Aspiration Thrombectomy-Assisted Endovascular Retrieval of an Embolized Angio-Seal Device Causing Claudication

The Angio-Seal vascular closure device is used to reduce time to hemostasis after femoral artery puncture. Although rare, complications associated with Angio-Seal are significant, including infection, pseudoaneurysm formation, symptomatic femoral artery stenosis, and separation and embolization, leading to limb-threatening ischemia. This report describes Angio-Seal polymer anchor embolization to the tibioperoneal trunk successfully retrieved using the 8-French Indigo Aspiration System.

Successful surgical retrieval of Celt ACD® vascular closure device embolised in the tibioperoneal trunk

Background

This report presents a case of surgical retrieval of a Celt ACD® vascular closure device (VCD) situated in the tibioperoneal trunk, following a failed attempt at deployment. Existing literature mostly recommends an endovascular approach when attempting to retrieve embolised VCDs.

Case presentation

A 55 year old male presented with right sudden right lower limb pain and numbness 1 week following a successful left retrograde superficial femoral artery (SFA) angioplasty. Computed tomography (CT) angiogram revealed that the Celt ACD® VCD had embolised in the right tibioperoneal trunk. An endovascular approach was initially attempted to retrieve the VCD; however, this was unsuccessful due to the small diameter of the target artery. Due to the failure of the endovascular approach, surgical exploration of the right tibioperoneal trunk was undertaken, which led to the successful retrieval of the embolised VCD.

Conclusion

The case presented herein demonstrates the critical need for swift and decisive surgical exploration of patients with suspected embolisation of Celt ACD® devices in smaller distal arteries. Our experience has led to the recommendation that, due to the sharp edges of the Celt ACD® accompanied with the small diameter of the occluded vessels, surgical exposure and retrieval is the safest option if endovascular retrieval is unsuccessful.

Safety and efficacy of combined micropuncture and shallow angle femoral artery access for neurovascular angiography

INTRODUCTION

The AXERA 2 low-angle vascular access device utilizes a dual arteriotomy mechanism in which the standard access tract is compressed by a vascular sheath inserted over the second, low-angle tract. It is unknown whether this device could be effectively used with 21-gauge micropuncture access, as the micropuncture introducer makes a larger arteriotomy than the 19-gauge needle provided with the AXERA 2 system.

MATERIALS AND METHODS

A retrospective review was performed on 189 patients who underwent common femoral artery access for diagnostic cerebrovascular angiography using either combined micropuncture and AXERA 2 access or standard access with manual pressure hemostasis. Demographic and procedural data were reviewed along with complications related to vascular access and times to bed elevation, ambulation and discharge.

RESULTS

Combined micropuncture and AXERA 2 access was performed on 110 patients and 79 patients had standard access. The AXERA device was successfully used in 91.8% of the cases. Demographic data, anticoagulant use and sheath sizes were similar between both subsets. Use of the AXERA 2 was associated with two bleeding complications (1.8%) compared with 10 (12.7%) with manual pressure hemostasis alone. Institution-specific protocol allowed shorter mean manual compression time, as well as shorter times to ambulation and discharge with the AXERA 2.

CONCLUSIONS

Use of the AXERA 2 device with micropuncture access did not infer increased bleeding risk than standard arterial access in this patient series. The considerable incidence of device use failures suggests a learning curve associated with its use.

A novel technique to retrieve a maldeployed vascular closure device

PURPOSE

To report a novel technique for endovascular retrieval of a maldeployed vascular closure device, obviating the need for a femoral cutdown.

TECHNIQUE

To remove a 6-F Angio-Seal device that embolized to the superficial femoral artery, the contralateral common femoral artery was accessed, and an 8-F, 65-cm-long sheath was inserted just proximal to the embolus. A second semistiff 0.035-inch buddy wire was advanced past the lesion along the sheath. A 0.014-inch wire was advanced past the embolus, and a SpiderFX embolic protection device was deployed 1 cm past the embolized Angio-Seal device. The sheath was advanced so as to push the embolus into the filter. The sheath and the filter containing the Angio-Seal device were then removed.

CONCLUSION

Endovascular retrieval of an embolized Angio-Seal device can be done using an embolic filter device, restoring arterial flow to the limb.

Feasibility of ambulatory percutaneous femoral access without the use of arterial closure systems

BACKGROUND

To evaluate the feasibility of early ambulation in patients treated for peripheral occlusive lesions by femoral percutaneous access, without the use of closure systems and the application to ambulatory practice.

METHODS

This single-center observational exploratory study was undertaken among 99 consecutive patients between August 1-December 31, 2011 (mean age: 72 years; 72 men) who were treated by percutaneous femoral route for peripheral arterial lesions. All the patients had a manual compression then pressure bandage. A clinical evaluation was carried out after 4 hours, seeking a local or a general complication and checking the procedure. Rising and walking in the unit of hospitalization were authorized in the absence of complication as of 4 hours postoperatively. All patients remained in hospital for at least 1 night, with a clinical revaluation before discharge. All patients were contacted by telephone at postoperative day 7 in order to verify the absence of local complications. All the individual factors and those related to the procedure were analyzed.

RESULTS

With criteria of complications related to the gesture, 72 patients (72.7%) were considered ready to be discharged as of postoperative hour 4. Among the 27 patients who were not able to leave, 7 presented with an early local complication without reoperation, and 20 could not walk because of a necrotic lesion (n = 8), their advanced age (n = 4), morbid obesity (n = 2), or a choice of the surgeon in charge (n = 6). Twenty-five patients could, however, stroll after 12 hours. The mean duration of hospitalization was 1.3 days (range: 0-10 days). Two patients required distal amputation during the same hospitalization, and 1 underwent a femoropopliteal bypass after failure of a femoropopliteal recanalization. With univariate analysis, the treatment by anticoagulants and the duration of the hospitalization were the only factors significantly related to the impossibility of early ambulation. The occurrence of complications was linked with the experience of the surgeon, the age of the patient, and the female sex. Three patients, including 2 regarded as ready to walk by postoperative hour 4, were rehospitalized after 1 week for reoperation because of 1 major hematoma and 2 femoral false aneurysms.

CONCLUSION

Percutaneous endovascular surgery by the femoral route without using an arterial closure system is feasible in an ambulatory practice in nearly 75% of cases. Particular monitoring must be done in the oldest patients, women, and those treated with anticoagulants.

Evaluation of the 6-F ExoSeal vascular closure device in antegrade femoral artery punctures

PURPOSE

To evaluate the safety, comfort, and efficacy of an extravascularly deployed bioabsorbable plug-based vascular closure device (VCD) for sealing 6-F antegrade access sites in patients requiring peripheral endovascular intervention.

METHODS

A single-center, single-arm, prospective study to evaluate the 6-F ExoSeal VCD in terms of technical success, adverse events, and patient comfort enrolled 59 unselected symptomatic patients (42 men; mean age 72.1 ± 9.3 years) suffering from peripheral artery disease in an 11-month period. Patients with high body mass index (BMI) or calcification at the access site were not excluded. Calcifications of the access vessel were scored as grades 1-4 from fluoroscopic images. The pain level during implantation was evaluated after the procedure using a visual rating scale.

RESULTS

Technical success rate was 98.3%; 1 primary device failure was converted to manual compression. In addition, 1 (1.7%) pseudoaneurysm, 2 (3.4%) minor hematomas, and 1 (1.7%) minor secondary bleeding were observed. There was no intravascular application of the device detected. Neither BMI, calcification of the access vessel (present in 74.6%, mean score 1.4 ± 1.1), age, nor blood clotting had any statistically significant influence on adverse events. In total, 55 (93.2%) patients felt no pain during the VCD implantation.

CONCLUSION

The tested VCD was safe, with an excellent technical success rate even in cases with severe access vessel calcification.

Safety and efficacy of the StarClose vascular closure device in more than 1000 consecutive peripheral angioplasty procedures

PURPOSE

To present a large single-center retrospective study investigating the safety and efficacy of the StarClose extravascular closure device in achieving hemostasis after antegrade or retrograde femoral artery catheterization during peripheral angioplasty procedures.

METHODS

Between January 2004 and October 2009, 1213 StarClose devices were implanted in 850 consecutive patients (598 men; mean age 65.8 ± 12.2 years) who underwent peripheral endovascular procedures. Femoral artery punctures included 625 (51.5%) retrograde and 588 (48.5%) antegrade accesses. The primary endpoints were hemostasis success, device failure, and major and minor complication rates up to 30 days.

RESULTS

A 6-F vascular sheath was used in the majority of cases [39 (3.2%) 7-F and 9 (0.7%) 8-F]. The device was applied more than once in the same femoral artery of 124 (10.2%) limbs during different angioplasty sessions. Overall hemostasis success was achieved in 1139 (93.9%) cases. In 237 (20.8%) of those, additional manual compression for <5 minutes was necessary due to immediate vessel oozing. The remaining 74 (6.1%) cases required prolonged standard manual compression because of hemostasis failure, including 13 (1.1%) failures to deliver the clip. Overall major and minor complication rates were 0.3% (4/1213) and 5.3% (64/1213), respectively.

CONCLUSION

The StarClose vascular closure device is safe and effective in achieving hemostasis during antegrade and retrograde peripheral angioplasty procedures.

CIRSE vascular closure device registry

PURPOSE

Vascular closure devices are routinely used after many vascular interventional radiology procedures. However, there have been no major multicenter studies to assess the safety and effectiveness of the routine use of closure devices in interventional radiology.

METHODS

The CIRSE registry of closure devices with an anchor and a plug started in January 2009 and ended in August 2009. A total of 1,107 patients were included in the registry.

RESULTS

Deployment success was 97.2%. Deployment failure specified to access type was 8.8% [95% confidence interval (95% CI) 5.0-14.5] for antegrade access and 1.8% (95% CI 1.1-2.9) for retrograde access (P = 0.001). There was no difference in deployment failure related to local PVD at the access site. Calcification was a reason for deployment failure in only <0.5% of patients. Postdeployment bleeding occurred in 6.4%, and most these (51.5%) could be managed with light manual compression. During follow-up, other device-related complications were reported in 1.3%: seven false aneurysms, three hematoma >5.9 cm, and two vessel occlusions.

CONCLUSION

The conclusion of this registry of closure devices with an anchor and a plug is that the use of this device in interventional radiology procedures is safe, with a low incidence of serious access site complications. There seems to be no difference in complications between antegrade and retrograde access and other parameters.
