Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a torso hemorrhage control technique. To expedite deployment, inflation is frequently performed as a blind technique with minimal imaging, which carries a theoretical risk of aortic injury. The objective of this study was to examine the relationship between balloon inflation, deformation and the risk of aortic rupture. Methods: Compliant balloon catheters were incrementally inflated in segments of cadaveric swine aorta...

We experienced 2 cases of primary pulmonary vein stenosis(PVS),which developed after a bidirectional Glenn procedure was performed for complex heart defects with normal pulmonary venous return. Although the patients successfully underwent primary sutureless repair for left PVS, restenosis of the affected pulmonary veins occurred several months after surgery in both patients. Stent implantation followed by balloon angioplasty was performed for stent stenosis in 1 patient without effect. However, the patient later underwent a successful fenestrated Fontan procedure...

BACKGROUND: Vasospasm is a major cause of morbidity and mortality in patients following aneurysmal subarachnoid hemorrhage (SAH). Although early treatment of ruptured aneurysms is advocated, delayed intervention complicates the treatment strategy and leading to significant vasospasm and a poor prognosis. We report our experience of endovascular protocol for occlusion of the unsecured aneurysm and angioplasty for vasospasm in a single session. METHODS: A total of 24 cases with significant vasospasm and unsecured ruptured cerebral aneurysm were reviewed among 660 aneurysmal SAH patients between January 2011 and May 2017...

REVIEW
Richard Lee, Claus Roehrborn
Transurethral resection of the prostate (TURP) is considered the gold standard for minimally invasive treatment of lower urinary tract symptoms due to benign prostate enlargement of <80ml. Although durable and effective, TURP carries the risk of significant side effects, including infection and bleeding, and the risk of dilutional hyponatremia. The Aquabeam system uses high-velocity water jets to robotically ablate prostatic tissue under real-time ultrasound guidance, with hemostasis achieved via a catheter balloon tamponade and a novel traction device or electrocautery...

Brain death (BD) affects organs by multiple mechanisms related to hemodynamic effects, hormonal changes, and the systemic inflammatory response, which reduce organ function and viability. BD reduces microcirculatory perfusion in rat mesentery; this disturbance is also observed in the pancreas and lungs. Sex hormones can affect microcirculatory function, altering tissue perfusion and influencing the inflammatory process. Here, we present differences between sexes in the microcirculatory alterations generated by BD and in inflammatory infiltrate...

Closed vascular injuries have danger of developing critical tissue ischemia with a high risk of amputation and limb loss. However, limited effective strategies exist at present. In this study, we investigate the role of hepatocyte growth factor (HGF) on apoptosis of vascular endothelial cells (VECs). First, apoptosis of VECs was induced by hypoxia treatment with or without HGF. Annexin V-7AAD apoptosis assay revealed that HGF overexpression significantly reduced VEC apoptosis. Then a closed peripheral vascular injury animal model was created by balloon catheter in female New Zealand rabbit...

Intra-abdominal injury is an uncommon complication of chest tube insertion. A 66-year-old man had empyema and underwent chest tube insertion for drainage. Massive hemorrhage occurred; the postprocedural radiograph showed the malpositioned chest tube in the mediastinum. Computed tomography scan showed that the tube's tip penetrated through the liver capsule and passed through the hepatic vein to the right ventricle. Hepatic tract embolization with coiling was performed during chest tube removal under a controlled condition with the hepatic tract occluded by a balloon catheter...

BACKGROUND: The treatment of pediatric sinusitis continues to be a controversial topic. It has been recommended to treat pediatric chronic rhinosinusitis (CRS) with adenoidectomy before proceeding to more invasive techniques. There are concerns regarding side effects of endoscopic sinus surgery in pediatric patients. With the advent of balloon catheter dilation (BCD) as a minimally invasive technique, some authors are recommending up front adenoidectomy with BCD in order to maximize disease resolution while minimizing risk...

INTRODUCTION: Endovascular aortic interventions are suitable alternatives to open surgery, being less invasive and having lower mortality and complications. Accurate positioning of the stent graft is a critical point because of systolic thrush. Techniques used to prevent it include pharmacological (antihypertensive drugs, nitroglycerin, adenosine) and mechanical methods (temporary caval occlusion by balloon). Rapid Right Ventricular Pacing (RRVP) is an emerging alternative with good patient tolerance and low level of complications...

INTRODUCTION: Intravascular or catheter embolization of a foreign body, either by fracture or migration, is a rare condition, occurring in approximately 1%. This study is focused on the migration of catheters since they represent the majority of cases of embolization. We present one of the largest published series of removal of foreign bodies with endovascular techniques. The objective of the present study is to demonstrate the different locations where foreign bodies, in most cases catheters, can reach, the technique used to remove them and the affected population...
