RESUMO
BACKGROUND: Biliary cannulation is readily achieved in > 85% of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). When standard cannulation techniques fail, salvage techniques utilized include the needle knife precut, double wire technique, and Goff septotomy. METHODS: Records of patients undergoing ERCP from 2005 to 2016 were retrospectively examined using a prospectively maintained endoscopy database. Patients requiring salvage techniques for biliary access were analyzed together with a control sample of 20 randomly selected index ERCPs per study year. Demographic and clinical variables including indications for ERCP, cannulation rates, and adverse events were collected. RESULTS: A total of 7984 patients underwent ERCP from 2005 to 2016. Biliary cannulation was successful in 94.9% of control index ERCPs, 87.2% of patients who underwent Goff septotomy (significantly higher than for all other salvage techniques, p ≤ 0.001), 74.5% of patients in the double wire group and 69.6% of patients in the needle knife precut group. Adverse event rates were similar in the Goff septotomy (4.1%) and index ERCP control sample (2.7%) groups. Adverse events were significantly higher in the needle knife group (27.2%) compared with all other groups. CONCLUSIONS: This study represents the largest study to date of Goff septotomy as a salvage biliary access technique. It confirms the efficacy of Goff septotomy and indicates a safety profile similar to standard cannulation techniques and superior to the widely employed needle knife precut sphincterotomy. Our safety and efficacy data suggest that Goff septotomy should be considered as the primary salvage approach for failed cannulation, with needle knife sphincterotomy restricted to Goff septotomy failures.

OBJECTIVES/HYPOTHESIS: To analyze stapler benefits in salvage total laryngectomy in terms of surgical time, hospitalization length, oral feeding time, and occurrence of pharyngocutaneous fistula, and to evaluate risk factors for its onset. STUDY DESIGN: Retrospective analysis. METHODS: One hundred fourteen patients affected by endolaryngeal squamous cell carcinoma who underwent salvage total laryngectomy following primary treatment failure were reviewed. We divided patients into two groups based on type of pharyngeal suture performed: mechanical suture with stapler (group A) and manual suture (group B). These two groups were compared for surgical time, start of oral feeding, hospitalization length, surgical margins and pharyngocutaneous fistula incidence considering its relationship with diabetes mellitus, nutritional status, primary treatment, and neck dissection. RESULTS: In group A and group B, oral feeding restarting time was 15 ± 9.33 versus 20.03 ± 13.81 days, hospitalization was 17.63 ± 10.08 versus 23.72 ± 14.29 days, and surgery lasted 268.39 ± 76.93 versus 294.26 ± 140.58 minutes, respectively (P < .05). Surgical margins resulted infiltrated in two patients (4.3%) in group A and 12 patients in group B (17.6%) (P = .03). Twenty-one patients (18.4%) presented with pharyngocutanoeus fistula. In group A and group B the incidence of fistula was 15.2% and 20.6%, respectively (P = .468). Fistula occurred in 7 of 18 diabetic patients (38.9%) and 14 of 96 (14.6%) nondiabetic patients (P = .015). Nineteen fistulas (90.5%) occurred in patients who had undergone previous radiation treatment (P = .013). CONCLUSIONS: Using a stapler shortened operative time and hospitalization, while also providing a faster restart of oral feeding. Moreover, mechanical pharyngeal suture seems to decrease fistula rate even though its prevention role in salvage laryngectomy should be confirmed by further studies. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:E473-E478, 2021.

BACKGROUND: Chemosaturation with percutaneous hepatic perfusion (CS-PHP; Hepatic CHEMOSAT® Delivery System; Delcath Systems Inc, USA) is a novel interventional procedure, which delivers high doses of melphalan directly to the liver in patients with liver tumors while limiting systemic toxicity through hemofiltration of the hepatic venous blood. We have previously shown promising efficacy for patients with ocular melanoma (OM) and cholangiocarcinoma (CCA) within our single-center and multi-center experiences. The aim of this study was to analyze the safety and efficacy of CS-PHP after 141 treatments at Hannover Medical School, Germany. METHODS: Overall response rates (ORR) were assessed according to Response Evaluation Criteria In Solid Tumors (RECIST1.1). Median Overall survival (mOS), median progression-free survival (mPFS), and median hepatic PFS (mhPFS) were analyzed using the Kaplan-Meier estimation. RESULTS: Overall, 60 patients were treated with CS-PHP in the salvage setting from October 2014 until January 2019 at Hannover Medical School with a total of 141 procedures. Half of the patients were patients with hepatic metastases of ocular melanoma (OM) (n = 30), 14 patients had CCA (23.3%), 6 patients had hepatocellular carcinoma (10%), and 10 patients were treated for other secondary liver malignancies (16.7%). In total, ORR and disease stabilization rate were 33.3% and 70.3% (n = 25), respectively. ORR was highest for patients with OM (42.3%), followed by patients with CCA (30.8%). Independent response-associated factors were normal levels of lactate dehydrogenase (odds ratio (OR) 13.7; p = 0.015) and diagnosis with OM (OR 9.3; p = 0.028). Overall, mOS was 9 months, mPFS was 4 months, and mhPFS was 5 months. Patients with OM had the longest mOS, mPFS, and mhPFS with 12, 6, and 6 months, respectively. Adverse events included most frequently significant, but transient, hematologic toxicities (80% of grade 3/4 thrombopenia), less frequently hepatic injury up to liver failure (3.3%) and cardiovascular events including two cases of ischemic insults (5%). CONCLUSION: Salvage treatment with CS-PHP is safe and effective particularly in patients OM and CCA. Careful attention should be paid to possible, serious hepatic, and cardiovascular complications.

BACKGROUND: Because auricular reconstruction is a complex and relatively uncommon procedure, there are many patients that have had disappointing reconstructions. This study describes the authors' large experience with secondary procedures in patients with unsatisfactory or failed initial ear reconstruction. METHODS: A prospectively maintained database of all consecutive patients who underwent secondary total ear reconstruction from March of 1991 to December of 2017 was reviewed. Demographic data and outcomes were assessed. Patients with acquired absence of the ear were not included. RESULTS: There were 144 microtia patients that met the inclusion criteria. Patient age at the time of the secondary reconstruction ranged from 3 to 59 years. Follow-up duration ranged from 1 to 21 years. Primary reconstruction was performed with rib cartilage in 91 patients, porous polyethylene implant in 47 patients, prosthesis in four patients, and irradiated cadaver rib cartilage in two patients. All secondary reconstructions were performed with porous polyethylene implants. The alloplastic framework was covered with a temporoparietal fascia flap in 76 patients, an occipital fascia flap in 64 patients, and a free fascia flap in four patients (two radial forearm flaps in the same patient, one contralateral temporoparietal fascia flap, and one lateral arm flap). Fourteen patients (10 percent) had complications requiring revision surgery. Secondary surgery was successful in all but one patient. CONCLUSIONS: These data represent the largest series of secondary total ear reconstructions. The use of a porous polyethylene implant is an ideal method for these patients because of its minimal morbidity and relatively low complication rate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

BACKGROUND: Periprosthetic infections represent major complications in breast reconstruction, frequently leading to expander-implant loss. No consensus regarding a management algorithm for attempted salvage currently exists. This study assessed outcomes of the authors' salvage protocol using an antibiotic-impregnated polymethylmethacrylate implant with expander device exchange. METHODS: A retrospective chart review identified infected implant-based breast reconstruction cases treated between 2009 and 2017. Of 626 cases initially identified, a total of 62 cases had severe prosthetic infections, and underwent either prosthetic salvage (n = 45) or immediate explantation (n = 17). All the prosthetic salvage patients received intravenous antibiotics followed by surgical débridement, insertion of polymethylmethacrylate plates, device exchange, and postoperative antibiotics. After clinical resolution of infection, tissue expansion was performed, with the polymethylmethacrylate plates remaining in situ until exchanged for permanent implants. RESULTS: The authors' study demonstrated a primary infection clearance rate of 82.2 percent (n = 37). Compared to the traditional explantation group, a significantly higher percentage of the salvage patients completed final reconstruction (84.4 percent versus 35.3 percent; p < 0.001). Fewer patients abandoned reconstruction efforts after infection clearance (2.2 percent versus 58.8 percent; p < 0.001). The majority of cases (78.8 percent) that succeeded the salvage protocol ultimately received implant-based reconstruction; 62.5 percent that failed the salvage protocol still went on to receive autologous tissue reconstruction. CONCLUSIONS: Sustained local antibiotic delivery using polymethylmethacrylate implants and expander device exchange can successfully salvage an infected breast expander/implant. Compared with the traditional explantation approach, more patients complete final reconstruction. Other benefits include preserved skin envelope integrity and possibly improved long-term aesthetic outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

BACKGROUND: This study investigated the risk of reconstruction failure after mastectomy, immediate breast reconstruction, and radiotherapy to either a temporary tissue expander or permanent implant. METHODS: Records of women treated at a single institution between June of 1997 and December of 2011 were reviewed. Two patient groups were identified based on type of immediate breast reconstruction: tissue expander followed by exchange with a permanent implant and permanent implant. The study endpoint was rate of reconstruction failure, defined as a replacement, loss of the implant, or conversion to flap. RESULTS: The tissue expander/permanent implant and the permanent implant groups consisted of 63 and 75 patients, respectively. The groups were well balanced for clinical and treatment characteristics. With a median follow-up of 116 months, eight implant losses, 50 implant replacements, and four flap conversions were recorded. Reconstruction failure occurred in 22 of 63 patients in the expander/implant group and in 40 of 75 patients in the permanent implant group. A traditional proportional hazards model showed a higher risk of reconstruction failure for the expander/implant group (hazard ratio, 2.01) and a significantly shorter time to reconstruction failure compared with the permanent implant group (109.2 months versus 157.7 months; p = 0.03); however, according to a competing risk model, the between-groups cumulative incidences were not significantly different (hazard ratio, 1.09). CONCLUSIONS: Radiotherapy to either a tissue expander or a permanent implant presented a fairly large risk of reconstruction failure over time. The expander/implant group was not more likely to develop reconstruction failure compared to permanent implant group, but the timing of onset was shorter. More complex techniques should be investigated to lower the risk of reconstruction failure. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

OBJECTIVE: There is currently uncertainty regarding the ideal treatment to salvage thrombosed or failing synthetic arteriovenous grafts (AVGs) in patients with end stage renal disease. Therefore, a systematic review up to December 2018 and network meta-analysis of randomised control trials (RCTs) that compared three month failure risk of available treatments was carried out. METHODS: Medline, Scopus, Embase, and the Cochrane Library were the data sources. Pairwise meta-analyses were based on random effects models. Network meta-analysis was conducted within a frequentist framework with a multivariable random effects approach to model treatment effects across studies. The metric of choice was the odds ratio (OR) along with the associated 95% confidence interval (CI). RESULTS: Sixteen two arm RCTs were included involving 2011 patients who were randomised to six different treatments (plain balloon angioplasty, open surgical repair, stents, stent grafts, drug eluting balloons (DEBs), and cutting balloons). The network of RCTs had a star like geometry with plain balloon angioplasty being the common comparator. There were no significant differences between treatments with regards to risk of failure at three months with the exception of stent graft use that significantly reduced the risk of failure compared with plain balloon angioplasty (OR 0.53, 95% CI 0.34-0.84). Based on surface under the cumulative ranking curve (SUCRA) values, the best interventions to salvage thrombosed or failing AVGs were DEB and stent grafts. CONCLUSIONS: Stent graft seems to perform better than plain balloon angioplasty in terms of saving thrombosed or failing AVGs. However, this network meta-analysis was limited by the lack of closed loops and thus unable to assess consistency between direct and indirect evidence. The efficacy of DEBs as a promising treatment deserves further investigation and new RCTs are required.

Background: Endoluminal vacuum-assisted therapy (EVT) has been introduced recently to treat colorectal anastomotic leakage. The aim of this study was to evaluate the safety and efficacy of EVT in the treatment of anastomotic leakage and rectal stump insufficiency after Hartmann's procedure. Methods: A systematic search of MEDLINE, Scopus and Cochrane databases was performed using search terms related to EVT and anastomotic leakage or rectal stump insufficiency in line with the PRISMA checklist. Observational studies, RCTs and case series studies published to July 2017 were included. Primary outcomes of the review were the success of EVT, defined as complete or partial healing of the anastomotic defect and associated cavity, and the rate of stoma reversal after EVT. Secondary outcomes included the duration of treatment to complete healing, complications of treatment and the need for further intervention. A meta-analysis was conducted. The potential effect of clinical confounders on the failure of EVT was investigated using the random-effects meta-regression model. Results: Of 476 articles identified, 17 studies reporting on 276 patients were ultimately included. The weighted mean rate of success was 85·3 (95 per cent c.i. 80·1 to 90·5) per cent, with a median duration from inception of EVT to complete healing of 47 (range 40-105) days. The weighted mean rate of stoma reversal across the studies was 75·9 (64·6 to 87·2) per cent. Twenty-five patients (9·1 per cent) required additional interventions after EVT. Thirty-eight patients (13·8 per cent) developed complications. The weighted mean complication rate across the studies was 11·1 (6·0 to 16·2) per cent. Variables significantly associated with failure included preoperative radiotherapy, absence of diverting stoma, complications and male sex. Conclusion: EVT is associated with a high rate of complete healing of anastomotic leakage and stoma reversal. It is an effective option in appropriately selected patients with anastomotic leakage.

INTRODUCTION: Manual aspiration thrombectomy (MAT) and stent retriever mediated aspiration thrombectomy (SMAT) are well described reperfusion strategies for large vessel occlusions. This study aims to identify predictors of successful crossover to SMAT after failed first pass MAT. METHODS: Prospectively collected data for patients with acute large vessel occlusions undergoing thrombectomy over a 23 month period at a comprehensive stroke center were reviewed. The primary outcome was successful removal of the index clot with resultant Thrombolysis in Cerebral Infarction 2b or greater reperfusion at any point after a failed initial MAT attempt, and multivariate logistic regression analyses were performed to determine predictors of successful crossover to SMAT. RESULTS: Of 433 large vessel thrombectomies, 319 underwent first pass MAT, and 113 patients required a repeated pass for the index thrombus. Second pass MAT was performed in 77% of cases and was successful in 54%; second pass SMAT was performed in 23% of cases and was successful in 73% (P=0.11). Third pass MAT was employed in 45% of cases and was successful in 43% while SMAT was performed in 55% of cases and was successful in 77% (P=0.03). Overall, 12% of patients undergoing MAT on the first pass crossed over to successful SMAT. Predictors of successful crossover were internal carotid artery (ICA) location and higher presenting National Institutes of Health Stroke Scale (NIHSS) score. CONCLUSION: After failed first pass MAT, subsequent passes with SMAT had higher rates of successful index clot removal; patients with a higher initial NIHSS score and ICA clot location should be considered for early crossover or even initial SMAT for their clots.

Aims: The aims of this study were to establish whether composite fixation (rail-plate) decreases fixator time and related problems in the management of patients with infected nonunion of tibia with a segmental defect, without compromising the anatomical and functional outcomes achieved using the classical Ilizarov technique. We also wished to study the acceptability of this technique using patient-based objective criteria. Patients and Methods: Between January 2012 and January 2015, 14 consecutive patients were treated for an infected nonunion of the tibia with a gap and were included in the study. During stage one, a radical debridement of bone and soft tissue was undertaken with the introduction of an antibiotic-loaded cement spacer. At the second stage, the tibia was stabilized using a long lateral locked plate and a six-pin monorail fixator on its anteromedial surface. A corticotomy was performed at the appropriate level. During the third stage, i.e. at the end of the distraction phase, the transported fragment was aligned and fixed to the plate with two to four screws. An iliac crest autograft was added to the docking site and the fixator was removed. Functional outcome was assessed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. Patient-reported outcomes were assessed using the Musculoskeletal Tumor Society (MSTS) score. Results: The mean age of patients was 38.1 years (sd 12.7). There were 13 men and one woman. The mean size of the defect was 6.4 cm (sd 1.3). the mean follow-up was 33.2 months (24 to 50). The mean external fixator index was 21.2 days/cm (sd 1.5). The complication rate was 0.5 (7/14) per patient. According to the classification of Paley, there were five problems and two obstacles but no true complications. The ASAMI bone score was excellent in all patients. The functional ASAMI scores were excellent in eight and good in six patients. The mean MSTS composite score was 83.9% (sd 7.1), with an MSTS emotional acceptance score of 4.9 (sd 0.5; maximum possible 5). Conclusion: Composite fixation (rail-plate) decreases fixator time and the associated complications, in the treatment of patients of infected nonunion tibia with a segmental defect. It also provides good anatomical and functional results with high emotional acceptance. Cite this article: Bone Joint J 2018;100-B:1094-9.

Long-construct fixations can be complicated by proximal junctional kyphosis. In elderly, high-risk patients with numerous comorbidities, lengthy surgical times and increased blood loss associated with revision osteotomies and extension of fusions are not often tolerated and pose serious life-threatening risks. We present a salvage technique used in a patient with proximal junctional failure and demonstrate its role in improving symptoms and functionality in those not deemed fit for major surgery. Pre- and postoperative pain scores in accordance with the visual analogue scale, walking distances and radiographs were reviewed in a patient who underwent the salvage technique to ascertain the subjective and objective difference in pain and functionality. The patient showed marked improvement in pain scores and walking distances postoperatively. Additionally, the degree of proximal junctional kyphosis was lower on postoperative radiographs. While holding risks of its own, our described technique can be performed in select cases and is a good salvage procedure in high-risk patients. It prevents their exposure to the risks that accompany large revision operations and fusion models with further potential to fail. We recommend that our technique is performed only at specialist centres.

Survival of myeloma patients has greatly improved with the use of autologous stem cell transplantation and novel agents, such as proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies. Compared to bortezomib- and lenalidomide-based regimens alone, the addition of high-dose melphalan followed by autologous transplantation significantly improves progression-free survival, although an overall survival benefit was not observed in all trials. Moreover, follow up of recent trials is still too short to show any difference in survival. In the light of these findings, novel agent-based induction followed by autologous transplantation is considered the standard upfront treatment for eligible patients (level of evidence: 1A). Post-transplant consolidation and maintenance treatment can further improve patient outcome (1A). The availability of several novel agents has led to the development of multiple combination regimens such as salvage treatment options. In this context, the role of salvage autologous transplantation and allotransplant has not been extensively evaluated. In the case of prolonged remission after upfront autologous transplantation, another autologous transplantation at relapse can be considered (2B). Patients who experience early relapse and/or have high-risk features have a poor prognosis and may be considered as candidates for clinical trials that, in young and fit patients, may also include an allograft in combination with novel agents (2B). Ongoing studies are evaluating the role of novel cellular therapies, such as inclusion of antibody-based triplets and quadruplets, and chimeric antigen receptor-T cells. Despite encouraging preliminary results, longer follow up and larger patient numbers are needed before the clinical use of these novel therapies can be widely recommended.

AIMS: Following the resection of an extensive amount of bone in the treatment of a tumour, the residual segment may be insufficient to accept a standard length intramedullary cemented stem. Short-stemmed endoprostheses conceivably have an increased risk of aseptic loosening. Extra-cortical plates have been added to minimise this risk by supplementing fixation. The aim of this study was to investigate the survivorship of short-stemmed endoprostheses and extra-cortical plates. PATIENTS AND METHODS: The study involved 37 patients who underwent limb salvage surgery for a primary neoplasm of bone between 1998 and 2013. Endoprosthetic replacement involved the proximal humerus in nine, the proximal femur in nine, the distal femur in 13 and the proximal tibia in six patients. There were 12 primary (32%) and 25 revision procedures (68%). Implant survivorship was compared with matched controls. The amount of bone that was resected was > 70% of its length and statistically greater than the standard control group at each anatomical site. RESULTS: The mean follow-up was seven years (one to 17). The mean length of the stem was 33 mm (20 to 60) in the humerus and 79 mm (34 to 100) in the lower limb. Kaplan-Meier analysis of survival of the implant according to anatomical site confirmed that there was no statistically significant difference between the short-stemmed endoprostheses and the standard stemmed controls at the proximal humeral (p = 0.84), proximal femoral (p = 0.57), distal femoral (p = 0.21) and proximal tibial (p = 0.61) sites. In the short-stemmed group, no implants with extra-cortical plate osseointegration suffered loosening at a mean of 8.5 years (range 2 to 16 years). Three of ten (30%) without osseointegration suffered aseptic loosening at a mean of 7.7 years (range 2 to 11.5 years). CONCLUSION: When extensive resections of bone are required in the surgical management of tumours, and in revision cases, the addition of extra-cortical plates to short medullary stems has shown non-inferiority to standard length medullary stems and minimises aseptic failure.

Surgical methods for type II odontoid fracture can be classified into 2 main groups: anterior or posterior approach. A more effective way to achieve bone fusion with the lowest possible surgical risk is needed. Therefore, the aim of our study was to describe and evaluate a novel technique, cable-dragged reduction/cantilever beam internal fixation for the treatment of type II odontoid fracture.This was a retrospective study enrolled 34 patients underwent posterior cable-dragged reduction/cantilever-beam internal fixation surgery. Medical records, rates of reduction, the location of the instrumentation and fracture healing during follow-up were analyzed. Once fracture healing was obtained, instrumentation was removed. Neck pain (scored using a visual analog scale [VAS]), neck stiffness, patient satisfaction, and neck disability index (NDI) were recorded before and after removing the instrumentation during follow-up.The mean duration of follow up was 22.8â±â5.3 months. There was no iatrogenic damage to nerves or blood vessels. Radiographic evaluation showed complete reduction in the 20 patients with fracture displacement and satisfactory fracture healing in all 34 cases. Titanium cable breakage was observed in 4 patients after fracture healing. After removal of instrumentation, significant improvements were seen in neck-pain VAS score, neck stiffness, patient satisfaction, and NDI (all Pâ<â.01).Posterior cable-dragged reduction/cantilever-beam internal fixation was an optimal salvage maneuver to conventional surgical methods such as anterior screw fixation and C1-C2 screw-rod system. The operative difficulty and incidence of nerve and vascular injury were reduced. Its major disadvantage is the exposure and screw-setting at C3, which is left intact in traditional surgery, and it is suitable only for patients with intact C1 posterior arches.

Tibiotalocalcaneal arthrodesis is an effective salvage procedure in cases of combined ankle and subtalar osteoarthritis as well as severe multiplanar deformities and severe joint destruction of the hindfoot. Special mention should be made of this procedure in cases of bone loss, especially from the talus, secondary to failed previous surgeries or bone infection, often being the only way to achieve a stable and painless foot and ankle. We present a case of ankle fracture in a patient with associated morbidity and multiple complications following osteosynthesis, in which tibiotalocalcaneal arthrodesis with cemented with antibiotic coated retrograde nail has achieved a satisfactory final result.

INTRODUCTION: Burst stimulation, as described by DeRidder, is a novel waveform made up of closely spaced, high-frequency electrical impulses delivered in packets, which are followed by a quiescent period or interburst interval. Electrically generated burst waveforms were initially designed to treat neural pathology in the auditory cortex and were later applied to the spinal cord through spinal cord stimulation (SCS) devices to treat chronic pain states. When Burst stimulation is applied to the spinal cord, the impulses travel to the thalamus and then diverge, targeting both the somatosensory cortex and the limbic system where they treat both the sensory, affective and attentional components of neuropathic pain. Areas covered: Literature examining clinical and basic research findings with the application of Burst stimulation to pathologically active central neural tissue was found using bibliographic databases including PubMed, Medline, Cochrane, Embase and Google Scholar. Expert commentary: Burst stimulation offers a salvage strategy for failed tonic spinal cord stimulation (tSCS), thus improving both quality of life and cost-effectiveness of SCS by reducing explant rates. The goal of this therapy is to use more than one waveform in the same device so that lost efficacy from tSCS can be salvaged.

The treatment options for high risk acute pulmonary embolism (PE) patients with failed systemic thrombolytic treatment (STT) is limited. The clinical use of catheter directed thrombolysis with the EkoSonic Endovascular System (EKOS) in this population has not been evaluated before. Catheter directed thrombolysis is an effective treatment modality for high risk PE patients with failed STT. Thirteen consecutive patients with failed STT were included in the study. EKOS catheters were placed and tissue plasminogen activator (t-PA) in combination with unfractionated heparin were given. Clinical and echocardiographic properties of the patients were collected before EKOS, at the end of EKOS and during the follow-up visit 6 months after discharge. The duration of EKOS treatment was 21.8 ± 3.8 h and the total dose of tPA was 31.2 ± 15.3 mg. One patient who presented with cardiac arrest died and the clinical status of the remaining subjects improved significantly. Any hemorrhagic complication was not observed. EKOS resulted in significant improvement of right ventricular functions and decrease of systolic pulmonary artery pressure. During a follow-up period of 6 months none of the patients died or suffered recurrent PE. In addition, echocardiographic parameters or right ventricular function significantly got better compared to in-hospital measurements. EKOS is an effective treatment modality for high risk PE patients with failed STT and can be applied with very low hemorrhagic complications.

BACKGROUND: Implant-based breast reconstructions can result in unsatisfactory results requiring surgical revision or salvage reconstructive surgery with autologous tissue. This study compares the outcomes and complications of salvage (tertiary) flap reconstruction after failed prosthesis placement to those of primary/secondary flap reconstruction. METHODS: All patients undergoing free flap breast reconstruction after failed prosthesis between July 1, 2005, and June 30, 2014, were identified. A matched number of patients who underwent a de novo free flap breast reconstruction were selected randomly for review. The indication for prosthesis removal, demographic and operative data, flap type and inset, and complication rates were evaluated. RESULTS: Eighty-nine women with a history of failed implant-based reconstruction required free flap reconstruction for salvage in 121 breasts. Capsular contracture was the most common indication for prosthesis removal (62.0 percent). Recipient vessel scarring was 5.23 times more likely to occur in the prior prosthesis group (p < 0.001). Alternate flap types other than deep inferior epigastric perforator and transverse rectus abdominis myocutaneous flaps were more frequently used in this cohort. Major complications requiring operative management were more common in the experimental group (17.4 percent versus 8.1 percent; p = 0.035). No difference was noted in flap loss rates, operative take back, or operative time. CONCLUSIONS: Salvage breast reconstruction with autologous tissue after failed prosthesis can be safely performed, with success rates similar to those of primary free flap breast reconstruction. However, these procedures may have increased complexity because of recipient vessel scarring, higher rates of prior radiation therapy, and major complications, which may warrant appropriate preoperative planning and patient counseling. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Subsidence of the talar component results in significant morbidity after total ankle replacement. When recognized, prompt revision could be needed to preserve the function of the implant; however, this is not always the case. In situations in which the implant cannot be revised, tibiotalocalcaneal arthrodesis might be necessary to salvage the extremity. The purpose of the present report is to describe the use of a custom titanium alloy truss to fill a bony void created by explantation of the implant components. Total ankle replacement was performed as the initial surgery to address end-stage osteoarthritis. Two years after the index procedure, the patient underwent revision of the polyethylene and talar components with subtalar arthrodesis secondary to progressive subtalar osteoarthritis and talar subsidence. The implant subsequently became infected and was removed. The patient underwent re-implantation after the infection had resolved, but significant talar subsidence required conversion to a tibiotalocalcaneal arthrodesis with a custom titanium alloy truss and retrograde intramedullary nail. At the most recent follow-up appointment, the patient was weightbearing on a stable extremity and pain free. Radiographic examination confirmed appropriate implant alignment and evidence of bone formation throughout the titanium truss. Although our results are restricted to a single case with initial, limited follow-up data, combining sound structural mechanics with an open architecture and unique texture, the custom titanium truss appears to maintain the limb length and promote healing across a large void.
