Managing peripherally inserted central catheter-related venous thrombosis: How I do it.

Imaging-guided insertion of central venous catheters, either in the form of a peripherally inserted central catheter (PICC) or through a subclavian or a jugular approach, is becoming the preferred method of acquiring long-term venous access for a variety of therapeutic purposes. The most significant complication from central venous catheters is thrombosis of the catheterized vein. Venous thrombosis related to the insertion of PICC lines is conventionally treated with line removal followed by anticoagulation. Direct thrombolysis with urokinase, using the lumen of the PICC line to facilitate the insertion of the infusion catheter is a simple, safe and effective treatment option. In this article, we describe our experience with this procedure and the technique used.

Use of intra-arterial multi-detector row CT angiography for the evaluation of an ischaemic limb in a patient with renal impairment.

The vastly improved scanning speed and z-axis resolution afforded by multi-detector technology has allowed CT to refine its traditional roles and to explore many new applications in imaging. We present a case report of a patient with renal failure and an ischaemic leg, which illustrates a useful new CT vascular imaging application. By carrying out 16-channel multi-detector row CT angiography through a sheath introduced into the common femoral artery, we obtained a high-quality angiographic image of the affected leg, using only 30 mL of iodinated contrast material. The examination definitively showed the number, distribution and patency of the tibial run-off arteries, with significant influence on the patient's subsequent clinical management. This simple and relatively minimally invasive technique is useful in peripheral vascular imaging, when conventional CT angiography using a large volume of i.v. contrast and MR angiography are unsuitable or unavailable.

Non-invasive multislice computed tomography coronary angiography for imaging coronary arteries, stents and bypass grafts.

Abstract Multislice computed tomography (MSCT) is evolving rapidly and available data suggest that MSCT coronary angiography may be a reliable and accurate non-invasive imaging modality of coronary arteries. Current generations of MSCT scanners have high sensitivity and specificity for diagnosing native coronary artery disease and coronary bypass graft occlusion. The performance of MSCT in the evaluation of stent patency is still being assessed. In comparison with conventional selective coronary angiography (SCA), MSCT is non-invasive, cheaper and it has the advantages of imaging plaque compositions as well as assessment of luminal patency. Nevertheless, the role of MSCT in the management of coronary artery disease is yet to be fully defined.
