Vascular closure device failure: frequency and implications: a propensity-matched analysis

Minimizing femoral artery access complications during percutaneous coronary intervention: a comprehensive review

Major bleeding complications after percutaneous coronary intervention (PCI) increase patient morbidity, prolong the hospital stay and costs, and are associated with reduced survival. Transfemoral access is still preferred at many centers given its familiarity and ease of use and is necessary in cases where large bore access is needed. Multimodality imaging with fluoroscopy, ultrasonography, and angiography can facilitate proper puncture of the common femoral artery. A proper technique (which includes femoral artery puncture and vascular access site closure) associated with adequate pharmacotherapy (both during PCI and peri-procedural, for the treatment of the underlying coronary artery disease) has been shown to reduce the risk of bleeding and vascular complications associated with femoral artery access. Avoiding the use of arterial sheaths >6 French may further reduce the risk of bleeding. Data with vascular closure devices as a bleeding avoidance strategy are evolving but when used appropriately may further reduce the risk of bleeding and vascular access complications, and in this regard are synergistic with bivalirudin. Randomized trials to confirm these recommendations are needed.

Clinical and economic evaluation of ambulatory endovascular treatment of peripheral arterial occlusive lesions

BACKGROUND

Ambulatory management of patients is an alternative to conventional hospitalization. In this study we evaluate the results of a prospective cohort study of patients receiving ambulatory endovascular treatment for peripheral arterial lesions.

METHODS

From June 2008 to October 2010, ambulatory management was proposed for endovascular treatment of peripheral arterial lesions. An arterial closure device (Angio-Seal(®); St. Jude Medical) was used. For ambulatory treatment, patients were prohibited from driving a vehicle at discharge, had to be accompanied the first night after the procedure, had to live <1 hour from a medical facility, had to be reachable by telephone the day after the intervention, and had to remain hospitalized in the event of a complication. The principal criterion was morbimortality at 1 month. Secondary criteria were clinical improvement, patency, complications related to the arterial closure, and costs evaluation at 1 month.

RESULTS

Forty-five patients were included and 50 ambulatory procedures were carried out. The patients presented with claudication (92%) or a critical ischemia (8%) of the lower extremities. All procedures were carried out by femoral puncture (retrograde in 94% and anterograde in 6% of the cases). The patients presented with iliac (68%) and femoropopliteal (64%) lesions. Lesions included stenoses (70%), thromboses (16%), and intrastent restenoses (14%). The rate of failure of ambulatory hospitalization was 16% (n = 8) without a serious undesirable event: 2 patients were hospitalized after a surgical conversion for iliac rupture and disinsertion of stent; 3 patients developed a hematoma during the intervention at the point of puncture; and in 3 cases the system of percutaneous closure failed. The mean duration of hospitalization was 1.36 ± 1.33 days. At 1 month, clinical improvement was observed in 97.5% of cases, with a primary patency of 100%. No perioperative rehospitalization or puncture site complications were observed. Ambulatory management made it possible to save 42 days of hospitalization, with associated costs of 10,971€, compared with conventional hospitalization. The additional costs related to use of the Angio-Seal amounted to 7427€.

CONCLUSION

Ambulatory endovascular treatment of patients presenting with peripheral arterial lesions is reliable and effective and may contribute to savings in healthcare spending.

Complications with Angio-Seal™ vascular closure devices compared with manual compression after diagnostic cardiac catheterization and percutaneous coronary intervention

OBJECTIVES

This study assessed and compared vascular complications in CATHs and PCIs using an Angio-Seal™ vascular closure device (VCD) versus manual compression (MC).

METHODS

Secondary data analysis of a population-based multiyear cohort database was conducted to compare femoral access-related vascular outcomes in cardiac procedures using VCD and MC between May 1, 2006 and December 31, 2010. The primary outcome was any vascular complication. Propensity score adjusted analysis was conducted to reduce bias associated with covariate imbalance between the groups compared.

RESULTS

Of the 11,897 procedures, 7,063 (59.4%) used a VCD. Vascular complications occurred in 174/8,796 (2.0%) of CATHs and 82/3,004 (2.7%) of PCIs. In the CATH sample, the odds of vascular complication were 57% lower if a VCD was used (OR = 0.43, 95% CI 0.31-0.60). For the PCI sample, the risk was 49% lower if a VCD was used (OR = 0.51, 95% CI 0.31-0.81).

CONCLUSIONS

A low incidence of vascular complications was observed with the use of an Angio-Seal VCD relative to MC for both procedures.

A case of intermittent claudication associated with the Angio-Seal™ vascular closure device after carotid artery stenting

We report a case of intermittent claudication caused by the use of Angio-Seal™ vascular closure device after carotid artery stenting. This device is widely used for hemostasis at the femoral arterial puncture site. It allows early ambulation of patients and reduces labor for manual compression. However, various vascular complications have been reported. Physicians need to know the unique structure of this device and possible complications arising after deployment.

Life-threatening rupture of a false aneurysm after femoral arterial catheterization: unexpected delay after a common procedure

We report the case of a 79-year-old patient who presented with a femoral iatrogenic pseudoaneurysm of delayed and unusual onset with immediately life-threatening massive bleeding. Ultrasound is the method of choice for the diagnosis of pseudo aneurysm. If there is not spontaneous closure, ultrasound-guided compression repair, minimally invasive percutaneous treatments, and surgical repair are the three therapeutic options.

Vascular closure device failure in contemporary practice

OBJECTIVES

The goal of this study was to assess the frequency and predictors of vascular closure device (VCD) deployment failure, and its association with vascular complications of 3 commonly used VCDs.

BACKGROUND

VCDs are commonly used following percutaneous coronary intervention on the basis of studies demonstrating reduced time to ambulation, increased patient comfort, and possible reduction in vascular complications as compared with manual compression. However, limited data are available on the frequency and predictors of VCD failure, and the association of deployment failure with vascular complications.

METHODS

From a de-identified dataset provided by Massachusetts Department of Health, 23,813 consecutive interventional coronary procedures that used either a collagen plug-based (n = 18,533), a nitinol clip-based (n = 2,284), or a suture-based (n = 2,996) VCD between June 2005 and December 2007 were identified. The authors defined VCD failure as unsuccessful deployment or failure to achieve immediate access site hemostasis.

RESULTS

Among 23,813 procedures, the VCD failed in 781 (3.3%) procedures (2.1% of collagen plug-based, 6.1% of suture-based, 9.5% of nitinol clip-based VCDs). Patients with VCD failure had an excess risk of "any" (7.7% vs. 2.8%; p < 0.001), major (3.3% vs. 0.8%; p < 0.001), or minor (5.8% vs. 2.1%; p < 0.001) vascular complications compared with successful VCD deployment. In a propensity score-adjusted analysis, when compared with collagen plug-based VCD (reference odds ratio [OR] = 1.0), nitinol clip-based VCD had 2-fold increased risk (OR: 2.0, 95% confidence interval [CI]: 1.8 to 2.3, p < 0.001) and suture-based VCD had 1.25-fold increased risk (OR: 1.25, 95% CI: 1.2 to 1.3, p < 0.001) for VCD failure. VCD failure was a significant predictor of subsequent vascular complications for both collagen plug-based VCD and nitinol clip-based VCD, but not for suture-based VCD.

CONCLUSIONS

VCD failure rates vary depending upon the type of VCD used and are associated with significantly higher vascular complications as compared with deployment successes.

Practices and complications of vascular closure devices and manual compression in patients undergoing elective transfemoral coronary procedures

Femoral arterial puncture is the most common access method for coronary angiography and percutaneous coronary interventions (PCIs). Access complications, although infrequent, affect morbidity, mortality, costs, and length of hospital stay. Vascular closure devices (VCDs) are used for rapid hemostasis and early ambulation, but there is no consensus on whether VCDs are superior to manual compression (MC). A retrospective review and nested case-control study of consecutive patients undergoing elective transfemoral coronary angiography and PCI over 3 years was performed. Hemostasis strategy was performed according to the operators' discretion. Vascular complications were defined as groin bleeding (hematoma, hemoglobin decrease ≥3 g/dl, transfusion, retroperitoneal bleeding, or arterial perforation), pseudoaneurysm, arteriovenous fistula formation, obstruction, or infection. Patients with postprocedure femoral vascular access complications were compared to randomly selected patients without complication. Data were available for 9,108 procedures, of which PCI was performed in 3,172 (34.8%). MC was performed in 2,581 (28.3%) and VCDs (4 different types) were deployed in 6,527 procedures (71.7%). Significant complications occurred in 74 procedures (0.81%), with 32 (1.24%) complications with MC and 42 (0.64%) with VCD (p = 0.004). VCD deployment failed in 80 procedures (1.23%), of which 8 (10%) had vascular complications. VCD use was a predictor of fewer complications (odds ratio 0.52, 95% confidence interval 0.33 to 0.83). In the case-control analysis, older age and use of large (7Fr to 8Fr) femoral sheaths were independent predictors of complications. In conclusion, the retrospective analysis of contemporary hemostasis strategies and outcomes in elective coronary procedures identified a low rate of complications (0.81%), with superior results after VCD deployment. Careful selection of hemostasis strategy and closure device may further decrease complication rates.

Bleeding-avoidance strategies and outcomes in patients ≥80 years of age with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention (from the NCDR CathPCI Registry)

The purpose of our study was to evaluate the use of bleeding-avoidance strategies (BAS) and risk-adjusted bleeding over time in patients ≥80 years of age undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction. We analyzed data from the CathPCI Registry from July 1, 2006 through June 30, 2009. Patients were included if they were ≥80 years old, presented with ST-segment elevation myocardial infarction, and underwent primary PCI. We evaluated trends in use of BAS (direct thrombin inhibitors, vascular closure devices, and radial access) and risk-adjusted bleeding over time. Of 10,469 patients ≥80 years old undergoing primary PCI, 1,002, (9.6%) developed a bleeding complication. Use of direct thrombin inhibitors and vascular closure devices increased over time (12.8% to 24.9% and 29.2% to 32.7%, p <0.01 and <0.05 for trends, respectively). Radial access was extremely uncommon (<1%) and did not change over the course of the study. In multivariable analyses, use of BAS was associated with lower bleeding. However, over the course of the study period, overall risk-adjusted bleeding did not decrease significantly (9.9% to 9.4%, p = 0.14 for trend). In conclusion, patients ≥80 years old undergoing primary PCI are at high risk of bleeding, and despite significant increases in use of BAS, the overall rate of bleeding complications remains high.

Strategies for decreasing vascular complications in diagnostic cardiac catheterization patients

Vascular complications are the most common type of complication after a cardiac catheterization. These include hematoma, pseudoaneurysm, arteriovenous fistula, peripheral artery occlusion and dissection, and retroperitoneal bleeding. The Pennsylvania Patient Safety Authority reports that nearly half the medical errors that occurred between June 2004 and December 2006 were cardiac catheterization complications, many of which were vascular related. The American College of Cardiology's National Cardiovascular Data Registry benchmark for vascular complications incidence is less than 1% for diagnostic catheterizations and less than 3% for percutaneous coronary intervention. The need to search for strategies to decrease vascular complication in diagnostic cardiac catheterization patients was a priority.

Delayed complication from a percutaneous vascular closure device following a neuro-interventional procedure

Percutaneous vascular closure devices are being increasingly used as alternatives to manual compression for the closure of femoral arteriotomy after endovascular procedures as they appear to reduce time to ambulate, improve patient's comfort, and are implicated with cost saving. However, vascular closure devices have been associated with an increased risk of complications including hematoma formation, local bleeding, arteriovenous fistula formation, pseudoaneurysm and arterial leg ischemia. To our knowledge, if the above complications occur it is usually within the first 30 days after the procedure. None have been reported in a delayed fashion ten months or longer after closure. We describe a 30-year-old man with a history of a giant basilar trunk aneurysm. He was placed on aspirin and clopidogrel prior to the procedure. He had bilateral femoral access with 6 French sheaths. Following the procedure, 6 French Angio-Seals (St. Jude Medical, St. Paul, MN, USA) were used for closure of bilateral femoral arteriotomies. Ten months after the procedure, the patient kicked a metal cart and developed a large right retroperitoneal iliopsoas hematoma. There was no evidence of pseudoaneurysm. The patient was managed conservatively and his serial hematocrit stayed stable. He did not require surgical intervention. Use of percutaneous vascular closure devices is associated with complications including risk of hematoma, pseudoaneurysm, intravenous fistula, rectal peritoneal hemorrhage, limb ischemia and possible surgical repair. Most complications occur peri-procedure or within 30 days post-procedure. This is the first reported case of a delayed complication at ten months after the initial procedure. Site-related complications associated with percutaneous vascular closure devices may occur in a delayed fashion, even ten months post-procedure, so should be considered in the management of patients.

The fellows stitch: large caliber venous hemostasis in pediatric practice

OBJECTIVE

To analyze safety and efficiency of a subcutaneous figure of eight suture for hemostasis after large caliber venous sheath access in children.

BACKGROUND

Vascular complications remain a significant cause of morbidity after pediatric cardiac catheterization. In an attempt to reduce such complications and yet improve lab efficiency and decrease length of stay, various techniques have been applied to improve time to hemostasis.

METHODS

Prospectively recorded were vascular complications and hemostasis times in children where hemostasis was attempted using a figure of eight subcutaneous suture following large caliber venous cannulation. These were compared to a matched group achieving hemostasis using standard manual pressure techniques. Vascular ultrasound assessments were performed within 24 hr of hemostasis in both groups.

RESULTS

Thirty-two subcutaneous sutures were placed in 26 children, mean weights 31.9 kg [median (range): 29.4 (8.4 to 96) kg], with a mean sheath French size of 9.2 [8; (6 to 22)], 11 >10 French, compared to 33 sheaths in 30 cases using manual compression, mean sheath French size 9.1 (9; (6 to 13), with 10 cases ≥10 French. The mean and median times to hemostasis were shorter in the suture group: 13.6 min (P < 0.05) and 10 min (P < 0.05), respectively. Vascular complication rate was also lower in the suture group (n = 0) compared with the control group (n = 2) but did not achieve statistical significance.

CONCLUSIONS

A subcutaneous figure of eight suture hemostasis strategy can provide a safe and efficient method for large caliber venous hemostasis in a pediatric practice with improved hemostasis times and no additional morbidity.

Bleeding avoidance strategies. Consensus and controversy

Bleeding complications after coronary intervention are associated with prolonged hospitalization, increased hospital costs, patient dissatisfaction, morbidity, and 1-year mortality. Bleeding avoidance strategies is a term incorporating multiple modalities that aim to reduce bleeding and vascular complications after cardiovascular catheterization. Recent improvements in the rates of bleeding complications after invasive cardiovascular procedures suggest that the clinical community has successfully embraced specific strategies and improved patient care in this area. There remains controversy regarding the efficacy, safety, and/or practicality of 3 key bleeding avoidance strategies for cardiac catheterization and coronary intervention: procedural (radial artery approach, safezone arteriotomy), pharmacological (multiple agents), and technological (vascular closure devices) approaches to improved access. In this paper, we address areas of consensus with respect to selected modalities in order to define the role of each strategy in current practice. Furthermore, we focus on areas of controversy for selected modalities in order to define key areas warranting cautious clinical approaches and the need for future randomized clinical trials in this area.

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.
