PURPOSE To present a technique for transfemoral implantation of parallel grafts into the renal arteries in patients with anatomy or morphology that blocks standard antegrade chimney graft delivery. TECHNIQUE In a totally percutaneous approach, a 5-F pigtail angiographic catheter is passed into the aorta above the renal arteries via a 0.035-inch hydrophilic guidewire, followed by an 8-F sheath...
In contrast with the direct brachial technique (see Chapter 5), the percutaneous approach to left and right heart catheterization achieves vascular access by needle puncture , and thus obviates surgical isolation of the vessel during either the insertion or the subsequent withdrawal of the cardiac catheter. Once the needle has been positioned within the vessel lumen, a flexible guidewire is adv...
Introduction In the rapidly developing field of interventional MR, there has been growing concern about RF-induced heating in metallic devices[3]. In the work reported here, we concentrate on the RF heating of a widely used intravascular guidewire, the Terumo guidewire (Tokyo, Japan), having a nitinol (Nickel-Titanium) core. Since nitinol is not ferromagnetic, the Terumo meets an important cond...
Contralateral injection has been described as a useful tool in the treatment of chronic total occlusions (CTOs) to evaluate the distal segments of the occluded artery [1, 2]. This case shows that contralateral injections are feasible through just one puncture using a 6 Fr sheath, a long guidewire of 0.014” and a 5 Fr diagnosis catheter in parallel. We present a 64-year-old man with severe perip...
The number of complications between guidewires and inferior vena cava filters is unknown and most likely underreported. Since 1993, at least 17 cases of central venous catheter guidewires entangled in inferior vena cava filters have been reported. The placement of both devices in the intensive care setting has increased the number of incidents in which a guidewire from a central venous catheter...
There has been a growing trend toward percutaneous coronary angioplasty for complex coronary artery lesions. Stent or guidewire break off or trapping within the coronary artery lumen is a rare complication, but it may have fatal consequences. In such cases, the entrapped device may be removed by either percutaneous route or surgical exploration. Here, we report a patient with guidewire entrapme...
Guidewire manipulation to negotiate branches originating at an acute angle from the parent artery is a frequently encountered challenge by the interventional cardiologist in clinical practice. To date, several methods have been developed, but none of them has a definitive success rate. Here, we report a technique for negotiating extremely angulated vascular bifurcations, with which we have achi...
Objective: To determine whether it is the direction of the needle bevel, J-tip guidewire, or both that influences the direction of the guidewire in subclavian central line placement. Methods: A total of 1,200 trials were performed using a plastic tubular model simulating the subclavian, IJV, and SCV junction. The trials were divided into six groups: needle bevel pointed upwards with J-tip direc...
The present article presents the case of a 70-year-old male, with a history of acute anterolateral myocardiac infarction (AMI) in 1986 and inferior AMI in 1992. Coronary arteriography was performed in 1995, which showed occlusion of the distal RCA and stenosis in 90% of the proximal LAD, with an ejection fraction (EF) of 29%. Balloon angioplasty was performed in the proximal LAD. The patient wa...
