Objectives:
Technical success and early outcome of modified surgical techniques integrating interventional procedures for iliac recanalisation performed through an incision in the groin.
Materials:
Sixty-one consecutive iliac arteries in 59 patients with long occlusions in 16, occlusions of the common iliac in 11, occlusions of the external iliac in 24 and multiple stenoses of the iliac in 10 cases underwent semiclosed recanalisation through a groin incision.
Methods:
Passage of the lesion by guidewire permits retrograde ring-stripper endarterectomy over the wire as a guiding splint or thrombectomy with a double lumen balloon catheter. Residual lesions are corrected by balloon or stent angioplasty. Adequate outflow is established by femoral patch plasty.
Results:
Conversion to a standard operation was required in 10 limbs (failure to recanalise the lesion in nine, rupture after angioplasty in one). Initial technical success was achieved in the remaining 51 limbs (recanalisation by ring stripper endarterectomy in 36, thrombectomy in 14, both in six, additional intraoperative angioplasty in 42). Five postoperative thromboses were successfully treated by a combined surgical and interventional approach accounting for a 1-month 100% secondary patency.
Conclusion:
Iliac recanalisation through the groin by modified ring stripper endarterectomy or modified thrombectomy in combination with intraoperative angioplasty is a safe and effective procedure. Long-term results are required to evaluate the procedure.
