steel strut.An 18-year-old patient who had correction of pectus excavatum deformity in our department 4 years earlier was admitted because of stabbing chest pain. He had not attended to postoperative controls and had not come for extraction of the steel strut, although he had been contacted. He was diagnosed to have a broken steel strut, and the strut was noted to be embedded in the myocardium. This unreported complication of pectus excavatum operation forced us to review sternal support techniques.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/58. Intrapulmonary artery and intrabronchial migration and extraction of a fragment of J-shaped atrial pacing catheter.A fragment of a fractured Telectronics Atrial Accufix 330-801 lead asymptomatically perforated the adjacent bronchus and was detected on routine chest X-ray. The metallic fragment was located by chest CT scan and bronchial fluoroscopy to lie between the right lobar bronchus and the pulmonary artery, confirming bronchial perforation. The foreign body was removed without complication by direct visualisation with rigid bronchoscopy.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
8/58. Recurrent cardioembolic stroke related to late dislodgement of a right atrial pacing lead into the left atrium.A 76-year-old woman had a permanent transvenous DDDR pacemaker implanted for complete atrioventricular block. She was hospitalized 4 years later for recurrent transient ischaemic attacks related to dislodgment of the atrial lead into the left atrium through a patent foramen ovale. The patient was successfuly treated by transvenous extraction of the atrial lead. The follow-up has been uneventful 12 months after the procedure. Left atrially dislodged pacemaker leads have to be retracted under full anticoagulation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/58. Dislocated intraocular lens fixation using intraocular cowhitch knot.PURPOSE: To describe a technique for suturing a dislocated intraocular lens (IOL) using an intraocular cowhitch knot without IOL extraction. methods: Through the sideports of paracentesis, a cowhitch knot is made outside of the anterior chamber by looping 10-0 Prolene around the haptics of the IOL. The knot is then tied in the anterior chamber by pulling up the suture. After repeating this for the opposite side, the cowhitch knots are fixated to the ciliary sulcus. RESULTS: In 4 cases treated this way, the IOL remained well positioned. CONCLUSION: This technique enables secure fixation of the IOL haptics.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/58. Bladder perforation caused by foreign body migration.lower urinary tract symptoms is a well known presentation of the presence of foreign bodies inside the bladder. Most such cases are diagnosed by chance, while investigating unrelated conditions. We present the transvesical endoscopic extraction of a surgical sponge that migrated to the bladder six years after an inguinal hernioplasty.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
