The contemporary hybrid operative procedure for incapacitating post-thrombotic iliofemoral and vena caval obstruction improves procedural outcomes

Abstract

ObjectiveChronic, post-thrombotic iliofemoral and inferior vena caval obstruction is associated with debilitating morbidity. Venoplasty and stenting are often successful; however, in the presence of a diseased or occluded common femoral vein (CFV), failure is common. A hybrid operative procedure of open surgical CFV endovenectomy and endoluminal recanalization or bypass of the obstructed iliofemoral and vena caval segments has been developed and modified. The purpose of this report was to assess the technical evolution of this procedure on operative complications. MethodsThirty-one patients undergoing CFV endovenectomy and proximal ipsilateral endoluminal reconstruction (iliac, inferior vena caval) or contralateral outflow were analyzed. The initial techniques of patient management were compared with the present contemporary techniques, evaluating procedural complications and failures. The contemporary procedure evolved to include routine axial imaging, preoperative venography through the popliteal vein, preoperative passage of a guidewire or catheter into the patent vena cava, placement of an ipsilateral popliteal vein sheath for intraoperative and postoperative anticoagulation, routine patch closure, routine arteriovenous fistulas, routine completion intravascular ultrasound, and long-term anticoagulation with warfarin to a target international normalized ratio of 3.0 to 4.0. Procedure-related complications were compared between the initial and contemporary techniques. ResultsOf 17 patients treated with the early techniques, 15 (88%) had major complications: 5 iliofemoral thromboses, 4 major wound bleeds, 4 wound infections, and 2 CFV stenoses requiring reintervention. One iliac vein rupture treated with a stent graft thrombosed. Of 14 patients treated with the contemporary techniques, 2 (14%; P = .006) had major complications: 1 bleed and 1 infected seroma. One intraoperative iliac vein rupture, treated with a second stent relining the first, remains patent. ConclusionsContemporary hybrid operative techniques for incapacitating post-thrombotic iliofemoral and vena caval obstruction increase procedural success and reduce complications compared with the initial approach. The contemporary techniques are recommended for patients undergoing hybrid operative management of post-thrombotic iliofemoral and vena caval occlusion involving the CFV.
