Antegrade Approach

Background: This retrospective study investigates the efficacy and safety of the novel Celt ACD® vascular closure device (VCD) following antegrade and retrograde common femoral artery (CFA) punctures for the treatment of peripheral artery disease in a challenging patient collective (e.g. calcifications, obesity, and anticoagulation). Methods: A total of 208 VCDs (i.e. 100 antegrade and 108 retrograde) were deployed between October 2019 and December 2020 in a tertiary referral interventional radiology department. Fifty-two devices were undersized in relation to the introducer sheath (up to 2 Fr). Technical success and VCD related complications were evaluated in the immediate post procedure period and the following 24 h clinically. In 68% of cases, additional duplex ultrasound was performed prior to discharge. Results: The overall technical success rate was 97%. Technical failures following antegrade approach were due to a too acute access angle (⩾60°), rendering it impossible to pass the applicator tip through the sheath lumen. A subgroup analysis of technical success pinpoints severe calcification as another key limiting factor in VCD use ( p = 0.004). Comparing equally sized with undersized device selection ( p = 0.196), direction of approach ( p = 0.265), and body mass index ( p = 0.184) proved to be insignificant. Five (2%, 5/208) major complications occurred: Four antegrade (i.e. one false aneurysm, one vessel laceration with retroperitoneal hemorrhage, two device migrations; 4%, 4/100) and one following retrograde access (i.e. >6 cm hematoma, 1%, 1/108)). Complications were successfully managed with manual compression or interventional procedures. Conclusions: The novel clip-based VCD proved to be effective with a low VCD related complication rate.

Abstract Background The novel 180° cryoballoon (CbAS180) enables semicircumferential treatment over a length of 3 cm per application. This first-in-human study evaluates its feasibility, efficacy, and safety for the treatment of Barrett’s esophagus (BE) neoplasia. Methods This multicenter study consisted of dose-finding and extension phases. Dose-finding started with the lowest dose possible (1.0 mm/s). For each dose, six patients were treated circumferentially over a 3-cm length. The dose was increased until the median BE regression was ≥ 60 % without serious adverse events (SAEs). In the extension phase, the dose was confirmed in 19 new patients. The outcomes were technical success, BE regression after one treatment, and SAEs. Results 25 patients (median Prague C0M3) were included (6 dose-finding/19 extension). In two patients, the CbAS180 could not be applied because of unstable balloon positioning. The technical success rate was 96 % (22 /23). In the six dose-finding patients, the starting dose resulted in median BE regression of 94 % (95 % confidence interval [CI] 60 %–97 %) without SAEs and was thus considered effective. Overall median BE regression was 80 % (95 %CI 60 %–90 %). Conclusion Single-session CbAS180 seems feasible, safe, and effective, and is a promising technique for the treatment of patients with BE neoplasia.

Antegrade Approach

Purpose: To evaluate the safety and effectiveness of antegrade vs crossover femoral artery access in the endovascular treatment of isolated below-the-knee (BTK) lesions in patients with critical limb ischemia (CLI). Methods: Between January 2014 and December 2015, 224 high-risk patients (mean age 75.8±9.8 years; 151 men) with CLI underwent infragenicular interventions on 292 crural vessels in 3 European vascular centers. All patients had isolated TransAtlantic Inter-Society Consensus (TASC) C (n=26) or D (n=198) BTK lesions. Primary endpoints were freedom from access-related complications and technical success comparing the antegrade vs crossover access groups. Results: Balloon angioplasty was the most used treatment modality (169 vessels, 75.4%). The technical success rate was 88.4% in the entire cohort and 88.0% in the antegrade group vs 90.4% in the crossover group (p>0.99). In all patients, the technical success rate was higher for stenotic lesions (100%) vs occlusions (85.5%, p=0.002) and in patients with TASC C BTK lesions (100%) vs TASC D (86.9%, p=0.033). The overall freedom from access-related complications was 97.8%: 99% in the antegrade group and 90.6% in the crossover group (p=0.022). Larger sheath size (5/6-F vs 4-F) was associated with a significantly higher risk for access-related complications (7.1% vs 1.1%, respectively; p=0.047). Conclusion: The present multicenter study showed high technical success and a low incidence of access-related complications in the treatment of isolated BTK lesions using either antegrade or crossover femoral access. The antegrade approach with the use of a 4-F system seems to have a significantly lower rate of access-related complications.

Abstract Introduction During subintimal angioplasty (SIA), it is not always possible to re-enter the vessel lumen due to a variety of factors. Recanalization using hydrophilic wires and catheters alone, apart from its potential technical failure, is also limited by minimal control over the re-entry point. This is frequently well beyond the point of occlusion, thus often compromising important collaterals. In order to bypass the obstruction and attain controlled re-entry into the lumen of the diseased vessel, a re-entry device (RED) may be required. This paper assesses our centre’s experience with the safety and efficacy of the Pioneer re-entry system and systematically reviews the pertinent literature. Method A single centre retrospective study of subintimal angioplasty involving the use of the Pioneer Plus intravascular guided reentry catheter was performed. Patient demographics including age, gender, risk factors, comorbidities clinical indication and complications were recorded. Lesion characteristics, including location and severity of calcification were also assessed. A systematic literature review of all reported studies where the Pioneer RED was used for iliac and lower limb revascularization was conducted by 2 of the authors using the PubMed (MEDLINE) and EMBASE databases. Results The study comprised 30 cases. Technical success was 97%. A small, quickly resolved extravasation was the only device related complication. These results are in line with the systematic review which identified 16 studies using the Pioneer RED, reporting a technical success rate of 87.4–100% (median = 100%) and complication rate of 0–25.8% (median = 0%). However, due to heterogeneity in definitions of technical success, data was not pooled.

Purpose: Osteoid osteomas are benign and nonprogressive lesions. The clinical presentation of osteoid osteoma is typical with night pain responsive to nonsteroidal anti-inflammatory agents. The typical radiological appearance is lucent nidus and adjacent reactive sclerosis. The most traditional management of osteoid osteoma is surgical removal which is associated with significant morbidity. This article aims to demonstrate our single-center experience of 55 patients with osteoid osteoma treated with percutaneous radiofrequency ablation (RFA). Methods: Fifty-five symptomatic patients who were seen at our orthopedics outpatient clinics, diagnosed with osteoid osteoma, and referred to interventional radiology department between May 2015 and April 2019 were enrolled. The nidus size, pain numeric rating scale score, and intramedullary edema diameter before and after RFA were compared. Clinical and technical success, intervention-related complications, and need for subsequent ablation were recorded. Results: Of the 55 patients, including 12 pediatric cases, 6 had atypical locations such as metatarsal, vertebra, and scapula, while 1 case had osteoid osteoma with multiple nidus. The mean age was 18.5 ± 9.6 years. Preintervention maximum nidus diameter, pain score, and edema diameter were significantly lower in postintervention measurements ( p < 0.001). Technical success rate was 98.1%, and clinical success was 96.36%. Severe complication occurred in one patient with soft tissue burn and osteomyelitis. Conclusion: This is one of the largest series of osteoid osteoma treated with RFA done in a single center with atypical cases. In conclusion, RFA is safe and effective in both pediatric and adult patients with rare complications even in challenging cases with atypical locations.

Abstract. Summary: Background: Acute embolic or thrombotic mesenteric ischaemia (AMI) is a rare but life-threatening clinical condition. Despite diagnostic and therapeutic advances, the mortality rate remains high, between 60 % and 90 %. Over the last years revascularisation was increasingly performed by endovascular techniques. The aim of this study was to retrospectively analyse the clinical outcome of catheter-directed thrombolysis (CDT) and aspiration thrombectomy (AT) in patients with AMI with regard to technical success, intervention-related complication rate, need for secondary abdominal surgery, clinical course and 30-day mortality rate. Patients and methods: Thirteen patients (4 men, 9 women; mean age 74.5 ± 17 years) with 12 embolic and one thrombotic occlusion of the superior mesenteric artery (SMA) underwent emergent endovascular revascularisation of SMA. Clinical data including all imaging reports, laboratory analysis and follow-up data were derived from the electronic patient file and images were reviewed on a Picture Archiving and Communication System. Results: Eleven patients (n = 11; 84.6 %) underwent CDT and AT, and two patients (n = 2; 15.4 %) had AT alone. Technical success with complete restoration of SMA perfusion was achieved in 38.5 % (n = 5). Adjunctive angioplasty ± stenting was mandatory in 2 patients. Overall, the intervention-related complication rate was 38.5 %. In total, 46.2 % (n = 6) clinically improved following the intervention, while 38.5 % required explorative laparotomy after the intervention, with 2 colectomies and 2 small bowel resections. Overall, the 30-day mortality rate was 30.8 %. Conclusions: Endovascular revascularisation with CDT in combination with AT is feasible, with a technical success rate of 38.5 % (n = 5). Endovascular revascularisation was beneficial for 46.2 % (n = 6) of the patients, who clinically improved following the intervention. The need for secondary explorative laparotomy was rather low, with 38.5 % (n = 5) of the patients. The 30-day-mortality remains high with 30.8 %.

Introduction: To evaluate the feasibility and safety of the Mynx vascular closure device (VCD) for arteriotomy closure after stent placement near the common femoral artery (CFA) access site. Methods: A total of 88 patients (73 men; mean age, 72 ± 9.2 years; 136 procedures) who underwent closure of CFA arteriotomy using the Mynx VCD after stent placement in proximal superficial femoral artery (SFA) with antegrade approach, or in common or external iliac artery with retrograde approach were retrospectively studied. Technical success and access site complication were evaluated. Body mass index (BMI), platelet count, international normalized ratio, prior history of ipsilateral CFA access, access direction, degree of CFA calcification, stent location and diameter, total procedure time, and sheath size were analyzed to evaluate their relationship with technical failure and development of bleeding complications. Results: Technical success was achieved in 94.9% (129/136) patients. The mean time to hemostasis was 0.7 ± 1.8 min. Technical failure was significantly associated with low BMI ( p = 0.001). Other variables presented no significant relationship with technical failure and development of complications. Ultrasonography on the day after the procedure revealed that 8 (5.9%) patients had hematoma. Conclusions: Mynx VCD for arteriotomy closure is feasible and provides hemostatic safety after stent placement near antegrade or retrograde CFA access. However, Mynx VCD may have a poor technical success rate among patients with low BMI.
