Multifocal Sarcoma Mimicking Superficial Vein Thrombosis of the Leg: A Case Report.

BACKGROUND Leiomyosarcoma is a common tumor found in soft tissue. In relation to the vascular system, leiomyosarcoma appears as the most common malignancy characterized by poor prognosis. Leiomyosarcomas of the leg large vessels often occur late, and their appearance can imitate vein thrombosis with symptoms such as soft tissue swelling or mild pain, and can be misdiagnosed.

Undersized Stentgraft Placement for Traumatic Descending Aorta Rupture, and What Is Next?

BACKGROUND Traumatic injury of the thoracic aorta is proving to be not only the most lethal of traumatic injuries, but also the most urgent reason for vascular intervention among all trauma patients. Endovascular aortic repair is used increasingly often to treat traumatic injuries. We report a case of endovascular treatment and its use as a delayed correction (two-stage treatment) for a traumatic aortic isthmus rupture.

Three-Dimensional Volumetric Renal Reconstruction Based on Geometrical Coefficients.

The article presents an innovative method of 3D computer tomography (CT) image reconstruction of kidney. Diagnosis based on CT scanning allows to obtain projections of multi-dimensional object, made from different directions in order to create cross-sectional (2D) slices. Standard techniques for identifying kidneys in CT images analyze each 2D slice separately.

Intra-Aortic Balloon Pump Catheter Insertion Using a Novel Left External Iliac Artery Approach in A Case of Chronic Heart Failure Due to Dilated Cardiomyopathy.

BACKGROUND The use of an intra-aortic balloon pump (IABP) in patients with advanced heart failure can provide interim mechanical support as a bridge to further treatment, including cardiac transplantation. The femoral artery, axillary artery, and subclavian artery are the main approaches to IABP catheter placement. A case is reported of the use of a left external iliac artery approach to IABP catheter placement using a subcutaneous channel in a patient with chronic heart failure.

Absence of inferior vena cava in 14-year old boy associated with deep venous thrombosis and positive Mycoplasma pneumoniae serum antibodies--a case report.

Background: Absence of the inferior vena cava is a rare vascular anomaly, which usually remains asymptomatic in childhood. It is recognized as the risk factor for deep venous thrombosis, since the collateral circulation does not provide adequate drainage of the lower limbs. Mycoplasma pneumoniae is a common cause of community-acquired pneumonia in school-aged children and adolescents.

Computerized System for Quantitative Assessment of Atherosclerotic Plaques in the Femoral and Iliac Arteries Visualized by Multislice Computed Tomography.

Objective: The investigation is aimed at the development of a semiautomatic method of examining the femoral and iliac arteries, and quantifying atherosclerotic plaques visible in the multislice computed tomography images.

Methods: We have utilized the advanced morphology and segmentation methods for processing of a series of the images. In particular, a novel sorted pixel intensity approach to segment the artery into the lumen/plaque regions has been used, and effectively combined with the Gaussian mixture modeling to increase the accuracy of the segmentation.

Lymphatic complications after vascular interventions.

Introduction: Lymphorrhea due to classical and mini-invasive surgical interventions on femoral and popliteal arteries is a serious hindrance to patient treatment. Depending on the experience of a particular center, the incidence and frequency of this type of complication may constitute a serious clinical problem. While the level of lymphorrhea intensity and its duration result in certain foreseeable consequences, their treatment can be a time-consuming and multistep procedure.

New surgical modification of fascial closure following endovascular aortic pathology repair.

Introduction: There are clear benefits of percutaneous versus open femoral access for endovascular aortic pathology repair. All closing devices commercially available are expensive. Surgical closure of the femoral artery risks potential prolonged wound healing and as a consequence longer hospital stay.

Morphological evaluation of the iliac and femoral arteries; possibilities and perspectives.

Unlabelled: The study presented an approach to the morphometric image of atherosclerotic lesions of the final segment of the abdominal aorta, femoral and iliac arteries, considering possible endovascular intervention. The evaluation of these arteries is very important, because they are often used as a point of access for endovascular procedures performed on the peripheral arteries, or within the thoracic and abdominal aorta and its branches, as well as coronary arteries. The aim of the study was to determine morphometric measurements describing the atherosclerotic lesions, including the methodology of their surgical interpretation.

[Heart failure as an independent prognostic factor for endovascular method of abdominal aortic aneurysm treatment].

Endovascular aneurysm repair (EVAR) has been accepted as an alternative to traditional open surgery in selected patients. Now it is a widely accepted standard. In case of contraindications for open repair, after accomplishing including criteria for EVAR, the patient can be treated by this method.

[The case of an acute thoracic aorta dissection in the patient with Marphan syndrome].

Acute thoracic aorta dissection is one the most dangerous pathology of aorta. If left untreated, is associated with high mortality. Early diagnosis and proper treatment improves outcomes.

Transcatheter aortic valve implantation using transfemoral/transsubclavian or transapical approach: 30-day follow-up of the initial 30 patients.

Background: Transcatheter aortic valve implantation (TAVI) is a new method for the treatment of aortic stenosis (AS).

Aim: To evaluate early results of TAVI using transfemoral/transsubclavian approach (TFA/TSA) or transapical approach (TAA) in patients with severe AS and high risk for surgical aortic valve replacement.

Methods: Between January 2009 and May 2010, 30 high-risk patients underwent TAVI.

Peritoneal dialysis as a therapeutic approach in congestive heart failure resistant to pharmacological treatment: case report.

This report describes the use of continuous peritoneal dialysis (PD) as an alternative to hemodialysis (HD) in a patient with type 2 cardiorenal syndrome in the course of congestive heart failure resistant to standard pharmacological treatment. A 39-year-old man presented with a 24-year history of progressive heart failure. Ineligibility for heart transplant and previous inefficient treatment with different modifications of HD reduced his treatment options to PD.
