When a revision surgery related with removal of failed interbody cage is required, going through the previous passage can lead to a higher risk of neurological deficits or incidental dural injuries. Recently, the lateral approach has become a popular method instead of the conventional anterior or posterior approaches. The lateral approach is also useful method to remove failed interbody cage previously placed and re-do interbody fusion with lower risks compared to revision surgery via previous passage. However, there is still some difficulty in retrieving the interbody cage from the intervertebral space because of no spacious passage, subsidence, and uncontrolled movable cage. In this study, we introduce our experience that we removed failed interbody cage more easily with only the simple additional steps of making a taphole and fixing the cage using a thread-tipped stick.

OBJECTIVETo investigate the technique of repeated operation for removement of polyacrylamide hydrogel from breast.

METHODS17 cases after uncomplete removement of PHG were reoperated through inferior periareolar incision. The PHG and affected denatured muscle and gland tissue were removed.

RESULTSPreoperative MRI or CT showed PHG distributed diffusely in muscle and gland. There was only minimal residual PHG after operation. Histological examination showed PHG distributed in the denatured and proliferative fibrous tissue, including giant cells, many neutrophilic cells infiltration, and foreign body granuloma. The symptoms, such as intramammary pump or nodule, chest and back pain, infection, were relieved after operation.

CONCLUSIONSBlinded suction technique can not remove PHG completely and can also result in malposition of PHG and make the tissue denaturation worse. We suggest open approach to remove the PHG and denatured tissue completely through periareolar incision.

Embolization of the occlusion device after percutaneous closure of atrial septal defect (ASD) is a potential disastrous complication. The usual site of embolization is the right side of the heart including pulmonary artery, but the device embolization to the extracardiac aorta is extremely rare. Here, we report a successful percutaneous retrieval case of the embolized Amplatzer Septal Occluder (ASO) to the descending thoracic aorta after the successful deployment of two ASO devices in a patient with double ASD. Competition between the two devices to obtain a stable position may be an explanation for the migration of ASO.

Summary of Event: A transjugular intrahepatic portosystemic shunt (TIPS) stent (Viatorr) was misplaced into main portal vein and superior mesenteric vein. This misplaced covered stent was then successfully retrieved using the rigid endobronchial forceps. Teaching Point: Before release the covered portion of the TIPS stent (Viatorr), it is necessary to confirm the position of uncovered portion in portal vein and covered portion in parenchymal tract. The endobronchial forceps technique is a safe and efficient method for retrieving a misplaced TIPS stent.

Objective To compare the Ambu Aura-i with the Air-Q intubating laryngeal airway for fiberoptic-guided tracheal intubation in ear deformity children.Methods Totally 120 children who were scheduled for elective auricular reconstruction surgery requiring general anaesthesia with tracheal intubation were enrolled in this prospective study. They were randomized to receive either the Ambu Aura-i (Aura-i group) or Air-Q (Air-Q group). The time for successful tracheal intubation was assessed. The attempts for successful device insertion, leak pressures, cuff pressures, fiberoptic grade of laryngeal view, time for removal of the device after endotracheal intubation, and complications were recorded. Results Device placement, endotracheal intubation, and removal after endotracheal intubation were successful in all patients. The Air-Q group required longer time than the Aura-i group in device placement[(14.1±7.2) s vs. (10.8±5.2) s, P<0.05], successful endotracheal intubation [(39.8±9.5) s vs. (24.1±8.2) s, P<0.05], and device removal [(18.2±5.1) s vs. (14.7±3.7) s, P<0.05]. There were no differences in fiberoptic grade of view between these devices, and the percentage of glottis seen was 80.0% (Air-Q group) vs. 86.7% (Aura-i group). The leak pressure was (20.5±4.8) cmHO in the Air-Q group and (22.2±5.0) cmHO in the Aura-i group (P<0.05), and the cuff pressure was (22.9±11.5)cmHO in the Air-Q group and (33.9±15.9) cmHO in the Aura-i group (P<0.05). Hemodynamic changes were not significantly different between two group. The incidence rate of sore throat two hours after operation was 6.5% (n=4) in the Air-Q group and 5% (n=3) in the Aura-i group. Conclusion Both Ambu Aura-i and Air-Q intubating laryngeal airway are effective conduits for beroptic-guided tracheal intubation, with advantages including simple operation, high success rate, and fewer complications, especially the Ambu Aura-i.

OBJECTIVETo explore the relationship between mammaplasty and results after polyacrylamide hydrophilic gel (PAHG) removal from breast.

METHODSFrom Feb. 2003 to Aug. 2009, 130 patients with bilateral breast augmentation by PAHG injection were treated. Preoperative ultrasound examination and MRI were performed to know the distribution of PAHG and infiltration at the surrounding tissue. According to the conditions after removal, the patients were received implant augmentation immediately, or at the second stage, or no implant.

RESULTSThe patients were followed up for 3 months at the most with a very satisfactory rate of 63.84% (83/120), a satisfactory rate of 31.53% (41/120) and a unsatisfactory rate of 4.63% (6/120). Slight capsular contracture (Baker I) occurred in 5 cases with 6 breasts in satisfactory group. All the patients in unsatisfactory groups who selected unsuitable implants by themselves were re-operated to take out the implants. 3 cases with much residue PAHG insisted to receive breast implants. Among them, 2 cases achieved acceptable results even the surface of the breasts were not smooth. No other complication happened.

CONCLUSIONSThe breast reaugmentation after PAHG removal should be performed based on the deformity and condition of breast. Both cosmetic result and psychological relief could be obtained after mammaplasty.

OBJECTIVEThe aim of this study is to investigate the safety and effectiveness of Excimer laser-assisted lead extraction.

METHODSConsecutive lead extraction in 16 patients using the excimer laser sheath from Veterans Administration Medical Center, University of Minnesota between March 2008 and December 2009 were analyzed retrospectively. The clinical characteristics including basic disease, cardiac function, indication and reason for lead removal, lead characteristic, and complication were summarized.

RESULTSThirty one leads (laser sheaths were used in 25 leads) in 16 patients [mean age (67.4 ± 9.1) years, range 54 - 82 years] were extracted. All leads were extracted successfully without complication. Most patients had severe heart diseases with left ventricular ejection fraction of 20% - 60% (mean 36.4% ± 13.4%). Mean implant time was (73.9 ± 62.9) months (range 3 - 251 months). Nine patients had Class I indications for lead extraction, 7 patients for Class II indications. Atrial lead fractured in one patient during lead extraction, the remaining part of the lead was taken out from femoral vein by a snare-catheter apparatus. Another patient developed CS dissection and small pericardium perfusion during LV lead implantation (upgrade to BiV-ICD) post successful lead extraction and patient discharged without complication.

CONCLUSIONOur single center experience suggests that Excimer Laser Sheath Lead Removal System is safe and effective in extracting pacemaker and ICD leads.

PURPOSE: Supraglottic airway devices have been widely utilized as an alternative to tracheal intubation in various clinical situations. The rotation technique has been proposed to improve the insertion success rate of supraglottic airways. However, the clinical efficacy of this technique remains uncertain as previous results have been inconsistent, depending on the variable evaluated. MATERIALS AND METHODS: We systematically searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials in April 2015 for randomized controlled trials that compared the rotation and standard techniques for inserting supraglottic airways. RESULTS: Thirteen randomized controlled trials (1505 patients, 753 with the rotation technique) were included. The success rate at the first attempt was significantly higher with the rotation technique than with the standard technique [relative risk (RR): 1.13; 95% confidence interval (CI): 1.05 to 1.23; p=0.002]. The rotation technique provided significantly higher overall success rates (RR: 1.06; 95% CI: 1.04 to 1.09; p<0.001). Device insertion was completed faster with the rotation technique (mean difference: -4.6 seconds; 95% CI: -7.37 to -1.74; p=0.002). The incidence of blood staining on the removed device (RR: 0.36; 95% CI: 0.27 to 0.47; p<0.001) was significantly lower with the rotation technique. CONCLUSION: The rotation technique provided higher first-attempt and overall success rates, faster insertion, and a lower incidence of blood on the removed device, reflecting less mucosal trauma. Thus, it may be considered as an alternative to the standard technique when predicting or encountering difficulty in inserting supraglottic airways.
