1/130. Endovascular repair of a descending thoracic aortic aneurysm: a tip for systemic pressure reduction.A proposed technique for systemic pressure reduction during deployment of a stent graft was studied. A 67-year-old man, who had a descending thoracic aneurysm, was successfully treated with an endovascular procedure. An occluding balloon was introduced into the inferior vena cava (IVC) through the femoral vein. The balloon volume was manipulated with carbon dioxide gas to reduce the venous return, resulting in a transient and well-controlled hypotension. This IVC-occluding technique for systemic pressure reduction may be safe and convenient to minimize distal migration of stent grafts.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
2/130. popliteal artery occlusion as a late complication of liquid acrylate embolization for cerebral vascular malformation.Occlusion of arteriovenous malformations of the brain (BAVMs) by means of an endovascular approach with liquid acrylate glue is an established treatment modality. The specific hazards of this procedure are related to the central nervous system. In the case of unexpectedly rapid polymerization of the cyanoacrylate glue and adhesion of the delivering microcatheter to the BAVM, severing the catheter at the site of vascular access is considered an acceptable and safe management. We present a unique complication related to this technique that has not been described yet. Fragmentation and migration of the microcatheter, originally left in place, had caused popliteal artery occlusion, which required saphenous vein interposition, in a 25-year-old man. Suggestions for avoiding this complication are discussed.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
3/130. 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 = 19.152585911473keywords = thrombosis, vein (Clic here for more details about this article) |
4/130. Combined central retinal artery and central retinal vein occlusion following pars plana vitrectomy.Combined occlusion of the central retinal artery and central retinal vein is an infrequently encountered clinical entity. Although there are reports in the literature of a combined occlusion of the central retinal artery and vein, its occurrence following pars plana vitrectomy has not been described. We report the case of an elderly patient who developed this unusual occurrence following an uneventful pars plana vitrectomy for a posteriorly dislocated IOL.- - - - - - - - - - ranking = 6keywords = vein (Clic here for more details about this article) |
5/130. Aortoduodenal fistula: a late complication of intraluminal exclusion of an infrarenal aortic aneurysm.During recent years, considerable clinical experience has been gained with endoluminal stent-graft procedures. Several studies have shown promising results up to a period of 4.5 years. However, long-term follow-up studies are still limited. Late endoleaks caused by stent-graft migration, disconnection of single components in modular stent-grafts, and limb thrombosis have been observed as long-term complications. We report a case in which a migrated and kinked bifurcated stent-graft caused an aortoduodenal fistula 20 months after stent-graft insertion. To our knowledge, such a complication has not been reported before.- - - - - - - - - - ranking = 2.8587643185788keywords = thrombosis (Clic here for more details about this article) |
6/130. Buckling of the tethering catheter causes migration of a temporary caval filter to the right atrium.AIM: To report problems in the tethering catheter shaft of the Tempofilter, temporary caval filter. MATERIALS AND methods: Two cases are reported where the tethering catheter shaft of the Tempofilter buckled within the jugular vein. RESULTS: Buckling of the tethering shaft caused cephalic migration of the filter into the right atrium. Both filters were uneventfully removed without adverse sequelae. CONCLUSION: These cases demonstrate another mechanism of tethering shaft shortening which results in unexpected migration of the filter. This device is potentially dangerous because of the liability of the tethering cather to buckle at or near the insertion site with cephalic migration of the filter. Improvements in the tethering catheter mechanism need to be made before further patient usage.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
7/130. Management of a rare complication of endovascular treatment of direct carotid cavernous fistula.A 30-year-old woman with direct carotid cavernous fistula underwent endovascular treatment with detachable balloons via a transarterial route. The patient returned with diplopia 1 year after therapy. On cranial MR imaging, one of the balloons was detected in the proximal portion of the superior ophthalmic vein and was deflated percutaneously with a 22-gauge Chiba needle under CT guidance. The patient's symptoms resolved after balloon deflation. This case report presents a unique complication of endovascular treatment of direct carotid cavernous fistula and its management.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
8/130. Intracranial dislocation of a lumbo-peritoneal shunt-catheter: case report and review of the literature.We report on the dislocation of the tip of a lumbo-peritoneal shunting catheter into the cerebral parenchyma 10 months after insertion. The progressive migration towards the deep structures of the brain, once the catheter had left the peritoneal cavity, might have been caused by CSF-flow. Such hypothesis is supported by modern MRI technology visualizing CSF-flow in a spino-cerebral direction.- - - - - - - - - - ranking = 0.040522833126379keywords = deep (Clic here for more details about this article) |
9/130. Migration of a K-wire from the distal radius to the heart.K-wires and Steinmann pins are used to provide internal fixation for fractures or osteotomies. In some instances, removal of the implant is planned and the implant is left long to facilitate its removal. In other instances, implant removal is not planned and the implant is cut off at the level of the bone. Migration of these implants to solid organs or body cavities has been reported. Extravascular migration may occur along tissue planes assisted by muscle motion. Large vessel penetration can occur and has been reported with subsequent migration of the implant to the heart. This case report documents the loosening of a K-wire used in the distal radius to supplement the fixation of a complex intra-articular fracture, migration of the implant along tissue planes, penetration into a peripheral vein, and continued migration of the implant to the heart. There are multiple reports documenting wandering bullets, venous catheter tips, and invasive monitoring devices in the extremities. This is only the second case report that the authors are aware of that confirms migration of an implant from the distal extremity to the heart.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
10/130. Strecker stent migration to the pulmonary artery: long-term result of a "wait-and-see attitude".Accidental dislodgement of an endoprosthesis into the right cavities or the pulmonary artery is a rarely described complication of percutaneous venous stenting. In such cases the migrated stent needs to be promptly extracted by percutaneous techniques in order to avoid any major complication. We report the first case of a delayed Strecker stent migration from the left innominate vein into the right pulmonary artery, successfully managed with anticoagulant therapy and a "wait-and-see" attitude. The advanced stage-disease (metastatic cancer patient) and the large-caliber stent in a disease-free pulmonary artery led us to adopt this unorthodox attitude, as compared with the current clinical practice.- - - - - - - - - - ranking = 1keywords = vein (Clic here for more details about this article) |
