Abstract
BACKGROUND Treatment of chronic limb threatening ischemia (CLTI) poses a significant clinical challenge despite recent medical advancements. Chronic total occlusion (CTO) lesions make endovascular approaches to CLTI particularly challenging. Open proximal exposure with retrograde access and stenting (OPERAS) aims to solve this challenge through retrograde subintimal crossing of a CTO with direct visualization of proximal re-entry into the true lumen. We describe this novel technique and present its efficacy in eight patients. METHODS We conducted a retrospective case series at a single tertiary academic center. Data for patients who received OPERAS intervention included demographics, peri-operative details, and follow-up information. Statistical analysis was performed on length of stay, major post-operative complications, further intervention, clinical progression at 1 year, and amputation-free survival at 1 year. Immediate technical failure (ITF) and limb-based patency (LBP) at 1 year were calculated. RESULTS Nine limbs underwent OPERAS between January 2019 and March 2020. Inflow was achieved with common femoral artery endarterectomy. All limbs underwent balloon angioplasty and stenting of the SFA, and seven underwent the same procedure in the popliteal artery. ITF was 0% for all nine cases. There were no major post-operative complications, and ankle-brachial index significantly improved pre-and post-operatively (P < .001). Eight limbs (88.9%) sustained amputation-free survival at 1 year, and overall LBP was 67% at 1 year. CONCLUSION Our study presents a hybrid revascularization option to address severe, anatomically complex limbs (GLASS III) that lack a single autogenous conduit for open surgical revascularization. OPERAS addresses a main point of technical failure of subintimal techniques by directly visualizing the wire in the true lumen. Our data suggest that OPERAS can be effective to: (1) improve technical success of luminal re-entry following a subintimal approach; (2) address inflow concurrently with severe femoropopliteal disease; and (3) can be utilized when distal tissue loss is involved.

Technical Success and Complication Rates of Retrograde Arterial Access for Endovascular Therapy for Critical Limb Ischaemia: A Systematic Review and Meta-Analysis. Eur J Vasc Endovasc Surg 2020; 61:270-279. [PMID: 33358346 DOI: 10.1016/j.ejvs.2020.11.020] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 10/26/2020] [Accepted: 11/12/2020] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Antegrade crossing techniques via transfemoral access are often challenging and may be associated with technical and clinical failure when treating patients with critical limb ischaemia (CLI). The objective of this study was to summarise all available literature regarding retrograde endovascular treatment of patients with CLI and to investigate the technical success and complication rate of retrograde access. METHODS A systematic literature search was performed in PubMed, Scopus, and Cochrane Central until May 2020. A meta-analysis of 31 observational studies (29 retrospective and two prospective; 26 and five studies with low and moderate risk of bias, respectively) was conducted with random effects modelling. The incidence of adverse events peri-procedurally and during follow up were calculated. RESULTS The 31 studies enrolled 1 910 patients who were treated endovascularly for femoropopliteal and/or infrapopliteal lesions causing CLI. Most of the patients had diabetes while more than half of the overall population had coronary artery disease and dyslipidaemia. All lesions were located in the infra-inguinal segment and most were chronic total occlusions (96%; 95% CI 85%-100%). Seven studies reported moderate or severe calcification in approximately half of the cases (45%; 95% CI 30%-60%). The overall technical success of the retrograde approach was 96% (18 studies; 95% CI 92%-100%). Perforation, flow limiting dissection, distal embolisation, and local haematoma at the retrograde access site were infrequent and observed in 2.1%, 0.6%, 0.1%, and 1.3% of the patients, respectively. The six month primary patency rate was 78% (five studies; 95% CI 46%-99%), the six month limb salvage rate was 77% (four studies; 95% CI 70%-84%). CONCLUSION The results indicated that the retrograde or bidirectional antegrade/retrograde approach is safe and effective and facilitates angioplasty when antegrade treatment fails. However, prospective studies with standardised wound care and surveillance protocols are needed to investigate retrograde techniques in patients with CLI who failed antegrade revascularisation, to improve long term limb salvage and survival.

Facilitated Intravascular Ultrasound-Guided Balloon-Assisted Re-Entry Technique for Complex Lower-Extremity Chronic Total Occlusions: The FIBRE Technique. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2020; 30:65-69. [PMID: 33051094 DOI: 10.1016/j.carrev.2020.09.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 09/21/2020] [Accepted: 09/21/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To examine the efficacy and safety of the facilitated intravascular ultrasound (IVUS)-guided balloon assisted-re-entry (FIBRE) technique in the treatment of complex, chronic total occlusion (CTO) peripheral arterial lesions. METHODS A retrospective analysis of 150 patients undergoing peripheral intervention for lower extremity CTO was performed from 2014 to 2017 at two institutions. From the selected population, 10 patients with complex CTOs were identified using the FIBRE technique. Procedural success, 30 day and 6 month patency rates, ankle brachial index improvement, and complications were analyzed. RESULTS Ten out of 150 patients had the FIBRE technique utilized to attempt revascularization of a complex CTO of a femoropopliteal artery. Technical success was achieved in all 10 patients (100%). There were no intra-operative or peri-procedural complications reported including vessel perforation, bleeding, distal embolization, infrapopliteal vessel compromise, or infection. Arterial studies were obtained at 30 days and 6 months to assess patency in 9/10 patients (90%), with 1 patient being lost to follow up. Of the 9 patients, all 9 (100%) had documented arterial patency at both 30 days and 6 months. All patients reported improvement in symptoms. There were also no reports of re-intervention, amputation, or death at 6-month follow up. CONCLUSIONS The FIBRE technique is a safe and feasible strategy with excellent technical success in experienced hands for revascularization of complex lower extremity CTO when conventional modalities fail.

Abstract
PURPOSE To evaluate the use of the TruePath crossing device as the primary recanalization tool for infrainguinal chronic total occlusions (CTO). METHODS A retrospective analysis was conducted of 50 patients (mean age 75 years; 26 men) with 55 infrainguinal CTOs treated with the TruePath between March 2017 and September 2017 at a single center. The mean occlusion length was 138±55 mm, and femoropopliteal lesions accounted for 65% of the 55 lesions. The primary outcome measure was CTO crossing using the TruePath alone; secondary outcomes were assisted success (>50% lumen gain using the TruePath), device-related complications, and intraluminal crossing evaluated by intravascular ultrasound (IVUS). RESULTS Complete success was achieved in 33 (60%) of 55 lesions having a mean occlusion length of 145±72 mm. Among these, the true lumen crossing rate was 97% according to IVUS evaluation. Assisted success was achieved in 15 (68%) of the 22 failures. Complete/assisted success, in which the TruePath was thought to have contributed to CTO crossing, was attained in 48 (87%) of the 55 lesions. Three (5.5%) complications were observed: a perforation, an access-site hematoma, and acute occlusion; only the perforation was device related (1.8%). Multivariate analysis showed PACCS grade 4 (odds ratio 4.5, 95% confidence interval 1.33 to 15.5, p=0.02) was an independent predictor of TruePath failure. CONCLUSION Primary use of the TruePath crossing device for infrainguinal CTOs demonstrated a satisfactory complete success rate and a high rate of IVUS-documented intraluminal crossing with few device-related complications. Severe calcification is an independent predictor of TruePath failure.

Abstract
The aim of this study was to show limitation as well as potential of micro-endoscopy techniques as an innovative diagnostic and therapeutic approach in andrology. Two kinds of custom-made micro-endoscopes (ME) were tested in ex vivo vas deferens specimen and in post-mortem whole body. The semi-rigid ME included a micro-optic (0.9 mm outer diameter [OD], 10.000 pixels, 120° vision angle [VE], 3-20 mm field depth [FD]) and an integrated fibre-optic light source. The flexible ME was composed of a micro-optic (OD = 0.6 mm, 6.000 pixels, 120° VE, 3-20 mm FD). The ex vivo study included retrograde investigation of the vas deferens (surgical specimen n = 9, radical prostatectomy n = 3). The post-mortem investigation (n = 4) included the inspection of the vas deferens via both approaches. The results showed that antegrade and retrograde rigid endoscopy of the vas deferens were achieved as a diagnostic tool. The working channel enabled therapeutic use including biopsies or baskets. Using the flexible ME, the orifices of the ejaculatory ducts were identified. In vivo cadaveric retrograde cannulation of the orifices was successful. Post-mortem changes of verumontanum hindered the examinations beyond. Orifices were identified shaded behind a thin transparent membrane. Antegrade vasoscopy using flexible ME was possible up to the internal inguinal ring. Further advancement was impossible because of anatomical angle and lack adequate vision guidance. The vas deferens interior was clearly visible and was documented by pictures and movies. Altogether, the described ME techniques were feasible and effective, offering the potential of innovative diagnostic and therapeutic approaches for use in the genital tract. Several innovative indications could be expected.

Abstract
PURPOSE To report outcomes of a multicenter, nonrandomized study evaluating the safety and effectiveness of a guidewire-mounted mechanical recanalization device with a rotating distal tip (TruePath) in facilitating the crossing of infrainguinal chronic total occlusions (CTOs). METHODS Eligible patients had lower extremity ischemia and an angiographically confirmed occlusion, with no antegrade flow for at least 30 days, in an infrainguinal artery. Enrollment occurred when a previous or concurrent attempt to cross the CTO with a conventional guidewire had failed. A total of 85 patients with 85 lesions were enrolled; 61 (71.8%) target lesions were in the superficial femoral artery and 68 (80%) were considered moderately or heavily calcified. Clinical evaluations were assessed immediately post procedure and at 30-day follow-up. RESULTS Freedom from clinical perforation at the time of the procedure was achieved in 98.8% of patients. The device facilitated CTO crossing into the distal true lumen (technical success) in 68 (80.0%) patients, with subsequent distal guidewire positioning in 65 (76.5%). The average ABI (n=58) improved from 0.65 (range 0.35-1.20) at baseline to 1.00 (range 0.50-2.00) through 30-day follow-up. Symptoms improved in 70 (82.4%) patients upon treatment, and improvement was maintained in 57/70 (81.4%) through 30 days. CONCLUSION The ReOpen Study demonstrated that the TruePath device is safe and effective for facilitating crossing of CTOs resistant to conventional guidewire maneuvers.

Abstract
PURPOSE This prospective study aims to present the overall success rate, safety and long-term outcome of vibrational angioplasty technique, in the treatment of chronic total femoropopliteal occlusions in our institute. METHODS Between October 2000 and December 2008, patients with chronic total femoropoliteal arterial occlusions, treated with vibrational angioplasty during the same session after a failed attempt with conventional recanalization technique, were included. Patient's follow up included serial ankle-brachial index measurements and arterial duplex ultrasound examinations at 1, 3, 6, 12, 24, 36 and 48 months. RESULTS Twenty-seven patients (16 males and 11 females) and twenty-eight lesions were included in our study. Twenty-five lesions (89.3%) were successfully recanalized. Pain relief was noticed in twenty-one cases. From ten lesions with tissue loss (ulcer or gangrene) in successfully recanalized occlusions, six healed without major, or minor amputation. One non-healing amputation stump was healed after recanalization, without further complications. Four limbs underwent amputation (one minor and three major) despite successful recanalization, however all had an excellent healing of the amputation stump without further complications. The Kaplan-Meier test demonstrated 90%, 85% and 70% amputation-free survival rate at 12, 24 and 36 months, respectively. No major or minor complications were encountered. CONCLUSIONS Vibrational angioplasty is a safe, effective and durable endovascular technique for the treatment of chronic total occlusions in patients with limb ischemia that would be difficult to recanalize using conventional intraluminal techniques.
