Aneurysms associated with arteriovenous fistulas (AVF) are rare but can cause significant morbidity. They are often diagnosed after rupture, pain, or embolization. We describe a unique case of a 35-year-old woman with a large iliac vein aneurysm related to an acquired AVF incidentally discovered on ultrasound during pregnancy. She had a diagnosis of "idiopathic" pulmonary hypertension for several years. This report details the diagnosis and treatment with an arterial stent graft that was effective in decreasing the size of the venous aneurysm and reversing the systemic changes associated with the disease...

OBJECTIVES: The primary aim was to investigate whether stenting of post-thrombotic iliofemoral obstruction reduces venous hypertension. The secondary aim was to establish whether improvement in haemodynamic parameters impacts on quality of life. METHODS: In this prospective observational study, 12 participants with unilateral post-thrombotic obstruction of the iliac and/or common femoral veins (CFVs) underwent a treadmill stress test with invasive pressure measurements in the CFVs and dorsal foot veins of both affected and non-affected limbs...

PURPOSE: To describe acute venographic changes of external iliac vein (EIV) after ipsilateral common iliac vein (CIV) stent placement. MATERIALS AND METHODS: Retrospective review was performed of 17 cases with placement of a single CIV stent. Central CIV stent diameter and minimal ipsilateral EIV diameter were measured on venogram; vein diameter was measured at the same 2 anatomic locations on venogram obtained before intervention. Relative CIV diameter increase was defined as the ratio of change in central CIV diameter after stent placement to CIV diameter before intervention...

May-Thurner syndrome (MTS) is a rare cause of deep venous thrombosis (DVT) and occurs due to an anatomic anomaly which produces chronic compression of the left common iliac vein by the overlying right common iliac artery when it passes between the right common iliac artery and the spine. Prolonged compression on the vein potentiates thrombus formation by impairing the intima and by leading to the development of membranes within the lumen that may decrease and/or block venous flow. In this case presentation, we elaborate upon a case of a 43-year-old woman who presented with worsening left leg swelling and pain...

Iliocaval thrombosis, or thrombosis of the inferior vena cava and iliac veins, is associated with significant morbidity in the form of limb-threatening compromise from phlegmasia cerulean dolens, development of post-thrombotic syndrome, and death secondary to pulmonary embolism. Endovascular iliocaval reconstruction is an effective treatment for iliocaval thrombosis with high levels of technical success, favorable clinical outcomes and stent patency rates, and few complications. It is often able to relieve the debilitating symptoms experienced by affected patients and is a viable option for patients who fail conservative management...

OBJECTIVE: Iliac vein stenting is increasingly being used in the treatment of venous insufficiency for patients with nonthrombotic iliac vein lesions (NIVL). We have noticed that many stents do not deploy to the expected stent area as designated by the manufactured diameter. The purpose of this study was to evaluate the dynamics of Wallstent® expansion in the iliocaval system. METHODS: Retrospective analysis of all patients with NIVL who were treated with iliac vein stenting using Wallstents®...

Iatrogenic iliac vein dissection secondary to femoral artery puncture is a rare complication that has not yet been documented. A 55-year-old woman presented to our institution with acute right iliofemoral thrombosis 2 weeks after transfemoral cerebral angiography. She was previously healthy and was not taking any medication. Right iliofemoral vein dissection was diagnosed by computed tomography angiography and confirmed by conventional venography. The patient was treated endovascularly with stent insertion, and the venous outflow was patent on the 6-month follow-up computed tomography angiogram...

PURPOSE: To investigate the incidence and potential causes of contralateral deep vein thrombosis (DVT) after common iliac vein (CIV) stent placement in patients with May-Thurner syndrome (MTS). MATERIALS AND METHODS: Data of 111 patients (women: 73%) who had CIV stent implantation for symptomatic MTS at a single center were retrospectively analyzed. Mean patient age was 63.1 ± 15.2 years. Median follow-up was 36 months (range, 1-142 months). Stent location was determined by venogram and classified as extended to the inferior vena cava (IVC), covered the confluence, or confined to the iliac vein...

Resection of the inferior vena cava (IVC) is a rare surgical technique that is occasionally combined with nephrectomy in the setting of renal malignancy with intravascular tumor extension. While this may be fairly well tolerated in some patients due to extensive collateralization in the venous system, there is a clear potential for lower extremity venous insufficiency and deep vein thrombosis (DVT). This report describes a patient who underwent right nephrectomy and segmental IVC resection from the subhepatic space to the iliac confluence, which was complicated by profoundly symptomatic lower extremity DVT and gastrointestinal hemorrhage due to system-to-portal shunting...

INTRODUCTION: Phlegmasia cerulea dolens (PCD) is a rare complication of deep venous thrombosis (DVT). Massive ileo-femoral DVT is usually the cause and prompt treatment is mandatory as it represents a medical emergency. Reported amputation rates range from 12% to 25% and mortality ranges from 25% to 40%. Limb ischemia results from obstruction to arterial inflow secondary to extreme levels of venous hypertension. Primary treatment goal is restoration of venous outflow and can be achieved by endovascular or surgical techniques...

Symptomatic obstruction related to malignant involvement of large veins may occur in central veins both in the thoracic and pelvic regions, and in the abdominal region of the body. Both cases represent a therapeutic challenge, and endovascular revascularization, consisting of angioplasty and stent placement, is safe and effective. Superior vena cava stenting has become widespread in the management of occlusive venous disease. The percutaneous placement of large expandable metal stents allows rapid restoration of normal blood flow in the majority of patients, thus improving symptoms...

BACKGROUND: Occlusion of the inferior vena cava (IVC) often causes venous claudication, leg swelling, or skin changes. We hypothesized that the outcome of nitinol stents for endovascular reconstruction of the IVC is similar to the outcome reported for steel alloy stents. METHODS: From the prospective Bern Venous Stent Registry, we investigated technical success, patency rates, and clinical outcome in consecutive patients with endovascular IVC reconstruction. During routine follow-up visits, stent patency was assessed by duplex ultrasound...

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...
