1/177. Delayed onset keratectasia following laser in situ keratomileusis.

    We present a case of unilateral iatrogenic keratectasia developing 10 months after bilateral laser in situ keratomileusis (LASIK) involving enhancement surgery using a broad-beam excimer laser (Summit Apex) to treat 6.6 diopters (D) of myopia. The ectasia progressed rapidly over the subsequent 12 months. The surgeon did not measure preoperative pachymetry, but preoperative topography and corneal measurements did not reveal underlying keratoconus or forme fruste keratoconus. corneal transplantation was required for final visual rehabilitation. light microscopy of the button revealed no underlying inflammation, which suggests biomechanical corneal weakening as the cause of the ectasia. Scanning electron microscopy showed the dramatic thinning seen clinically. latrogenic keratectasia appears to be a possible complication of LASIK.

3/177. Iatrogenic injury in videolaparoscopic cholecystectomy: difficult surgical correction biliary tract.

    Two cases of biliary tract serious lesions during videolaparoscopic cholecystectomy are reported. In the first case of lithiasic cholecystitis there had been a complete damage of the common biliary duct; in the second case there had been a double main biliary duct binding with removal of a biliary tract segment. In both cases a biliary confluence-jejunal anastomosis with Roux-en-Y loop was made up. In the first one the operation was difficult because of the main bile duct's fragility and modest expansion. In the second one the presence of a secondary biliary duct in gallbladder fossa not recognized, but drained outside with a common drainage placed during the operation prevented appearance of jaundice with dilatation of biliary ducts. It was heavily conditioned performing confluence-jejunal anastomosis with Roux-en-Y loop. The post-operative course was characterized by appearance of an external biliary fistula which has spontaneously disappeared. One year later, neither of the two patients had any stenosis or cholangitis problems.

4/177. Diaphragmatic hernia seen as a late complication of laparoscopic cholecystectomy.

    Laparoscopic surgery has emerged as the standard of care for the elective operative management of symptomatic gallbladder disease. The surgical literature is now beginning to accumulate sufficient case numbers that more clearly define the associated morbidity of this type of surgery. This article reports an instance of iatrogenic injury to the right muscular hemidiaphragm and subsequent hernia after laparoscopic cholecystectomy.

5/177. Acute angle closure glaucoma precipitated by intranasal application of cocaine.

    We describe a patient who developed acute angle-closure glaucoma following the application of topical intranasal cocaine. A 46-year-old woman underwent an elective antral washout under general anaesthesia and with local application of 25 per cent cocaine paste to the nasal mucosa. Twenty-four hours post-operatively the patient developed sudden painful blindness which was found to be due to acute glaucoma. cocaine with its indirect sympathomimetic activity causes mydriasis, that can precipitate acute angle-closure glaucoma in predisposed individuals with a shallow anterior chamber. Although the incidence is rare, otolaryngologists need to be aware of this potential complication.

6/177. Treatment of iatrogenic previable premature rupture of membranes with intra-amniotic injection of platelets and cryoprecipitate (amniopatch): preliminary experience.

    OBJECTIVE: Our aim was to describe the treatment of iatrogenic previable premature rupture of membranes with the intra-amniotic injection of platelets and cryoprecipitate (amniopatch). STUDY DESIGN: patients with iatrogenic previable premature rupture of membranes and without evidence of intra-amniotic infection underwent transabdominal intra-amniotic injection of platelets and cryoprecipitate through a 22-gauge needle. The study was approved by the Institutional review Board of St Joseph's Hospital in Tampa, florida, and all patients gave written informed consent. RESULTS: Seven patients with iatrogenic preterm premature rupture of membranes underwent placement of an amniopatch. Membrane sealing was verifiable in 6 of 7 patients. Three patients had iatrogenic preterm premature rupture of membranes after operative fetoscopy, 3 cases were after genetic amniocentesis, and 1 was after diagnostic fetoscopy. Three pregnancies progressed well, with restoration of the amniotic fluid volume and no further leakage. Two patients had unexplained fetal death despite successful sealing. One case of bladder outlet obstruction had no further leakage, but oligohydramnios persisted and did not allow unequivocal documentation of sealing. One patient miscarried from twin-twin transfusion, but the amniotic cavity was sealed. CONCLUSIONS: Iatrogenic preterm premature rupture of membranes can be treated effectively with an amniopatch. The technique is simple and does not require knowledge of the exact location of the defect. Unexpected fetal death from the procedure may be attributable to vasoactive effects of platelets or indigo carmine. Although the appropriate dose of platelets and cryoprecipitate needs to be established, the amniopatch may mean that iatrogenic preterm premature rupture of membranes no longer needs to be considered a devastating complication of pregnancy.

7/177. Treatment of a retroperitoneal lymphocele after lumbar fusion surgery with intralesional povidone iodine: technical case report.

    OBJECTIVE AND IMPORTANCE: This case report illustrates an uncommon complication from the retroperitoneal exposure of the lumbar spine. The diagnosis and management of a retroperitoneal lymphocele is presented. The lymphocele was treated with intralesional povidone iodine (Betadine; Purdue-Frederick, Norwalk, CT), which eradicated the lesion and provided symptomatic relief to the patient. CLINICAL PRESENTATION: A young woman developed an iatrogenic, rapidly progressive spondylolisthesis after having undergone three previous lumbar surgeries for radiculopathy at the L5-S1 level. INTERVENTION: A back-front-back approach was used for operative reduction and fusion of the spondylolisthesis. The patient's postoperative course was complicated by a retroperitoneal lymphocele. She presented with symptoms of urinary urgency and incontinence. The lymphocele was successfully treated with repeated drainage and sclerosis with povidone iodine. The patient ultimately developed a solid fusion, and her pain resolved. CONCLUSION: A retroperitoneal lymphocele is an uncommon complication caused by the surgical exposure of the lumbar spine when a ventral approach is used. In this case, it was diagnosed and treated without further surgical intervention.

8/177. Successful completion of endoluminal repair of an abdominal aortic aneurysm after intraoperative iatrogenic rupture of the aneurysm.

    PURPOSE: A method of achieving successful completion of endoluminal repair of an abdominal aortic aneurysm (AAA) in the presence of intraoperative iatrogenic rupture of the aneurysm is reported. methods: An 83-year-old woman with an AAA that was 7 cm in diameter was treated electively by means of endoluminal repair with a Vanguard bifurcated prosthesis (boston Scientific, Natick, Mass). No difficulty was experienced with the introduction of the delivery catheter, despite extreme angulation in the aneurysm. An acute episode of hypotension prompted an aortogram to be performed. Extravasation of contrast outside the aneurysm sac was demonstrated. The balloon on the delivery catheter was immediately advanced to the suprarenal aorta and inflated. hypotension was reversed, and hemodynamic stability was restored, thus enabling deployment of the prosthesis to proceed and the repair to be completed by means of the endoluminal method. RESULTS: The patient's blood pressure remained stable after deflation of the balloon, allowing a postprocedure aortogram to be performed. Exclusion of the aneurysm sac was demonstrated. Exclusion of the aneurysm sac from the circulation and a large retroperitoneal hematoma were confirmed by means of a postoperative contrast computed tomography scan. convalescence was complicated by acute renal failure, pneumonia, and prolonged ileus. The patient remained well and active at the follow-up examination 6 months after operation. CONCLUSION: Iatrogenic perforation of an AAA during endoluminal repair may be treated by endovascular means and does not necessarily require conversion to open repair, although this may be the safest option.

9/177. Anterior segment ischemia and retinal detachment after vertical rectus muscle surgery.

    PURPOSE: The authors describe the clinical course of a woman who developed two complications following vertical strabismus repair: anterior segment ischemia (ASI) and retinal detachment. methods: A 62 year-old woman is described. She presented with new onset proptosis and left hypertropia with significant diplopia in all fields of gaze. This presentation, her 15 year history of thyroid disease, and preoperative computed tomography (CT) of the orbits were consistent with Graves' ophthalmopathy. Vertical strabismus repair was carried out by recessing the left superior rectus muscle and resecting the left inferior rectus muscle. RESULTS: The diplopia was eliminated. The patient developed significant postoperative ASI and iatrogenic rhegmatogenous retinal detachment in the left eye due to unsuspected globe perforation. She was treated with systemic corticosteroids and radial scleral buckling. CONCLUSIONS: Severe ASI following strabismus surgery is a well recognized complication, with age, thyroid ophthalmopathy, and manipulation of the vertical rectus muscles as risk factors. The retinal detachment soon after strabismus surgery was difficult to detect, possibly due to diminished visualization of the posterior segment as a result of ASI.

10/177. Aortocoronary saphenous vein autograft accidentally attached to a coronary vein: follow-up angiography and surgical correction of the resultant arteriovenous fistula.

    The fate of aortocoronary saphenous vein bypass graft to the left anterior descending (LAD) coronary vein is reported. The vein graft communicated with the coronary sinus through the proximal LAD vein, producing a functional coronary arteriovenous fistula. The LAD vein was totally occluded distally at follow-up four months after operation. The natural history of congenital fistulas between coronary arteries and the coronary sinus suggested that bacterial endocarditis, pulmonary hypertension, and cardiac failure were all possible future complications in this patient. Operation was performed to revascularize the LAD artery to relieve persistent angina, and to close the fistula. Postoperative angiography showed a patent graft to the LAD artery with complete obliteration of the fistula. The patient is asymptomatic ten months after operation.
