Simultaneous embolization of the right portal and hepatic veins before intrahepatic cholangiocarcinoma resection.

Major liver resections require extensive margins. Occasionally, insufficient parenchyma is available after surgery to maintain liver function. In such cases, vascular embolization in the affected lobe is necessary to induce contralateral lobe hypertrophy.

Use of bacterial cellulose film for repair of bile duct injury in pigs.

Background/objective: The aim was to evaluate the use of bacterial cellulose film and bile duct autograft in repairing critical common bile duct injury in pigs.

Methods: A prospective experimental analytical study was carried out on 20 Sus Domesticus, Piau suidae swine, divided into a control group ( = 10) and an experimental group ( = 10) divided into two subgroups: bacterial cellulose film E1 and bacterial cellulose film E2 to which bacterial cellulose film was randomly allocated. The control group underwent two complete critical common bile duct sections 10 mm apart, while the experimental group with a single critical common bile duct defect underwent a 10 mm section of the longitudinal shaft with edge resection.

Bacterial cellulose biopolymer film and gel dressing for the treatment of ischemic wounds after lower limb revascularization.

Objective: to evaluate the use of a bacterial cellulose biopolymer film and gel dressing in the treatment of patients with ischemic wounds submitted to lower limb revascularization.

Methods: we conducted a randomized clinical trial in the Angiology and Vascular Surgery outpatient clinic of the Clinics Hospital of the Federal University of Pernambuco, between January 2017 and December 2018. We followed 24 patients after lower limb revascularization, divided into two groups: Experimental, treated with bacterial cellulose biopolymer film and gel, and Control, treated with essential fatty acids.

Cerebellar Tonsillar Cysts Associated with Chiari Malformation in Adults: A Short Series.

Background: Authors analyzed surgical patients with Chiari malformation (CM) associated with cerebellar tonsillar cyst. This association is quite rarely encountered in the literature.

Case Description: We retrospectively reviewed 60 surgical adult patients with MRI evaluation who underwent posterior fossa decompression for treatment of CM type I.

Embolization as the Primary Treatment for Mandibular Arteriovenous Malformations: An Analysis of 50 Literature Reports and of an Illustrative Case.

Purpose: The aim of the present report is to describe 50 cases in the literature of mandibular arteriovenous malformations (AVMs) in which embolization was the primary treatment and to discuss details such as age, gender, materials used, outcome of embolization, time of follow-up, and intra- or postprocedure complications. An illustrative case in which reossification was noticed after embolization also is presented.

Patients And Methods: The study was carried out in 2 steps.

Cranial venous sinus dominance: what to expect? Analysis of 100 cerebral angiographies.

Methods: Data of 100 cerebral angiographies were retrospectively analyzed (p = 0.05).

Results: Mean age was 56.

Modified technique for preparation of venous circulation resin casts in the cirrhotic liver.

This study describes two major adaptations for the preparation of resin casts in human cirrhotic liver, harvested at the time of transplantation. The first is the way of fixing the catheter in the ostia of the hepatic and portal veins through a cerclage, so as to prevent displacement of the catheter and / or leakage of the resin during its injection. The second is the extension of corrosion time in the NaOH solution, averaging 6.

Unusual lesions that distend the knee joint: pictorial essay.

The high number of knee imaging exams at radiology clinics, together with the wide variety of knee disorders, calls for expanding the knowledge about the less common lesions seen in routine diagnostic practice. The purpose of this pictorial essay was to illustrate unusual lesions that distend the knee joint, selected by relevance and evaluated with multiple imaging modalities, including X-ray, computed tomography, and magnetic resonance imaging, as well as to perform a brief review of the literature.

Association between ankle-brachial index and carotid atherosclerotic disease.

Background: The association between the ankle brachial index (ABI) and the measurement of intimal medial thickness (IMT) has not been fully studied.

Objective: We aimed to evaluate whether the prevalence of carotid atherosclerosis was higher in patients with ABI < 0.9 than in those with ABI > 0.

Cluster headache and intracranial aneurysm.

In the present study we describe the cases of two patients with cluster-like headache related to intracranial carotid artery aneurysm. One of these patients responded to verapamil prescription with headache resolution. In both cases the surgical clipping of the aneurysm resolved the cluster pain.

Dural sinus compartment in dural arteriovenous shunts: a new angioarchitectural feature allowing superselective transvenous dural sinus occlusion treatment.

Background And Purpose: The dural sinus occlusion has been shown to be effective in the treatment of some dural arteriovenous shunts (DAVS). No long-term results are available, however, regarding the significance of occlusion of a dural sinus. If the disease will stop or if other events will occur later in the remaining sinuses are not well known yet.
