Abstract
PURPOSE To highlight median arcuate ligament syndrome as a potential cause for celiac artery stenosis and pancreaticoduodenal artery aneurysm, and describe treatment options in this setting. CASE REPORT A 63-year-old male presented with a pancreaticoduodenal artery aneurysm and concomitant celiac artery stenosis that was treated with celiac artery stenting and aneurysm coiling. He subsequently developed stent fracture and celiac artery occlusion secondary to previously unrecognized median arcuate ligament syndrome causing reperfusion of the aneurysm. This was treated with open median arcuate ligament release and aorta to common hepatic artery bypass with good clinical result and stable 20-month surveillance imaging. CONCLUSION It is critical to recognize median arcuate ligament syndrome as a cause of celiac artery stenosis in the setting of pancreaticoduodenal artery aneurysm given the high risk of failure of endovascular stenting. Open aorto-hepatic artery bypass and endovascular aneurysm coiling should be the preferred approach in these patients.

Abstract
Despite the advancements in the technique of duct stenting (DS) in patients with duct-dependent pulmonary circulation (DDPC) and the valuable role of DS in preventing the risk of surgical creation of shunts and early repair, not all ducts are amenable to being stented, and not all interventions with DS are safe and can achieve positive outcomes. Very few studies focusing on tortuous ducts have been conducted until now. Their results showed that stenting of highly tortuous ducts has the same risk as surgical options. This type of stenting has greater possibility of complications, early in-stent thrombosis, and stent failure than do other duct types. In such cases, the surgical options could be superior to DS and have better outcomes. This report aims to review the very scarce available data about stenting of high-tortuous ducts and criticisms of performing DS in ducts associated with pulmonary stenosis and to highlight the essential points that must be considered before deciding on intervention.

Abstract
BACKGROUND Myocardial revascularization failure (MRF) and Secondary revascularization (SR) are contemporary interventional cardiology challenges. AIM To investigate the characteristics, management, and prognosis of patients with myocardial revascularization failure (MRF) and need for secondary revascularization (SR) in contemporary practice. METHODS The REVASEC study is a prospective registry (NCT03349385), which recruited patients with prior revascularization referred for coronary angiography at 19 centers. The primary endpoint is a patient-oriented composite (POCE) at 1 year, including death, myocardial infarction, or repeat revascularization. RESULTS A total of 869 patients previously revascularized by percutaneous intervention (83%) or surgery (17%) were recruited. MRF was found in 83.7% (41.1% stent/graft failure, 32.1% progression of coronary disease, and 10.5% residual disease). SR was performed in 70.1%, preferably by percutaneous intervention (95%). The POCE rate at 1 year was 14% in the overall cohort, with 6.4% all-cause death. In the multivariate analysis, lower POCE rates were found in the groups without MRF (9.4%) and with disease progression (11%) compared with graft/stent failure (17%) and residual disease (18%), hazard ratio 0.67 (95% confidence interval: 0.45-0.99), p = 0.043. At 1 year, the SR group had less chronic persistent angina (19% vs. 34%, p < 0.001), but a higher rate of repeat revascularization (9% vs. 2.9%, p < 0.001). CONCLUSION MRF was found in 84% of patients with prior revascularization referred for coronary angiography. Stent/graft failure and residual coronary disease were associated with a worse prognosis. SR provided better symptom control at the expense of a higher rate of new revascularization.

Abstract
Introduction Ureteral stent obstruction hinders the management of malignant diseases. Adequate stent insertion through an obstructed ureter does not necessarily guarantee renal decompression and stent-related symptoms adversely affect patient comfort. There are two major problems associated with ureteral stents: obstruction and intolerance to the stents. Case Presentation A 45-year-old woman was treated for cervical cancer with metastatic lymph nodes and ureteral obstruction with chemotherapy, radiotherapy, immunotherapy, and bilateral retrograde stenting. After recurrent stent obstruction, stent replacement was attempted more than 18 times over two years. In addition, stent-related symptoms adversely affected patient comfort. The patient was finally fitted with Superglide 8-French reinforced ureteral stents. Their replacement every six months was viewed by the patient as a relief compared to the all too frequent replacement of the previous stents. Moreover, the customized changes in the shape of Superglide stents improved patient comfort. Discussion Recent publications tend to indicate that large-lumen ureteral stents are most likely to remain permeable over time. Various modifications of the bladder or endo-ureteral part of double-pigtail stents have been increasingly reported, with the aim of improving their tolerance while maintaining effective drainage. Conclusion Adaptation of the internal lumen and shape of stents to the characteristics of the tumor and patient measurements appears to be important for increasing the drainage and tolerance of ureteral stents. The top priority for future ureteral stents suitable for malignant diseases should be to integrate these characteristics based on state-of-the-art data.

Abstract
BACKGROUND Recurrent in-stent restenosis (ISR) remains a serious problem. Optimal modification of the underlying mechanism during index percutaneous coronary intervention (PCI) is key to prevent ISR. Excimer laser coronary atherectomy (ELCA) has its own indications and is among others used in recurrent ISR in case of stent underexpansion and/or diffuse neointimal hyperplasia. We aimed to assess the long-term clinical outcomes of ELCA for the management of recurrent ISR. METHODS A multicenter, retrospective observational study was conducted. Patients with recurrent ISR who were additionally treated with ELCA were included. The primary outcome was major adverse cardiac events (MACE) defined as a composite of cardiovascular death, myocardial infarction, stroke, target lesion revascularization at 12 months, and longer term. RESULTS Between 2014 and 2022, 51 patients underwent PCI with the additional use ELCA for recurrent ISR. Primary outcome occurred in 6 patients (11.8%) at 12 months and in 12 patients (23.5%) at a median follow-up of 4 (1-6) years. Technical and procedural success were achieved in 92% and 90% of cases, respectively. Coronary perforation occurred in 2 patients as a result of distal wire perforation, but was not ELCA-related. There were no in-hospital MACE. CONCLUSIONS ELCA appears to be a safe method with acceptable long-term results for the management of recurrent ISR.

Abstract
PURPOSE To evaluate the safety and efficacy of the placement and exchange of tandem ureteral stents (TUS) under fluoroscopic guidance in the management of indwelling single double-J stent (DJS) failure in patients with malignant ureteral obstruction. We also aimed to investigate whether the generally accepted exchange period of DJSs could be extended using TUS. METHODS This retrospective study involved 11 patients (10 female) with an age range of 27-64 years, median of 49 years, who underwent TUS (ipsilateral two 8F DJSs) placement due to indwelling single DJS failure occurring in less than 3 months. TUS exchanges were performed initially at 6-month intervals, and subsequent exchange intervals were extended to 9 and 12 months for seven patients. The interval from initial TUS placement to percutaneous nephrostomy, repeat exchange, or death was defined as the duration of stent patency. RESULTS Indwelling single DJS failure occurred during a median follow-up of 45 days (range, 35-60 days) in 14 ureters of 11 patients. TUS were successfully placed and exchanged with a technical success rate of 100% without any early major complications. Thirty-nine procedures (11 placement and 28 exchange procedures) in 55 ureters were performed. The median duration of urinary patency was significantly higher with TUS [300 days (range, 60-440 days)] compared with single DJSs [45 days (range, 35-60 days)] (P < 0.001). CONCLUSION The placement and exchange of TUS can be safely and effectively performed under fluoroscopic guidance. The need for frequent DJS exchange could be reduced with increased duration of stent patency using TUS.

Abstract
BACKGROUND Lipid-rich plaque is an important substrate that causes future coronary events. However, the clinical implications of underlying plaque characteristics in coronary lesions after newer-generation drug-eluting stent (DES) implantation remain unknown. METHODS The current study analyzed 445 target lesions after newer-generation DES implantation in 416 patients with CAD (CCS/ACS=264/181) from the REASSURE-NIRS multi-center registry. Near-infrared spectroscopy (NIRS) imaging was used to evaluate maximum lipid core burden index after stent implantation in target lesions (residual maxLCBI4mm). The primary and secondary outcomes were 3-year lesion-oriented clinical outcomes (LOCO; cardiac death, non-fatal target lesion-related MI, or ischemia-driven TLR) and patient-oriented clinical outcomes (POCO; all-cause death, non-fatal MI, or ischemia-driven unplanned revascularization). Outcomes were compared by residual maxLCBI4mm tertile. RESULTS Median residual maxLCBI4mm was 183; 16% of lesions had residual maxLCBI4mm >400. Higher residual maxLCBI4mm was not associated with a greater likelihood of LOCO or POCO during the observational period (LOCO, log-rank p=0.76; POCO, log-rank p=0.84). Mixed-effects logistic regression demonstrated that residual maxLCBI4mm does not predict LOCO (odds ratio=1.000, 95% CI=0.997-1.003, p=0.95). There was no significant relationship between residual maxLCBI4mm and POCO (odds ratio=1.001, 95% CI=0.999-1.002, p=0.30). CONCLUSIONS Residual maxLCBI4mm is not associated with LOCO or POCO in patients with CAD after newer-generation DES implantation. Our findings suggest that NIRS-derived underlying lipid-rich plaque is not associated with the risk of stent-related events and patient-based outcomes in patients with CAD who have received a newer-generation DES.

Abstract
Introduction: Management of malignant ureteral obstruction (MUO) with ureteral stents remains a clinical challenge, often involving frequent stent exchanges attributable to stent failure or other urological complications. We report our institutional experience with ureteral stents for management of MUO, including analysis of clinical factors associated with stent failure. Methods: We performed a retrospective review of patients treated with indwelling ureteral stents for MUO in nonurothelial malignancies at our tertiary-care institution between 2008 and 2019. Univariate Cox proportional hazards analysis was performed to identify clinical variables associated with stent failure and stent-related complications. Stent failure was defined as need for unplanned stent exchange, placement of percutaneous nephrostomy (PCN), or tandem stents. Results: In our cohort of 78 patients, the median (range) number of stent exchanges was 2 (0-17) during a total stent dwell time of 4.3 (0.1-40.3) months. Thirty-four patients (43.6%) developed a culture-proven urinary tract infection (UTI) during stent dwell time. Thirty-five patients (44.8%) had stent failure. Twenty-two patients (28.2%) underwent unplanned stent exchanges, 23 (29.5%) required PCN after initial stent placement, and 6 (7.7%) required tandem stents. Ten (28.6%) patients with stent failure were treated with upsized stents, which led to resolution in seven patients. Stent failure occurred with 20/44 (45.4%) Percuflex™, 15/27 (55.6%) polyurethane, and 2/3 (66.7%) metal stents. In patients with ≥2 exchanges (N = 45), median time between exchanges was 4.1 (2.0-14.8) months. Bilateral stenting and history of radiation predicted UTI development. Median overall patient survival after initial stent placement was 19.9 months (95% CI 16.5-37.9 months). Conclusions: Ureteral stent failure poses a significant medical burden to patients with MUO. Better methods to minimize stent-related issues and improve patient quality of life are needed. Using a shared decision-making approach, clinicians and patients should consider PCN or tandem stents early in the management of MUO.

Abstract
Introduction Ureteral obstruction hinders the management of malignant diseases. Adequate stent placement does not necessarily guarantee renal decompression. The stent stiffness may play a major role to maintain patency. We carried out the present study in order to evaluate drainage efficiency by using stents with distinctive degrees of stiffness and to identify the physical factors that could prevent obstruction of the stent in patients with malignant ureteral obstruction (MUO). Materials and Methods We performed an analysis of 150 patients with MUO drainage at a single institution from June 2009 to June 2019. A progressive choice of stents was shaped to overcome each failure by focusing on the criterion of increasingly stiff stents. Results During the study period, 556 ureteral stent procedures (USP) were analysed separately. The stent failure with obstruction occurred in 23.0% (128/556) of USP at a mean of 4.4±3.6 months and depended on the type of stent. Stent failure occurred in 34.2% (70/205) of Vortek® stents, in 42.9% (15/35) of Urosoft stents, in 15.4% (39/254) of Superglide or ureteral catheters and in 6.5% (4/62) of tandem stents. No significant differences were found between Vortek® and Urosoft stents regarding stent failures, but there were significant differences between Superglide or Tandem stents and Vortek® or Urosoft stents (p<10−7). The study demonstrated that ureteral stent obstruction significantly decreased with a larger lumen or a stiffer stent (p<10−7). Conclusion In the present study, Superglide and tandem stents were the best stents against stent failure, and the lumen and the stiffness of the stent have been shown to be critical factors in controlling patency. The results suggest that the lumen seems more important than the stiffness, and the stiffness would be the only means of keeping the lumen intact. Future stents for MUO should integrate the importance of the lumen of the stent.

Abstract
Longitudinal stent deformation is defined as shortening or elongation of the stent along its longitudinal axis after deployment. It is under-recognized on angiography, and imaging- based studies have reported an incidence of up to 1%. The etiology includes damage by the guiding catheter or secondary devices such as postdilation balloons, imaging catheters, additional stents, or wire entanglement. Deformation can occur with all stent platforms. In the present case, forceful removal of the trapped guidewire led to the guide being sucked into the LAD and deforming the stent.

Abstract
The occurrence of in-stent restenosis (ISR) still remains a daunting challenge in the current era, despite advancements in coronary intervention technology. The authors explore the underlying pathophysiology and mechanisms behind ISR, and describe how the use of different diagnostic tools helps to best elucidate these. They propose a simplistic algorithm to manage ISR, including a focus on how treatment strategies should be selected and a description of the contemporary technologies available. This article aims to provide a comprehensive outline of ISR that can be translated into evidence-based routine clinical practice, with the aim of providing the best outcomes for patients.
