Project description:BackgroundIn recent years, the retrograde approach has become a common practice in the treatment of chronic total occlusion (CTO) of coronary ostium which is arising abnormally and has an ambiguous proximal cap. In this case report, we report a case of retrograde percutaneous coronary intervention (PCI) done successfully on an abnormally originating artery which was guideliner assisted. Case Presentation. A 65-year-old gentleman with a history of hypertension, diabetes, and PCI presented to us with angina. Physical examination, electrocardiography (ECG), and echocardiography were done. Coronary angiography (CAG) revealed a normal left anterior descending artery (LAD), an anomalous circumflex (CX) artery arising from the right cusp. The abnormal CX had an implanted stent from which the abnormal right coronary artery (RCA) was arising and had a CTO. It also revealed the retrograde filling of distal RCA through grade 2 Werner collateral channels (CCs) from the LAD, a long CTO segment with a distal cap at the bifurcation. PCI of an RCA-CTO was scheduled utilizing a primary retrograde strategy, since antegrade ostium was abnormal in origin, and the patient was previously stented across the origin. The retrograde wire was externalized, and the procedure was completed with 3 overlapping drug-eluting stents (DESs). We used a guideliner which also assisted in the capture of retrograde corsair during the retrograde procedure of CTO [assisted reverse controlled antegrade and retrograde tracking (CART)]. These measures helped us to complete the CTO intervention successfully.ConclusionThe antegrade crossing is the most common approach to CTOs. However, it is sometimes difficult to penetrate the proximal hard ambiguous cap with guidewires, especially in the case of CTOs of anomalous coronary arteries because of a lack of support. Herein, we describe an iteration of reverse CART technique using a guide extensor catheter to facilitate externalizing the retrograde wire from false to true lumen.

Project description:BackgroundRobot-assisted radical prostatectomy (RARP) with extended lymphadenectomy (ePLND) is the gold standard for surgical treatment of prostate cancer (PCa). Recently, the en-bloc ePLND has been proposed but no studies reported on the standardization of the technique. The aim of the study is to describe different standardized en-bloc ePLND, the antegrade and the retrograde ePLND, and to compare their surgical and oncological outcomes.Materials & methodsFrom January 2018 to September 2019, all patients subjected to RARP plus ePLND by one single surgeon were enrolled. ePLND was performed in a retrograde fashion by starting laterally to the medial umbilical ligament from the internal inguinal ring proceeding towards the ureter, or in an antegrade way by starting from the ureter at its crossing with the common iliac artery and proceeding towards the femoral canal. Patients' demographic data, clinical and surgical data were collected. Each en-bloc ePLND was categorized as "efficient" or "inefficient" by the operator, as surrogate of surgeon's satisfaction.ResultsAntegrade and retrograde ePLND were performed in 41/105 (group A) and 64/105 (group R) patients, respectively. The two groups (A vs R) had similar median (IQR) number of lymph nodes retrieved [20 (16.25-31.5) vs 19 (15-26.25); p = 0.18], ePLND time [33.5 (29.5-38.5) min vs 33.5 (26.5-37.5) min; p = 0.4] and post-operative complications [8/41 (19.5%) vs 9/64 (14.1%); p = 0.61]. In group A, 3/41 (7.3%) clinically significant lymphoceles were reported, while 1/64 (1.6%) in group R (p = 0.3). 33/41 (80.5%) and 28/64 (44%) procedures were scored as efficient 59 in group A and R, respectively (p = 0.01). On multivariate regression, only BMI (B = 0.93; 95% CI 0.29-1.56; p = 0.005) was associated with a longer ePLND time.ConclusionsThe study indicates that antegrade and retrograde en-bloc extended pelvic lymph node dissection (ePLND) have comparable surgical and oncologic outcomes, supporting the importance of standardizing the procedure rather than focusing on the direction. Although both techniques aligned with current evidence regarding lymph node invasion and complications, the antegrade approach was subjectively perceived as safer due to early isolation of critical anatomical landmarks. Encouragement for the use of en-bloc ePLND, regardless of direction, is emphasized to improve prostate cancer staging accuracy and procedural standardization.

Project description:New interventional techniques have made transcatheter closure of aortic paravalvular leaks a viable therapeutic option to treat the sequelae of these defects, including congestive heart failure and hemolysis. We report the transcatheter closure of an aortic paravalvular leak via a combined retrograde/antegrade approach. This was necessary because of difficulty in crossing the defect with a sheath from the retrograde approach. This technique might be useful in application to other difficult structural heart interventions. To our knowledge, this is the first report of a treated paravalvular leak around a Mitroflow(®) Aortic Pericardial Heart Valve.

Project description:Background and purposeAngioplasty and stenting of the subclavian artery have been reported with high technical and clinical success rates, low complication rates, and good midterm patency rates. Different antegrade or retrograde endovascular catheter-based approaches are used. Nowadays, endovascular therapy has taken over open surgical techniques in subclavian artery disease. The purpose of this study was to determine safety, efficacy, and midterm clinical and radiological outcome of the endovascular treatment with special focus on the different technical approaches in subclavian artery disease.Materials and methodsBetween 2014 and 2017, 11 patients (10 men, 1 woman) with symptomatic high-grade stenosis (90%-100%) of the subclavian artery were treated with endovascular treatment. Their mean age was 51.3 years (range, 32-61 years). Mean angiographic and clinical follow-up was 22.5 months (range, 5-44 months). Clinical follow-up was performed at hospital discharge and routine follow-up was performed at 1, 3, 12 months, and 6 monthly thereafter. In all 11 patients, a percutaneous approach was used successfully. In eight patients, the lesions were accessed retrogradely through a brachial artery puncture.ResultsAcute success rate was 100%. There were no significant peri-procedure complications. At the latest clinical follow-up (mean of 22.5 months), all patients showed a good outcome with a restenosis rate of 18.2% including a patient with Takayasu arteritis.ConclusionPercutaneous antegrade and retrograde stenting of high-grade subclavian artery stenosis is a viable less invasive alternative to open bypass surgery with good midterm clinical results and patency rates.

Project description:Evidence comparing ultrasound endoscopy-guided fine-needle biopsy (EUS-FNB) with EUS-guided fine-needle aspiration (EUS-FNA) in deep-seated lymphoma tissue sampling is insufficient. This study aims to evaluate the diagnostic efficacy of immunohistochemistry (IHC) or flow cytometry (FCM) on specimens obtained from EUS-FNB and EUS-FNA in the diagnosis and staging of deep-seated lymphomas. This real-world, dual-center study prospectively evaluated all eligible specimens from patients who underwent EUS-FNB/FNA over an 8-year period. 53 patients were enrolled, with 23 patients in the EUS-FNB group and 30 patients in the EUS-FNA group. FNB yielded specimens with longer core tissues (0.80 mm [0.55, 1.00] vs. 0.45 mm [0.30, 0.50], p = 0.009) and higher scores of specimen adequacy [4 (3.75, 4.00) vs. 3 (1.00, 4.00), p = 0.025]. Overall analysis revealed that the diagnostic accuracy of IHC based on specimens acquired from EUS-FNB was significantly higher than that of EUS-FNA (91.30% vs. 60.00%, p = 0.013). After controlling confounding factors including lesion size and endoscopists, EUS-FNB with IHC maintained a higher-level diagnostic accuracy compared to EUS-FNA (OR = 1.292 [1.037-1.609], p = 0.023). When FCM was additionally used to analyze the specimen acquired from EUS-FNA, the diagnostic yield was significantly improved (ROC AUC: 0.733 vs. 0.550, p = 0.015), and the AUC of FNB alone or combined with FCM was 0.739 and 0.761. Conclusions: FNB needles generate higher histopathological diagnostic accuracy and specimen quality than FNA for the deep-seated lymphoma. Though the application of FCM significantly improves the diagnostic efficacy of EUS-FNA, FNB was still the preferred diagnostic modality with a shorter procedure time, comparable diagnostic accuracy, and better cost-effectiveness.

Project description:BackgroundStenosis resulting in dysfunctional dialysis access may occur simultaneously on the anastomotic and central venous side. The purpose of this study was to retrospectively evaluate the feasibility of a single sheath inverse technique using the vertical puncture approach to perform bidirectional transvenous percutaneous transluminal angioplasty (PTA) from a single sheath for such dialysis access stenoses.Materials and methodsTwenty patients (26 cases; 13 males; median age, 74 [range: 50-89] years) who underwent PTA using the sheath inverse technique for dysfunctional arteriovenous fistula stenoses between April 2019 and June 2023 were included. All procedures were performed in an outpatient setting. A 4-cm sheath (4Fr, four cases; 5Fr, 19 cases; 6Fr, three cases) was inserted by vertical puncture through a cutaneous vein in the forearm (20 cases) or upper arm (six cases). After treating one side of the lesion, the sheath was reversed to treat the lesion on the opposite side. The vessel diameter at the sheath insertion site, the success rate of sheath inversion, the number of PTA balloon catheters used, the PTA success rate, adverse events, and primary and secondary patency rates up to one year after PTA were evaluated.ResultsThe median diameter at the sheath indwelling site was 5.2 (range: 3.6-9.5) mm, and sheath inversion was successful in all cases, eliminating the need to place an additional sheath at another site for contralateral stricture treatment. The number of balloon catheters used was one and two in 17 (65%) and eight cases (31%), respectively, and three in one case wherein a drug-coated balloon was used. PTA was successful in all cases and major complications were not observed. However, in one case wherein a sheath had to be placed at the arterial needle puncture site, the skin was hard, leading to difficulty in inversion, and transient venous spasm occurred post-inversion. The primary patency rates at 3, 6 and 12 months after the PTA were 87.5%, 41.7%, and 20.8%, respectively. The secondary patency rates at 6 and 12 months were 100% and 75%, respectively.ConclusionThe single-sheath inverse technique for arteriovenous fistulas was feasible without sheath withdrawal.

Project description:The purpose of this study is to analyze outcomes of combined antegrade-retrograde dilations (CARD). This retrospective study was conducted on 14 patients with a history of head and neck cancer, treated with radiation therapy that was complicated by either complete or near-complete esophageal stenosis. All patients had minimal oral intake and depended on a gastrostomy tube for nutrition. Swallow function before and after CARD was assessed using the Functional Oral Intake Scale, originally developed for stroke patients and applied to head and neck cancer patients. Patients undergoing CARD demonstrated a quantifiable improvement in swallow function (p = 0.007) that persisted at last known follow-up (p = 0.015) but only a minority (23.1%) achieved oral intake sufficient to obviate the need for tube feeds. Complication rates were 24% per procedure or 36% per patient, almost all complications required procedural intervention, and all complications occurred in patients with complete stenosis. Our study suggests further caution when considering CARD, careful patient selection, and close post-operative monitoring.
