Single suture-mediated closure system after transfemoral transcatheter aortic valve implantation: A single-center real-world experience.

BACKGROUND: Despite the use of two crossed Perclose ProGlide™ (Abbott Vascular Devices) is the most widespread technique to close the main arterial access in transfemoral transcatheter aortic valve implantation (TF-TAVI), the safest and most effective strategy still remains much debated. AIMS: The aim of the present study was to evaluate the performance of a single Perclose ProGlide suture-mediated closure device to obtain femoral hemostasis after sheathless implantation of self-expanding transcatheter heart valves through their 14 F-equivalent fix delivery systems. METHODS: This prospective observational study included 439 patients undergoing TF-TAVI at the "Montevergine" Clinic of Mercogliano, Italy. All patients underwent hemostasis of the large-bore access using a single Perclose ProGlide with preclose technique, after sheathless implantation of self-expanding transcatheter heart valves through 14 F-equivalent fix delivery systems. A multidetector computed tomography analysis of size, tortuosity, atherosclerotic, and calcification burdens of the ilio-femoral access route was made by a dedicated corelab. Vascular complications (VCs), percutaneous closure device (PCD) failure, and bleedings were adjudicated by a clinical events committee. RESULTS: A total of 81 different VCs were observed in 60 patients (13.7%); among these, 41 (5% of patients) were categorized as major. PCD failure occurred in 14 patients (3.2%). At the logistic regression analysis, no predictors of PCD failure have been identified. CONCLUSION: This registry suggests that the use of a single suture-mediated closure device could be considered a safe and efficient technique to achieve access site hemostasis in patients undergoing TF-TAVI through 14 F-equivalent fix delivery systems.

Ambulatory pulmonary vein isolation workflow using the Perclose ProglideTM suture-mediated vascular closure device: the PRO-PVI study.

AIMS: The leading reason for delayed discharge after pulmonary vein isolation (PVI) is vascular complications. This study aimed to evaluate feasibility, safety, and efficacy of the Perclose Proglide™ suture-mediated vascular closure in ambulatory PVI, report complications, patient satisfaction, and cost of this approach. METHODS AND RESULTS: Patients scheduled for PVI were enrolled prospectively in an observational design. Feasibility was assessed as % discharged the day of procedure. Efficacy was analysed as acute access site closure rate, time to reach haemostasis, time to ambulate, and time to discharge. Safety analysis consisted of vascular complications at 30 days. Cost analysis was reported using direct and indirect cost analysis. A 1:1 propensity matched control cohort was used for comparing time to discharge to usual workflow. Of 50 enrolled patients, 96% were discharged on the same day. 100% of devices were successfully deployed. Immediate (<1 min) haemostasis was reached in 30 patients (62.5%). Mean time to discharge was 5:48 ± 1:03 h (vs. 10:16 ± 1:21 h in the matched cohort, P < 0.0001). Patients reported high level of satisfaction with the post-operative time. No major vascular complication occurred. Cost analysis showed a neutral impact compared to the standard of care. CONCLUSION: The use of the closure device for femoral venous access after PVI led to safe discharge of patients within 6 h from the intervention in 96% of the population. This approach could minimize the overcrowding of healthcare facilities. The gain in post-operative recovery time improved patients' satisfaction and balanced the economic cost of the device.

Efficacy and safety of Proglide use and early discharge after atrial fibrillation ablation compared to standard approach. PROFA trial.

BACKGROUND AND OBJECTIVES: The common practice after atrial fibrillation ablation is to admit patients for an overnight stay. The aim of this study was to compare a strategy of vascular suture mediated closure system utilization and early discharge (strategy A) compared to traditional closure and overnight hospitalization (strategy B) regarding feasibility, safety, quality of life and health care cost effectiveness. METHODS AND RESULTS: Hundred patients were randomized to compare both strategies. No clinical differences were reported except diabetes mellitus. Six patients (6%) had and emergency visit or were admitted in the first 30 days after procedure. Three occurred in strategy A versus three in strategy B (p = 1) (p < .005 for non-inferiority). Forty out of 50 patients (80%) were safely discharged in a time frame of 3 h and 42 patients (84%) were discharged in the same day of the procedure in strategy A. Time to discharge was shorter in strategy A compared to strategy B. (5.89 ± 7.47 h vs. 27.09 ± 2.29 p < .005). No differences were obtained in quality-of-life outcomes. Mean (95% CI) euros cost saving per patient in strategy A was 379.16 ± 93.55 p < .001. Ten acute complications (10% patients CI 95% 4.02%-15.98%) were reported during the trial. Seven (14% CI 95% 4.04%-23.96%) occurred in strategy A patients versus 3 (6% CI 95% 0.8%-12.8%) in strategy B. (p = .182) CONCLUSION: A strategy of vascular suture mediated closure system utilization and early discharge was feasible, reduced time to discharge, saved costs and was not associated with more complications or admissions/emergency visits in a 30-day time frame after procedure compared to a strategy of regular admission and discharge after overnight stay. There were no differences regarding quality-of-life parameters between both strategies.

Treatment of inadvertent cervical arterial catheterization: Single-center experience.

OBJECTIVES: Inadvertent arterial catheterization can occur during transjugular central venous catheter insertion and should be promptly treated to prevent serious consequences. Although many treatment modalities are available, no exist guidelines regarding the selection of treatment. We aimed to describe our experience with the treatment of 11 patients who underwent inadvertent cervical arterial catheterization and propose an algorithm for the selection of treatment methods. METHODS: We retrospectively identified all patients who were treated for inadvertent arterial catheterization at our center between January 2016 and March 2021. We reviewed patient profiles, images, treatment methods, and follow-up data. RESULTS: Eleven patients were included (eight men and three women, age: 36-73 years). Ten catheter misplacements were in the right common carotid artery. The remaining catheter was inserted into the right subclavian artery after penetrating the right common carotid artery. Two catheters were 5-Fr and nine catheters were 11.5-Fr. Two patients underwent manual compressions, three underwent open surgery, three underwent stent-graft repairs, and four underwent Perclose Proglide closure. Clinical success was achieved in all 11 patients. Primary technical success was achieved in 10 patients. In one patient, unsuccessful manual compression was followed by successful stent-graft repair; the manual compression failed to prevent bleeding, possibly because of the long-term oral administration of aspirin for coronary heart disease. The mean follow-up was 5.4 months (range, 1-12 months). The overall mortality rate was zero, and no vascular or neurological events occurred. CONCLUSIONS: The existing data show that the current protocol for the treatment of inadvertent cervical arterial catheterization at our center is safe and effective. However, the data are insufficient and require further clinical validation.

Percutaneous VA-ECMO from Cannulation to Decannulation: Novel Use of a Vascular Closure Device in Pediatrics.

VA-ECMO can be lifesaving in cardiogenic shock in children. While surgical vascular repair is the current standard of care for decannulation, it comes with notable risks. We present a series of eight patients who underwent decannulation with a collagen plug-based vascular closure device (MANTA) for the common femoral artery. Seven of the patients were successfully decannulated without access site-related vascular complications. One required conversion to surgical cut-down with arterial repair due to device failure. This series demonstrates the successful use of the MANTA device in percutaneous VA-ECMO decannulation in the pediatric population, while highlighting potential technical challenges for success.

Outcomes comparison between percutaneous decannulation with perclose ProGlide and surgical decannulation of veno-arterial extracorporeal membrane oxygenation.

OBJECTIVE: Our study aimed to compare the decannulation-related outcomes of two different decannulation methods in patients who underwent veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support, namely percutaneous decannulation with Perclose ProGlide device and conventional surgical repair. BACKGROUND: Surgical vascular repair is a standard strategy when ECMO is to be terminated and sometimes associated with severe complications. Percutaneous decannulation using Perclose ProGlide has been reported to be feasible and safe in selected patients, but there is a paucity of literature to make systematic comparisons between the two decannulation methods. METHODS: 41 patients who were supported with VA-ECMO for refractory cardiogenic shock, cardiac arrest, or escort of complex interventions from December 2018 to December 2021 were enrolled. Of these, 30 underwent percutaneous Perclose ProGlide decannulation and 11 underwent surgical repair. The clinical characteristics and complication rates were analyzed. RESULTS: Patients in the two groups showed a similar incidence of vascular-related complications, such as acute lower limb ischemia, major bleeding, severe hematoma, pseudoaneurysm, and arteriovenous fistula [20% versus 18.2%, p=.896]. The incidence of groin infection and delayed healing was significantly higher in the surgical removal group [3.3% versus 36.4%, p=.014]. CONCLUSIONS: Percutaneous decannulation of veno-arterial extracorporeal membrane oxygenation with the Perclose ProGlide device is a feasible and safe technique that simplifies the decannulation process, shortens the hospitalization duration, and lowers the potential risk of groin infection and delayed wound healing.

An Effective Method for Percutaneous Removal of Venoarterial Extracorporeal Membrane Oxygenation by a Combination of Balloon Dilatation in Endovascular Therapy and the Perclose Proglide™ Closure Device.

BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) can be undertaken surgically, but there are various problems with this method. METHODS AND CASE REPORT: We removed the arterial cannula of VA-ECMO percutaneously by combining intravascular balloon dilatation and the Perclose ProGlide™ (PP) closure device in a short amount of time and the extent of bleeding was extremely small. Simultaneously, the venous cannula was removed by suturing and manual compression. We report a series of cases of percutaneous removal of VA-ECMO using intravascular balloon dilatation and PP. CONCLUSIONS: By using this method, VA-ECMO removal was possible in a very short amount of time with minimal invasiveness.

A systematic review of vascular closure devices for femoral artery puncture sites.

OBJECTIVE: The aim of this review was to provide an up-to-date summarization of available Food and Drug Administration-approved vascular closure devices (VCDs) and to analyze current evidence comparing individual devices with one another and with manual compression (MC). The review includes indications for use, advantages and disadvantages, safety and efficacy, and outcomes. METHODS: A review of literature available on VCDs was conducted using PubMed and MEDLINE. Only clinical trials published within the last 10 years evaluating the efficacy of different VCDs with access obtained through common femoral artery or vein were included. All literature included in this review was published in English and used human participants. RESULTS: The search strategy yielded 34 relevant articles. These studies included procedures ranging from diagnostic catheterizations to percutaneous endovascular aneurysm repair. There is considerable heterogeneity in the studies, with a wide variety of definitions and different outcome measures. The review demonstrated that VCDs provided improvement in the patients' comfort and satisfaction as well as in the time to hemostasis and ambulation. Most studies are underpowered to show differences, but even after meta-analysis or Cochrane review, complication rates as well as safety and efficacy between devices and MC remained comparable. CONCLUSIONS: VCDs have shown marked improvement in patients' comfort and satisfaction as well as in time to hemostasis and ambulation after percutaneous vascular procedures. According to multiple small randomized controlled trials, meta-analyses, and a Cochrane review, complication rates, safety and efficacy, and outcomes remain comparable between VCDs and MC (12% for VCDs vs 13% for MC). VCDs have a low incidence of major complications and high success rates, which provides convenience for the practitioner and facilitates turnover of patients. VCDs have a risk of infectious (0.6% with VCDs vs 0.2% with MC) and thrombotic complications (0.3% with VCDs vs none with MC) that is small but may be increased compared with MC. It is important to balance the goals of comfort of the patient, resources of the staff, and early ambulation against periprocedural and anatomic risk factors (ie, individualize use of VCDs to specific clinical scenarios). Users must be familiar with a device and its limitations to safely and effectively achieve hemostasis after femoral artery puncture.

Suture-Based Vascular Closure Versus Surgical Closure of Large Bore Arteriotomies: A Real-World Experience.

INTRODUCTION: With the introduction of transcatheter aortic valve implantation (TAVI), endovascular abdominal aortic aneurysm repair (EVAR), thoracic endovascular aortic aneurysm repair (TEVAR), and frequent use of left ventricular assist devices in complicated percutaneous coronary interventions, the use of large bore arterial access has become a necessity. In the index study, we compared the percutaneous closure of large arteriotomies with open surgical (OS) closure. METHODS: It was a prospective study in which we compared the technical success and vascular complication rate associated with the use of a suture-based vascular closure device (VCD): Perclose ProGlide (PP) with that of OS closure. The study was carried out at Command Hospital Air Force, Bengaluru, India, from January 1, 2016, to December 31, 2020. The inclusion criteria were any percutaneous intervention involving large bore arterial access (≥12 French (F) sheath). The exclusion criteria were any condition where a persistent need for vascular access at the end of the procedure was required. We noted the baseline characteristics and type of anesthesia for all patients. The primary outcome was technical success and major vascular complications, which included major local site bleeding: Bleeding Academic Research Consortium (BARC) 3 or more, failed hemostasis requiring a second intervention, and acute vessel occlusion. Total time taken for the procedure (TTP), time to ambulation (TTA), and time to discharge post-procedure (TTD) were noted for each patient. The secondary outcomes were any bleeding other than major, local hematoma sized >5 cm at 24 hours, pseudo aneurysm formation at 30 days, and acute limb ischemia at 30 days. RESULTS: A total of 120 patients (PP: 60 (males: 54, females: 6), OS: 60 (males: 50, females: 10)) were included in this study. The mean age of patients was comparable in both groups (PP: 71.8 ± 9.62 years and OS: 71.0 ± 7.76 years, p-value: 0.63). Total large arteriotomies (mean size: 18.03F ± 3.34) closed were 184 (PP: 90, OS: 94). The procedures performed were EVAR: 64 (PP: 30, OS: 34), TAVI: 38 (PP: 21, OS: 17), and TEVAR: 18 (PP: 9, OS: 9). All patients in PP group received dual ProGlide with preclose technique. All TEVAR procedures (total arteriotomies: 18) required a vascular sheath of ≥ 24F. There was no statistical difference between the mean size of sheaths used in the two groups. The technical success (PP: 95.55%, OS: 97.87%, 95% CI: -5.78%-10.98%, p-value: 0.48) and rate of major complications were similar in both groups. Three patients in the PP group who had failed hemostasis with two ProGlides were successfully managed with one additional Angioseal (6F) each. The occurrence of hematoma sized larger than 5 cm was significantly more in the PP group compared to the OS group (PP: 7 (7.78%), OS: 0 (0%), p-value: 0.006). While GA was used for all patients who underwent vascular closure with OS, only eight patients (13.33%) in the PP group required GA. The TTP, TTA, and TTD were significantly lower in the PP group as compared to the OS group. CONCLUSION: The percutaneous closure of large bore arteriotomies with suture-based VCDs is equally effective and is not associated with increased major vascular complications. In fact, the TTP, TTA, and TTD are significantly lower in the PP group which can translate to better patient comfort and lower costs.

Simple, effective and safe vascular access site closure with the double-ProGlide preclose technique in 162 patients receiving transfemoral transcatheter aortic valve implantation.

OBJECTIVES: Aim of this study was to analyze feasibility, efficacy, and safety of a double-ProGlide preclose technique for access site closure after transfemoral transcatheter aortic valve implantation (TAVI). BACKGROUND: An effective and safe transcutaneous closure device is advantageous in transfemoral TAVI to avoid surgical cut down of the large caliber sheath insertion site. The use of two ProGlide sutures has not been described in this context in a large patient cohort. METHODS: ProGlide closure was used between 2010 and 2012 in 162 patients. ProGlide sutures were deployed in a preclose technique prior to insertion of the large caliber sheath. Success of the closure technique was defined as effective hemostasis and no further access site-related vascular or bleeding complications during the index hospitalization. RESULTS: Patients were 82 ± 5 years old with a logistic EuroSCORE of 16.7 ± 12.5. Edwards SAPIEN valves were used in 81.5% and Medtronic CoreValves in 18.5%. The overall success rate of the double-ProGlide technique was 93.9%. Success rate was only 40.0% under circumstances of prolonged high-dose heparinization. Success rate was 96.8% among the patients on dual-antiplatelet therapy (DAPT). All 10 ProGlide failures could effectively be managed by either percutaneous angioplasty or surgical reconstruction. The rate of VARC major vascular complications was 4.3%. Thirty-day mortality was 5.6%. CONCLUSION: The double-ProGlide preclose technique offers a simple, highly effective, and safe method for closure of the arterial access site after transfemoral TAVI. The double-ProGlide strategy results in low rates of major vascular complications and translates into favorable early outcome.

Learning Curve of Perclose ProGlide Utilization During Percutaneous Coronary Intervention.

OBJECTIVE: This study aimed to investigate the learning curve (LC) of Perclose ProGlide (Chicago, IL: Abbott Laboratories) utilization for percutaneous coronary intervention (PCI) for the first time. METHODS: The study was conducted in a prospective manner and the final sample of the study was determined as 80 patients. Patients' characteristics, diameter of common femoral artery (CFA), distance from skin to CFA, degree of calcification (<50% or ≥50%), procedure-related parameters, complications, and success of procedures were recorded. Patients were equally divided into four groups and groups were compared according to patient demographic properties, procedure-related parameters, complications, and success. RESULTS: The mean age and mean BMI of the study population were 55.5 years and 27.5 kg/m2, respectively. The mean procedure time was 144.8 minutes (min) in group 1, 138.9 min in group 2, 122.2 min in group 3, and 101.1 min in group 4, and the difference was statistically shorter in favor of group 3 and group 4 (p=0.023). Moreover, mean fluoroscopy time significantly decreased after 20 cases (p=0.030). Hospitalization period was significantly shortened following 40 procedures (p=0.031). Complications were detected in five patients in group 1, four patients in group 2, and one patient in group 4 (p=0.044). Success was significantly higher in group 3 and group 4 in comparison to group 1 and group 2 (p=0.040). CONCLUSION: This study showed that procedure time and hospitalization time significantly decreased after 40 cases and fluoroscopy time significantly decreased after 20 cases. Moreover, after 40 procedures, the success of Perclose ProGlide utilization during PCI significantly increased and complications of the procedure significantly decreased.

Transcatheter Aortic Valve Migration During Vascular Access Closure.

We present a novel complication of transcatheter aortic valve replacement (TAVR) involving prosthetic migration due to entanglement by a standard guidewire during non-large bore vascular access closure, followed by successful bail-out using a second transcatheter prosthesis. To our knowledge, this mechanism of prosthesis migration has not been previously described.

A Comparative Analysis of the Early and Late Complication Rates and the Effect of Calcification on the Efficacy of MANTA and ProGlide Vascular Closure Devices.

Introduction The Perclose ProGlide and, more recently, MANTA Large-Bore Closure Device are commonly used vascular closure devices (VCDs) for managing large-bore vascular access haemostasis. The extent of calcification in the common femoral artery (CFA) plays a crucial role in choosing between these devices. ProGlide may face challenges with anterior calcification, while MANTA may have issues with posterior calcification. Our study compared their effectiveness, adjunct usage, calcification impact and early/late complications. Methods A retrospective analysis of procedures involving large-bore CFA access from 2017 to 2022 was conducted. Closure was grouped according to VCD as Group A (ProGlide) and Group B (MANTA). Calcification was designated as anterior and posterior and combined on pre-operative computed tomography angiography along 10 mm segments with 0.625 mm slice thickness. The success of haemostasis was graded as Grade 1 (haemostasis without adjuncts), Grade 2 (haemostasis with adjuncts) and Grade 3 (failed haemostasis needing rescue); Grades 1 and 2 were pooled as successful haemostasis. Statistical analysis was undertaken in Minitab 21 for Windows, particularly analysing calcification and its impact on the success of haemostasis. Results We evaluated 370 large-bore CFA accesses, distributed across two groups: Group A(64.9%, n=243) and Group B (35.1%, n=127), for a total of 205 endovascular procedures (93.1% (191) EVAR and 5.3% (11) TEVAR). The mean age was 74.9±8 years, predominantly males (88.2%, n=181). The average body mass index (BMI) was 28±5.8, with 20.9% (43) individuals having diabetes and 18.5% (37) current smokers. The mean sheath size OD was 16±2.5, with 4.5% (11) re-do groins in Group A and 6.2% (8) in Group B. Successful haemostasis was achieved in 91.8% (n=223) in Group A (44.8%, n=109 Grade 2) and 90.5% (n=115) in Group B (21%, n=27 Grade 2). Rescue operations were needed in 8.2% (20) in Group A and 9.1% (12) in Group B. Pseudoaneurysms developed more commonly in Grade 2 haemostasis with 9.9% (11) in Group A and 1.6% (2) in Group B (p=0.3). Anterior calcification was observed in 14.8% (36) in Group A and 18.8% (24) in Group B. In comparison, posterior calcification was present in 62.5% (152) in Group A and 66.9% (85) in Group B. Notably, calcification did not significantly impact haemostasis (p=0.79). Additional VCD deployment was necessary due to device failure in 4.5% (11) cases in Group A and 1.5% (2) cases in Group B. Conclusion The overall success rate was comparable between the two groups. However, Group A required more adjuncts to achieve successful haemostasis. The site of calcification did not impact the efficacy of closure devices. Pseudoaneurysm formation was more frequent when adjuncts were needed.

Refractory Deep Vein Thrombosis Caused by Femoral Vein Stenosis Due to Suture-Medicated Vascular Closure Device.

Vascular closing devices (VCDs) are widely used to replace manual compression at the femoral puncture site after catheter insertion. Perclose ProGlide is a suture-medicated VCD that is indicated for both arterial and venous access sites. However, there are few reports of complications related to venous use of ProGlide. Here, we describe a case of femoral vein stenosis caused by a suture-medicated VCD after an ablation procedure, which developed refractory deep vein thrombosis even after surgical vascular repair.

Successful endovascular repair of complicated pseudoaneurysm using Perclose ProGlide: A novel concept.

Iatrogenic pseudoaneurysm is common vascular complications of angiographic procedures. Patients with uncomplicated pseudoaneurysms can be managed with ultrasound-guided techniques. However, for complicated pseudoaneurysms, surgical repair of the artery is mandatory. We report a case of successful repair of complicated pseudoaneurysm using an access-site closure device, Perclose ProGlide™ without a surgical approach.

Percutaneous Decannulation for Venoarterial Extracorporeal Membrane Oxygenation Using a Perclose ProGlide Closure Device and a Balloon Catheter Without On-Site Cardiac Surgical Backup.

Surgical decannulation for venoarterial extracorporeal membrane oxygenation (VA-ECMO) is recommended as a standard weaning strategy considering large-sized cannulas (14-22 French) are inserted in VA-ECMO. However, we should be aware of complications such as bleeding and infection when removing an arterial cannula, especially in facilities without on-site cardiac surgical backup. Percutaneous closure devices for femoral arterial access sites are currently approved for the decannulation of a 10-French or smaller sheath. We reported a case of successful weaning off from ECMO using a combination method of a balloon catheter and a Perclose ProGlide closure device. We successfully removed the arterial cannula using this technique for four ECMO-treated patients without vascular complications or blood transfusion. Percutaneous decannulation by this method could reduce the procedural time and adverse events and be safely performed even in facilities without on-site cardiac surgical backup.

Case report: Total percutaneous post-closure of femoral arterial access sites after veno-arterial extracorporeal membrane oxygenation.

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) which is a form of circulatory and gas exchange support. Following VA-ECMO, total percutaneous closure of the site of femoral arterial puncture with perclose Proglide (PP) has become widespread, enhancing patient comfort and lessening the incidence of wound infections and lymphatic fistulas in a short closure time. The preclose technique with perclose Proglide provides numerous benefits, however, it prolongs extra time during the VA-ECMO procedure, adds additional post-operative care to workloads, and increases the potential for Proglide stitch infection. The modified technique-percutaneous post-closure, described here by a case of a 65-year-old man with heart attack who underwent VA-ECMO, is a simple, rapidly applied technique to wean VA-ECMO also suitable for emergency cannulation. The patient was administered mechanically ventilated and sedated and the femoral artery access site and evaluated by ultrasound for precise positioning, then the VA-ECMO arterial cannula was withdrawn, and a 0.035-in guidewire was left in the artery. The first set of sutures was deployed after the Proglide device was inserted over the guidewire. The second sutures were then replaced in the same way but at a different angle. After hemostasis was achieved, the guidewire was removed, and additional manual compression was used to control any residual blood seeping. No hematoma, pseudoaneurysm, major bleeding, minor bleeding, acute arterial thrombosis, arteriovenous fistula, groin infection, lymphocele, or arterial dissection and stenosis occurred during the periprocedural period or during the 30-day post-procedural follow-up. In conclusion, the standardized algorithm we established, total percutaneous post-closure of femoral arteriotomies utilizing Perclose ProGlide device is feasible and safe with a low incidence of access site complications.

Percutaneous closure of accidentally subclavian artery catheterization: time to change first line approach?

PURPOSE: To present our experience and provide a literature review dissertation about the use of a suture-mediated percutaneous closure device (Perclose Proglide -PP- Abbott Vascular Inc., Santa Clara, CA, USA) to achieve hemostasis for unintended subclavian arterial catheterization during central venous line placement. MATERIALS & METHODS: Since October 2020, we have successfully treated four consecutive patients with a central venous catheter (8 to 12 French) in the subclavian artery. In each patient, we released a PP, monitoring its efficacy by performing a subclavian angiogram and placing, as a rescue strategy, an 8 mm balloon catheter near the entry point of the misplaced catheter. Primary outcome is technical and clinical success. Technical success is defined as absence of bleeding signs at completion angiography, while clinical success is a composite endpoint defined as absence of hematoma, hemoglobin loss at 12 and 24 h, and absence of procedure-related reintervention (due to vessel stenosis, pseudoaneurysm or distal embolization). RESULTS: Technical success was obtained in 75% of cases. In one patient a mild extravasation was resolved after 3 min of balloon catheter inflation. No early complications were observed for all patients. CONCLUSIONS: PP showed a safe and effective therapeutic option in case of unintentional arterial cannulation. It can be considered as first-line strategy, as it does not preclude the possibility to use other endovascular approaches in case of vascular closure device failure.

Iatrogenic Common Femoral Artery Occlusion Caused by a Suture-Mediated Closure System: A Case Report.

Vascular closure devices (VCDs) are useful for reducing bed rest time after percutaneous catheterization procedure without manual compression at the femoral puncture site. Occlusion of the common femoral artery (CFA) related to VCDs has rarely been reported. Although catheter treatment for CFA occlusion may be the first choice, it may be insufficient. Surgical treatment should be performed immediately when catheter treatment for artery occlusion is deemed difficult. We report a case of surgical angioplasty performed for femoral artery occlusion by using a suture-mediated device.

Perclose ProGlide embolization as a complication: case report and review of literature.

Background: Vascular closure devices have replaced mechanical compression for closure of femoral access sites after endovascular procedures. Case: We present an 87-year-old male with symptomatic infrarenal aortic aneurysm measuring 4.8 cm presenting for elective endovascular repair of the aortic aneurysm. A Perclose ProGlide Suture-Mediated Closure was used for closure. The closure was complicated by a separation of the ProGlide device resulting in the migration of the footplate to the descending aorta. Correction required snare retrieval via radial access, and the patient recovered without complications. Discussion: We highlight an important complication of the Perclose ProGlide Suture-Mediated Closure device that is rare but important to know when performing endovascular closures with this device.
