Abstract

Introduction: Acute limb ischemia is a critical medical condition that can quickly become a life threat. Therapeutic modalities such as catheter-directed thrombolysis (CDT) have demonstrated various levels of efficacy in previous studies.

Objective: This study presents the descriptive findings of a series of cases who presented with acute arterial thrombotic limb ischemia and underwent CDT.

Methods: This was a cross-sectional single-hospital-based case series, in which all patients who were diagnosed with acute arterial thrombotic limb ischemia, and consequently underwent CDT during the oneyear study period were included. Detailed baseline characteristics and clinical findings of the studied patients on presentation, after intervention and at one-year follow-up are presented.

Results: A total of 21 patients with a mean age of 60.7±15.2 years, including 16 males (76.2%) were included. The initial technical and treatment success rates were 20 (95.2%) and 14 (66.7%), respectively. The amputation-free and the overall survival rates after the one-year follow-up were 15 (71.4%) and 17 (81%), respectively. Four patients (19%) developed complications, two (9.5%) of which were significant (pulmonary hemorrhage and intraventricular hemorrhage). Amputation was performed in 6 (28.6%) cases.

Conclusion: In this study, the treatment success rate and the technical success rate were satisfactory.
