Introduction: Retrograde access performed guided by fluoroscopy or ultrasound. We aimed to analyze the usefulness of ultrasound in retrograde access in patients with critical limb ischemia.
Methods: Observational analytical study. From December 2013 to June 2019. We included all retrograde accesses that were guided by ultrasound. Our register assesses demographic and clinical data, the vessel used as retrograde access, the procedure performed, the amount of contrast agent used and time of fluoroscopy, access failure, and local complications.
Results: On 715 procedures performed, was used ultrasound-guided retrograde access in 25 patients (64% men). The mean age was 74.8 years (45-90), with 92% of diabetics and 32% of chronic renal failure. Two patients with Rutherford stage 4 and 23 with stage 5-6. In 24 (96%) patients the ultrasound-guided puncture was successful, while in one (4%) of them, it was not possible to enter the target vessel. After the punch, was achieved the technical success of revascularization in 19 (79.2%) patients, with 5(20.8%) in whom did not the arterial injury was not overcome. The arteries used as retrograde access were: anterior tibial 11, posterior tibial 10, and peroneal in 4. The mean of contrast used was 63 mL (9-100 ml) with an average time of 43 minutes (15- 76 min). Complications related did not observe in retrograde access.
Conclusions: Ultrasound- guided retrograde distal access is an effective method that may use as a bailout method in those endovascular procedures in which it is not possible to cross the lesion anterogradely.
