1/584. 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 = migration (Clic here for more details about this article) |
2/584. 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 = migration (Clic here for more details about this article) |
3/584. Severe migratory granulomatous reactions to silicone gel in 3 patients.In humans implanted with silicone gel breast prostheses, a mild foreign body response results in the formation of a collagenous capsule around the prosthesis. Although many such patients may show evidence of a microscopic granulomatous foreign body reaction upon examination of capsular material at explantation of a prosthesis, it is unusual to have large, palpable granulomas, even in the presence of rupture or leakage. Rare patients have had severe local inflammation and complications resulting from silicone migration to the axilla, arm, or abdominal wall. We describe 3 patients who had deforming granulomas after implant rupture, along with other consequences of silicone gel migrating down the upper extremity. Silicone gel, once it leaves the implant, is not biologically inert and in some persons can elicit profound pathologic responses.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
4/584. Pediatric scalp laceration repair complicated by skin staple migration.skin staples are ideal for pediatric scalp laceration closure because of their rapidity of placement and economy and ease of use. We report two cases of rotatory staple migration necessitating improvised removal techniques. Clinicians should be alert for this complication, which may result from a combination of staple design, local anatomic factors, superficial placement, and prolonged delay prior to removal.- - - - - - - - - - ranking = 5keywords = migration (Clic here for more details about this article) |
5/584. pulmonary embolism caused by acrylic cement: a rare complication of percutaneous vertebroplasty.A pulmonary embolus of acrylic cement was present in a 41-year-old woman with Langerhans' cell vertebral histiocytosis (LCH) after percutaneous vertebroplasty. Chest radiograph and CT confirmed pulmonary infarction and the presence of cement in the pulmonary arteries. She was treated with anticoagulants, and responded favorably. This rare complication occurred because perivertebral venous migration was not recognized during vertebroplasty. Adequate preparation of cement and biplane fluoroscopy are recommended for vertebroplasty.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
6/584. Migration of sterilisation clips: case report and review.A case is reported of a sterilisation clip which was discovered, three years after operation, to have migrated to the subcutaneous tissue. A review of current techniques of female sterilisation is given together with a discussion of other relevant accounts of clip migration. It is shown to be a rare event with no reported serious sequelae. There is no conclusive evidence to suggest that one type of clip is more likely to migrate than another.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
7/584. The intravascular migration of an epidural catheter.The intravascular migration of an endhole epidural catheter in a child is described. We suggest measures to reduce the risk of inadvertent intravenous administration of local anaesthetic and means of reducing the effects of this with particular relevance to paediatric practice.- - - - - - - - - - ranking = 5keywords = migration (Clic here for more details about this article) |
8/584. A case of dislodged atrial screw-in lead with migration to the ventricle 1 year postoperatively.We report a rare case of a 53-year-old woman with a dislodged atrial screw-in lead that migrated to the ventricle 1 year after pacemaker implantation. While such an event is quite unusual, we should be aware of its possibility.- - - - - - - - - - ranking = 4keywords = migration (Clic here for more details about this article) |
9/584. Relapsing pneumonia due to a migrating intrathoracic foreign body in a World war II veteran shot 53 years ago.In the great majority of cases of long-standing intrathoracic foreign bodies, patients are asymptomatic. However, symptoms may occur years later from the migration of the foreign body. We report on a 70-year-old patient who developed relapsing pneumonia due to obstruction of a bronchial branch of the left apical group by a migrating infantry bullet impacting 53 years ago. This was not diagnosed until the second attack of pneumonia in 1998. The bullet remains were removed bronchoscopically and the pneumonia resolved completely without further complications.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
10/584. Migration of three endoclips following laparoscopic cholecystectomy.We present a well-documented case report on migration of the haemostatic clip, along with the two clips that had originally been applied on the cystic duct, into the bile duct forming the nidus of a stone after laparoscopic cholecystectomy--a unique occurrence heretofore unreported. The English language literature on the subject is reviewed. The most likely predisposing factor is improper or erratic application of clips resulting in bile leakage, either subclinical or overt. Secure and correct placement of clips could help to prevent this complication.- - - - - - - - - - ranking = 1keywords = migration (Clic here for more details about this article) |
