3/35. Immediate postoperative thrombolytic therapy: an aggressive strategy for neurologic salvage when cerebral thromboembolism complicates carotid endarterectomy.A 42-year-old man with a high-grade left internal carotid artery (ICA) stenosis demonstrated on a duplex scan was referred to us. A cerebral arteriogram confirmed a greater than 90% left internal carotid stenosis, but with the unexpected finding of a moderate amount of thrombus in the proximal ICA. He underwent emergent left carotid endarterectomy, but during the operation, only a small amount of thrombus was identified as adherent to the atherosclerotic plaque. he awakened in the operating room with a dense right hemiplegia and aphasia. Immediate reexploration demonstrated a patent endarterectomy site, a distal thromboembolectomy was performed without extraction of thrombus, and urokinase (250,000 Units) was infused into the distal ICA. He reawakened with an unchanged right hemiplegia and aphasia. The patient then underwent an urgent postoperative carotid and cerebral arteriogram that demonstrated an embolus to the middle cerebral artery. he was treated with the superselective infusion of urokinase (500,000 Units), with almost complete resolution of the clot. Over the course of the next 48 hours, the patient made a nearly complete neurologic recovery, and he was discharged from the hospital with only a slight facial droop. At 2 months' follow-up he was completely neurologically healthy. To our knowledge this is the first reported case of urokinase administered in the immediate postoperative period in the angiography suite to treat a thromboembolus complicating a carotid endarterectomy.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
4/35. Is the loss of gallstones during laparoscopic cholecystectomy an underestimated complication?Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan.Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
5/35. Expulsive hemorrhage before phacoemulsification.A 65-year-old white man who was scheduled for cataract extraction experienced a sudden increase in intraocular pressure (IOP) with flattening of the anterior chamber immediately after the anterior capsule incision. The eye was sutured, and because no decrease in pressure was noted, surgery was postponed. The presence of the cataract prevented ophthalmoscopic examination. Echographic examination revealed a hemorrhagic choroidal detachment with involvement of the ciliary body. The patient was examined regularly until the choroidal detachment disappeared 4 weeks later. He then had uneventful phacoemulsification and intraocular lens implantation.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
6/35. Luxated intraocular lens fixation using intravitreal cow hitch (girth) knot.OBJECTIVE: To describe a technique for suturing a luxated intraocular lens (IOL) in the vitreous cavity to the ciliary sulcus using intraocular cow hitch (girth) knots without IOL extraction. DESIGN: Non-comparative interventional case series. PARTICIPANTS: Five patients with a luxated IOL in the vitreous cavity. INTERVENTION: All patients underwent surgery to fixate the IOL using this technique. methods: A three-port vitrectomy was performed in all five cases. A needle with looped 10-0 polypropylene was introduced into the vitreous cavity through a sclerotomy incision, and only the needle was passed out of the eye, guided by a bent 27-gauge needle from the 3-o'clock position 1.5 mm from the limbus. A cow hitch (girth) knot at the end of the loop was made outside the globe, grasped with a straight intravitreal forceps, and introduced into the vitreous cavity. Hooking the cow hitch (girth) knot around the haptics of the IOL in the vitreous cavity, the 10-0 polypropylene was pulled so that the IOL haptic was fixated onto the sulcus. After the opposite haptic was brought into the anterior chamber, the 10-0 polypropylene was looped around the haptics of the IOL and manipulated with a push-and-pull hook in the anterior chamber through the two corneal side ports to make a cow hitch (girth) knot outside the anterior chamber. By pulling up the suture, the knot was brought back and tied in the anterior chamber. It was then fixated to the ciliary sulcus at the 9-o'clock position. MAIN OUTCOME MEASURES: patients were evaluated for visual acuity, refraction, and surgical complications associated with the procedure. RESULTS: In all five cases, the IOL fixated stably and remained well positioned. No significant intraoperative or postoperative complications occurred. CONCLUSIONS: This technique enables secure fixation of the luxated IOL in the vitreous without extracting it.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
7/35. Vascular and bowel complications during retroperitoneal laparoscopic surgery.PURPOSE: We report on vascular and bowel complications during major retroperitoneal laparoscopic renal and adrenal surgery. MATERIALS AND methods: A total of 404 patients underwent retroperitoneoscopy for various renal and adrenal pathology between July 1997 and February 2001. The occurrence of intraoperative vascular and bowel injuries, specific intraoperative circumstances, management techniques and outcomes were evaluated. RESULTS: There were 7 vascular injuries (1.7%) and 1 bowel injury (0.25%), which involved the right adrenal vein (2), left renal vein (2), right renal vein (1), right renal artery (1), inferior vena cava (1) and a superficial, small serosal injury to the duodenum (1). Of these 8 cases 5 (63%) had been treated prior with major open intra-abdominal surgery. Average blood loss for patients with vascular injuries was 1,186 cc (range 300 to 3,000). Of the 8 cases 1 was converted to open surgery and in another 2 cases the vascular injury was controlled through the extraction incision, which had already been created. Retroperitoneoscopic control and repair without open conversion were possible in each of the most recent 5 cases. Of the 404 cases open conversion has not been necessary for control of vascular or bowel complications in the most recent 200 cases, demonstrating the impact of the learning curve. CONCLUSIONS: During major renal and adrenal retroperitoneoscopic surgery our incidence of vascular and bowel injuries was 1.7% and 0.25%, respectively. With experience inadvertent vascular and bowel injuries can be efficaciously controlled retroperitoneoscopically despite the somewhat small operative field available.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
8/35. Intraoperative transesophageal echocardiography in the early detection of acute tamponade after laser extraction of a defibrillator lead.Laser-assisted intracardiac lead extraction is associated with a 1%-2% incidence of pericardial tamponade. Because of this risk, many of these procedures are being performed in an operating room with a cardiac surgeon immediately available. Transesophageal echocardiography is a useful intraoperative monitor during these procedures.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
