Direct Aspiration Catheter Fracture and Retrieval during Neurothrombectomy.

ABSTRACT: Background:Application of direct aspiration catheters has revolutionized acute stroke care and has led to significant improvement in clinical outcome with a good safety profile. Catheter fracture and retention is a rare but potentially devastating complication. Case Description:Here we present two cases of acute stroke complicated by aspiration catheter fracture and retention. Successful catheter retrieval and revascularization was achieved in both cases. The stenosis or tortuosity of vascular anatomy appears to be the probable contributor to catheter breakage by anchoring the catheter with resultant fracture at the constraint point from catheter withdrawal tensile stress. Conclusion:This report describes application of snare devices in retrieving a broken catheter during thrombectomy in the anterior and posterior circulation, and therefore presents a technique that can be safely utilized to address catheter breakage complicating thrombectomy in different vascular anatomic locations.

Catheter Aspiration after Every Stage during Primary Percutaneous Angioplasty; ADMIT Trial.

Project description:We assess the epicardial and microcirculation flow characteristics, and clinical outcome by using catheter aspiration after each stage of primary percutaneous coronary intervention (PPCI). Conflicting data are reported regarding early and late benefit of using aspiration catheter in the initial phase PPCI. A total of 100 patients with ST-segment elevation acute myocardial infarction (STEMI) were included: 51 underwent PPCI without using an aspiration device (SA group) and 49 underwent PPCI by activating an aspiration catheter after each stage of procedure; wiring, ballooning and stenting, respectively (MA group). Thrombolysis in myocardial infarction (TIMI) flow grade, TIMI frame counts and myocardial blush grade (MBG) were evaluated in each group during every stage of procedure. Major adverse cardiac events were evaluated in the index hospitalization and during 30 and 180 days of follow-up. A TIMI flow grade 2-3 was more prevalent in the MA group compared with the SA group only after wiring: 65.9 versus 39.1% (p = 0.01), but TIMI frame counts were lower in the MA versus SA group throughout all procedural steps. MBG 2-3 was statistically higher in the MA group compared with the SA group mainly after wiring. After stenting there were no significant changes in both epicardial and microcirculation flow parameters. There were no significant differences between the groups in early and late clinical outcomes. Improved flow parameters were noticed in the MA group only by activating the aspiration device after wiring. This early advantage disappeared after stenting. The initial better flow characteristic in the MA group was not translated into a better early or late clinical outcome.

Direct-access retrieval during sentence comprehension: Evidence from Sluicing.

Project description:Language comprehension requires recovering meaning from linguistic form, even when the mapping between the two is indirect. A canonical example is ellipsis, the omission of information that is subsequently understood without being overtly pronounced. Comprehension of ellipsis requires retrieval of an antecedent from memory, without prior prediction, a property which enables the study of retrieval in situ (Martin & McElree, 2008, 2009). Sluicing, or inflectional phrase ellipsis, in the presence of a conjunction, presents a test case where a competing antecedent position is syntactically licensed, in contrast with most cases of nonadjacent dependency, including verb phrase ellipsis. We present speed-accuracy tradeoff and eye-movement data inconsistent with the hypothesis that retrieval is accomplished via a syntactically guided search, a particular variant of search not examined in past research. The observed timecourse profiles are consistent with the hypothesis that antecedents are retrieved via a cue-dependent direct-access mechanism susceptible to general memory variables.

Tibial tray fracture in a modern prosthesis with retrieval analysis.

Project description:Fracture of the tibial tray is a rarely observed complication of total knee arthroplasty (TKA), predominately in implants placed greater than a decade ago. This case highlights a case of baseplate fracture in a contemporary prosthesis. The patient presented 1 year after TKA with medial knee pain consistent with pes bursitis. The implant-cement-bone construct was intact and she was managed with corticosteroids. She had persistent pain, acutely developed new varus deformity, and presented with a tibial tray fracture. Retrieval analysis suggested fatigue fracture as the likely mechanism. At time of revision, necrotic bone was found at the medial plateau, which likely caused cantilever bending relative to the well-supported portion of the tray and resultant failure. The patient continues to do well 5 years after revision TKA.

Aspiration technique for percutaneous endovascular retrieval of contraceptive device embolized to the pulmonary vasculature.

Project description:Contraceptive implant migration into the pulmonary circulation is an uncommon, but potentially serious complication. We describe an "aspiration" technique for percutaneous retrieval of a contraceptive implant from a subsegmental pulmonary artery, using a Penumbra Neuron MAX 088 guiding catheter and a Merit Medical VacLok Vacuum Pressure Syringe, as an alternative to the previously described snare technique. Our patient had an uneventful recovery and was discharged home on the same day.

An Intravascular Magnetic Catheter Enables the Retrieval of Nanoagents from the Bloodstream.

Project description:The clinical adoption of nanoscale agents for targeted therapy is still hampered by the quest for a balance between therapy efficacy and side effects on healthy tissues, due to nanoparticle biodistribution and undesired drug accumulation issues. Here, an intravascular catheter able to efficiently retrieve from the bloodstream magnetic nanocarriers not contributing to therapy, thus minimizing their uncontrollable dispersion and consequently attenuating possible side effects, is proposed. The device consists of a miniature module, based on 27 permanent magnets arranged in two coaxial series, integrated into a clinically used 12 French catheter. This device can capture ?94% and 78% of the unused agents when using as carriers 500 and 250 nm nominal diameter superparamagnetic iron oxide nanoparticles, respectively. This approach paves the way to the exploitation of new "high-risk/high-gain" drug formulations and supports the development of novel therapeutic strategies based on magnetic hyperthermia or magnetic microrobots.

Successful multi-step catheter intervention for thrombotic inferior vena cava filter retrieval.

Project description:A 45-year-old man, who was implanted with an inferior vena cava (IVC) filter in his infrarenal IVC, had a complication of deep vein thrombosis (DVT) propagation from the IVC, beyond the IVC filter, to the right calf and left external iliac veins. The entire IVC filter was covered with a massive thrombus. We first decided to retrieve the IVC filter itself, which was suspected of causing metallic allergy. The thrombotic IVC filter was successfully retrieved using multi-step catheter intervention. To our knowledge, this is the first case report to describe successful multi-step catheter intervention for retrieval of an IVC filter covered with a massive thrombus. <Learning objectives: Inferior vena cava (IVC) filter thrombosis is one of the most serious IVC filter complications. It is difficult to retrieve the IVC filter covered with a massive thrombus. Multi-step catheter intervention technique may be useful to retrieve an IVC filter with thrombotic occlusion.>.

Pinch-off syndrome from a chemoport catheter successfully managed with endovascular retrieval.

Project description:Introduction and importanceA totally implantable venous access device (TIVAD), also referred to as 'chemoport', is frequently used for oncology patients. Chemoport insertion via the subclavian vein access may compress the catheter between the first rib and the clavicle, resulting in pinch-off syndrome (POS). The sequela includes catheter transection and subsequent embolization. It is a rare complication with incidence reported to be 1.1-5.0% and can lead to a devastating outcomes.Case presentation50-year-old male had his chemoport inserted for adjuvant chemotherapy 3 years ago. During the removal, remaining half of the distal catheter was not found. There was no difficulties during the removal. Chest xray revealed that the fractured catheter had embolized to the right ventricle. Further history taking, he did experienced occasional palpitation and chest discomfort for the past six months. Electrocardiogram and cardiac enzymes were normal. Urgent removal of the fractured catheter via the percutaneous endovascular approach, under fluoroscopic guidance by an experience interventional radiologist was done. The procedure was successful without any complication. Patient made an uneventful recovery. He was discharged the following day, and was well during his 3rd month follow up.ConclusionEarly detection and preventive measures can be done to prevent pinch-off syndrome. Unrecognized POS can result in fatal complications such as cardiac arrhythmia and septic embolization. Retrieval via the percutaneous endovascular approach provide excellent outcome in the case of embolized fractured catheter.

The retrieval of the diagnostic catheter which broke and embolised twice.

Project description:We are presenting a nightmare case of successful retrieval of the broken distal tip of a multipurpose catheter which embolised into the left pulmonary artery (LPA) during atrial septal defect device closure. During the course of snaring it initially slipped once in the LPA and subsequently while snaring it into the delivery sheath it slipped again in the inferior vena cava and yet again embolised into the LPA!! Subsequent attempt was successful but the distal fragment itself broke into two parts while being pulled inside the delivery sheath. Luckily the fragments did not embolise again as they were stuck at the tip of the sheath. The distal fragments were pulled out en masse along with the delivery sheath maintaining negative pressure at the side port of the delivery sheath using a 20 mL syringe. The final outcome was successful and the patient was unharmed by this potentially grave complication.
