IN 1960 we reported a method of measuring blood flow in individual vessels based on the principle of local thermodilution.1 The present communication presents application of the same principle to measurement of blood flow in the femoral artery in man at rest and during exercise. Methods An upstream catheter was used, modified to allow for percutaneous insertion by the Seldinger technic (fig. 1)...

ABSTRACT BACKGROUND Despite recent advances in antibiotic treatment, pyogenic ventricular brain infections are still associated with adverse clinical outcome 80% of affected patients and mortality rates approaching 60%. The limitation penetration into the cerebrospinal fluid (CSF) challenges treatment. Intrathecal treatment remains an option for adjunctive therapy to intravenous (iv) antibiotic...

OBJECTIVES To validate intravascular ultrasound (IVUS) measurements for differentiating functionally significant from nonsignificant coronary stenosis. BACKGROUND To date, there are no validated criteria for the definition of a flow-limiting coronary artery stenosis by IVUS. METHODS Preinterventional IVUS imaging (30-MHz imaging catheter) of 70 de novo coronary lesions was performed. The le...

A central venous catheter tip located too high into the superior vena cava (SVC) is known to be a strong risk factor for central venous thrombosis and subsequent SVC syndrome. We report herein the usefulness of catheterizing the implanted port catheter lumen as a salvage procedure to circumvent a complete SVC occlusion in a breast cancer patient. Because the standard central vein catheterizatio...

Introduction Many intravenous (IV) drugs are required for complex and polypathologic critically ill ICU patients management. ICU nurses are daily confronted with drugs preparation and administration (solvent type and volume, infusion rate). They also have to deal with drugs physiochemical incompatibilities (PCI), especially as various IV medications are delivered via a single catheter lumen. PC...

We present a 77-year-old female with heavily calcified chronic total occlusions (CTO) in a superficial femoral artery treated by endovascular therapy using a Wingman crossing catheter, which is an over-the-wire catheter with a metallic blade, controlled manually. The blade could probe and track the calcified cap of CTO, wherein any hydrophilic guidewires or looped wires could not penetrate. Mor...

BACKGROUND Pulmonary artery rupture can be a lethal complication of a pulmonary artery catheter (PAC). Different techniques have been used to manage PAC-induced pulmonary artery rupture, including double lumen endotracheal tube (DLT), bronchial blockers, pulmonary artery embolization, thoracotomy with hematoma evacuation, and extracorporeal life support for ventilation (ECLS). Single lumen endo...

INTRODUCTION Ultrasound guidance decreases complications of central venous catheter (CVC) placement, but risks of arterial puncture and inadvertent arterial catheter placement exist. Ultrasound-assisted detection of guidewire position in the internal jugular vein could predict correct catheter position before dilation and catheter placement. METHODS Ultrasound examinations were performed in a...
