1/48. Central venous catheter-associated thrombosis in severe haemophilia.Significant subclavian vein thromboses associated with indwelling fully implanted (port-a-cath) devices are described in two boys with severe haemophilia A and factor viii inhibitors. Investigations were prompted by prominent chest wall veins in one case, whereas the thrombosis was a chance finding in the other case during investigation of mechanical dislocation of the catheter tubing. Extensive collateral venous circulations were demonstrated by venography in both instances indicating that the thrombus had been present for some time. Possible contributing factors to the thromboses included desensitization therapy (both patients), high-dose FEIBA (in one patient) and use of lower doses of heparin for line flush than that recommended by some authors. Neither patient had a familial or non-familial predisposition to thrombosis.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
2/48. Dislodged stent: a simple retrieval technique.We report a technique for retrieval of a dislodged coronary stent using a stiff angioplasty wire positioned beside the initial stent guidewire. This two-wire technique provides a better platform to move and position the snare device without moving the dislodged stent and thus lessens the risk of embolization. If a larger femoral sheath is needed for stent removal, this method facilitates sheath exchange. Cathet. Cardiovasc.

3/48. Late stent malapposition occurring after intracoronary beta-irradiation detected by intravascular ultrasound.We report a case of late stent malapposition occurring 6 months after intracoronary beta-irradiation detected by three-dimensional intravascular ultrasound, in spite of good apposition immediately after the procedure. Volumetric quantification revealed that stent volume remained unchanged, whereas total vessel volume increased by 13% after 6 months within the stent area. The increase of the vessel volume took place mainly in the proximal part of the stent, where the malapposition was located.- - - - - - - - - - ranking = 5.8900647674877keywords = coronary (Clic here for more details about this article) |
4/48. Acute ischemic hepatic failure resulting from intraaortic balloon pump malposition.We describe a rare intraaortic balloon pump (IABP) vascular complication as a result of malpositioning of the IABP. A 61-year-old man with unstable angina underwent emergency coronary artery bypass grafting soon after the insertion of an IABP. Postoperative hemodynamics were stable, but acute hepatic dysfunction occurred on the second postoperative day. Doppler echography revealed the absence of hepatic arterial flow. The IABP was removed, and arterial flow was immediately restored. Thereafter, the hepatic function recovered rapidly. This is a rare case that demonstrates how IABP can cause mechanical abdominal arterial branch obstruction. Evaluations using Doppler echography are useful in detecting such IABP complications.- - - - - - - - - - ranking = 1.1780129534975keywords = coronary (Clic here for more details about this article) |
5/48. Migration of a transjugular intrahepatic portosystemic shunt (TIPS) stent: evaluation by transesophageal echocardiography.Transjugular intrahepatic portosystemic shunting (TIPS) is a procedure for end-stage liver disease that involves angiographically guided placement of an intrahepatic expandable metal stent. Mechanical complications of intrahepatic stent placement have been reported, including stent migration to the central venous circulation. This report describes a patient who had embolization of a stent after a TIPS procedure, with subsequent failed percutaneous attempts at stent removal. Transesophageal echocardiography documented the stent caught in the tricuspid valve and apparatus, with its distal end projecting into the right ventricular cavity.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
6/48. Transfemoral extraction of an intracardiac bullet embolus.Missiles may reach the heart via direct penetration of the thoracic cavity or indirectly by means of the venous circulation. Often the hemodynamic stability of the patient dictates the approach that is used not only to retrieve the projectile but also to repair associated life-threatening injuries. The case of a 40-year-old man with an intracardiac missile after a gunshot wound to the right gluteal area is presented along with the transfemoral technique used to recover an intracardiac projectile. This approach may be used instead of thoracotomy for missile extraction in stable patients.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
7/48. Minimally invasive removal of a dislocated stent from the right atrium after previous CABG.Repeat sternotomy after previous open heart operations constitutes a serious risk factor for cardiac injury, particularly in the presence of a patent internal thoracic artery. We report a case of successful minimally invasive removal of a dislocated subclavian vein stent entangled in the tricuspid valve in a patient 5 years after coronary artery bypass surgery.- - - - - - - - - - ranking = 1.1780129534975keywords = coronary (Clic here for more details about this article) |
8/48. Closure of an iatrogenic aortocoronary arteriovenous fistula: transcatheter balloon embolization following failed coil embolization and salvage of coils that migrated into the coronary venous system.We report a 50-year-old patient with successful percutaneous closure of a large inadvertent surgical aortocoronary arteriovenous fistula (shunt flow: 1.8 L/min). With initial embolization of multiple coils, no lasting occlusion of the large fistula could be achieved. Above that, two coils migrated into the coronary venous system. Following rescue of the migrated coils through a retrograde coronary sinus approach, the fistula was occluded using a detachable balloon. Follow-up angiograms confirmed successful closure of the fistula. In contrast to coil embolization, use of a detachable balloon seems to be the appropriate technique for percutaneous closure of such fistulas.- - - - - - - - - - ranking = 12.958142488473keywords = coronary (Clic here for more details about this article) |
9/48. Embolization of pacing electrode fragment into the superolateral vein in the spinal canal causing root compression.lead extraction may be complicated by lead fracture and embolization of the lead fragments into the pulmonary circulation or other vasculature causing various signs and symptoms. We present a very unusual case demonstrating embolization of a pacemaker electrode fragment into the superolateral vein in the spinal canal causing root compression. The electrode fragment was removed by spinal surgery, and the patient's symptoms gradually resolved.- - - - - - - - - - ranking = 1keywords = circulation (Clic here for more details about this article) |
10/48. Late aortic dislocation of a stent following stent angioplasty for ostial renal artery stenosis.A patient with left RAS was treated by stent angioplasty followed by a multivessel percutaneous coronary intervention. Six months later, an aortic dislocation of the stent was diagnosed. The fully expanded stent was caught with a balloon catheter and fixed in the left external iliac artery. Stent migration after initially successful stent angioplasty for RAS is possible. Fully expanded, dislocated balloon-expandable stents can be secured by implanting them into the iliac artery.- - - - - - - - - - ranking = 1.1780129534975keywords = coronary (Clic here for more details about this article) |
