The Transbrachial Venous Approach for Pelvic Congestion Syndrome Embolization: An Easy Way to Outpatient Procedure.

Background: Pelvic congestion syndrome (PCS) is a frequent finding in adult women and transcatheter embolization of dilated and refluxing veins is the treatment of choice. The procedure can be performed through different venous accesses such as the transfemoral, transjugular, and the transbrachial access. The aim of this study was to demonstrate the feasibility and safety of the transbrachial approach for transcatheter embolization in this pathology in 201 women.

Atypical Renal Artery Preservation with an Iliac Branch Device in an Infrarenal Abdominal Aortic Aneurysm.

Anatomical variations of the renal arteries may complicate endovascular repair of infrarenal abdominal aortic aneurysms (AAA). Occlusion of renal branches may be necessary to seal the aneurysm sac efficiently. Depending on the size of the affected renal arteries and the supplied parenchyma, this can lead to loss of renal function.

Investigation of chitosan's antibacterial activity against vancomycin resistant microorganisms and their biofilms.

Vancomycin-resistant microorganisms are a hurdle that traditional antibiotics struggle to overcome. These difficulties have led to search for new solutions based on natural products. Chitosan has been recognized as an effective antibacterial agent against a vast array of microorganisms including antibiotic resistant ones.

DNA agarose gel electrophoresis for antioxidant analysis: Development of a quantitative approach for phenolic extracts.

Most of the fast in vitro assays proposed to determine the antioxidant capacity of a compound/extract lack either biological context or employ complex protocols. Therefore, the present work proposes the improvement of an agarose gel DNA electrophoresis in order to allow for a quantitative estimation of the antioxidant capacity of pure phenolic compounds as well as of a phenolic rich extract, while also considering their possible pro-oxidant effects. The result obtained demonstrated that the proposed method allowed for the evaluation of the protection of DNA oxidation [in the presence of hydrogen peroxide (HO) and an HO/iron (III) chloride (FeCl) systems] as well as for the observation of pro-oxidant activities, with the measurements registering interclass correlation coefficients above 0.

[Primary mechanical thrombectomy for acute occlusions of cerebral arteries].

Cerebral ischemia due to occlusion of the principal intracranial arteries is a significant cause of morbidity and mortality. New devices for mechanical thrombectomy can facilitate rapid extraction of the thrombus. This paper describes the results of primary mechanical thrombectomy with the Solitaire revascularization device without intravenous fibrinolysis.

Chimney and periscope grafts to facilitate endovascular treatment of aortic transection in a patient with aberrant right subclavian artery.

Purpose: To report the use of parallel grafts to extend the proximal landing zone for stent-graft repair of aortic transection involving an aberrant right subclavian artery (ARSA).

Case Report: A 28-year-old patient was referred for treatment of traumatic aortic transection with contained rupture at the level of an ARSA. Immediate thoracic endovascular aortic repair (TEVAR) was planned because of hemodynamic instability.

Leiomyosarcoma of the deep femoral vein. A rare cause of venous obstruction in lower limbs and an alternative diagnosis to chronic venous thrombus.

Primary venous leiomyosarcoma of the extremities is an uncommon, but aggressive, tumoral entity with a high rate of local recurrence and early hematogenous metastasis. In the present article, we report a case of leiomyosarcoma of the vena profunda femoris. This pathology causes deep venous thrombosis-like symptoms.

Renal embolization and nephrectomy in a single surgical act in high-risk renal tumor pathology.

Background: Renal artery embolization is a procedure that has been shown to be useful as a concomitant treatment for the resection of large renal tumors. Over the years, preoperative renal artery embolization concomitant with nephrectomy as a treatment option has proved to be useful in reducing morbi-mortality rates; however this procedure is not exempt from significant iatrogenia. Performing this technique in conjunction with nephrectomy in a single surgical act helps to maintain the advantages of this treatment, which in turn considerably reduces the associated morbi-mortality rates.
