The purpose of this study is to prove the findings of a preliminary study which strongly suggest the hypothesis that the result of conventional embolectomy for acute, severe lower-limb ischemia can be improved by controlled reperfusion.

Lower Extremity Ischemia
Procedure: conventional embolectomy/thrombectomy
Procedure: embolectomy/thrombectomy with controlled reperfusion
Phase 3

Official Title: Prospektive, Randomisierte Multicenter-Studie Zur Optimierung Der Therapie Der Akuten Ischämie Der Unteren Extremitäten Durch Die Kontrollierte Extremitätenreperfusion (Prospective, Randomized Multicenter - Study for Optimization of Therapy of the Acute Ischemic Limb by Controlled Reperfusion)

Further study details as provided by University Hospital Freiburg:

Primary Outcome Measures:
  • Amputation-free survival [ Time Frame: 28 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Neurological status (motor function, sensor function) of ischemic limb [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
  • Systemic complications in both therapy groups [ Time Frame: 4 weeks ] [ Designated as safety issue: Yes ]
  • Tolerance of reperfusion solution [ Time Frame: 4 weeks ] [ Designated as safety issue: Yes ]
  • Lethality [ Time Frame: 12 months ] [ Designated as safety issue: No ]
