Surgical Treatment of Ruptured Infectious Femoral Pseudoaneurysms Caused By Intravenous Drug Abuse: A Nonemergent (Postponed) Operation Pattern May Be a Possible Alternative

Abstract Objective: To evaluate the possibility of surgical treatment of ruptured infectious femoral pseudoaneurysms caused by intravenous drug abuse in a nonemergent operation pattern, with retrospective analysis of clinical data and experience at a single center.Methods: Clinical data of 85 consecutive patients presenting with groin area active or recent hemorrhage due to a ruptured infectious femoral artery pseudoaneurysm related to drug abuse who were treated in the First Hospital of Changsha, China, from July 2008 to June 2020 were collected and analyzed.Results: A total of 74.1% of patients presented with active hemorrhage, and 36.5% presented with significant hypotension at admission. The average interval between arrival and operation was 34.7±4.7 hours. Vital physiological parameters and overall situation improved significantly after sufficient preoperative preparation. Satisfactory hemostasis can be achieved by bandage compression or local skin suture. No case was transferred to urgent operation due to severe bleeding, and 1 postoperative death case was observed in the cohort. The main operative- and postoperative-related indicators were satisfactory and close to those in the emergent operation pattern.Conclusion: While emergent or urgent operation is the mainstream surgical treatment for ruptured infectious femoral pseudoaneurysms, nonemergent (postponed) operation with sufficient preoperative preparation might also be an acceptable and comparable choice in some cases.

Abstract Background Despite current progress in antibiotic therapy and medical management, infective endocarditis remains a serious condition presenting with high mortality rates. It also is a life-threatening complication in patients with a history of chronic intravenous drug abuse. In this study, we analyzed our institutional experience on the surgical therapy of infective endocarditis in patients with active intravenous drug abuse. The aim of the study is to identify the predictive factors of mortality and morbidity in this subgroup of patients. Methods Between 2007 and 2020, a total of 24 patients (7 female, mean age 38.5 ± 8.7) presenting with active intravenous drug abuse underwent a surgical treatment for the infective endocarditis at out center. The primary endpoint was survival at 30th day after the surgery. The secondary composite endpoint included freedom from death, recurrent endocarditis, re-do surgery, and postoperative stroke during the follow-up period. Mean follow-up was 4.2 ± 4.3 years. Results Staphylococcus species was the most common pathogen detected in the preoperative blood cultures. Infection caused by Enterococcus species as well as liver function impairment were identified as mortality predictor factors. Logistic EuroSCORE and EusoSCORE-II were also predictive factors for mortality in univariate analysis. Survival at 1 and 3 years was 78 and 72% respectively. Thirty-day survival was 88%. 30-day freedom from combined endpoint was 83% and after 1 and 3 years, 69 and 58% of the patients respectively were free from combined endpoint. Five patients (20.8%) were readmitted with recurrent infective endocarditis. Conclusion In patients presenting with active intravenous drug abuse, treatment of infective endocarditis should be performed as aggressively as possible and should be followed by antibiotic therapy to avoid high mortality rates and recurrent endocarditis. Early intervention is advisable in patients with an infective endocarditis and enterococcus species in the preoperative blood cultures, liver function deterioration as well as cardiac function impairment. Attention should be also payed to addiction treatment, due to the elevated relapse rate in patients who actively inject drugs. However, larger prospective studies are necessary to support our results. As septic shock is the most frequent cause of death, new treatment options, e.g. blood purification should be evaluated.
