Ultrasonography is a well-defined and widely accepted technique in the settings of interventional procedures requiring peripheral venous access, either for the confirmation of the vein patency (with the compression test) or for guiding needle insertion. This report describes a case of unsuccessful guidewire passage through the right iliac vein in spite of successful ultrasonography-guided puncture of the femoral vein. On repeat duplex ultrasonography, the Doppler waveform showed a continuous pattern without respiratory phasicity, which was consistent with proximal venous occlusion...

OBJECTIVE: To investigate the feasibility and safety of the peripherally inserted central catheters (PICCs) accessed via the superficial femoral vein in patients with superior vena cava syndrome (SVCS). METHODS: From October 2010 to December 2014, 221 cancer patients with SVCS in our center received real-time ultrasound-guidance of the superficial femoral vein inserted central catheters (FICCs) at the mid-thigh. PICC insertion via upper extremity veins had also been investigated in 2604 cancer patients without SVCS as control...

INTRODUCTION: Various intravesical and extravesical techniques have been described for the surgical correction of vesicoureteral reflux (VUR). Among those techniques Cohen (intra-vesical) and Lich-Gregoir (extra-vesical) are the most commonly used ones. However, there are limited studies that compare those two surgical techniques in the literature. OBJECTIVE: In this study, we aim to compare the outcomes of the open intravesical and extravesical procedures for unilateral primary VUR in children...

Recent advances have been made in the development of microcatheters, and have contributed to super-selective catheterization. One new tool is the triple co-axial (triaxial) system, which consists of a small microcatheter, large microcatheter, and 4- or 5-Fr. catheter. This system may be applied to complex interventions. We herein introduce the technique for and advantages of the triaxial system.

BACKGROUND: Measurement of blood oxygen saturation (O2 saturation) is of great importance for evaluation of patients with many cardiovascular diseases, but currently there are no established non-invasive methods to measure blood O2 saturation in the heart. While T2-based CMR oximetry methods have been previously described, these approaches rely on technique-specific calibration factors that may not generalize across patient populations and are impractical to obtain in individual patients...

Background Dialysis access-associated steal syndrome is a major complication of arteriovenous fistula creation whereby the low-resistance venous conduit shunts arterial inflow through the anastomosis, resulting in clinically significant distal artery insufficiency. Herein, we describe a case of severe steal phenomenon with gangrene of a digit following placement of an arteriovenous fistula that was treated with a novel, entirely endovascular technique. To our knowledge, this was the first totally endovascular approach to dialysis access-associated steal syndrome...

The incidence of complications such as pneumothorax and hematoma between the chest wall-parallel and conventional subclavian venous catheterization in cancer chemotherapy was compared. From December 2011 to March 2016, a total of 314 patients undergoing chemotherapy for cancer in the Guizhou Provincial People's Hospital were assigned to either the Chest Wall-parallel (n=155) or the conventional subclavian venous catheterization group (n=159) in order to observe the primary success rate for catheterization and to assess the incidence of complications such as pneumothorax, hemothorax, hematoma, and internal jugular venous injury...

INTRODUCTION: Peripheral and central blood pressures are parameters of arterial stiffness and important cardiovascular risk markers. Today, there are non-invasive methods that measure these pressures. AIM: To validate the non-invasive oscillometric method, compared with invasive pressure measurements obtained by cardiac catheterization. METHODS: An open, prospective cohort clinical study in 100 patients, 64 ± 11 years old. The measurement of peripheral and central blood pressures obtained using the Arteriograph(®) system oscillometric method, (TensioMed, Budapest-Hungary, Ltd...

The correct choice of intra vascular access in critically ill neonates should be individualized depending on the type and duration of therapy, gestational and chronological age, weight and/or size, diagnosis, clinical status, and venous system patency. Accordingly, there is an ongoing demand for optimization of catheterization. Recently, the use of ultrasound (US)-guided cannulation of the subclavian vein (SCV) has been described in children and neonates. This article gives an overview of the current use of US for achieving central venous catheter placement in the SCV or the brachiocephalic vein (BCV) in neonates...

Iatrogenic aortic dissection is an infrequent complication of cardiac catheterization (0.03-0.06%) associated with up to 19% of mortality at 30 days. It was reported to mostly occur when using a 6-Fr guiding catheter to cannulate the right coronary artery. This life-threatening complication usually requires early surgical management and close imaging monitoring and control of systolic blood pressure. This case report describes a patient with iatrogenic aortic dissection during cardiac catheterization in symptomatic coronary artery disease...

OBJECTIVES: Off-pump bilateral bidirectional Glenn (b-BDG) poses a surgical challenge and may add complexity to the postoperative outcome especially regarding uniformity of the anastomosis and central pulmonary artery growth. Herein, we report early- and mid-term outcomes after off-pump b-BDG without using superior vena cava decompression techniques. METHODS: Ninety-seven consecutive patients, between 2009 and 2014, were included in this prospective study. All patients had complete pre- and postoperative clinical and detailed neurological assessments...

We sought to compare pulmonary flow hemodynamic indices obtained by Fick and thermodilution catheterization techniques with phase-contrast MRI (PC-MRI) in children with diverse etiologies of pulmonary arterial hypertension (PAH). Calculation of pulmonary flow ([Formula: see text]) using the Fick principle in most catheter laboratories relies on an estimate of oxygen consumption which may limit its reliability. Flow hemodynamic indices acquired from thirty patients with PAH who underwent successful same-day PC-MRI and catheterization were evaluated for absolute and percent bias...

OBJECTIVES: This retrospective study aims at demonstrating the success rate, effectiveness, and advantages of alcohol as a scolicidal and sclerosing agent for the percutaneous treatment of liver hydatid cysts. METHODS: A total of 554 liver hydatid cysts obtained from 347 patients admitted between January 2008 and February 2016 were retrospectively investigated. Of these, 435 (78.5%), 91 (16.4%), and 28 (5%) were classified as Gharbi type 1, 2, and 3, respectively...

OBJECTIVE: In the present study, we investigated the effectiveness and reliability of a new method that reveals whether guidewire advanced distal to the lesion is in the lumen in patients with acute (ATO) or chronic coronary total occlusion (CTO). METHODS: Forty-one patients with symptomatic ATO and 22 patients with CTO who were admitted into our catheterization laboratory between January 2016 and March 2017 were included. In patients in whom antegrade filling could not be demonstrated after passing 0...

BACKGROUND: The ideal anaesthetic technique for management of paediatric patients scheduled to undergo cardiac catheterisation is still not standardised. AIM: To compare the effects of ketamine-propofol and ketamine-dexmedetomidine combinations on hemodynamic parameters and recovery time in paediatric patients undergoing minor procedures and cardiac catheterisation under sedation for various congenital heart diseases. MATERIAL AND METHODS: 60 children of either sex undergoing cardiac catheterisation were randomly assigned into two groups Dexmedetomidine-ketamine group (DK) and Propofol-ketamine (PK) of 30 patients each...

BACKGROUND: Pressure and waveform at the catheter tip are continuously monitored during catheterization of pulmonary artery to ensure accurate catheter placement. We present a case in which pulmonary venous blood was unexpectedly collected from the pulmonary artery catheter despite pulmonary artery pressure and waveform detection at the catheter tip, and describe the measures taken to correct the catheter placement.
