1/8. Late traumatic wound dehiscence after phacoemulsification.Scars from scleral tunnel or clear corneal incisions for phacoemulsification should theoretically be stronger than the larger incisions of planned extracapsular cataract extraction. They should also be more resistant to blunt trauma. We present a case of scleral tunnel wound dehiscence and expulsion of a posterior chamber silicone intraocular lens after blunt trauma.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/8. Ultrasound biomicroscopy of chronic hypotony after cataract extraction.Ultrasound biomicroscopy was performed with a UBM 840 (Zeiss-Humphrey) equipped with a 50 MHz probe on a patient with chronic hypotony 1 year after cataract surgery by phacoemulsification with intraocular lens implantation in the capsular bag. This sonographic technique, which provides high-resolution imaging of the anterior segment, showed aqueous humor leakage through the former scleral tunnel incision. Ultrasound biomicroscopy helped detect this patient's postoperative complication and is a good tool for diagnostic procedures in patients with chronic hypotony.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
3/8. Traumatic wound dehiscence following cataract surgery: a thing of the past?PURPOSE: This study compares the frequencies of traumatic wound dehiscence following extracapsular cataract extraction (ECCE) and following phacoemulsification through a self-sealing corneoscleral tunnel. methods: A retrospective review was performed of the surgical record at a British eye hospital from September 1986 to August 1993 and January 1996 to December 1998. Cases requiring surgical repair of wound dehiscence following cataract extraction were identified. The frequencies of traumatic wound dehiscence following ECCE and phacoemulsification were compared using a two by two contingency table (chi-square test). RESULTS: Twenty-one cases of traumatic wound dehiscence were identified following 5,600 ECCEs (0.4%). In 4,200 phacoemulsification procedures only one case of traumatic wound dehiscence was identified (0.02%) (p = 0.0006, OR 15.8, chi2 = 11.69). CONCLUSION: phacoemulsification through a self-sealing corneoscleral tunnel is associated with significantly less risk of traumatic wound dehiscence than is extracapsular cataract extraction. The case of wound rupture following phacoemulsification is discussed with reference to a mechanism for the injury.- - - - - - - - - - ranking = 3keywords = extraction (Clic here for more details about this article) |
4/8. Epithelial ingrowth in a phakic corneal transplant patient after traumatic wound dehiscence.PURPOSE: To report a case of epithelial ingrowth (downgrowth) occurring in a phakic corneal transplant patient after traumatic wound dehiscence with iris prolapse that was successfully eradicated with early surgical intervention. methods: Interventional case report of a 70-year-old monocular, phakic patient who developed epithelial ingrowth within 1 week of repair of a traumatic penetrating keratoplasty wound dehiscence, with reposition of the iris that had been prolapsed for 36 hours. A gradually expanding membrane developed from the surface of the reposited iris, across the anterior lens capsule. argon laser photocoagulation applied to the surface of the iris confirmed the diagnosis and outlined the extent of the epithelial tissue on the iris. RESULTS: Intraoperative peeling of the epithelial membrane from the surface of the lens and excision of the involved iris were performed combined with extracapsular cataract extraction and insertion of a posterior chamber intraocular lens via an open-sky technique through a repeat penetrating keratoplasty opening in the cornea. This resulted in complete resolution of the intraocular epithelialization. Histopathologic examination of the excised tissue confirmed the diagnosis of epithelial ingrowth. CONCLUSIONS: Reposition of traumatically prolapsed iris tissue can result in epithelial ingrowth. Early aggressive surgical intervention can successfully remove all the epithelial tissue from within the anterior segment.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/8. Lateral tarsorrhaphy for prevention of postoperative complications resulting from globe luxation.We present a case of spontaneous globe luxation and wound dehiscence that developed in a patient with proptosis 1 day after phacoemulsification with posterior chamber intraocular lens implantation. The wound was repaired and a lateral tarsorrhaphy was performed with successful prevention of further luxations. Upon cataract extraction in the patient's other eye, lateral tarsorrhaphy was performed concurrently to prevent operative complications. This report underscores the importance of lateral tarsorrhaphy performed at the time of cataract surgery to avoid postoperative globe luxation with possible wound dehiscence in patients with proptosis or shallow orbits and a history of luxation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/8. paper clip stab wounds: four case reports.Four prisoners recently evaluated at a county hospital sustained self-inflicted paper clip stab wounds of the abdomen on 22 occasions. Guidelines for management based on physical examination, abdominal films and wound exploration with paper clip extraction and short-term admission for observation have been successful in avoiding laparotomy in most instances. Evaluation and surgical treatment of penetrating abdominal injuries are controversial. Some authors propose mandatory laparotomy for all stab wounds violating the peritoneum, while others recommend selective management based on physical findings, local exploration of the wound and subsequent peritoneal lavage. Recently, four prisoners have inserted sharpened paper clips into and through the abdominal wall on 22 occasions, raising questions about the appropriate treatment of these injuries. These wounds differ from other stab wounds in several respects: 1) underlying psychiatric disturbances and the self-inflicted nature of the wound increase the difficulty of patient management; 2) attempts are often multiple, precluding repeated peritoneal lavage for evaluation; 3) the foreign body may be completely intraperitoneal; and 4) peritoneal penetration is similar to that incurred during a peritoneal tap with an 18-gauge needle. The differing presentations of these patients are reported, and a plan for management of these injuries is proposed.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/8. Epithelial downgrowth following wound dehiscence after extracapsular cataract extraction and posterior chamber lens implantation: surgical management.Epithelial downgrowth occurred along a fistulous (nonfiltering) tract containing an incarcerated anterior capsular flap after extracapsular cataract extraction and posterior chamber lens implantation complicated by wound dehiscence. Months later, a YAG posterior capsulotomy was performed before it was realized that posterior capsule opacification was associated with epithelial downgrowth involving the posterior capsule. Surgical management of epithelial downgrowth after extracapsular cataract extraction and posterior chamber lens implantation is discussed, with emphasis on the role of combined cryotherapy, dissection of the retrocorneal membrane, and complete removal of the capsular bag. Histopathologically, we found it difficult to differentiate lens epithelial cells from corneal epithelial downgrowth within the capsular bag, but monoclonal antibody for keratin may help identify corneal epithelial cells.- - - - - - - - - - ranking = 6keywords = extraction (Clic here for more details about this article) |
8/8. lead extraction in young patients with and without congenital heart disease using the subclavian approach.Pacemaker lead removal using interlocking stylets and dilator sheaths has greatly reduced the need for major surgical intervention when lead extraction is required. Previous reports have shown the utility of this method in older patients, most of whom have anatomically normal hearts. The purpose of this study is to report the results of this technique in young patients with and without congenital heart disease. There were 13 patients (M:F = 7:6) aged 9-26 years (median 13). Congenital heart disease was present in 8 of 13 patients. A total of 17 leads required removal; they had been implanted for 54 /- 24 months (range 19-94). Leads were removed from the left subclavian vein (13) or right subclavian vein (4) only. Seventeen of 18 leads were completely removed and one partially retained in the left subclavian vein. New leads were implanted from the same vein in 11 of 13 patients. Interlocking stylets and metal or flexible dilator sheaths were used in all cases except two. There was one surgical complication: a late wound dehiscence, which was easily managed. No patient required a transfusion, and there was no structural damage noted in any patient on the postoperative echocardiogram. We conclude that lead removal using interlocking stylets and dilator sheaths from the subclavian approach is an effective technique that can be used in young patients, including those with congenital heart disease.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
