Abstract
BACKGROUND Sacral nerve stimulators (SNSs) are a widely accepted, efficacious surgical option to treat patients who have failed conservative management for overactive bladder, nonobstructive urinary retention, fecal incontinence, or pelvic pain. As with all implanted devices, there are associated risks for surgical site and implant infections. There are currently no clear published data or guidelines regarding treating such infections. AIMS We present a scoping review aiming to examine the existing literature on the treatment approaches of infected SNSs. METHODS A scoping review was conducted using Preferred Reporting Items for Systematic Review and Meta-Analysis. The search strategy focused on "sacral modulation," and "infection," and "explantation," and conservative management methods such as "antibiotics." A search was conducted on medical databases, and a grey literature search was performed. RESULTS Thirty articles were included for data extraction. Articles were published between 2006 and 2022. Outcomes were reported for 7446 patients. Two hundred and seventy-four infection events were reported, giving an overall 3.7% infection rate. Most infection events were treated with explantation, although there is some discussion on the role of conservative management using oral and intravenous antibiotics in the literature. Articles also discussed considerations for future reimplantation after explantation of SNS. CONCLUSIONS There are currently no treatment protocols in the literature to help guide whether a patient is suited to conservative or surgical management. There is future scope for developing treatment algorithms to guide clinicians for optimal treatment of infected sacral neuromodulation devices.

Abstract
The purpose of this study was to describe a case and clinical course of simultaneous anterior chamber phakic intraocular lens (AC-pIOL) removal, implantation of a posterior chamber phakic intraocular implantable collamer lens (ICL), and Descemet membrane endothelial keratoplasty (DMEK). This was a case report of a 44-year-old male with a unilateral decompensated cornea from a displaced Duet-Kelman lens on his left eye that underwent pIOL extraction and implantation of a posterior chamber phakic intraocular ICL and simultaneous DMEK. After 6 months, the cornea of the left eye had regained clarity, the Descemet membrane was graft stable, and the ICL implanted was centered with good vault. Postoperative anisometropia was avoided. There was no development of cataracts or other complications. The simultaneous pIOL extraction, ICL implantation, and DMEK in our case showed good results with full restoration of anterior segment anatomy and return of transparency of the cornea. The current case shows the feasibility of the simultaneous approach instead of sequential as an alternative for patients with endothelial disease associated with AC pIOLs, restoring vision and anatomy and also avoiding postoperative anisometropia.

Abstract
BACKGROUND There are little published data regarding longer percutaneous drain durations following inflatable penile prosthesis placement; despite this, drain proponents suggest reduced scrotal hematoma formation, while detractors cite the risk of retrograde device seeding. AIM Here, we quantify the outcomes of a multi-institutional cohort with drain durations of 48 hours or greater. METHODS Data were collected retrospectively for patients undergoing primary 3-piece inflatable penile prosthesis (IPP) placement who had a postoperative drain placed. Cases were performed by 3 surgeons at 3 high-volume centers between January 1, 2020, and March 31, 2022. It was the routine practice of these surgeons to leave percutaneous drains for an interval of 48 hours or greater. R software was used to perform statistical analysis and data visualization. OUTCOMES Primary outcomes included rates of infection and hematoma formation. Secondary outcomes included device explantation. RESULTS During the study period, there were 224 patients meeting initial inclusion criteria. Of these, 15 patients had their drains removed before 48 hours, leaving 209 patients for the analysis. Mean drain duration was 67 ± 24.7 hours. The mean follow-up interval was 170 days. Diabetes mellitus was present in 84 (40%) patients with a mean hemoglobin A1c of 7.2%. Penoscrotal and infrapubic approaches were employed (n = 114 [54.5%] vs n = 95 [45.5%]). Reservoir location was split between space of Retzius and high submuscular, with space of Retzius being more common (n = 164 [78.5%] vs n = 45 [21.5%]). Discrete hematomas were observed in 7 patients, with subsequent operative intervention on 2. Notably, both of these were infection cases. There were 3 (1.4%) total device infections. Revision for noninfection causes was required in 9 (4.3%) patients. Fisher's exact testing demonstrated significant association between hematoma formation and anticoagulation and/or antiplatelet therapy (P = .017). On multivariable logistic regression, only anticoagulation and/or antiplatelet therapy remained significant (P = .035). CLINICAL IMPLICATIONS Maintaining percutaneous closed-suction bulb drains for >48 hours following IPP placement is safe. STRENGTHS AND LIMITATIONS This multi-institutional study fills a hole in IPP perioperative literature, as there have been no previously published data regarding drain durations >48 hours. The primary limitations are the retrospective nature and lack of a control population. CONCLUSION Maintaining closed-suction bulb drains for >48 hours following IPP implantation is safe and associated with infection rates comparable to other modern cohorts and a very low rate of hematoma formation.

Abstract
We report a multicenter experience of open conversions (OC) for aortic endograft infections (AEI). We retrospectively analyzed all patients who underwent OC for AEI after endovascular aneurysm repair (EVAR), from 1997 to 2021 in 12 Italian centers. The endpoints were as follows: mortality (30-days, in-hospital), major postoperative complications. Follow-up data included: survival, aortic-related complications, infection persistence or reoccurrence. Fifty-eight patients (mean age: 73.8 ± 6.6 years) were included. Median time from EVAR to OC was 14 months (interquartile range 7-45). Thirty-five patients (60.3%) were symptomatic at presentation. Aortic reconstruction was anatomic in 32 patients (55.2%), extra-anatomic in 26 (44.8%). Thirty-day mortality was 31% (18/58). Six additional patients died after 30 days during the same hospitalization (in-hospital mortality: 41.4%). Most common post-operative complications included respiratory failure (38.6%) and renal insufficiency (35.1%). During 28.1 ± 4 months follow-up, 4 aneurysm-related deaths were recorded. Infection re-occurred in 29.4% of the patients. Estimated survival was 50% at 1 year, and 30% at 5 years, and was significantly lower for patients who underwent extra-anatomic reconstructions (37 vs 61% at 1 year, 16 vs 45% at 5 years; log-rank P = .021). OC for AEI is associated with high early mortality. The poor mid-term survival is influenced by aortic complications and infection re-occurrence.

Abstract
Objective The first objective of this study was to describe the type of tarsal injuries sustained, surgery performed, and postoperative complications in greyhounds presenting to a single veterinary hospital. An additional objective of the study was to determine the surgical site infection (SSI) and explantation rate, and if any variables were associated with an increased risk of SSI and/or explantation. Animals 116 greyhounds receiving surgical intervention for a tarsal injury. Proceures Medical records from a single veterinary referral hospital were reviewed retrospectively. Data retrieved included signalment, details regarding the injury, surgical intervention, concurrent castration, surgical/anesthesia times, postoperative management, time to healing, and postoperative complications. In cases that underwent explantation, cause, time from initial surgery, and risk factors were evaluated. Results The most frequently diagnosed tarsal injuries were fracture of the central tarsal bone (CTB; 57.8%), calcaneal fracture (56.9%) and proximal intertarsal subluxation (34.5%). The most common injury combination was a CTB fracture with a calcaneal fracture (31.9%). In total 115 (99.1%) survived to discharge. Of these, 46 (40.0%) were diagnosed with an SSI and 59 (51.3%) underwent explantation. The most common indication for explantation was SSI. Concurrent medial and lateral surgical approaches was found to be associated with an increased likelihood of SSI and explantation. Clinical relevance Practitioners performing surgical intervention for tarsal injuries in greyhounds should be aware of the high SSI rate and likelihood that explantation will be required. This risk is elevated for injuries requiring a bilateral surgical approach.

Abstract
BACKGROUND AND PURPOSE Subcutaneous implantable cardioverter defibrillators (S-ICDs) have emerged in recent years as a valid alternative to traditional transvenous ICDs (TV-ICDs). Therefore, the number of S-ICD implantations is rising, leading to a consequent increase in S-ICD-related complications sometimes requiring complete device removal. Thus, the aim of this systematic review is to gather all the available literature on S-ICD lead extraction (SLE), with particular reference to the type of indication, techniques, complications and success rate. METHODS Studies were identified by searching electronic databases (Medline via PubMed, Scopus and Web of Science) from inception to 21 November 2022. The search strategy adopted was developed using the following key words: subcutaneous, S-ICD, defibrillator, ICD, extraction, explantation. Studies were included if they met both of the following criteria: (1) inclusion of patients with S-ICD; (2) inclusion of patients who underwent SLE. RESULTS Our literature search identified 238 references. Based on the abstract evaluation, 38 of these citations were considered potentially eligible for inclusion, and their full texts were analyzed. We excluded 8 of these studies because no SLE was performed. Eventually, 30 studies were included, with 207 patients who underwent SLE. Overall, the majority of SLEs were performed for non-infective causes (59.90%). Infection of the device (affecting either the lead or the pocket) was the cause of SLE in 38.65% of cases. Indication data were not available in 3/207 cases. The mean dwelling time was 14 months. SLEs were performed using manual traction or with the aid of a tool designed for transvenous lead extraction (TLE), including either a rotational or non-powered mechanical dilator sheath. CONCLUSIONS SLE is performed mainly for non-infective causes. Techniques vary greatly across different studies. Dedicated tools for SLE might be developed in the future and standard approaches should be defined. In the meantime, authors are encouraged to share their experience and data to further refine the existing variegated approaches.

Abstract
PURPOSE To evaluate 10 years of KAMRA corneal inlay explantation and associated visual outcomes. PATIENTS AND METHODS Single-site retrospective chart review of 22 cases of AcuFocus KAMRA Inlay (ACI7000PDT) explantation (range 1 week-1 year). Uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), and manifest refraction at 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year post-explantation were reviewed. RESULTS The explantation rate was 8.2% across 10 years. All patients underwent KAMRA explantation due to dissatisfaction with their vision including blurry near vision, impaired night vision, decreased vision in dim lighting, streaks or halos, haze, and double vision. Mean UDVA pre-implant was -0.01±0.13 logMAR (logarithm of the minimal angle of resolution), 0.30±0.22 logMAR pre-explant, and 0.16±0.15 logMAR post-explant (n=20). Mean UNVA pre-implant was 0.37±0.09 logMAR, 0.38±0.13 logMAR pre-explant, and 0.42±0.21 logMAR post-explant (n=20). Mean CDVA pre-implant was -0.01±0.04 logMAR and 0.05±0.11 logMAR post-explant (n=17). Mean CDVA pre-explant was 0.04±0.07 logMAR and 0.04±0.11 logMAR post-explant (n=19). Significant differences were observed between pre-implant and post-explant UDVA (p=0.009), and between pre-explant and post-explant UDVA (p=0.02). All patients (100%) had 20/20 or better CDVA pre-implant but decreased to 73.7% post-explant. Sixty percent (12/20) of the patients lost UDVA Snellen acuity lines post-explant. MRSE was -0.31±0.29 D pre-implant and +0.26±0.77 D post-explant (p=0.007) with note of a hyperopic shift. The hyperopic shift in 31.6% (6/19) of patients did not resolve after explantation. Post-explant residual corneal haze occurred in 72.7% (16/22) of patients. CONCLUSION Although the KAMRA corneal inlay is a removable device, patients may experience residual corneal haze, hyperopic shift, and deficits in UDVA after explantation compared to pre-implantation UDVA.

Abstract
Objectives We aim to scrutinize our evolving re-intervention strategies following primary endovascular aortic aneurysm repair (EVAR) - EVAR GORE SalvAge Fabric Technique (ARAFAT), aortic sac double breasting with endograft preservation, and stent-graft explantation. Methods We performed 1,555 aortic interventions over the study period, including 910 EVARs. Factors associated with the need for reintervention and the likelihood of chronic fabric fatigue failure (CFFF) were investigated. Using conventional and innovative diagnostic modalities with Prone contrASt enHanced computed tomography Angiography (PASHA), 136 endoleaks (ELs) were identified (15 type I, 98 type II; 18 type III; 5 type IV). Results Forty-four (4.84%) patients underwent re-intervention post-primary EVAR; 18 ARAFATs, 12 double breastings, and 14 explantations. Choice of re-intervention was based on patient fitness and mode of failure. Mean EL detection duration following primary EVAR was 53.3 ± 6.82 months, while mean time to re-intervention was 70.20 ± 6.98 months. The mean sac size before the primary EVAR and re-intervention was 6.00 ± 1.75 cm and 7.51 ± 1.94 cm, respectively. Polyester (61.40%) was the most commonly employed stent-graft material. Use of more than three modular stent-graft components (3.42 ± 1.31, p = 0.846); with the proximal stent-graft diameter of 31.6 ± 3.80 cm (p = 0.651) and the use of iliac limbs more than 17 mm (p = 0.364), all added together are contributing factors. We had one peri-operative mortality following explantation due to sepsis-induced multiorgan failure. Conclusions Our re-intervention strategies matured from stent graft explantation to graft preservation with endovascular relining of the stent-graft. Graft preservation with aortic sacotomy and double breasting were used to manage concealed ELs due to aortic hygroma.

Abstract
OBJECTIVE To describe the natural history, detail the treatment patterns, and identify the risk factors for cochlear implant (CI) infections in a large US cohort. STUDY DESIGN Retrospective study based on insurance claims. SETTING Optum Data Mart database: 6101 patients who received CIs from 2003 to 2019. METHODS Infections, treatments patterns, and timelines were described. A multivariable logistic regression model was used to assess the association between postoperative oral antibiotics and CI infection. RESULTS The cohort includes 4736 (77.6%) adults and 1365 (22.4%) children. Between adult and pediatric patients, rates of CI infection (5.1% vs 4.5%, P = .18) and explantation (1.2% vs 0.8%, P = .11) were not significantly different. Infections typically occurred within 5 months of surgery. Children were diagnosed with CI infection earlier than adults (median difference, -1.5 months; P = .001). Postoperative oral antibiotic supply was not associated with lower risk of CI infection in either children or adults. However, among adults, otitis media was associated with higher odds of CI infection (odds ratio, 1.41; P < .001), while higher income was associated with lower odds of CI infection (odds ratio, 0.71; P = .03). CONCLUSIONS Postoperative oral antibiotics were not associated with lower risk of infection or interventions. Otitis media episodes and lower income were associated with increased risk of infection among adults as well as intervention overall. Infection typically presented within the first 6 months after surgery, with children presenting earlier than adults. Overall, our findings serve as a resource for providers to consider in their care of patients with CIs.

Reversal of Osseointegration as a Novel Perspective for the Removal of Failed Dental Implants: A Review of Five Patented Methods. Materials (Basel) 2021; 14:7829.

Abstract
Osseointegration is the basis of successful dental implantology and the foundation of cementless arthroplasty and the osseointegrated percutaneous prosthetic system. Osseointegration has been considered irreversible thus far. However, controlled heating or cooling of dental implants could selectively damage the bone at the bone–implant interface, causing the reversal of osseointegration or “osseodisintegration”. This review compares five methods for implant removal, published as patent documents between 2010 and 2018, which have not yet been discussed in the scientific literature. We describe these methods and evaluate their potential for reversing osseointegration. The five methods have several technical and methodological similarities: all methods include a handpiece, a connecting device for coronal access, and a controlling device, as well as the application of mechanical and/or thermal energy. The proposed method of quantifying the temperature with a sensor as the sole means for regulating the process seems inadequate. A database used in one of the methods, however, allows a more precise correlation between a selected implant and the energy needed for its removal, thus avoiding unnecessary trauma to the patient. A flapless, microinvasive, and bone-conserving approach for removing failed dental implants, facilitating successful reimplantation, would benefit dental implantology. These methods could be adapted to cementless medical implants and osseointegrated percutaneous prosthetics. However, for some of the methods discussed herein, further research may be necessary.

Abstract
AIM To evaluate the causes of phakic implantable collamer lens (ICL) exchange/explantation in patients with and without keratoconus (KC) at two tertiary hospitals in Riyadh, Saudi Arabia. METHODS A retrospective chart review of all patients who underwent ICL (model V4c with central port) exchange/explantation was performed using the electronic medical record systems. All available preoperative and postoperative data were documented for each patient. RESULTS Over 7y, 2283 ICL implantation procedures were performed; 46 implants (2%) required exchange (21 implants)/explantation (25 implants), of which 14 cases (30.4%) were patients with KC. Indications for ICL exchange/explantation in non-KC group were vault measurement, cataract formation, increased intraocular pressure, inaccurate refraction, and patient dissatisfaction in 22 (68.75%), 4 (12.5%), 3 (9.37%), 2 (6.25%), and 1 (3.12%) case, respectively. The most common indication for ICL exchange/explantation in the KC group was inaccurate vault sizing in 11 patients (78.57%), inaccurate refraction in 2 patients (14.28%), and patient dissatisfaction postoperatively in 1 (7.14%) case. CONCLUSION ICL implantation results in predictable refractive outcomes over the long term with exchange/explantation rates comparable to previous literature. Improper vault size is the most common cause of ICL exchange/explantation among patients with or without KC.

Abstract
OBJECTIVE Spinal cord stimulation (SCS) has been shown to be a safe and effective therapy for patients with chronic pain. However, some patients do not obtain or maintain adequate pain relief after SCS. The goal of this study was to identify factors that affect patient outcome with regard to SCS. MATERIALS AND METHODS A retrospective analysis of electronic medical records at a single site was performed. Records for 181 patients who received SCS implants from 2014 through 2016 were collected with follow-up data captured up to August 2019. Patient outcome was measured by device explantation and patient benefit from the SCS. Study parameters included demographic characteristics, history of pain, SCS implant characteristics, and postimplantation events. RESULTS An earlier diagnosis of radiculopathy was associated with an increased risk of poor benefit (relative risk [RR], 1.81; 95% CI, 1.19-2.74; p = 0.008). Postimplantation falls were associated with an increased risk of poor benefit (RR, 2.17; 95% CI, 1.48-3.17; p = 0.009). Device manufacturer was associated with both patient benefit and explantation. Device 2 was associated with a reduced risk of poor benefit (RR, 0.52; 95% CI, 0.32-0.85; p = 0.009). Device 4 was associated with an increased risk of poor benefit (RR, 1.71; 95% CI, 1.14-2.55; p = 0.02) and increased risk of device explantation (RR, 2.69; 95% CI, 1.2-6.02; p = 0.03). CONCLUSIONS Patient outcome was associated with diagnosis, postimplantation falls, and device manufacturer. Further investigation is recommended to confirm associations through prospective studies that can more accurately quantify patient outcome over longer periods.

Abstract
OBJECTIVE Patients with a continuous-flow left ventricular assist device may show recovery of myocardial function with unloading. Identifying candidates for and predicting clinical and hemodynamic stability after left ventricular assist device explantation remain challenging. METHODS Retrospective analysis of patients who underwent evaluation for left ventricular assist device explantation following a standardized protocol from January 2016 to March 2020. Patients who met screening criteria underwent echocardiography under "baseline," "minimal net flow," and "pump stop" conditions. If the protocol criteria were met, right heart catheterization with left ventricular assist device stoppage and occlusion of the outflow graft with a balloon catheter were performed. In patients with pulmonary capillary wedge pressure less than 16 mm Hg, explantation was performed under "pump stop" conditions. RESULTS A total of 544 patients were screened. Of these, 57 (10.5%) underwent a total of 73 echocardiography under "baseline" "minimal net flow" and "pump stop" conditions and 46 underwent left ventricular assist device stoppage and occlusion of the outflow graft with balloon catheter maneuvers. Complications during the procedure were rare. Ultimately, 21 patients (3.9%) underwent explantation. The left ventricular ejection fraction at baseline was 55.5% ± 6.5%. The mean pulmonary capillary wedge pressure was 8.1 ± 2.6 mm Hg and increased to 10.7 ± 2.9 mm Hg under left ventricular assist device stoppage and occlusion of the outflow graft with a balloon catheter. A nonischemic cause of cardiomyopathy was more likely to be found in patients who underwent explantation (20/21 patients [95%], P = .020). The survival 1 year after explantation was 95.2%, with 1 death occurring 222 days after left ventricular assist device explantation. At follow-up (median 24.9 months [interquartile range, 16.4-43.1 months]), patients were in New York Heart Association class 1 (61.9%), 2 (28.6%), and 3 (9.5%). CONCLUSIONS Our 4-year experience with a standardized protocol for left ventricular assist device explantation showed a low rate of adverse events. If all criteria are met, explantation can be performed safely and with an excellent survival and functional class.

Abstract
OBJECTIVES To report the explantation rates of high frequency 10 kHz spinal cord stimulation (SCS) in a real-world setting. MATERIALS AND METHODS This is a retrospective review of patients implanted with high frequency spinal cord stimulators over a 4-year period in two outpatient private practice clinics, from July 2015 through June 2019, using the Kaplan-Meier product-limit method to estimate probabilities of implant survival over time. RESULTS The estimated median time to explantation was 3.5 years (95% confidence interval [CI] = 3.1-3.7) [Correction added on 15 October 2020, after first online publication: The preceeding sentence was amended to reflect the estimated median time.]. The estimated probabilities of implant survival beyond 1, 2, and 3 years postimplantation were 88.4% (95% CI = 81.3-93.0%), 76.5% (95% CI = 67.8-83.2%), and 60.7% (95% CI = 50.2-69.6%), respectively. The minimum (i.e., known) cumulative percentages of patients explanted by 1, 2, and 3 years postimplantation were 11.1% (14/126), 22.2% (28/126), and 32.5% (41/126), respectively. 65.9% of patients in this study had prior neurostimulation. CONCLUSIONS Recently, high frequency SCS technology has been demonstrated as more effective in treatment of lower- and leg-pain, compared to conventional low frequency SCS, in a 12-month randomized controlled trial (SENZA-RCT). Longer term results have yet to be published. In this study, we found that the explantation rate was much higher than expected, based on the prior studies demonstrating its efficacy. As the use of neuromodulation continues to grow, longitudinal data will be critical in understanding its long-term effects on treated patients.

Abstract
<p>Implant dentistry is considered to be a safe and routine surgical procedure. However, cases of life-threatening hematoma of the floor of the mouth resulting in airway obstruction were previously reported as a complication of implant placement in the anterior mandible. Massive bleeding in this anatomical site may be caused by perforating the lingual cortex and/or damaging the lingual perimandibular vessels. In the long term, dental implants can fail, mainly due to peri-implantitis, and must be removed. Explantation procedure may occasionally become a complex challenge, with a risk for various complications.<br /> Case report: This report presents the first case of life-threatening hematoma of the floor of the mouth, as a complication secondary to a failed attempt of dental implant removal at the anterior mandible. The proximity of the implant to the lingual vascular canal might have served as a cause for vascular damage during explantation.<br /> Conclusions: Implant removal complications are scarcely described in the literature. Nonetheless, damaging blood vessels during explantation should not be underestimated. Computed tomography (CT) may be of value not only in preoperative implant planning but also before implant removal in jeopardized anatomical zones such as the anterior mandible. Lingual vascular canals should be looked for on computed tomography scans.</p>.

Abstract
Background:Visceral pain can be disabling for patients and challenging to treat in the clinic. Spinal cord stimulation is a NICE approved treatment for chronic neuropathic pain, presenting potential advantages over conventional therapies for managing chronic visceral pain. Results: A retrospective study revealed that a specific type of spinal cord stimulation, BurstDRTM (Abbott, TX, USA), was effective at improving pain and quality of life in patients with chronic visceral pain. Baseline pain scores significantly correlated with change at follow-up, suggesting it may be possible to identify potential responders from the outset. BurstDR was safe: rates of revision, explantation and complications were low. Conclusion: Clinical trials exploring the long-term effects of BurstDR including a control arm are needed. Findings could have the potential to inform best practice and improve outcomes for individuals with chronic visceral pain.

Abstract
Purpose: To present a novel 4-branched endovascular aortic plug (BEVAP) for treatment of patients with infrarenal aortic graft infection. Case Reports: Two polymorbid male patients with aortic graft infections and an unsuturable diseased paravisceral aorta were treated under compassionate use with a custom-made stent-graft. The BEVAP is a factory-modified Zenith t-Branch thoracoabdominal endovascular graft with the distal tubular main graft portion removed, creating an aortic plug that excludes the abdominal aorta while maintaining perfusion to the visceral organs. The BEVAP device is deployed using a femoral approach, and the branches are accessed through an axillary approach. A standard axillobifemoral bypass is created to perfuse the lower body. One to 2 days later, the infected infrarenal graft is resected without the need of aortic clamping or closure of the aortic stump. The BEVAP device in these 2 cases resulted in thrombosis of the abdominal aorta and the infected graft prior to explantation. Conclusion: Using the BEVAP enables radical treatment of selected patients with hostile anatomy and infrarenal aortic graft infections who have an aneurysmal paravisceral aortic segment that prevents traditional radical surgical treatment with in situ reconstruction or extra-anatomical bypass.

Abstract
A 48-year-old lady presented with bilateral symptomatic uveitis. She had bilateral cosmetic iris implantation 4 years ago. She underwent bilateral cosmetic iris explantation and goniosynechialysis to open up areas of angle compromise. This patient presented before significant angle compromise. This case report also serves to highlight the serious potential risks associated with cosmetic iris implantation. Patients with cosmetic iris implants should be warned of the potential complications and advised explantation at the earliest.

Abstract
Objectives This narrative review is aiming on showing reasons for implant failure, removal techniques, and respective clinical considerations; further, the survival rate of implants in previous failed sites is examined. Materials and methods Questions have been formulated, answered, and discussed through a literature search including studies assessing implant failure and removal up to 2018. Results Studies describing reasons for implant failure, implant removal techniques, and the reinsertion of implants in a previous failed site (n = 12) were included. To date, peri-implantitis is the main reason for late implant failure (81.9%). Trephine burs seem to be the best-known method for implant removal. Nevertheless, the counter-torque-ratchet-technique, because of the low invasiveness, should be the first choice for the clinician. Regarding zirconia implant removal, only scarce data are available. Implantation in previously failed sites irrespective of an early or late failure results in 71% to 100% survival over 5 years. Conclusion If removal is required, interventions should be based on considerations regarding minimally invasive access and management as well as predictable healing. (Post)Operative considerations should primarily depend on the defect type and the consecutive implantation plans.

Postmastectomy Radiation Therapy (PMRT) before and after 2-Stage Expander-Implant Breast Reconstruction: A Systematic Review. ACTA ACUST UNITED AC 2019; 55:E226.

Abstract
Background: In those undergoing treatment for breast cancer, evidence has demonstrated a significant improvement in survival, and a reduction in the risk of local recurrence in patients who undergo postmastectomy radiation therapy (PMRT). There is uncertainty about the optimal timing of PMRT, whether it should be before or after tissue expander or permanent implant placement. This study aimed to summarize the data reported in the literature on the effect of the timing of PMRT, both preceding and following 2-stage expander-implant breast reconstruction (IBR), and to statistically analyze the impact of timing on infection rates and the need for explantation. Methods: A comprehensive systematic review of the literature was conducted using the PubMed/Medline, Ovid, and Cochrane databases without timeframe limitations. Articles included in the analysis were those reporting outcomes data of PMRT in IBR published from 2009 to 2017. Chi-square statistical analysis was performed to compare infection and explantation rates between the two subgroups at p < 0.05. Results: A total of 11 studies met the inclusion criteria for this study. These studies reported outcomes data for 1565 total 2-stage expander-IBR procedures, where PMRT was used (1145 before, and 420 after, implant placement). There was a statistically significant higher likelihood of infection following pre-implant placement PMRT (21.03%, p = 0.000079), compared to PMRT after implant placement (9.69%). There was no difference in the rate of explantation between pre-implant placement PMRT (12.93%) and postimplant placement PMRT (11.43%). Conclusion: This study suggests that patients receiving PMRT before implant placement in 2-stage expander–implant based reconstruction may have a higher risk of developing an infection.

Abstract
BACKGROUND In this retrospective analysis we evaluated a standardized echocardiographic assessment and an invasive technique for patient selection for successful continuous-flow left ventricular assist device (CF-LVAD) explantation. METHODS Inclusion criteria for LVAD recovery assessment were: clinically stable condition; LVAD support for >6 months; physical activity; normal echocardiography findings; and no more than mild valvular disease and aortic valve opening. In a second step, echocardiography was performed under CF-LVAD reduction and stop conditions (PStopE). In the third step, patients who presented with stable parameters underwent right heart catheterization under CF-LVAD stoppage and occlusion of the outflow graft with a balloon catheter. Criteria for explantation were normal pulmonary artery pressure and pulmonary capillary wedge pressure <16 mmHg. RESULTS Thirty-three of 424 patients entered the second step of evaluation and 20 entered the third step. Fourteen presented positive results and the pump was successfully explanted. The PCWP at baseline was 8.5 (2.8) mmHg in the explantation group and 10.6 (2.8) mmHg in the non-explantation group (p = 0.105). It increased to 10.9 (3.0) mmHg vs 20.8 (4.9) mmHg under outflow graft occlusion. The wedge pressure was significantly higher in the non-explantation group (p < 0.001). Median duration of follow-up after explantation was 9.74 (interquartile range 4.3 to 20.60) months, with survival of 93%. CONCLUSIONS The protocol presented is feasible and safe. The criteria applied provide good patient selection for sustained mid-term myocardial recovery after LVAD explantation.

Abstract
Although rare, recovery of cardiac function after mechanical support of the left ventricle is the most desirable therapeutic goal in the treatment of end-stage heart failure.Herein, we present a novel implantable device for explantation of the HeartMate 3™ left ventricular assist device (LVAD) in patients, following cardiac recovery, avoiding (re-) sternotomy.This article demonstrates the feasibility of applying this novel device, which fits into the sewing ring of the LVAD.This custom-made mechanical plug offers a promising alternative to standard device-explantation procedures.

Abstract
Current surgical dogma for infected aortic endografts consists of complete explantation concurrent with revascularization via extra-anatomic bypass or in situ infection-resistant conduit. However, this treatment paradigm is associated with high rates of postoperative mortality and major morbidity. Therefore, patients with prohibitive operative risk are often not offered surgical intervention. In the following manuscript, we report the successful treatment of an 85-year-old gentleman with a fenestrated aortic endograft (Cook Medical, Bloomington, Indiana) infected secondary to the formation of an aortoenteric fistula with primary bowel repair, washout, and lifelong antibiotics and followed for nearly 2 years after intervention. Therefore, this nonexplantation approach can be considered for patients who may otherwise have no surgical recourse.

Abstract
AIM To study the effects of intraocular lens (IOL) explantation and demographic characteristics. METHODS Retrospective non-comparative case series. Clinical data recorded from patient charts included the following: demographic, preoperative and postoperative characteristics; complications; surgical methods, and changes in visual acuity. RESULTS A total of 69 eyes in 67 Chinese patients who received IOL explants were studied. The patients' mean age at the time of explantation was 46.1 years old [SD 22.5 (6-85)], and 37 patients were female (55.2%). Regarding employment, 47.8% were farmers, 23.9% were retired, 16.4% were students, 4.5% were unemployed, 3% were workers, and 4.5% were other (including staff members, teachers and officers). The main reasons for explantation were dislocation/decentration in 41 cases (59.4%) and retinal detachment in 10 cases (14.5%). The third most prevalent cause was incorrect lens power in 7 eyes (10.1%). The remaining reasons were endophthalmitis in 6 cases (8.7%), posterior capsular opacity in 3 eyes (4.3%), and impacting retinal surgery operation in 2 cases (2.9%). The main comorbidities were high myopia in 18 eyes (26.1%), trauma in 8 eyes (11.6%), retinal detachment in 6 eyes (8.7%), congenital cataracts in 8 eyes (11.6%), and Marfan's syndrome in 2 eyes (2.9%). The mean time from implantation to explantation was 4.0y [SD 4.2 (0.005-15)]. Treatment after explantation included posterior chamber IOL implantation in 44 eyes (63.8%) and aphakia in 25 eyes (36.2%). After surgery, the best corrected visual ability (BCVA) was improved in 50 cases (72.5%), including 28 patients (40.6%) in whom visual ability was improved by more than two lines. CONCLUSION Dislocation/decentration is the main cause for explantation, and high myopia is a main risk factor. Posterior chamber IOL implantation remains the most elected treatment after explantation.

Abstract
PURPOSE To demonstrate explantation of the Nellix Endovascular Aneurysm Sealing (EVAS) System in the setting of infection. CASE REPORTS Two male patients, 71 and 83 years old, underwent Nellix implantation for asymptomatic infrarenal aortic aneurysms measuring 5.1 and 6.3 cm, respectively. Each developed late infections at 8 and 4 months post EVAS, respectively. The first patient experienced aneurysm rupture after medical therapy failed; the Nellix endosystem was explanted in an uneventful procedure. The second patient developed an aortoduodenal fistula, which was sutured before the Nellix device was removed without complications. The patient died 3 months later, presumably due to ongoing infection. CONCLUSION The need to explant a Nellix EVAS System due to graft infection is a straightforward procedure compared to the removal of a conventional endograft with suprarenal fixation. It requires only temporary suprarenal clamping. The devices can be easily removed due to the lack of penetrating components and without damage to the aortic segment needed to create an anastomosis.

Abstract
Preclinical research in a sheep tibia model has been conducted to evaluate the underlying mechanisms of the nontraumatic implant explantation of failed implants, which allow placing a new one in the bone bed. Twelve dental implants were placed in sheep diaphysis tibia and once osseointegrated they were explanted using a nontraumatic implant explantation approach. Implant osseointegration and explantation were monitored by means of frequency resonance, removal torque, and angle of rotation measurement. The host bone bed and the explanted implant surface were analyzed by conventional microscopy and scanning electron microscope. Results show that osseointegration was broken with an angular displacement of less than 20°. In this situation the implant returns to implant stability quotient values in the same range of their primary stability. Moreover, the explantation technique causes minimal damage to the surrounding bone structure and cellularity. This nontraumatic approach allows the straightforward replacement of failed implants and emerges as a promising strategy to resolve clinically challenging situations.

Abstract
This study was performed to study the effect of implant surface treatment on the cause and removal torque of failed nonmobile implants. Implant explantation was achieved by the application of countertorque at the implant-bone interface. The explantation socket was examined carefully and curetted to remove any granulation tissue. Immediate implant placement was accomplished when primary stability could be achieved. Eighty-one patients were treated according to the described treatment protocol for the explantation of 158 nonmobile implants in the maxilla and the mandible. The patient's mean age was 62 ± 11 years. The main cause of implant explantation was peri-implantitis (131 implants; 82.9%) followed by malpositioning of the implants (22 implants; 13.9%). The explantation of 139 implants at 146 ± 5 Ncm was performed without the need for trephine bur. However, the use of trephine burs to cut into the first 3 to 4 mm was necessary in 19 explantations, and the removal torque was 161 ± 13 Ncm. All titanium plasma-sprayed implants were removed due to peri-implantitis at a significantly lower torque when compared to acid-etched, particle-blasted, and oxidized implants. The postoperative recovery of the patients was uneventful and the conservation of the available hard and soft tissues was successfully achieved. The protocol followed in this study could constitute a real alternative to other traumatic technique for the removal of failed implants and advanced stages of peri-implantitis. The type of implant surface treatment could influence the value of removal torque and the occurrence of peri-implantitis.

Abstract
A 3 year old intact male pygmy goat developed progressive weakness and eventual recumbancy over the course of 1 week, while maintaining its ability to eat and drink. The animal died and at necropsy, the parietal pleural surfaces and the pericardial surface were noted to be covered with firm, white, variably sized nodules that often formed linear arrays or coalesced into larger clumped aggregates. The visceral pleural surfaces of the ventral lung lobes were also covered with similar nodules. Histopathological and immunohistochemical evaluation of the submitted tissues revealed a diagnosis of mesenchymal chondrosarcoma with extensive seeding throughout the thoracic cavity.

Abstract
OBJECTIVES/HYPOTHESIS To characterize revision cochlear implant surgery and quantify rates of revision and device failure. STUDY DESIGN Retrospective review of 235 cases of revision cochlear implant surgery performed at the Sydney Cochlear Implant Center over a period of 30 years, between January 1982 and June 2011. METHODS Patient demographics and characteristics of revision surgery were retrospectively extracted from a centralized database. Analyses of overall and cumulative rates were performed. RESULTS During the study period, 2,827 primary cochlear implantations were performed in 2,311 patients, with 201 primary implants in 191 patients of this cohort (109 children and 82 adults) undergoing 235 revision surgeries. The most common indication for revision surgery was device failure (57.8%), followed by migration/extrusion (23.4%), infection/wound complication (17.0%), and poor outcome/secondary pathology (6.4%). The majority of revision surgeries were reimplantations. Overall revision and device failure rates were 8.3% and 4.8%, respectively. The cumulative revision rate for primary implants at all ages increased linearly by 1% per year. The cumulative revision rate was significantly higher in children, and decreased with more recently performed implantations and with newer generations of implants. CONCLUSIONS The cumulative revision rate for primary implants suggests an ongoing linear relationship between the time of postprimary implantation and the need for revision surgery. We have formed an evidence base that characterizes the nature and frequency of revision surgery in a high-volume setting, allowing clinicians to effectively counsel prospective patients and clinics to understand the burden of revision surgery and device failure.

Abstract
Background: Grafting choices available for performing anterior cervical diskectomy/fusion (ACDF) procedures have become a major concern for spinal surgeons, and their institutions. The “gold standard”, iliac crest autograft, may still be the best and least expensive grafting option; it deserves to be reassessed along with the pros, cons, and costs for alternative grafts/spacers. Methods: Although single or multilevel ACDF have utilized iliac crest autograft for decades, the implant industry now offers multiple alternative grafting and spacer devices; (allografts, cages, polyether-etherketone (PEEK) amongst others). While most studies have focused on fusion rates and clinical outcomes following ACDF, few have analyzed the “value-added” of these various constructs (e.g. safety/efficacy, risks/complications, costs). Results: The majority of studies document 95%-100% fusion rates when iliac crest autograft is utilized to perform single level ACDF (X-ray or CT confirmed at 6-12 postoperative months). Although many allograft studies similarly quote 90%-100% fusion rates (X-ray alone confirmed at 6-12 postoperative months), a recent “post hoc analysis of data from a prospective multicenter trial” (Riew KD et. al., CSRS Abstract Dec. 2011; unpublished) revealed a much higher delayed fusion rate using allografts at one year 55.7%, 2 years 87%, and four years 92%. Conclusion: Iliac crest autograft utilized for single or multilevel ACDF is associated with the highest fusion, lowest complication rates, and significantly lower costs compared with allograft, cages, PEEK, or other grafts. As spinal surgeons and institutions become more cost conscious, we will have to account for the “value added” of these increasingly expensive graft constructs.
