Background: The objective of this study is to report an 18-year single-center experience in the surgical and endovascular treatment of arterial complications due to self-injection in drug abuser patients. Methods: This retrospective single-center study was conducted analyzing a prospectively collected database including all endovascular or surgical procedures performed from January 2007 to December 2019 for any arterial complication due to self-injection in drug abuser patient. Collected data were patient demographic and comorbidity, site and type of arterial lesion (pseudoaneurysm [PA], arteriovenous fistula [AVF]), signs of systemic or local infection, and procedural data (endovascular/surgical treatment). End points were rate of postoperative complications, reintervention rate, limb salvage, and patients’ early and long-term survival. Results: In 11 patients (median age 36 years, range 27–47; male 73%), 13 arterial lesions were treated: 10 (77%) PA, 2 (15%) PA associated with AVF, and 1 (8%) isolated AVF. Arterial lesion involved common femoral artery in 5 (38%), superficial femoral artery in 4 (31%), profunda femoral artery in 1 (8%), brachial artery in 2 (15%), and subclavian artery in 1 (8%). Signs of infections were present in 9 of the 13 cases (69%). The treatment was surgical in 11 (85%) cases: 7 interposition graft (6 great saphenous vein, 1 arterial cryopreserved homograft), 2 direct reconstruction, 1 patch plasty with pericardium bovine patch, and 1 arterial ligation. Endovascular treatment was performed in 2 cases: 1 noninfected PA of the superficial femoral artery, and 1 55-mm PA of the postvertebral segment of the right subclavian artery with clinical sign of hemodynamic instability. At 1 month, postoperative complication rate was 8% (one lower limb claudication after superficial femoral artery ligation). Reintervention rate was 8% (interposition graft rupture for repeated self-injections). Limb salvage and patient survival were both 100%. Median follow-up was 5 years (range 1 month to 11.3 years); surgical group: median 8.2 years (range 2 months to 11.3 years); endovascular group: median 3.5 months (range 1–6). During follow-up, neither complications nor reinterventions occurred, and limb salvage was 100% for both groups. At 2, 4, and 6 years, overall estimated patient survival was 91%, 81%, and 81%, respectively, with no procedure-related death. Conclusions: After surgical or endovascular management of arterial lesions due to self-injection in drug abuser patients, complications occur mainly in the postoperative period. During follow-up, the surgical procedures have low rate of complications, reinterventions, and procedure-related mortality, whereas for the endovascular treatment the mid-term outcomes remain unknown.
