Objective: During the COVID-19 pandemic, central venous access line teams were implemented at many hospitals throughout the world to provide access for critically ill patients. The objective of this study was to describe the structure, practice patterns, and outcomes of these vascular access teams during the COVID-19 pandemic. Methods: We conducted a cross-sectional, self-reported study of central venous access line teams in hospitals afflicted with the COVID-19 pandemic. To participate in the study, hospitals were required to meet one of the following criteria: development of a formal plan for a central venous access line team during the pandemic; implementation of a central venous access line team during the pandemic; placement of central venous access by a designated practice group during the pandemic as part of routine clinical practice; or management of an iatrogenic complication related to central venous access in a patient with COVID-19. Results: Participants from 60 hospitals in 13 countries contributed data to the study. Central venous line teams were most commonly composed of vascular surgery and general surgery attending physicians and trainees. Twenty sites had 2657 lines placed by their central venous access line team or designated practice group. During that time, there were 11 (0.4%) iatrogenic complications associated with central venous access procedures performed by the line team or group at those 20 sites. Triple lumen catheters, Cordis (Santa Clara, Calif) catheters, and nontunneled hemodialysis catheters were the most common types of central venous lines placed by the teams. Eight (14%) sites reported experience in placing central venous lines in prone, ventilated patients with COVID-19. A dedicated line cart was used by 35 (59%) of the hospitals. Less than 50% (24 [41%]) of the participating sites reported managing thrombosed central lines in COVID-19 patients. Twentythree of the sites managed 48 iatrogenic complications in patients with COVID-19 (including complications caused by providers outside of the line team or designated practice group). Conclusions: Implementation of a dedicated central venous access line team during a pandemic or other health care crisis is a way by which physicians trained in central venous access can contribute their expertise to a stressed health care system. A line team composed of physicians with vascular skill sets provides relief to resource-constrained intensive care unit, ward, and emergency medicine teams with a low rate of iatrogenic complications relative to historical reports. We recommend that a plan for central venous access line team implementation be in place for future health care crises.
We identified factors that would lead to wound complications after open femoral exposure for endovascular abdominal aortic aneurysm repair (oEVAR).Using the National Surgical Quality Improvement Program dataset (2005–2014), we examined the patients who underwent oEVAR. Patients were stratified on whether they developed postoperative wound complications. Comparisons were made between group with wound complications and those without and adjusted analyses performed to identify variables that independently increased the risk of wound complications.There were 14,868 patients in the study cohort and 2.6% (384 patients) developed wound complications after EVAR. Among those with wound complications, 94% (360 patients) of patients had superficial and deep surgical site infection. Patients who had wound complication were likely to be younger (72.6 vs. 73.7 years old (p = 0.02), functionally dependent (5.4 vs. 2.5%) (p < 0.05), smoker (3 vs. 2.4%, p =0.03), female (4 vs. 2.2%), with significantly higher body mass index (31 vs. 28), and more commonly had diabetes (4 vs. 2.4%, p < 0.001) or renal failure (12 vs. 3%, p < 0.001). Although perioperative survival was similar, patients who had wound complications had significantly longer hospital length of stay (LOS) (7.3 ± 12 vs. 3.4 ± 5 days, p < 0.001).Up to 3% patients developed wound complications after open femoral exposure during EVAR with significantly higher LOS and therefore cost utilization.
The authors report on a young patient with previous radiation to her pelvis who presented with acute limb ischemia following iliac vein stenting believed to be secondary to extrinsic iliac artery compression in the setting of a frozen pelvis. She underwent revascularization and a trans-femoral amputation, ultimately needing a femoral to femoral artery crossover bypass in order to achieve amputation stump healing. This case describes a potential arterial complication of venous stenting in a previously irradiated field.
Aortic graft infection is a feared complication after open abdominal aortic aneurysm repair secondary to its high mortality. Perigraft air is a common finding after open aortic aneurysm repair; however, it is also associated with aortic graft infection. Delineating between graft infection and common postoperative finding is a challenge. This is further complicated by use of hemostatic agents such as Gelfoam, which is also documented to cause perigraft air. Correct diagnosis has crucial implications in management of potential aortic graft infection, which is a vascular emergency. We report a case of perigraft air in a patient status after open aortic aneurysm repair with associated clinical manifestations of infection in whom conservative management and surveillance was selected for treatment. We then discuss the timeline of perigraft air, potential causation, importance of history, and physical examination, and finally, we discuss how specific findings on computed tomography imaging for infection in other areas may be useful in aortic graft infection.
The incidence of symptomatic acute cholecystitis with large (greater than 5.5 cm) abdominal aortic aneurysm is an uncommon occurrence. Guidelines on concomitant repair in this setting remain elusive, particularly in the era of endovascular repair. We present a case of acute cholecystitis in a 79-year-old female presenting to a local rural emergency room with abdominal pain and known abdominal aortic aneurysm (AAA). Abdominal computed tomography (CT) revealed a 5.5 cm infrarenal abdominal aortic aneurysm, significantly greater in size compared to previous imaging, as well as a distended gallbladder with mild wall thickening and cholelithiasis concerning for acute cholecystitis. The two conditions were found to be unrelated to each other, but concerns were raised on appropriate timing of care. Following diagnosis, the patient underwent concomitant treatment of acute cholecystitis and large abdominal aortic aneurysm with laparoscopic and endovascular techniques, respectively. In this report, we take the opportunity to discuss the treatment of patients with AAA and concomitant symptomatic acute cholecystitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
