A 42-year-old woman with a history of breast cancer and hepatic metastatic disease underwent insertion of an implantable venous access catheter into the right subclavian vein (Seldinger technique). After eight months of treatment it was decided to remove the catheter due to reported possible thrombosis and obstruction. The patient was totally asymptomatic. A preoperative chest X-ray was consist...

BACKGROUND Protective lung ventilation is recommended in patients with acute respiratory distress syndrome (ARDS) to minimize additional injuries to the lung. However, hypercapnic acidosis resulting from ventilation at lower tidal volume enhances pulmonary hypertension and might induce right ventricular (RV) failure. We investigated if extracorporeal veno-venous CO2 removal therapy could have b...

BACKGROUND Patients in neurological critical care units often have lengthy stays that require extended vascular access and invasive hemodynamic monitoring. The traditional approach for these patients has relied heavily on central venous and pulmonary artery catheters. The aim of this study was to evaluate peripherally inserted central catheters as an alternative to central venous catheters in n...

BACKGROUND The clinical and hemodynamic assessment at the bedside and the use of pulmonary artery catheter for the estimation of hemodynamic data have been used in decompensated heart failure. However, there are no data on the use of continuous noninvasive hemodynamic monitoring. OBJECTIVE To compare the data obtained through noninvasive hemodynamic monitoring with invasive ones in patients w...

Relationships between artefacts in recorded intracardiac pulses and the dynamic response and susceptibility of catheter-manometer systems to artefacts caused by motion of the catheter were investigated. Sine-wave motions of the catheter, resembling motion frequently seen when the catheter is in the pulmonary artery, produce sine-wave pressure variations with peak-to-peak amplitudes of 10 mm. Hg...

unilateral pulmonary artery agenesis (upaa) is a rare congenital anomaly during the 4 th  week of gestational age. it is defined as an absence of pulmonary parenchyma and its supporting artery. a 9-year-old girl was admitted to our hospital because of chronic cough. chest examination showed a decrement in lung sound of right hemi-thorax with expiratory wheeze. chest radiography (cxr) revealed a...

STATEMENT OF FINDINGS: This case report describes removal of a knotted, subclavian, pulmonary artery catheter using a tracheostomy dilator. With this simple method an invasive procedure might be averted.

background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

Sir, Swan-Ganz catheterization, also known as the balloon tipped pulmonary artery catheterization, is widely used as a diagnostic and hemodynamic tool to monitor patients in the intensive care unit [1]. Knot formation is one of the rare complications with the incidence of 0.2−2.5%, which in general resulting in entrapping the catheter in the superior vena cava [2]. Surgical intervention is nece...
