Dorso Proximal Interphalangeal Island Flap.

Background: This study aimed to demonstrate the clinical application of the dorsoproximal interphalangeal island flap as an alternative approach to skin graft or cross-finger flap to repair lesions at the ventral site at the proximal interphalangeal (PIP) finger joint.

Methods: Fifteen patients received flaps (11 men and four women, n = 25 flaps). The repair of volar contracture in finger sequelae after burn injuries was the main indication.

Endovascular Removal of Intravascular Foreign Bodies: A Single-Center Experience and Literature Review.

Objective: To describe causes, clinical signs, experience and endovascular techniques for extraction of intravenous foreign bodies (IFB) and literature review.

Methods: This retrospective study was based on data collected from the medical records of 51 consecutive patients (26 women and 25 men) treated from July 2007 to May 2020 at a single quaternary center in Brazil and case series with data, published in the literature since 2000 on IFB removal, of at least 5 patients. The average patient age was 43.

Mitochondrial K Transport: Modulation and Functional Consequences.

The existence of a K cycle in mitochondria has been predicted since the development of the chemiosmotic theory and has been shown to be crucial for several cellular phenomena, including regulation of mitochondrial volume and redox state. One of the pathways known to participate in K cycling is the ATP-sensitive K channel, MitoK. This channel was vastly studied for promoting protection against ischemia reperfusion when pharmacologically activated, although its molecular identity remained unknown for decades.

Percutaneous retrieval of intravascular foreign body in children: a case series and review.

Background: Percutaneous retrieval of intravascular foreign bodies has recently increased as a treatment option.

Purpose: To report our single-center experience of the percutaneous retrieval of 14 intravascular embolized catheter fragments in children and to conduct a literature review.

Material And Methods: MEDLINE databases were searched for case reports and series including children and iatrogenic catheter fragments or guidewires retrieved through percutaneous techniques.

Soil sample conservation from field to lab for heterotrophic respiration assessment.

We evaluated (1) whether the sample transport time could lead to a significant loss of carbon through microbial respiration and to a change of measured respiration rates, which can be a problem in areas difficult to access, with a long travel time from field to laboratory; (2) whether the method used to quantify heterotrophic respiration for agricultural soils is adequate for horizons that remain always water-saturated or close to saturation. Surface horizons and deep Bh of Amazonian podzols were sampled and kept under refrigeration to maintain moisture of sampling time. Incubations of aliquot of the same sample were initiated on the sampling day and 3, 6, 9 and 12 days after sampling.

Retrievable celect™ filter placement in the superior vena cava: A case report.

Introduction: Venous thromboembolism is an important cause of morbidity and mortality in the world. Upper Extremity Deep Venous Thrombosis (UEDVT) may be a cause of pulmonary embolism. Anticoagulation is the treatment of choice for venous thromboembolism, which is associated with low hemorrhagic complications.

RECOMMENDATIONS FOR INVASIVE PROCEDURES IN PATIENTS WITH DISEASES OF THE LIVER AND BILIARY TRACT: REPORT OF A JOINT MEETING OF THE BRAZILIAN SOCIETY OF HEPATOLOGY (SBH), BRAZILIAN SOCIETY OF DIGESTIVE ENDOSCOPY (SOBED) AND BRAZILIAN SOCIETY OF INTERVENTIONAL RADIOLOGY AND ENDOVASCULAR SURGERY (SOBRICE).

Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications.

Superselective Transcatheter Arterial Embolization in the Treatment of Angiodysplasia.

Acute nonvariceal upper gastrointestinal hemorrhage is a frequent condition associated with significant morbidity and mortality. Angiodysplasia is a common cause of bleeding in the gastrointestinal tract in the elderly. This case report discusses about a 75-year-old woman clinically stable with melena for 2 years due to arteriovenous fistula of upper mesenteric artery branches without adequate clinical and therapeutic treatment.

Peristomal variceal bleeding treated by coil embolization using a percutaneous transhepatic approach.

Peristomal variceal bleeding due to portal hypertension is an entity that has rarely been reported with 3%-4% risk of death. A 68-year-old woman who had undergone a palliative colostomy (colorectal carcinoma) presented with a massive hemorrhage from the colostomy conduit. Considering her oncological status with medial and right hepatic veins thrombosis due to liver metastasis invasion, an emergency transhepatic coil embolization was successfully performed.

Treatment of Skin Depression with Combined Upward Suture Traction and Percutaneous Subcision.

Unlabelled: Scar retraction and soft-tissue depression may compromise aesthetics and cause social embarrassment. The purpose of this study was to evaluate the results of treating soft-tissue depressions or retractions at varied anatomy regions with combined upward suture traction and percutaneous subcision.

Methods: There were 40 patients (age: mean, 39 years; range, 22-55 years; 39 women and 1 man) (total, 77 soft-tissue lesions) who had treatment with the present technique from 1996 to 2013.

An experimental model for the treatment of lethal bleeding injury to the juxtahepatic vena cava with stent graft.

Background: Juxtahepatic vein injuries present a high mortality rate. Our objectives were to develop an experimental model of endovascular lethal injury of the juxtahepatic inferior vena cava (JHIVC) and to evaluate its hemodynamic alterations; to treat the lesion with volume replacement, and a stent graft (SG); and to follow the animals after treatment.

Methods: Twenty dogs were anesthetized and monitored [heart rate (HR), mean arterial pressure (MAP), vesical and peritoneal pressures], and submitted to a JHIVC endovascular injury.

Left hemidiaphragmatic mobility: assessment with ultrasonographic measurement of the craniocaudal displacement of the splenic hilum and the inferior pole of the spleen.

Objective: The purpose of this study was to evaluate the correlation between the radiographic and ultrasonographic measurements of craniocaudal displacement of the left hemidiaphragm.

Methods: Forty-nine patients with clinical indications for interventional procedures prospectively underwent radiographic evaluation of left hemidiaphragmatic mobility and B-mode ultrasonographic measurement of craniocaudal displacement of the hilum and the inferior pole of the spleen. Ultrasonography was performed with a 3.

Right hemidiaphragmatic mobility: assessment with US measurement of craniocaudal displacement of left branches of portal vein.

Purpose: To evaluate the correlation and agreement between ultrasonographic (US) measurement of craniocaudal displacement of the left intrahepatic branches of the portal vein and radiographic measurement of right hemidiaphragmatic mobility.

Materials And Methods: Fifty-one patients with indications for abdominal angiography or percutaneous cholangiography prospectively underwent radiographic evaluation of right hemidiaphragmatic mobility and B-mode US measurement of craniocaudal displacement of the left intrahepatic branches of the portal vein. US was performed by using a 3.
