Emergency autologous vein graft reconstruction after vascular closure device usage and subsequent infection

Different techniques and devices can achieve haemostasis after endovascular procedures to reduce time to haemostasis and facilitate percutaneous large-bore access. One such device is the Angio-Seal, which accomplishes haemostasis by compressing a collagen plug against the arteriotomy. Multiple complications related to Angio-Seal exist, most commonly acute artery occlusions and rarely infections and endarteritis. We present a case of an adult male (aged 80-85) who developed a groin haematoma associated with Angio-Seal use. Arterial bypass for arterial reconstruction and intravenous antibiotics were required. This case addresses the associated pathologies of Angio-Seal failure and Angio-Seal infection, patient- and device-specific risk factors and measures to treat and prevent these complications (ANGIO-SEAL VIP Vascular Closure Device-6 Fr Terumo Medical, NJ, USA).

Real-World Experience With the Angio-Seal Closure Device: Insights From Manufacturer and User Facility Device Experience Database

PURPOSE

Angio-Seal (Terumo Medical Corporations, Somerset, New Jersey) device is indicated for femoral arteriotomy closure. Real-world published data on complications are limited. We present 1 year of safety events involving Angio-Seal from the US Food and Drug Administration's post-market surveillance database of Manufacturer and User Facility Device Experience (MAUDE). Steps for managing frequent device-related problems are discussed.

MATERIALS AND METHODS

Angio-Seal MAUDE data from November 2019 to December 2020 was classified according to (1) mode of device failure, (2) complication, (3) treatment, and (4) Cardiovascular and Interventional Radiological Society of Europe (CIRSE) adverse event classification system.

RESULTS

There were 715 safety events, involving Angio-Seal VIP (93.1%), Evolution (5.7%), STS Plus (1.1%), and sizes 6F (62.5%) and 8F (37.5%). Failure mode involved unrecognized use of a damaged device (43.4%), failed deployment (20.1%), failed arterial advancement (6.3%), detachment of device component (4.9%), failed retraction (3.6%), operator error (1.1%), and indeterminate (20.6%). Of total, 44.8% of events were associated with patient harm. Complications involved minor blood loss (34.1%), hematoma (5.6%), significant blood loss (1.4%), and pseudoaneurysm (1.4%). Of total, 43.3% of cases required manual compression (MC), whereas 8.8% required more advanced intervention. Interventions included surgical repair (49.2%), thrombin injection (9.5%), balloon tamponade (6.3%), covered stent (4.8%), and unspecified (30.2%). Majority of safety events were CIRSE grade 1 (92.0%), followed by grades 2 (3.1%), 3 (4.6%), and 6 (deaths, 0.3%). Minority of devices were returned for manufacturer analysis (27.8%).

CONCLUSIONS

The majority of safety events were associated with minor blood loss or local hematoma and could be addressed with MC alone. Most events were attributed to damaged device; however, very few devices were returned to manufacturer for analysis. This should be encouraged to allow for root cause analysis in order to improve safety profile of devices. System-level strategies for addressing barriers to under-reporting of safety events may also be considered.

CLINICAL IMPACT

Our study highlights important safety events encountered in real-world practice with Angio-Seal closure device. The MAUDE database captures real-world device malfunctions not typically appreciated in conventional clinical trials. Our study provides valuable insight for clinician-users on anticipating and managing the most common device malfunctions. Additionally, our data provide feedback for manufactures to optimize product design and direct manufacturer user training to improve safety. Finally, we hope that the study promotes system-level strategies that foster reporting of safety events and undertaking of root cause analysis.

Complications with the use of Angio-Seal vascular closure device and their management

Vascular closure devices (VCDs) are being increasingly used for achieving hemostasis after diagnostic and therapeutic endovascular procedures. Although uncommon, complications may be encountered which are associated with the use of these VCDs. We report four cases where the use of Angio-Seal (Terumo, Somerset, New Jersey, USA) was followed by complications. Three cases presented with acute limb ischemia, among them, two patients had arterial occlusion at the vascular access site and one patient had embolization of the footplate anchor of the closure device. One case presented with pseudoaneurysm at the common femoral artery access site along with occlusion at origin of the superficial femoral artery. We have described the mechanism in which these complications occur and the successful management of these cases preventing potential amputation and limb loss. The risk factors which increase the risk of complications with the use of Angio-Seal VCD were reviewed and the strategy to avoid these complications with particular emphasis on the utility of ultrasound when using Angio-Seal VCD is discussed. A strategy to manage these complications has been discussed while deciding on endovascular management or surgical management, especially in patients with challenging presentation and those with multiple comorbidities making them at very high risk for surgery.

[Vascular access-site infections in percutaneous cardiac interventions: A significant risk?]

Vascular access site infections are infrequent and rarely reported as a potential complication of percutaneous cardiac intervention. A case of access site infection is reported with a literature review. Femoral access is mainly concerned in some circumstances: delayed sheath withdrawal, vascular complications (hematoma, false-aneurysm, arteriovenous fistula), or use of hemostatic closure device. These infectious complications are always serious requiring medical and surgical treatment and potentially associated with life-threatening complications. Preventive measures should be applied in order to reduce the risks: optimisation of femoral punctures with the support of echography guidance, avoid a new puncture in a area with hematoma, femoral angiographic evaluation and strict aseptic precautions with vascular closure devices, and obviously preferential choice of radial access.

Methicillin-sensitive S taphylococcus aureus bacterial endarteritis associated with vascular closure device

Percutaneous endovascular procedures (PEPs) are increasingly common in clinical practice. Percutaneous closure devices (PCD) ensure safe and immediate haemostasis, reducing the length of hospitalisation and improving patient comfort. Infectious complications are rare. We present the case of a 65-year-old man who was admitted to hospital because of fever and weight loss. He had a history of carotid arterial disease, having been submitted to a PEP 3 weeks before. On admission, he presented feverishly. Anaemia and elevated inflammatory parameters were detected on basic chemistry. Blood cultures isolated methicillin-sensitive Staphylococcus aureus and antibiotic therapy was started. He maintained fever and developed signs of right lower limb ischemia. Bacterial endocarditis was ruled out. Positron emission tomography (PET)-scan revealed inflammatory activity involving the right femoral artery (RFA). Bacterial femoral endarteritis was confirmed on surgical exploration, which documented the presence of infected PCD and occlusion of RFA. After surgery, apyrexia and improvement of ischaemic signs were achieved.

Pharmacology of Peripheral Arterial Disease in the Angio Suite: What Every Interventionalist Should Know

Safe and effective treatment of peripheral arterial disease (PAD) and critical limb ischemia can be routinely performed in the angiography suite. A systematic understanding of the medications commonly used during these procedures is essential. This review discusses the traditional roles of the medications used in PAD procedures, the existing evidence basis for those roles, potential alternatives, and evolving techniques. Developing a familiarity with these medications can help improve outcomes and safety for the patients being treated.

Multidetector CT of iatrogenic and self-inflicted vascular lesions and infections at the groin

Abstract

The number and complexity of endovascular procedures performed via either arterial or venous access are steadily increasing. Albeit associated with higher morbidity compared to the radial approach, the traditional common femoral artery remains the preferred access site in a variety of cardiac, aortic, oncologic and peripheral vascular procedures. Both transarterial and venous cannulation (for electrophysiology, intravenous laser ablation and central catheterisation) at the groin may result in potentially severe vascular access site complications (VASC). Furthermore, vascular and soft-tissue groin infections may develop after untreated VASC or secondarily to non-sterile injections for recreational drug use. VASC and groin infections require rapid diagnosis and appropriate treatment to avoid further, potentially devastating harm. Whereas in the past colour Doppler ultrasound was generally used, in recent years cardiologists, vascular surgeons and interventional radiologists increasingly rely on pelvic and femoral CT angiography. Despite drawbacks of ionising radiation and the need for intravenous contrast, multidetector CT rapidly and consistently provides a panoramic, comprehensive visualisation, which is crucial for correct choice between conservative, endovascular and surgical management. This paper aims to provide radiologists with an increased familiarity with iatrogenic and self-inflicted VASC and infections at the groin by presenting examples of haematomas, active bleeding, pseudoaneurysms, arterial occlusion, arterio-venous fistula, endovenous heat-induced thrombosis, septic thrombophlebitis, soft-tissue infections at the groin, and late sequelae of venous injuries.

Teaching Points

• Complications may develop after femoral arterial or venous access for interventional procedures.

• Arterial injuries include bleeding, pseudoaneurysm, occlusion, arteriovenous fistula, dissection.

• Endovenous heat-induced thrombosis is a specific form of iatrogenic venous complication.

• Iatrogenic infections include groin cellulitis, abscesses and septic thrombophlebitis.

• CT angiography reliably triages vascular access site complications and groin infections.

A minimally invasive technique for closing an iatrogenic subclavian artery cannulation using the Angio-Seal closure device: two case reports

Introduction

In the two cases described here, the subclavian artery was inadvertently cannulated during unsuccessful access to the internal jugular vein. The puncture was successfully closed using a closure device based on a collagen plug (Angio-Seal, St Jude Medical, St Paul, MN, USA). This technique is relatively simple and inexpensive. It can provide clinicians, such as intensive care physicians and anesthesiologists, with a safe and straightforward alternative to major surgery and can be a life-saving procedure.

Case presentation

In the first case, an anesthetist attempted ultrasound-guided access to the right internal jugular vein during the preoperative preparation of a 66-year-old Caucasian man. A 7-French (Fr) triple-lumen catheter was inadvertently placed into his arterial system. In the second case, an emergency physician inadvertently placed a 7-Fr catheter into the subclavian artery of a 77-year-old Caucasian woman whilst attempting access to her right internal jugular vein. Both arterial punctures were successfully closed by means of a percutaneous closure device (Angio-Seal). No complications were observed.

Conclusions

Inadvertent subclavian arterial puncture can be successfully managed with no adverse clinical sequelae by using a percutaneous vascular closure device. This minimally invasive technique may be an option for patients with non-compressible arterial punctures. This report demonstrates two practical points that may help clinicians in decision-making during daily practice. First, it provides a practical solution to a well-known vascular complication. Second, it emphasizes a role for proper vascular ultrasound training for the non-radiologist.
