OBJECTIVE Intravenous catheters have been indispensable tools of modern medicine. Although intravenous applications can be used for a multitude of purposes, these applications may cause complications, some of which have serious effects. Of these complications, the most commonly observed is phlebitis. This study was conducted to determine the effect of catheter indwell time on phlebitis developm...

pseudoaneurysms rarely occur as a serious complication following incomplete hemostasis of an arterial puncture site. as a result of the increase in diagnostic and therapeutic angiography, the frequency of iatrogenic pseudoaneurysm has increased as well. iatrogenic pseudoaneurysms associated with angiographic catheterization occur most commonly in the common femoral artery. here we report a case...

A 20-year-old female diagnosed as idiopathic pulmonary arterial hypertension at 7 years of age was referred with worsening dyspnea and chest pain. Several imaging studies and right cardiac catheterization showed multiple stenoses in the peripheral pulmonary arteries with severe pulmonary hypertension and multiple systemic arterial stenoses lacking in systemic hypertension. No evidence of inflam...

This is a frail 73-year-old male with symptomatic critical aortic stenosis (AS). He has suffered a significant functional decline with associated shortness of breath and chest discomfort. His past medical history is significant for coronary artery disease with prior bypass grafting, porcelain aorta, chronic kidney disease-stage III, diabetes mellitus, hypertension, hyperlipidemia, and periphera...

diagnosis of cardiac tamponade has been mainly based on clinical features and echocardiography. however, ct may be an initial tool for the evaluation of cardiac tamponade because cutting edge ct is increasingly being installed in the emergency room, and presentation of cardiac tamponade can be nonspecific. importantly, ct has better spatial resolution compared with echocardiography. thus, ident...

mitral regurgitation (mr) is a common valvular lesion in the general population with considerable impact on mortality and morbidity. the mitraclip system (abbot laboratories, abbot park, il, usa) is a novel percutaneous approach for treating mr which involves mechanical edge-to-edge coaptation of the mitral leaflets. we present our initial experience with the mitraclip system in 5 patients. in ...

BACKGROUND Obtaining vascular access is difficult in certain patients. When routine peripheral venous catheterization is not possible, several alternatives may be considered, each with its own strengths and limitations. DISCUSSION We describe a novel technique for establishing vascular access in Emergency Department (ED) patients: the placement of a standard catheter-over-needle device into t...

OBJECTIVE The purpose of this study is to compare the rates of urinary tract infection (UTI) and postoperative urinary retention (POUR) in patients undergoing lower limb arthroplasty after either indwelling urinary catheterization or intermittent urinary catheterization. METHODS We conducted a meta-analysis of relevant randomized controlled trials (RCT) to compare the rates of UTI and POUR in...

A large study conducted at two southeastern US hospitals from October 2007 through October 2008 sought to identify predictive variables for successful intravenous catheter (IV) insertion, a crucial procedure that is potentially difficult and time consuming in young children. The data was collected on a sample of 592 children that received a total of 1,195 attempts to start peripheral IV cathete...

in this survey, made to determine instances of bacteriuria occurring in hospitalized patients who had undergone catheterization, 259 urine specimens were taken from 103 patients admitted to three hospitals in tehran. of the 73 patients who had no urinary tract infection or contamination, 40 (54.8%) developed bacteriuria at the end of catheterization. incidence of bacteriuria in patients under a...
