Two patients with ventriculoperitoneal shunts presented with symptoms of raised intracranial pressure indicative of possible shunt malfunction. During investigation, to eliminate this possibility, cerebral spinal fluid infusion studies were performed, which indicated proximal occlusion of the shunts in both cases. Retrograde flush of the ventricular catheter was performed during temporary compression of the siphon-control device, a manoeuvre which blocks distal flow. After the use of this technique, both patients' symptoms improved and they have remained symptom-free for over 2 years...

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...

INTRODUCTION: Peripheral intravenous catheters (PIVCs) are frequently used in hospitals. However, PIVC complications are common, with failures leading to treatment delays, additional procedures, patient pain and discomfort, increased clinician workload and substantially increased healthcare costs. Recent evidence suggests integrated PIVC systems may be more effective than traditional non-integrated PIVC systems in reducing phlebitis, infiltration and costs and increasing functional dwell time...

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...

Recent advances in the field of pediatric interventional cardiology have resulted in therapies for patients in need of augmented pulmonary artery (PA) flow. Catheter-based PA rehabilitation can be performed safely but not without the potential risk of pulmonary hemorrhage. When severe, this bleeding has the ability to contaminate the bronchi and trachea, and possibly occlude the endotracheal tube. This can result in a critical inability to ventilate and oxygenate these patients. Herein, we review our institutional experience with pulmonary hemorrhage associated with these procedures and the feasibility of predicting this outcome...

BACKGROUND: The successful recanalization rate of chronic total occlusion (CTO) lesions without retrograde collaterals available is always low. Intravascular ultrasound (IVUS) may be useful to guide the subintimal guidewire to re-enter the true lumen. We evaluated the clinical feasibility and efficacy of the IVUS-guided wiring re-entry technique for these complex CTO lesions. METHODS: Twenty consecutive patients (19 male, mean age: 65.3 ± 12.8 years) with both failed antegrade and retrograde approaches were enrolled...

Restenosis after catheter or surgical intervention substantially affects the prognosis of arterial occlusive disease. Mesenchymal stem cells (MSCs) may have anti-stenotic effects on injured arteries. MSC transplantation from the adventitial side of an artery is safer than endovascular transplantation but has not been extensively examined. In this study, a rat model of femoral artery injury was used to compare the anti-stenotic effects of transplanted cell sheets and transplanted cell suspensions. Rat adipose-derived stem cells (ASCs) were used as the source of MSCs...

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...
