Study of VentureMed ’ s Flex catheter begins in Switzerland

Vascular-focused device developer VentureMed said yesterday that it has launched another study of its Flex dynamic scoring catheter, this one to measure how open patients’ blood vessels remain 12 months after treatment. The prospective, single arm, non-randomized study in Switzerland will enroll up to 150 patients whose superficial femoral and popliteal arteries were scored by the Flex system before drug-eluting balloon angioplasty. Flex creates long, parallel, linear micro-incisions in all plaque-lined arteries. Dr. Daniel Périard and Dr. Rolf Engelberger, both of the angiology department at HFR- Hôpital Cantonal Fribourg, are the primary investigator and co-investigator of the BELONG study, which stands for BEnefit of arterial vessel preparation by LONGitudinal micro-incisions. “We believe preparing arterial vessels by delivering parallel longitudinal micro-incisions with the Flex system prior to drug-coated balloon angioplasty has the potential to demonstrate long-term clinical benefits for patients,” Periard said in a prepared statement. “Our early results have shown that arterial vessel preparation with the Flex system resulted in improved lumen expansion and vessel compliance after drug-coated balloon angioplasty, with a corresponding reduction in the rate of dissection.” “VentureMed Group is honored that such an accomplished group of interventionalists at an outstanding medical center in Switzerland will b...

We report a case of isolated septal myocardial infarction, in which the diagnosis was confirmed not by electrocardiographic, echocardiographic, or angiographic findings, but by nuclear imaging. A 46-year-old man with chest discomfort exhibited ST-segment elevations in leads V1 and V2, and borderline abnormalities of the septal wall motion on echocardiography. Emergency coronary angiography demonstrated delayed flow in the second septal branch of the left anterior descending coronary artery. Intravascular ultrasound showed plaque in the proximal portion of the septal branch without evidence of plaque rupture. No balloon ang...

Semin intervent Radiol 2019; 36: 084-090 DOI: 10.1055/s-0039-1688420Hepatic artery stenosis (HAS) is an infrequent complication of liver transplant; if left untreated, it can lead to hepatic artery thrombosis with high risk of biliary necrosis and graft loss. HAS is diagnosed with screening Doppler ultrasound, together with computed tomography angiography and magnetic resonance angiography. Endovascular treatment with angioplasty ± stent placement is safe and effective with infrequent major complications; however, when complications occur, they can devastate long-term graft survival. Herein, we present...

Authors: Sato T, Otsuka Y, Kikkawa Y, Iwasaki Y, Fukagawa M Abstract Vascular access failure, such as recurrent stenosis and thrombosis, is a major concern in patients with end-stage kidney disease. Neointimal hyperplasia development at the anastomosis site of outflow vessels is a primal cause for recurrent vascular access failure. We previously shed some lights into a role of vitamin D, which exerts a protective effect against neointimal hyperplasia formation. Virtual histology, derived from intravascular ultrasound technology, provides novel insights into plaque composition analysis in atherosclerotic diseases. H...

Authors: Shammas NW, Shammas WJ, Jones-Miller S, Radaideh Q, Shammas GA Abstract BACKGROUND: Luminal gain post balloon angioplasty (PTA) is in part due to the occurrence of dissections. The depth and extent of dissections, however, can influence the short- and long-term outcomes of a procedure. Focal force and scoring balloons have been used to reduce angiographic dissections post PTA. The role of the Flex Vessel Prep (VP) system (VentureMed Group), a dynamic, microincision, non-balloon based system, prior to PTA in reducing and/or limiting severe dissections has not been fully characterized. METHODS: In this p...

Blue arrows: edges of stent; red arrows: balloon edge markers (there will be an overhang of the balloon beyond the markers on either side); yellow arrow: guide catheter; violet arrow: angioplasty guide wire. Guide catheter is in left main coronary artery, guidewire and stent in left anterior descending coronary artery. Accurate visualization of the stent position and morphology is essential for good implantation technique. Stent has to be well expanded and apposed to the vessel wall to prevent stent thrombosis. But good visualization in a moving vessel is often challenging. Selecting a good view with less of movement is ...

We present a case of iatrogenic PVO and ipsilateral severe PVS following RFA who underwent attempted lobectomy for persistent exertional dyspnea and persistent hypoperfusion of the left upper lung lobe despite percutaneous intervention and six months of optimal medical therapy. The lobectomy was aborted due to the presence of a significant fibrothorax, and the patient continues to have significant exercise limitation despite participation in pulmonary rehabilitation.

ConclusionsAnteroposterior venography can indirectly diagnose obstruction of the left CIV through the identification of collaterals and pancaking. The combination of low sensitivity and a high rate of change of plan owing to IVUS precludes complete reliance on anteroposterior venography for the diagnosis of lesions in the left EIV and CFV and the right CIV, EIV, and CFV. IVUS must be used to comprehensively identify all venous iliofemoral lesions.

ConclusionAcute limb ischemia caused by an EXOSEAL vascular closure device is a very rare complication. Balloon angioplasty and stenting are considered to be effective options to deal with the plug dislodgement of an EXOSEAL vascular closure device. We must be prepared for every rare complication during endovascular treatment.
