The Onyx system has been well established in recent years as a very important material in the treatment of arteriovenous malformations (AVMs). When using the Onyx, it is essential to wait for the creation of a plug around the tip of the catheter, which enables the effective forward penetration of Onyx. Recent reports have shown that the introduction of a dimethyl sulfoxide compatible dual-lumen...

Use of the Avalon Elite bicaval dual lumen catheter (Maquet Cardiopulmonary AG, Rastatt, Germany) can be effective in patients requiring venovenous extracorporeal membrane oxygenation (VV-ECMO) for adult respiratory distress syndrome (ARDS). Proper placement of the cannula is important in providing adequate therapy and avoiding life-threatening complications.  We report a case of successful can...

BACKGROUND The indwelling venous catheter such as Dual-Cath or Twin-Cath is widely used in haemodialysis. Although the manufacturer recommends filling the catheter lumen with heparin after the dialysis session to prevent clotting, little is known about the systemic effects of such a procedure. METHODS Twenty haemodialysis patients with Dual-Cath were studied. Dialysis anticoagulation was achi...

PURPOSE To report our experience using a commercially available catheter-based system equipped with an intravascular ultrasound (IVUS) transducer to achieve controlled true lumen re-entry in patients undergoing subintimal angioplasty for chronic total occlusions (CTO) or aortic dissections. METHODS During an 8-month period, 10 patients (6 men; mean age 73.4 years) with lower extremity (LE) is...

The objective of the study was to evaluate the performance of an amperometric enzyme based lactate sensor and to investigate the possibility of replacing a double lumen catheter based blood withdrawal system with a heparin coated single lumen system. The inner lumen of a double lumen catheter which was placed in a peripheral vein was perfused with heparin solution. The outer lumen was used to c...

The concept of counterpulsation was introduced over four decades ago by Clauss et al. (1) and adapted to intra-aortic balloon pumping (IABP) by Moulopaulus et al. (2) in 1962, and it remains the most common mode of cardiac assist. Intra-aortic balloon counterpulsation (IABCP) was first introduced into clinical practice by Kantrowitz et al. (3) in 1968 for the treatment of cardiogenic shock. Ini...

BACKGROUND To determine the suitability of different superimposed high-frequency jet ventilation (SHFJV) application methods during tracheal bleeding. OBJECTIVE To determine the effect of SHFJV on the aspiration of blood during tracheal bleeding. METHODS A test lung was ventilated using SHFJV via a rigid endoscope, a jet laryngoscope and a 4-lumen jet catheter. Packed red blood cells (PRBCs...
