Bard Conquest PTA Balloon dilation Catheter, 6mm x 40mm, 75 cm, Cat. No. CQ7564, UDI: (01) 00801741062902 - Product Usage: use in Percutaneous Transluminal Angioplasty of the femoral, iliac, and renal arteries and for the treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae.
Significant narrowing of the branch pulmonary arteries (PA) may occur following surgical arterioplasty which can lead to disproportionate pulmonary blood flow to the lungs. The conventional procedure of percutaneous transluminal balloon angioplasty of narrowed branch PAs is of limited usefulness in reducing the pressure gradients and importantly, it can have fatal implications like vessel rupture, dissection, aneurysm formation or even death.1 The advent of balloon expandable stents has given better results with lower recurrence rates and complications.

This study aimed to clarify the usefulness of the Ikari-curve left (IL) guiding catheter for balloon pulmonary angioplasty (BPA).The current BPA strategy for chronic thromboembolic pulmonary hypertension is dilation of as many branches as possible to normalize hemodynamics and oxygenation. The shape of the guiding catheter is a major factor in achieving this. However, conventional guiding catheters are difficult to introduce into particular branches. The IL guiding catheter may be suitable; however, its utility remains unclear.We retrospectively analyzed 202 consecutive BPA sessions of 40 patients from November 2016 to Oct...
Authors: Golino M, Nuzzo S, Briguori C Abstract Stentys self-apposing stent was designed to face complex lesions in the precincts of percutaneous coronary interventions. Nitinol platform and disconnectable struts were designed to provide a complete apposition on the vessel wall in challenging lesions such as significant tapering, primary angioplasty in ST segment elevation myocardial infarction and bifurcation. Stentys X-Position S is a sirolimus eluting stent with a novel delivery system aiming to improve positioning. Clinical trials showed good results in terms of procedural success rate, clinical outcome and sho...

CONCLUSIONS: Radiographically detectable caval pseudoaneurysm and extravasation is not uncommon in complex inferior vena cava filter retrieval and, despite being considered a major complication by Society of Interventional Radiology guidelines, can often be managed without stenting or other invasive treatment.

CONCLUSIONS: This review update shows that the evidence is very uncertain about the effect of atherectomy on patency, mortality and cardiovascular event rates compared to plain balloon angioplasty, with or without stenting. We detected no clear differences in initial technical failure rates or TVR, but there may be reduced dissection and bailout stenting after atherectomy although this is uncertain. Included studies were small, heterogenous and at high risk of bias. Larger studies powered to detect clinically meaningful, patient-centred outcomes are required. PMID: 32990327 [PubMed - in process]
AbstractObjectivesWe aimed to compare the short ‐ and midterm results of perfusion strategies used for arch reconstruction surgery.Material and MethodsOne hundred and seventy ‐three consecutive patients who underwent aortic arch reconstruction surgery for transverse arcus hypoplasia between January 2011 and February 2020 were retrospectively analyzed. The patients were divided into two groups, as beating heart (BH) group and cardiac arrest (CA) group.ResultsThe CA group comprised 60 (35%) patients and the remaining 113 (65%) patients were in the BH group. The median age of the patients was 30 (interquartile range: 18 &...
Conclusions: Implantation of the p48MW/p48MW HPC is safe and effective for treatment of distally located cerebral aneurysms. Considering the reported rates of ischemic complications associated with flow diversion of complex bifurcation aneurysms, the p48MW/p48MW HPC potentially provides increased safety for complex bifurcation aneurysms in the anterior and posterior circulation.
