Rescue balloon-assisted remodeling technique for protrusion of coil loop: A case report.

ABSTRACT:

Rationale

Among the possible complications during endovascular embolization of intracranial aneurysms, coil protrusion into the parent artery is associated with parent artery occlusion or thromboembolic of the distal arteries. There is no clearly established management strategy for coil protrusion. This report demonstrates our experience with balloon-assisted remodeling to reposition a protruded coil loop.

Patient concerns

A 53-year-old man was admitted to our hospital with severe bursting headache, nausea, and vomiting. Computed tomography showed subarachnoid hemorrhage and digital subtraction angiography revealed an anterior communicating artery aneurysm. We decided to obliterate the aneurysm with endovascular embolization using detachable coils.

Diagnosis

A small loop protruded into the parent artery during the removal of the microcatheter.

Interventions

We performed successful repositioning of the protruded coil loop using balloon inflation.

Conclusion

The rescue balloon-assisted remodeling technique was useful in the management of protrusion of a small coil loop into the parent artery during endovascular coil embolization of an intracranial aneurysm. The procedure was associated with minimal complications.

Combined Balloon-, Plug- and Coil-assisted Retrograde Transvenous Obliteration of Multiple Portosystemic Shunts to Treat Recurrent Hepatic Encephalopathy: A Case Report.

Project description:Balloon- or plug-assisted retrograde transvenous obliteration of portosystemic shunts is an effective endovascular technique for the treatment of type B bypass hepatic encephalopathy. We describe a patient who underwent balloon- and plug-assisted obliteration for a lienorenal and lienogonadal shunt, respectively. He returned with symptoms of recurrent hepatic encephalopathy two years later due to reformation of new lienorenal and lienogonadal shunts. Repeat obliteration of these new shunts was now performed using balloon and coil assistance. We describe the treatment for multiple portosystemic shunts with combined usage of vascular plug, balloon and coils depending on anatomical and technically factors. Our case also highlights that after shunt obliteration increased portal pressure may form new portosystemic collateral pathways which leads to clinical failure and may require repeat treatment.

Implementation of the kissing balloon technique using a perfusion balloon in acute myocardial infarction: a case report.

Project description:BackgroundProlonged antiplatelet-agent administration associated with stenting for acute myocardial infarction is not ideal in young patients. We successfully performed a perfusion balloon-based kissing balloon technique in the left anterior descending artery ostium in a young patient with acute myocardial infarction.Case summaryA 34-year-old female presenting with recurrent chest pain was diagnosed with ST-segment elevation acute myocardial infarction. Emergency coronary angiography revealed 90% stenosis of the left anterior descending artery ostium. Considering her age, lesion dilation using a perfusion balloon was preferred. This inadvertently impinged the left circumflex artery, causing chest pain and ischaemia-related hypotension with only a 10 s perfusion dilation balloon. We transitioned to an alternative 7 Fr guiding catheter and performed the kissing balloon technique using a perfusion balloon. This allowed prolonged inflation for 120 s, without complications. Optical coherence tomography of the lesion revealed layered plaques. Based on the patient's age and medical history, coronary spasm may be the aetiological factor underlying acute ST-segment elevation myocardial infarction. Coronary angiography 3 months post-discharge revealed no restenosis.DiscussionRegarding acute myocardial infarction, prolonged inflation with a perfusion balloon had higher frequency of non-stent-related interventions than that of semi-compliant or non-compliant balloons. In this case, the perfusion balloon resulted in chest pain and hypotension. Perfusion balloon-based kissing balloon technique was useful in this setting. Optical coherence tomography revealing the responsible lesions can help determine the cause of acute myocardial infarction in young patients; in our case, a layered plaque was observed. Layered plaques are associated with coronary spasm; therefore, initiating treatment of coronary spasm was considered herein.

A case report of balloon-assisted tracking to overcome coronary sinus competent valve: a novel technique in left ventricular lead implantation.

Project description:BackgroundCompetent lateral and posterolateral valves showed proximal tortuosity that might hinder left ventricular (LV) lead implantation in cardiac resynchronization therapy (CRT).Case summaryA 57-year-old woman was diagnosed as non-ischaemic cardiomyopathy, no other comorbidities, complaining of dyspnoea [New York Heart Association (NYHA) class III], and on optimal medical therapy. Electrocardiogram showed left bundle branch block with QRS duration 150 ms. The patient was candidate for CRT. However, during LV lead implantation, a competent posterolateral vein valve and proximal tortuosity hindered LV lead implantation that was overcome by balloon-assisted tracking technique. At 9 months of follow-up, the patient had NYHA class II, ejection fraction improved to 38%, and all implanted leads were still in place.DiscussionBalloon-assisted tracking technique can be used to cross coronary sinus and smaller veins with competent valves and coronary veins tortuosity.

Corsair rotational bougie technique for facilitating balloon passage through a total occlusion lesion: a case report of balloon pulmonary angioplasty.

Project description:A 77-year-old man presented with dyspnoea and was diagnosed with chronic thromboembolic pulmonary hypertension. Balloon pulmonary angioplasty was attempted; however, the balloons could not be advanced to the total occlusion lesion in the right A3 segment. The obstruction was overcome using a microcatheter Corsair (AsahiKASEI). This technique may be useful in managing a total occlusion lesion.

Video-Assisted Intubating Stylet Technique for Difficult Intubation: A Case Series Report.

Project description:Induction of anesthesia can be challenging for patients with difficult airways and head or neck tumors. Factors that could complicate airway management include poor dentition, limited mouth opening, restricted neck motility, narrowing of oral airway space, restricted laryngeal and pharyngeal space, and obstruction of glottic regions from the tumor. Current difficult airway management guidelines include awake tracheal intubation, anesthetized tracheal intubation, or combined awake and anesthetized intubation. Video laryngoscopy is often chosen over direct laryngoscopy in patients with difficult airways because of an improved laryngeal view, higher frequency of successful intubations, higher frequency of first-attempt intubation, and fewer intubation attempts. In this case series report, we describe the video-assisted intubating stylet technique in five patients with difficult airways. We believe that the intubating stylet is a feasible and safe airway technique for anesthetized tracheal intubation in patients with an anticipated difficult airway.

Parent Vessel Occlusion via the Balloon-Assisted, Dual Microcatheter Technique.

Project description:Endovascular parent vessel sacrifice is an established technique used to treat vascular pathology and tumor infiltration of blood vessels. In high-flow vessels, such as the carotid artery or vertebral artery, distal coil migration and embolization are concerns. A method to mitigate this risk would improve the safety profile of the procedure. Five patients undergoing parent vessel sacrifice were retrospectively identified (from June 2018 to May 2019) for the purpose of illustrating this high-flow parent vessel occlusion technique. The technique utilizes a proximal dual-lumen balloon microcatheter inflated for blood flow arrest. The balloon-assisted, dual microcatheter technique is useful for occlusion of high-flow parent arteries. Because it utilizes both flow arrest and a tethered coil backstop, precise occlusion of a vessel can be achieved.

Foetoscopy-assisted balloon valvuloplasty in a human foetus with disadvantageous intrauterine position: a case report.

Project description:BackgroundSome foetuses scheduled for balloon valvuloplasty present with unfavourable lies that render a successful procedure unlikely or impossible. In these situations, foetal posturing previously has been achieved by maternal laparotomy. As a less invasive means, we demonstrate the feasibility of a minimally invasive foetoscopic approach.Case summaryPercutaneous ultrasound-guided foetal balloon valvuloplasty for severe aortic valve stenosis was attempted in a human foetus at 29 + 4 weeks of gestation under general maternofoetal anaesthesia. Unfortunately, prior to the procedure, the foetus had been observed on several occasions remaining in a dorsoanterior cephalic position. Therefore, the left ventricle could not be accessed by the conventional percutaneous ultrasound-guided approach. In order to achieve the desired foetal lie, foetoscopic assistance was employed: using a standardized foetoscopic setup, a foetoscope and two graspers, the foetus was rotated in dorsoposterior position. After this manoeuver, successful balloon valvuloplasty was achieved. Mother and foetus tolerated the procedure well and complications were not observed.DiscussionFoetoscopy-assisted foetal posturing offers itself as an alternative to maternal laparotomy in foetuses presenting with a persisting disadvantageous position at the time of balloon valvuloplasty. Due to the increased risks of preterm rupture of membranes and earlier delivery posed by the foetoscopic approach, this technique may preferably be used in more mature foetuses when foetal posturing cannot be achieved by other means.

Balloon-hooking technique for stabilizing a guiding catheter in tortuous supra-aortic vessel: A case report.

Project description:Objective: When performing endovascular interventions for supra-aortic vessels, the tortuous vascular anatomy observed in patients with atherosclerotic lesions often limits the ability to maintain a stable guiding catheter position. Here, we report a case of right vertebral artery (VA) stenosis treated with transfemoral stenting and discuss the utility of balloon-hooking technique using partially inflated balloon for stabilizing the balloon guiding catheter (BCG) in the supra-aortic vessel. Case presentation: A 74-year-old man who underwent right carotid artery stenting, coronary artery bypass grafting, and bilateral iliac artery stenting was admitted to our emergency department because of dizziness related to head movement. Computed tomography angiography revealed right VA origin stenosis and left subclavian artery (SA) occlusion. The patient underwent stenting of the right VA. After several unsuccessful cannulation attempts into the right VA through transradial access, transfemoral access was obtained through the left iliac stent. A 9-Fr BGC was navigated into the right SA. The balloon was partially inflated just distal to the first curve of the right SA and used as hook by pulling back until the proximal edge of the balloon was pushed distally by the lesser curvature of the SA, resulting in stabilization of the BGC and successful angioplasty and stent deployment at the VA stenosis. The patient's symptoms resolved completely, without any neurological deficits. Conclusions: Balloon-hooking technique using a partially inflated BGC is feasible for stabilizing the guiding catheter in tortuous supra-aortic vessel.

Rescue aortic balloon valvuloplasty during procedural cardiac arrest while treating critical left main stem stenosis: a case report.

Project description:Background:Best timing for coronary revascularization in patients with severe aortic stenosis (AS) who was a candidate for transcatheter aortic valve implantation (TAVI) is still matter of debate. Case summary:We here report the case of an 87-year-old man with severe AS presenting with non-ST-segment elevation myocardial infarction. Coronary angiography revealed a highly complex and calcific left main stem (LMS) lesion. Rotablation-assisted percutaneous coronary intervention (PCI) was attempted but was complicated by post-stenting rapidly evolving haemodynamic impairment. A rescue 'pacing-free' balloon aortic valvuloplasty (BAV) was performed to rescue the patients, allowing prompt restoration of cardiac output and coronary perfusion. Discussion:According to guidelines and preliminary evidence, decision should be performed case by case and based on the degree of severity and complexity of either AS or coronary disease. The strategy of treating coronary lesions first may limit the risk of potential ischaemic complications during TAVI. However, the downside of it is the risk of hemodynamic crash with potential catastrophic evolution in case of PCI complications in presence of severe AS. A 'bailout BAV' can be considered as a salvage-strategy in case of complex and complicated LMS-PCI in the context of severe AS and advanced status of haemodynamic impairment. This approach must be seen as very last resort, while appropriate pre-procedural planning is still highly recommended in order to prevent potentially fatal procedural complications in this fragile clinical setting.
