Clinical outcomes of direct oral anticoagulants after lower extremity arterial procedures.

Objectives The use of postoperative anticoagulation is not uncommon for patients undergoing lower extremity arterial procedures as adjunctive therapy. Longer postoperative length of stay is necessary to achieve adequate therapeutic international normalized ratio with traditional protocols that call for the use of unfractionated heparin and warfarin therapy. We hypothesized the direct oral anticoagulants are an attractive alternative to provide adequate anticoagulation in patients who undergo lower extremity arterial procedures.

Safety and efficacy of stenting nonthrombotic iliac vein lesions in octogenarians and nonagenarians in an office setting.

Objectives Treatment options for venous insufficiency are rapidly evolving in the office setting and include venography, intravascular ultrasound, and venous stenting. Non-thrombotic iliac vein lesions assessment and treatment in an office setting is currently an area of interest. The purpose of this study is to demonstrate the safety and efficacy of evaluating non-thrombotic iliac vein lesion with this office-based procedure in octogenarians and nonagenarians.

Endoureteral coil embolization of an ureteral arterial fistula.

Background Ureteral arterial fistulas are rare but potentially life threatening. We present a female who developed a ureteral arterial fistula following a right robotic nephrectomy. After several endovascular interventions to control the bleeding had failed, we approached the fistula through the right ureteral stump with coil embolization.

The bull's eye sign and other suprainguinal venographic findings to limit the use of intravascular ultrasound in patients with severe venous stasis.

Objective: When assessing the common femoral and suprainguinal veins in patients with venous stasis, it is generally agreed that use of intravascular ultrasound (IVUS) is mandatory. This widely held dogma is reinforced by the fact that extrinsic compression of the iliac veins does not reproduce images consistent with eccentric stenosis as one sees in the arterial system. In an attempt to identify a subgroup of patients where the use of IVUS could be averted, we analyzed and carefully evaluated the images of patients who had both standard contrast venograms and IVUS examinations.

Clinical correlation of anatomical location of non-thrombotic iliac vein lesion.

Objective Treatment of non-thrombotic iliac vein lesions is an active area of research. Intravascular ultrasound allows its localization. We chose intravascular ultrasound to clarify the exact anatomical location of non-thrombotic iliac vein lesions and correlate it with clinical findings.

The Clinical Efficacy of Balloon-Assisted Maturation of Autogenous Arteriovenous Fistulae.

Background: Delayed maturation of arteriovenous fistulae (AVF) among patients who require hemodialysis (HD) can lead to catheter sepsis with its resultant morbidity and mortality. Some have proposed that sequential balloon-assisted maturation (BAM) may accelerate the maturation times of these accesses. On the other hand, serial balloon angioplasty of normal vein may result in stenosis and delay maturation.

Management of Acute Isolated Soleal Vein Thrombosis in a Pregnant Patient With an Osteopathic Approach to Evaluation.

In pregnant women, the risk of venous thromboembolism increases 4 to 5 fold over that in nonpregnant women. Deep vein thromboses in the calf occur in approximately 6% of cases, with a 20% incidence of propagation, but new imaging methods suggest a higher rate. Nevertheless, the management of isolated soleal vein thrombosis is currently one of the most debated issues in the field of venous thromboembolism, and a clear set of principles for the management of this unique clinical problem remains undefined.
