In ultrasound-guided central venous catheterization, there is no standard technique either for the needle tip visualization or for the adequate needle angle and entry to the skin with short-axis view under out-of-plane technique. In the present study, we propose a novel technique named "stepwise flashing with triangulation", and the efficacy of this technique is assessed. Before and after a didactic session in which the technique was explained, 12 novice residents were asked to position the needle tip on or into the imitation vessels and to avoid deeper penetration by using an agar tissue phantom with ultrasound guidance...

AIMS: To present our technique of suprameatal urethrolysis with Martius flap (SMUM) and outcomes of this procedure for refractory female bladder outflow obstruction (BOO). METHODS: A retrospective chart review was performed to identify female patients who underwent SMUM between January 2010 and August 2016 after failed transvaginal urethrolysis (TVU) for BOO due to prior stress urinary incontinence (SUI) surgery. The primary outcome measure was surgical success defined as patient ability to void volitionally without need for catheterization or additional surgery for BOO...

Most diagnostic testing in patients with anomalous aortic origins of coronary arteries, myocardial bridges, and coronary artery changes after Kawasaki disease are performed with the use of noninvasive techniques. In some cases, however, further diagnostic information is needed to guide the clinician in treating these patients. In such instances, cardiac catheterization with invasive anatomic and functional testing is an invaluable tool. Moreover, interventional treatment in the cardiac catheterization laboratory may be performed in a small subset of these patients...

In the current era, diagnosis and follow-up of valvular heart disease is performed noninvasively using echocardiography. In some cases, the results of echocardiographic evaluation are inconclusive or discrepant with the patient's clinical symptoms. In such cases, a well-planned and executed cardiac catheterization is invaluable to clarify the clinical dilemma and assist in planning further management. This article reviews the indications, technique, and interpretation of cardiac catheterization in the setting of valvular stenosis and regurgitation...

REVIEW
Ganesh Athappan, Paul Sorajja
Pericardial diseases can be classified broadly as 3 entities: acute pericarditis, cardiac tamponade, and constrictive pericarditis. These disorders can be diagnosed and managed with noninvasive studies following a comprehensive history and physical examination, without the need for cardiac catheterization in most patients. Despite the advances in noninvasive cardiac imaging, there are limitations to their diagnostic accuracy. The invasive hemodynamic study offers the advantage of simultaneous, direct pressure measurement across multiple chambers, with direct examination of blood flow...

Rationale Mechanical thrombectomy with a stent retriever is now the standard of care in anterior circulation ischemic stroke caused by large vessel occlusion. New techniques for mechanical thrombectomy, such as contact aspiration, appear promising to increase reperfusion status and improve clinical outcome. Aim We aim at ascertaining whether contact aspiration is more efficient than the stent retriever as a first-line endovascular procedure. Sample size estimates With a two-sided test (alpha = 5%, power = 90%) and an anticipated rate of spontaneous recanalization and catheterization failures of 15%, we estimate that a sample size of 380 patients will be necessary to detect an absolute difference of 15% in primary outcome (superiority design)...

INTRODUCTION: Neurogenic bladder is a common urological condition among elderly. It results in incontinence or retention of the urine depending on the synergy of bladder smooth muscles and urethral sphincter. There can also be a condition where retention causes overflow incontinence. Retention of urine in this condition is caused by relative lack of contractility of bladder smooth muscles in response to the stretch reflex. As a result, there is no urge and therefore the bladder remains over-distended causing retention of urine...

OBJECTIVES: Fetal lower urinary tract obstruction (LUTO), most often associated with presence of posterior urethral valves, poses high risk of perinatal mortality or postnatal renal failure. Looking for a method of causative treatment we have devel-oped a technique of fetal urethroplasty with a coronary angioplasty balloon catheter inserted under an ultrasonographic guidance via an 18-gauge needle introduced transabdominally to fetal bladder. MATERIAL AND METHODS: We have used this procedure in three women with singleton pregnancies (two primiparas and one multipara, 32-35 years of age), diagnosed with fetal megacystis at 12-16 weeks of gestation...

Atrial fibrillation (AF) is a common type of arrhythmia that increases significantly the risk of blood clots in the heart and of stroke. Therefore, stroke prevention is a key goal of AF treatment. In the past, patients were required to take anticoagulants for the remainder of their life, to regularly the monitor international normalized ratio (INR) of prothrombin time (PT), and to avoid possible negative interactions with various drugs and foods. Left atrial appendage occlusion (LAAO), a novel device and technique, was thus developed for AF patients with contraindications to anticoagulants and a high risk of bleeding...

Transjugular intrahepatic portosystemic shunt (TIPSS) has important role in the management of Budd-Chiari syndrome (BCS). Stent dysfunction rate up to 80% at 2 years limits the use of TIPSS. Reintervention is required if shunt develops occlusion or stenosis. Different techniques have been reported for the catheterization of TIPSS in cases of an occluded stent. In those failing a standard transvenous approach, the Colapinto needle technique, a combined transvenous transhepatic approach or transplenic approaches have been described...

A 64-year-old man presented with previous non-ST elevation myocardial infarction and cardiogenic shock. Due to hemodynamic instability, percutaneous coronary intervention (PCI) was performed with implantation of two everolimus-eluting stents by V-stenting technique to LM-LAD and LM-LCX. After 9 months without symptoms, he developed progressive angina. Non-selective LM coronary angiography was performed due to stents protrusion in the aortic root. A 128-slice dual-source coronary CT angiography showed severe LM-LAD stent underexpansion with critical in-stent restenosis at the proximal third...

The Pipeline embolization device (PED) has become a very important tool in the treatment of nonruptured cerebral aneurysms. However, a patient's difficult anatomy or vascular stenosis may affect the device delivery. The purpose of this article was to describe an alternate technique for PED deployment when ipsilateral anatomy is not amenable for catheter navigation. A 44-year-old woman with a symptomatic 6-mm right superior hypophyseal artery aneurysm and a known history of right internal carotid artery dissection presented for PED treatment of her aneurysm...

What is PICC line insertion? The PICC is a soft, flexible catheter which is made of polyurethane or silicone, and is inserted via an upper or lower extremity peripheral vein into superior or inferior vena cava. The origin of PICC line dates back to the early 1950s. Since the introduction of the PICC catheter, this method of venous catheterization has gone through many changes as regards the technique of insertion or the type of catheter used. Despite the routine use of PICC line worldwide, little progress has been made in its use in Hungary...

Central venous catheterization is widely used in the emergency setting. This review aims to assess central venous catheterization from the perspectives of types of catheters, sites of insertion, and techniques. In emergency conditions, non-tunneled catheters are preferred because the technique for its insertion is not complicated and less time-consuming. The size of catheter depends on the purpose of catheterization. For example, a large bore catheter is needed for rapid infusion. The ideal catheterization site should bear fewer thromboses, lower infectious rate, and fewer mechanical complications...

OBJECTIVE: Although the benefits of minimally invasive valvular surgery are well established, the applicability of extending these techniques to reoperative aortic valve surgery is unknown. We evaluated our experience with a minimally invasive approach to this patient population. METHODS: From January 2010 to September 2015, 21 patients underwent reoperative isolated aortic valve replacement via a minimally invasive approach by a single surgeon. All patients had preoperative evaluation with computerized tomography and coronary catheterization...

OBJECTIVE: A retrograde technique through the gap between the distal stent landing zone and the iliac artery wall has been applied to treat type II endoleak after endovascular aortic aneurysm repair (EVAR). In this study, we tried to investigate its efficacy in the management of type III endoleak and intraoperative accidental events. METHODS: We reported 2 complications of EVAR that were difficult to treat with conventional methods. One patient had a sustained type III endoleak after EVAR, and the right renal artery was accidentally sealed by a graft stent in the other patient during the operation...
