BACKGROUND: Symmetrical peripheral gangrene is characterized as acral (distal extremity) ischemic limb injury affecting two or more extremities, without large vessel obstruction, typically in a symmetrical fashion. Risk factors include hypotension, disseminated intravascular coagulation, and acute ischemic hepatitis ("shock liver"). In contrast, venous limb gangrene is characterized by acral ischemic injury occurring in a limb with deep vein thrombosis. Both symmetrical peripheral gangrene and venous limb gangrene present as acral limb ischemic necrosis despite presence of arterial pulses...

Local symptoms of chronic venous insufficiency after deep vein thrombosis (DVT) are well described, but little is known about the effect of residual venous obstruction on exercise capacity. We tested our hypothesis that chronic residual iliofemoral vein occlusion (IFVO) after DVT may impair exercise capacity. Nine post-DVT patients with residual IFVO and effort intolerance were studied; a comparison cohort consisted of 11 healthy volunteers. Exercise tolerance was assessed by bimodality incremental symptom-limited cardiopulmonary testing, using leg and arm ergometers...

Endovascular stent placement for chronic postthrombotic iliofemoral venous obstructive lesions is an effective therapeutic option and might be complicated by stent migration. We report a case of a venous stent that was lost from the iliac vein into the right ventricle rescued by emergent open-heart surgery.

Postthrombotic syndrome (PTS) is the most common complication after iliofemoral deep vein thrombosis. It reduces quality of life and increases deep vein thrombosis (DVT)-related costs. The clinical symptoms and severity of PTS may vary; the most common symptoms include edema, pain (venous claudication), hyperpigmentation, lipodermatosclerosis, and ulceration. PTS is based on the principle of outflow obstruction, which may be caused by venous hypertension and may lead to valvular damage and venous reflux or insufficiency...

Venous stenting for CVD is being increasingly used as more evidence accumulates supporting the open vein hypothesis and supporting the safety, efficacy, and durability of these interventions. As such, they can be offered to patients with advanced age and complex comorbidities. Future studies should focus on reporting outcomes specific to the underlying venous pathologic condition (thrombotic vs nonthrombotic and acute vs chronic) to provide better evidence for stenting in CVD, and the outcomes of new stent design with dedicated venous indications...

BACKGROUND: Combination treatment with percutaneous endovenous intervention (PEVI) and anticoagulation has been proposed for treating lower-extremity proximal deep vein thrombosis (DVT). We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effect of PEVI plus anticoagulation versus anticoagulation alone in patients with lower-extremity proximal DVT. METHODS: We systematically searched PubMed, Embase, and the Cochrane Library from inception to May 2016...

Background Endovascular recanalisation of chronic obstruction of iliofemoral or caval veins gives very good patency. However, patency decreases if the common femoral vein and its side branches are also involved. Endophlectomy during a hybrid procedure can improve outcome and avoid early reocclusion due to restored inflow. The review presents the technical details and the published results of this technique. Results The hybrid procedure combines venous recanalisation and stent angioplasty with endophlebectomy...

Current national and international guidelines recommend endovascular therapy of iliofemoral thromboses in young patients, as a treatment option to avoid the post-thrombotic syndrome. Possible techniques include endovascular local lysis therapy, as well as pharmacomechanical or purely mechanical procedures. Endovascular therapy of chronic obstruction of the inferior V. cava or pelvic veins is an effective therapy for patients suffering from post-thrombotic syndrome. If there is involvement of the V. femoralis communis, hybrid operations may be considered in which an AV fistula is formed or endophlebectomy is carried out...

BACKGROUND: Patients with iliofemoral deep venous thrombosis are at risk for development of post-thrombotic syndrome. Iliac vein stenting has been shown to significantly improve clinical outcomes in patients with venous outflow obstruction, although many studies include a heterogeneous population with several different venous pathologic processes. Our objective was to evaluate the results of iliocaval and infrainguinal venous intervention for venous outflow obstruction due to post-thrombotic chronic venous occlusive disease...

BACKGROUND: Selecting patients for iliofemoral vein stenting has traditionally relied on the identification and quantification of stenotic lesions with imaging such as multiplanar venography. Recently, intravascular ultrasound (IVUS) imaging has become more available. However, to date, the usefulness of these imaging modalities using the customary >50% treatment threshold for diameter (multiplanar venography) and area (IVUS) stenosis of iliofemoral veins has not been validated prospectively within the context of clinical improvement...

OBJECTIVE: To assess the first results of hybrid operations in chronic venous obstructions of iliofemoral segments in patients with postthrombotic syndrome (PTS). METHODS: Hybrid operations (open endovenectomy from the common femoral vein with arteriovenous fistula creation and iliac vein stenting) were performed in 12 patients diagnosed with PTS. All of the patients were diagnosed with severe chronic venous insufficiency. The degree of manifestations of PTS was assessed by means of the Villalta score 7 months before and after the surgical intervention...

Introduction Venous recanalization of obstructed femoral and iliac veins is associated with good results regarding the feasibility and patency rate. If the common femoral vein with its inflow vessels is involved, open surgical desobliteration or endophlebectomy has been described as a crucial part of the intervention. However, when performing the hybrid procedure, a number of specific complications have been described. We present our results after venous recanalization including an endophlebectomy, focussing on wound complications and its impact on outcome...

Post-thrombotic syndrome secondary to iliofemoral deep venous thrombosis is a significant contributor to advanced chronic venous insufficiency. Iliac vein stenting is a standard procedure to treat iliocaval obstruction. In cases with obstruction extending across the groin, venous inflow for an iliac vein stent may be poor and compromise results of iliac vein stenting. Treatment options include extension of stents across the inguinal ligament that may have limitations in improving inflow only from only one vessel...
