Non-cirrhotic portal vein thrombosis - therapeutic challenge.

Portal vein thrombosis (PVT) is a disease in which thrombosis occurs from the intrahepatic branches of the portal vein, and may extend to the splenic vein and/or superior mesenteric vein. It is most often associated with liver cirrhosis. PVT not associated with cirrhosis is rare.

Endovascular treatment of penetrating thoracic aorta injury - case report.

In the current scenario, traumas with violent causes are responsible for large numbers of cases. Among these, thoracic aorta injury caused by penetrating trauma is a cause of elevated morbidity and mortality, demanding adequate diagnosis, and can now often be repaired using endovascular procedures. This treatment method has proven to be safer, with a lower rate of complications than open surgical procedures.

Endovascular treatment of traumatic dissection of the thoracic aorta - series of 16 cases.

Background: Aortic injuries caused by blunt chest traumas have high pre-hospital and emergency mortality. The endovascular approach is one option for treatment of these injuries, but many outcomes related to this approach remain unknown.

Objectives: The aim of this study is to describe a specialist trauma center's experience with endovascular treatment of cases like these.

Axillary-iliac bypass to protect a transplanted kidney during abdominal aortic aneurysm repair: case report.

Abdominal aortic aneurysms (AAA) are the most common type, even when compared to those involving other segments of the aorta. The prevalence and natural history of arterial aneurysms in abdominal organ transplant recipients remain uncertain. We report a case of abdominal aortic aneurysm in a kidney transplant patient with contrast allergy.

Complex treatment of aortic dissection is still a controversial subject because of the severity of these cases and the need to treat on a case-by-case basis. Severity is related to the difficulty of diagnosis caused by nonspecific complaints and by the serious complications inherent to disease progression (aortic rupture, hypoperfusion syndrome, retrograde dissection, refractory hypertension or pain). This article reports the case of a 61-year-old male smoker with poorly controlled hypertension who suffered a Stanford type B aortic dissection.

Laser treatment of venous malformations.

Objective: To evaluate whether treatment of venous congenital vascular malformations with the use of laser technology provides lightening or disappearance of lesions with a high degree of satisfaction reported by patients and observed by the physician.

Methods: A retrospective study gathered 26 patients suffering from vascular malformation, of which 73.07% were female and were treated with the PhotoDerm® device.

An open-label, comparative study of the efficacy and safety of once-daily dose of enoxaparin versus unfractionated heparin in the treatment of proximal lower limb deep-vein thrombosis.

Background: Treatment of deep-vein thrombosis (DVT) with a once-daily regimen of enoxaparin, rather than a continuous infusion of unfractionated heparin (UFH) is more convenient and allows for home care in some patients. This study was designed to compare the efficacy and safety of these two regimens for the treatment of patients with proximal lower limb DVT.

Methods: 201 patients with proximal lower limb DVT from 13 centers in Brazil were randomized in an open manner to receive either enoxaparin [1.
