Predictors of complications following sheath removal with percutaneous coronary intervention

An alarm device for mechanical compression device displacement at femoral artery puncture sites

OBJECTIVE

To develop an alarm device for the mechanical compression device displacement (MCD), and further evaluate its effectiveness in clinical use.

MATERIAL AND METHODS

The alarm device is mainly composed of buzzer, indicator light, magnetic sheet. This is a prospective randomized and controlled study. Four hundred patients who met the inclusion/exclusion criteria were included and randomly assigned to two groups (MCD group vs alarm + MCD group). The primary outcome measures were the sensitivity and specificity of the alarm device to detect MCD displacement, time to hemostasis (TTH), time to ambulation (TTA), time to hospital discharge (TTHD), hospital costs (HC), complication rates, and patient satisfaction.

RESULTS

The sensitivity and specificity of the alarm device in detecting MCD displacement were 94.44% and 88.46%, respectively. The study group achieved shorter TTH (p = .034), shorter TTA (p = .021), lower complication rates (p = .025), and better patients' satisfaction (p < .001) compared to the control group. However, no significant difference was observed in TTHD (p = .361) and HC (p = .583).

CONCLUSION

The alarm device is highly sensitive in detecting MCD displacement, while achieving better clinical outcomes compared with artificial monitoring.

Percutaneous Ultrasound-Guided Carotid Access and Puncture Closure with Angio-Seal in Horses

Simple Summary

Endovascular surgery is a type of image-guided minimally invasive surgery that aims to solve different types of pathologies from inside the blood vessel. This technique requires access to a peripheral vessel (vein or artery) and the navigation through the vascular system to reach the operating site, using different catheters. In horses, the main indication for endovascular therapy involves access to the common carotid artery for different purposes. Traditionally, this was performed by open dissection of the neck to reach and incise the common carotid artery, followed by vascular suture of the vessel and skin closure when the procedure was over. However, this can also be performed by percutaneous puncture of the artery, using ultrasound to guide the needle to its adequate position in the artery, as has been reported in experimental horses. Along with that, in human medicine, commercial closure systems are used to seal these arterial punctures and avoid some complications (mainly haematomas and haemorrhages). We describe our experience in a series of 11 clinical cases in which this minimally invasive way of access was used, and the puncture site was sealed with one of these devices (AngioSeal arterial closure system), reporting its first use in horses. In all cases, the artery was effectively accessed, and the planned procedure could be performed. Our haematoma/bleeding rate (16.66%) was lower than in other studies using the same type of access, even considering two failures due to incorrect use of the device. However, further studies comparing AngioSeal use to simple manual compression would be necessary to be able to recommend their routine use in horses.

Abstract

Background: There are different indications for endovascular surgery in horses, mainly the treatment of guttural pouch mycosis. Traditionally, these procedures are carried out by open arteriotomy of the common carotid artery (CCA), although less invasive percutaneous ultrasound-guided carotid access (PUGCA) has been described in experimental horses. In human medicine, commercial closure systems are used to seal these arterial puncture sites and reduce complications. The aims of this study are to retrospectively describe our experience with PUGCA in clinical cases and to report, for the first time, the use of the commercial vascular closure device Angio-Seal after PUGCA in horses. Methods: Retrospective study of clinical case records. Collected parameters, including the feasibility of the PUGCA and variables related to the safety and efficacy of the use of the Angio-Seal. Results: Twelve PUGCA procedures in 11 horses were included. In all cases, the artery was effectively accessed, and the planned procedure could be performed. In two cases, haematoma/bleeding due to incorrect use of the Angio-Seal was recorded. This complication rate (16.66%) was lower than that obtained in other studies using PUGCA in horses, but where the puncture was sealed by manual compression only. Main limitations: A control group of clinical cases with PUGCA but without using Angio-Seal is not available. Conclusions: Clinical data confirm previous experimental results, which showed that PUGCA is safe and effective in horses. The Angio-Seal system, regardless of possible complications due to incorrect use, can be used safely and effectively in horses. Further studies comparing arterial access site management using manual compression or Angio-Seal would be necessary to state if its routine use in horses is advisable.

Comparison of the effectiveness of position change for patients with pain and vascular complications after transfemoral coronary angiography: a randomized clinical trial

BACKGROUND

Prolonged immobilization after transfemoral coronary angiography (TFA) may cause pain and vascular complications in patients. This study aimed to evaluate the effectiveness of a change in position to decrease pain and vascular complications for patients after TFA.

METHODS

This randomized clinical trial was conducted in 2020. Purposive sampling of 72 eligible patients undergoing TFA were selected and randomly assigned to either an experimental or control group. Patients in the experimental group (EG) were placed in a supine position for 2 h after angiography, followed by a semi-seated position with the bed angle gradually increased to 45° over 4 h. Patients in the control group (CG) remained in the supine position for 6 h. Vital signs, groin, back and leg pain, hematoma, hemorrhage, and urinary retention were assessed in both groups before, immediately after, and over 6 h after angiography. The Visual Analogue Scale was used to measure pain, the Christensen scale to measure hematoma, counting bloody gases to measure hemorrhage, and patient self-rating to determine urinary retention.

RESULTS

There was no significant difference between EG and CG on score of groin (2.69 ± 1.00 vs. 2.61 ± 1.00, P = 0.74), back (2.19 ± 0.98 vs. 2.47 ± 0.87, P = 0.21), and leg pain (2.14 ± 0.71 vs. 2.50 ± 1.08, P = 0.27) before the TFA. However, from the second hour to the sixth hour after the TFA, the pain in the EG was significantly less than the CG (P < 0.001). So that pain in the groin (1.36 ± 0.48 vs. 3.28 ± 0.81), back (1.25 ± 0.50 vs. 3.81 ± 1.06), and leg (1.44 ± 0.55 vs. 3.28 ± 0.81) for the EG patients was significantly less than the CG in the sixth hour after TFA (P < 0.001). No patients experienced hematoma. No differences were noted between groups in hemorrhage and urinary retention.

CONCLUSIONS

Position change to a semi-seated position in patients after TFA is effective and safe for reduction of pain without increasing vascular complications.

The effect of the application of cold on hematoma, ecchymosis, and pain at the catheter site in patients undergoing percutaneous coronary intervention

Objective

This study was conducted to determine the effect of the application of cold on hematoma, ecchymosis, and pain in patients undergoing percutaneous coronary intervention.

Methods

It is a quasi-experimental study with a control group. A total of 200 patients (100 in the control group and 100 in the experimental group) were included in the research. In the experimental group, a cold pack was applied to the bottom of the sandbag for the first 15 min after withdrawing the femoral arterial catheter. Both groups were assessed and followed up at the first 15th minute and 4th, 48th and 72 nd h.

Results

After the femoral arterial catheter was withdrawn, ecchymosis and hematoma were smaller and pain was less in the experimental group at the catheter entry site compared to the control group, and the difference was statistically significant (P < 0.01).

Conclusion

It was determined that the application of cold reduced the formation of hematomas, ecchymoses and pain in patients after the withdrawal of the femoral arterial catheter.

Malignancy Associated Iatrogenic Iliopsoas Abscess -Venous Access Complication From Ablation Procedure

Iliopsoas abscess is a rare condition with a high rate of mortality and morbidity if left untreated. It can occur from hematogenous or lymphatic spread from distant structures or as a result of contiguous spread from adjacent structures. The disease typically occurs in patients with immunocompromised status and the symptoms can be non-specific.1,2 Generally, infectious complications from venous access during atrial fibrillation (AF) procedure are uncommon, and an iatrogenic iliopsoas abscess from percutaneous cardiac procedures has never been reported. We present the first case of iliopsoas abscess from an ablation procedure.

Reliability of vascular access site bruise measurement

BACKGROUND AND PURPOSE

Vascular access site (VAS) bruising is common following invasive cardiac procedures. The extent of VAS bruising is underreported because of the lack of reliable measurement methods. This study examined the reliability of linear measurement and planimetry to measure VAS bruise size.

METHODS

There were 40 participants with VAS bruising after invasive cardiac procedures who completed VAS bruise measurement. Participants, a principal investigator, and a research assistant completed measurements independently. Inter-rater reliability was determined using intraclass correlation coefficient (ICC), 2-way random effects model.

RESULTS

The ICC for linear measurement and planimetry was high (.929 and .914 respectively). Both methods were reliable measures of VAS bruise size.

CONCLUSIONS

Linear measurement or planimetry can be used with confidence to measure VAS bruising in clinical and research contexts.

Access site complications after peripheral vascular interventions: incidence, predictors, and outcomes

BACKGROUND

Access site hematomas and pseudoaneurysms are the most frequent complications of peripheral vascular intervention (PVI); however, their incidence and risk factors remain unclear.

METHODS AND RESULTS

We retrospectively analyzed data from the multicenter Vascular Quality Initiative on 22 226 patients who underwent 27 048 PVI from August 2007 to May 2013. Primary end points included incidence and predictors of access site complications (ASCs), length of postprocedural hospitalization, discharge status, and 30-day and 1-year mortality. ASC complicated 936 procedures (3.5%). Of these, 74.4% were minor complications, 9.7% were moderate requiring transfusion, 5.4% were moderate requiring thrombin injection, and 10.5% were severe requiring surgery. Predictors of ASC were age >75 years, female sex, white race, no prior PVI, nonfemoral arterial access site, >6-Fr sheath size, thrombolytics, arterial dissection, fluoroscopy time >30 minutes, nonuse of vascular closure device, bedridden preoperative ambulatory status, and urgent indication. Mean hospitalization was longer after procedures complicated by ASC (1.2±1.6 versus 1.9±1.9 days; range, 0-7 days; P=0.002). Severity of ASC correlated with higher rates of discharge to rehabilitation/nursing facilities compared with home discharge. Patients with severe ASC had higher 30-day mortality (6.1% versus 1.4%; P<0.001), and those with moderate ASC requiring transfusion had elevated 1-year mortality (12.1% versus 5.7%; P<0.001).

CONCLUSIONS

Several factors independently predict ASC after PVI. Appropriate use of antithrombotic therapies and vascular closure device in patients at increased risk of ASC may improve post-PVI outcomes.

Bed rest duration after sheath removal following percutaneous coronary interventions: a systematic review and meta-analysis

AIMS AND OBJECTIVES

To explore the effect of bed rest duration after sheath removal following percutaneous coronary interventions on the incidence of vascular complications, back pain and urinary problems.

BACKGROUND

According to the literature, the duration of bed rest after sheath removal following percutaneous coronary interventions ranges from 2-24 hours. Several studies have assessed the effect of duration of bed rest on vascular complications, but a clear final conclusion about the exact duration of bed rest has not been reached.

DESIGN

Systematic review and meta-analysis.

METHODS

Cochrane Library, MEDLINE, SCOPUS, CINAHL, IranMedex and IranDoc were searched. No language limitation was applied. RCTs that used two different periods for ambulation were included. Two reviewers separately assessed the quality of each included study and extracted the data. Dichotomous outcomes were recorded as odds ratio with 95% confidence interval.

RESULTS

Five studies involving 1115 participants were included in the review. Among them, two studies had three comparison groups. The studies considered a variety of periods as early and late ambulation, ranging from 2-10 hours. Totally, there were no statistically significant differences in the incidence of bleeding, pseudoaneurysm, arteriovenous fistula and urinary problems between early and late ambulation. There was a statistically significant reduction in the risk of haematoma formation at four to six hours of bed rest compared with eight hours of bed rest (odds ratio = 0·37, 95% CI: 0·15, 0·91). Back pain was reported in one study evaluating three hours of bed rest with an odds ratio of 0·45 (95% confidence interval: 0·28, 0·71) when compared with 10 hours of bed rest.

CONCLUSIONS

Early ambulation after percutaneous coronary interventions is safe and feasible; however, the results should be used with caution as the majority of included studies had methodological flaws.

RELEVANCE TO CLINICAL PRACTICE

The results of this study suggest that patients could be ambulated three to four hours after sheath removal following percutaneous coronary interventions and early ambulation dose does not increase the risk of vascular complications, but it moderates back pain occurrence.

Managing Risk of Complications at Femoral Vascular Access Sites in Percutaneous Coronary Intervention

Percutaneous coronary intervention for acute coronary syndrome or non–ST-elevation myocardial infarction requires the use of potent oral and intravenous anti-platelet and antithrombin medications. Although these potent antithrombotic agents and regimens may increase the effectiveness of percutaneous coronary intervention, they are also generally associated with an increased risk of vascular access complications such as hematoma, retroperitoneal hematoma, pseudoaneurysm, arterial occlusion, and arteriovenous fistula, which in turn are associated with increased morbidity, mortality, and costs. Risk factors predisposing patients to these complications are both modifiable (procedure technique, medications, hemostasis method) and nonmodifiable (sex, age, body mass index, blood pressure, renal function). Patients’ risks can be reduced by nurses who are knowledgeable about these risk factors and identify complications before they become problematic.

Use of expanded polytetrafluoroethylen (ePTFE) stent graft in autogenic AV fistula with false aneurysm in lower extremity

A 28-year-old German-Caucasian man arrived with deep vein thrombosis DVT, pain, oedema and rubor of right lower limb and drug abuse. The US Doppler imaging showed an autogenic AV fistula and false aneurysm of the right superficial femoral artery and femoral vein. The CT imaging showed additional closing of the left external iliac artery and common femoral artery, and of the distal and middle parts of the superficial femoral artery. The patient was treated within the angiography suite using a 8/25 mm (8 mm diameter/25 mm length) peripheral graft with expanded polytetrafluoroethylen ePTFE stent. After stent deployment, the dilatation was performed using 8/20 mm (8 mm diameter/20 mm length) balloons. After intervention, the digital subtraction angiography showed a good stent position with complete exclusion of false aneurysm and AV fistula. The outcome of US Doppler imaging also confirmed successful intervention.
