Incidence and correlates in the development of iatrogenic femoral pseudoaneurysm after percutaneous coronary interventions

Incidence and predictors of groin complications early after coronary artery intervention: a prospective observational study

Background

Coronary artery disease remains the most common single cause of death worldwide. Percutaneous coronary intervention is an appropriate management for coronary artery disease which is not free from its potential complications. The purpose of this study was to determine the incidence rate and the predictors of groin complications post percutaneous coronary intervention in cardiac catheterization laboratories in Jordan.

Methods

This was a prospective observational study with a consecutive sample of 300 patients post percutaneous coronary intervention procedure. Data were collected from the cardiac health care center using a pre-structured observational sheet. Any groin complication developed within the first 24 h post procedure was recorded. All correlated variables were analyzed using logistic regression.

Results

The sample included 237 (79%) men and 63 (21%) women with a mean age of 57.46 ± 10.51 years. A total of 114 patients (38%) developed one or more groin complications. Ecchymosis was the most frequent groin complication; 102 (34%). Females and participants greater than 65 years were nearly two times more likely to develop groin complications (OR = 2.13, P = .024, 95% CI: 1.11-4.01) and (OR = 2.14, P = .023, 95% CI: 1.11-4.13) compared to other groups. Patients with a systolic blood pressure before sheath removal greater than 180 mmHg were about ten times more likely to develop groin complications (OR = 9.82, P = .001, 95% CI: 2.58-37.37).

Conclusions

Different factors can increase the risk of groin complications post percutaneous coronary intervention. Therefore, identification of high risk groups (i.e. females) might help in the application of different methods to control these complications.

Pseudoaneurysm

Pseudoaneurysms (PSAs) are commonly known as complications associated with invasive interventions. Because of the pulsatile in- and outflow of blood through the neck of PSAs, they tend to grow and, in the worse cases, can rupture. Therapeutic options are compression therapy, using a compression bandage and ultrasound-guided compression, and thrombin injection. Manual ultrasound-guided compression is widely performed and is successful in most cases. In general, it is combined with a subsequently applied compression bandage. Thrombin injection is a more difficult technique, but it has a higher success rate. This article gives an overview of the characteristics of PSAs, their diagnostic characteristics and the therapeutic methods used to treat them. Complications associated with compression or thrombin injection are also explained in detail.

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.
