1/32. 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 = 1keywords = vessel (Clic here for more details about this article) |
2/32. Successful surgical removal of an intrapulmonary aberrant needle under fluoroscopic guidance: report of a case.We describe herein the successful surgical removal of an intrapulmonary aberrant needle. An asymptomatic 47-year-old woman underwent a routine chest X-ray which revealed a needle located in the right S8 area. We first tried to extract the needle; however, fluoroscopic examination confirmed that it had broken into two pieces and therefore, partial resection of the right S8 was performed. To avoid rethoracotomy, the operation was done under fluoroscopic guidance. An intrathoracic aberrant needle should always be removed surgically as soon as possible, even if the patient is asymptomatic, due to the possibility of its migration into the vessels and the development of lung abscess or pyothorax.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
3/32. 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 = 0.5keywords = vessel (Clic here for more details about this article) |
4/32. Mesh repair of a pelvic bone defect caused by a migrated acetabular cup.Conventional transacetabular removal of the migrated acetabular cup can be hazardous due to intraoperative injury to iliac vessels. We present a case of a migrated acetabular cup, in which we used a combined preperitoneal and acetabular approach for its removal. With a bimanual approach, the procedure was safer and easier and allowed mesh repair of the pelvic bone defect. The preperitoneal mesh repair is a well-known method for inguinofemoral hernias. However, it has not been used before in the repair of an acetabular defect after removal of a migrated cup.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
5/32. Transvascular coil hooking procedure to retrieve an unraveled Guglielmi detachable coil: technical note.OBJECTIVE: A patient with an anterior communicating artery aneurysm was treated by use of endovascular coiling, and a Guglielmi detachable coil (boston Scientific/Target, Fremont, CA) fractured distal to its connection to the delivering catheter. The unraveled coil floated out from the aneurysm to extend into the bifurcation of the left middle cerebral artery. We describe the microsurgical procedure used to retrieve the coil after an endovascular approach failed. methods: The left anterior cerebral artery was punctured just below the aneurysm neck, and a titanium microhook was introduced to anchor the coil and pull it out. Slight traction was exerted before sectioning the coil to avoid protrusion of the stump into the parent vessel. RESULTS: The unraveled coil was removed in totality without permanent morbidity. CONCLUSION: This report describes the case of a rare complication of coil embolization treated with a minimal transarterial coil hooking procedure.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
6/32. 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 = 0.5keywords = vessel (Clic here for more details about this article) |
7/32. Management of neuroform stent dislodgement and misplacement.A self-expanding stent has recently been introduced for the treatment of wide-neck aneurysms. We describe two cases of stent malposition within large aneurysms. In the first case, the stent was dislodged during microcatheterization. This was managed by placement of a second stent through the interstices of the first followed by aneurysm coiling. In the second case, after deployment, the proximal portion of the stent moved into the aneurysm as the exchange guidewire was removed. This patient was treated by vessel sacrifice.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
8/32. Ventricular tachycardia associated with transmyocardial migration of an epicardial pacing wire.A 66-year-old man who had undergone a three-vessel coronary artery bypass grafting (CABG) procedure 3 years previously presented with ventricular tachycardia (VT) and cardiac arrest. echocardiography demonstrated a wire coursing through the right ventricle into the pulmonary artery. The wire was removed with a snare and confirmed to be an epicardial temporary pacing wire placed during the CABG operation. We suspect that the epicardial pacing wire eroded through the right atrium and migrated into the right ventricle, contributing to the VT. Complications due to temporary epicardial pacing wires placed during CABG are discussed.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
9/32. Acute laryngeal paralysis induced by the migration of a totally implantable venous access device's catheter tip.The authors report a case of acute vagus nerve paralysis that appeared during a course of chemotherapy. The drugs had been administered through a totally implantable venous access device (TIVAD), whose catheter tip had migrated into the right internal jugular vein (IJV) and was surrounded by a complete venous thrombosis. The supposed aetiology of this paralysis was a leakage of the cytotoxic drug (5-fluorouracil) from the vessel wall into the surrounding carotid space, because of the stagnation of the chemotherapeutic agent above the thrombosis. Four months after cessation of chemotherapy, the laryngeal paralysis was still evident.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
10/32. Late vascular injury following intertrochanteric fracture reduction with sliding hip screw.A case involving late injuries to pelvic vessels caused by a sliding hip screw penetrating through the acetabulum has not been previously reported. We present the case of an 88-year-old man who presented with a retroperitoneal and extraperitoneal hematoma 4 months after open reduction and internal fixation of an intertrochanteric hip fracture. Surgical exploration showed a laceration of the left external iliac artery, which was repaired. However, the sliding hip screw was left in place. The patient's condition deteriorated, and he expired 2 days later. Postmortem examination revealed a laceration of the left internal iliac vein. Our calculations show that the compression screw utilized in the fixation may not have been properly engaged into the sliding screw.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
