Balloon-mounting stent versus balloon angioplasty for intracranial arterial stenosis: A systematic review and meta-analysis. J Stroke Cerebrovasc Dis 2024; 33:107631. [PMID: 38331010 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Revised: 02/01/2024] [Accepted: 02/05/2024] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND Intracranial artery atherosclerotic stenosis (ICAS) is a major cause of stroke, especially in Asian countries. Current treatment options, including balloon-mounted stent (BMS) and balloon angioplasty (BA), lack sufficient evidence to determine a preferred approach. This systematic review and meta-analysis aimed to compare the efficacy and safety of BMS and BA in treating ICAS. METHODS Following PRISMA 2020 guidelines, we conducted a comprehensive search in PubMed, Web of Science, and Scopus up to December 1, 2023. Eligible studies compared BMS with BA in patients diagnosed with ICAS. Primary outcomes included the success rate and occurrence of stroke (ischemic or hemorrhagic). Secondary outcomes were perforator occlusion, in-stent thrombosis, death, and restenosis. Statistical analysis was conducted using R software version 4.3.1, employing a random-effects model. RESULTS Five high-quality studies involving 707 patients (515 males, 192 females) were included. BMS had a significantly higher success rate compared to BA (Risk Ratio [RR]: 1.13; CI: 1.03 to 1.24, p < 0.01; I2 = 14 %). The overall risk for stroke (ischemic and hemorrhagic) was significantly higher in BMS (RR: 2.97; CI: 1.32 to 6.67, p < 0.01; I2 = 0 %). However, no significant difference was found between BMS and BA regarding ischemic stroke (RR: 2.33; CI: 0.80 to 6.74, p = 0.12; I2 = 0 %). Additionally, no significant differences were observed in terms of perforator occlusion, in-stent thrombosis, dissection, minor and major strokes, and mortality rates. BMS was associated with a lower risk of restenosis (RR: 0.31; 95 % CI: 0.12 to 0.83, p = 0.02; I2 = 0 %). CONCLUSION Our results indicate that BMS might be associated with higher success and lower restenosis rates than BA in the treatment of ICAS but with an increased overall risk of stroke. No significant differences were observed in ischemic stroke, perforator occlusion, in-stent thrombosis, dissection, minor and major strokes, and mortality rates. The choice of treatment should consider these findings, alongside the technical challenges and desired angiographic outcomes. Future randomized controlled trials are necessary to further elucidate these results.

Abstract
BACKGROUND A growing evidence on the correlation between hyperuricemia and cardiovascular disease (CVD) has been previously reported. However, there have been limited data on the impact of hyperuricemia on long-term clinical outcomes in patients with critical limb ischemia (CLI) who underwent percutaneous transluminal angioplasty (PTA). METHODS A total of 425 peripheral artery disease patients who underwent PTA for CLI were enrolled. The patients were divided into the hyperuricemia group (n = 101) and the normal group (n = 324). The primary endpoint was major adverse cerebral and cardiovascular event (MACCE), including death, myocardial infarction, any coronary revascularization, and stroke, up to 5 years. The secondary endpoint was a major adverse limb event (MALE), including any repeated PTA, and target extremity surgery. Inverse probability weighting (IPTW) analysis, derived from the logistic regression model, was performed to adjust for potential confounders. RESULTS After IPTW matching analysis, compared to the normal group, the hyperuricemia group was associated with a higher incidence of MACCE (20.7% vs. 13.6%, hazard ratio [HR], 1.65; 95% confidence interval [CI], 1.15-2.38, P = 0.006) including non-cardiac death (11.7% vs. 6.3%, HR: 1.95, 95% CI: 1.19-3.19, P = 0.006) and MALE (47.7% vs. 36.0%, HR: 1.62, 95% CI: 1.23-2.13, P = 0.001) including non-target extremity revascularization (15.0% vs. 6.8%, HR: 2.42, 95% CI: 1.52-3.84, P < 0.001). CONCLUSION In the present study, hyperuricemia was associated with worse clinical outcomes in patients with CLI following PTA during 5-year clinical follow-up. Efficacy of controlling hyperuricemia in improving clinical outcomes should be evaluated in further studies.

Abstract
BACKGROUND Delayed cerebral ischaemia (DCI) is a major cause of morbidity and mortality after aneurysmal subarachnoid haemorrhage (aSAH). Chemical angioplasty (CA) and transluminal balloon angioplasty (TBA) are used to treat patients with refractory vasospasm causing DCI. Multi-modal monitoring including brain tissue oxygenation (PbtO2) is routinely used at this centre for early detection and management of DCI following aSAH. In this single-centre pilot study, we are comparing these two treatment modalities and their effects on PbtO2. METHODS Retrospective case series of patients with DCI who had PbtO2 monitoring as part of their multimodality monitoring and underwent either CA or TBA combined with CA. PbtO2 values were recorded from intra-parenchymal Raumedic NEUROVENT-PTO® probes. Data were continuously collected and downloaded as second-by-second data. Comparisons were made between pre-angioplasty PbtO2 and post-angioplasty PbtO2 median values (4 h before angioplasty, 4 h after and 12 h after). RESULTS There were immediate significant improvements in PbtO2 at the start of intervention in both groups. PbtO2 then increased by 13 mmHg in the CA group and 15 mmHg in the TBA plus CA group in the first 4 h post-intervention. This improvement in PbtO2 was sustained for the TBA plus CA group but not the CA group. CONCLUSION Combined balloon plus chemical angioplasty results in more sustained improvement in brain tissue oxygenation compared with chemical angioplasty alone. Our findings suggest that PbtO2 is a useful tool for monitoring the response to angioplasty in vasospasm.

Transjugular approach in aspiration thrombectomy and angioplasty of a thrombosed straight arteriovenous graft compared to the direct hemodialysis access approach. Hemodial Int 2024; 28:162-169. [PMID: 38481062 DOI: 10.1111/hdi.13142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 02/17/2024] [Accepted: 02/20/2024] [Indexed: 04/13/2024]
Abstract
PURPOSE To evaluate the efficacy and outcome of the transjugular approach in endovascular recanalization of a thrombosed straight arteriovenous graft (AVG) compared to those of the direct hemodialysis access approach (conventional approach). MATERIALS AND METHODS We retrospectively assessed patients who underwent aspiration thrombectomy and percutaneous transluminal angioplasty for thrombosed straight AVG performed at a single institution between October 2006 and October 2021. A total of 138 thrombosed AVGs in 83 patients (39 male and 44 females) were divided into the transjugular approach group (Group A) and the conventional approach group (Group B). Technical and clinical success, postintervention primary patency, cumulative patency, and periprocedural complications were compared. RESULTS There was no statistical difference in demographic data between groups A and B. The technical success rate of group A and B was 96.4% (80/83) and 98.2% 54/55, respectively (p > 0.05). The mean procedure time was 61.4 min (Group A) and 70.5 min (Group B) (p > 0.05). There was no statistically significant difference between the two groups in postintervention primary patency. The cumulative patency of Groups A and B was 911.9 days (range 122-6277) and 1062.3 days (range 72-2302 days), respectively (p > 0.05). One patient in Group B experienced a major graft rupture. Pseudoaneurysm formation at the sheath insertion site occurred in two patients in Group B. No cases of stenosis or thrombosis of the IJV or hematoma at the puncture site were observed in Group A. CONCLUSION The transjugular approach is as safe and effective as the conventional approach for aspiration thrombectomy and percutaneous transluminal angioplasty of thrombosed straight AVGs.

Abstract
BACKGROUND Fibromuscular dysplasia is an idiopathic, segmental, nonatherosclerotic, noninflammatory vascular disease that can lead to arterial stenosis, tortuosity, occlusion, aneurysms, and dissection. Fibromuscular dysplasia is a rare cause of hypertension that can easily be missed. To date, there has been no definitive treatment for fibromuscular dysplasia. CASE REPORT In this report, we present an uncommon case of renovascular hypertension in a 21-year-old non-white female with a 3-year history of hypertension secondary to fibromuscular dysplasia involving bilateral renal arteries. Computed tomography angiography during the arterial phase revealed distal focal narrowing of the right main renal artery, distal focal narrowing of the left main renal artery, and proximal focal narrowing of the left accessory lower renal artery. Percutaneous balloon dilatation of the stenotic lesion was performed successfully up to 1 year After the procedure, the arterial blood pressure was within the normal range (110/70 to 125/75 mmHg) without medication. After 1 year of follow-up, CTA revealed re-stenosis in left main renal artery without clinical symptoms and normal blood pressure. Repeated procedure was done successfully. CONCLUSIONS This case report highlights the difficulty in the diagnosis and treatment of focal fibromuscular dysplasia in young non-white female patients. Computerized tomographic angiography is a useful tool for identifying the cause and showing the benefit of percutaneous transluminal renal angioplasty treatment for this rare entity, as an early percutaneous angioplasty intervention may have a clinical cure for hypertension.

Abstract
BACKGROUND Among patients with chronic limb-threatening ischemia (CLTI) and infrapopliteal artery disease, angioplasty has been associated with frequent reintervention and adverse limb outcomes from restenosis. The effect of the use of drug-eluting resorbable scaffolds on these outcomes remains unknown. METHODS In this multicenter, randomized, controlled trial, 261 patients with CLTI and infrapopliteal artery disease were randomly assigned in a 2:1 ratio to receive treatment with an everolimus-eluting resorbable scaffold or angioplasty. The primary efficacy end point was freedom from the following events at 1 year: amputation above the ankle of the target limb, occlusion of the target vessel, clinically driven revascularization of the target lesion, and binary restenosis of the target lesion. The primary safety end point was freedom from major adverse limb events at 6 months and from perioperative death. RESULTS The primary efficacy end point was observed (i.e., no events occurred) in 135 of 173 patients in the scaffold group and 48 of 88 patients in the angioplasty group (Kaplan-Meier estimate, 74% vs. 44%; absolute difference, 30 percentage points; 95% confidence interval [CI], 15 to 46; one-sided P<0.001 for superiority). The primary safety end point was observed in 165 of 170 patients in the scaffold group and 90 of 90 patients in the angioplasty group (absolute difference, -3 percentage points; 95% CI, -6 to 0; one-sided P<0.001 for noninferiority). Serious adverse events related to the index procedure occurred in 2% of the patients in the scaffold group and 3% of those in the angioplasty group. CONCLUSIONS Among patients with CLTI due to infrapopliteal artery disease, the use of an everolimus-eluting resorbable scaffold was superior to angioplasty with respect to the primary efficacy end point.

Abstract
BACKGROUND The purpose of the study is to evaluate the efficacy of thromboendarterectomy (TEA) for common femoral occlusive disease using bovine pericardium patch angioplasty. METHODS The subjects were patients who underwent TEA for common femoral occlusive disease with bovine pericardium patch angioplasty from October 2020 to August 2021. The study had a prospective, multicenter, and observational design. The primary end point was primary patency (freedom from restenosis). The secondary end points were secondary patency, amputation-free survival (AFS), postoperative wound complication, hospital death within 30 days, and major adverse cardiovascular events (MACE) within 30 days. RESULTS Forty-seven TEA procedures with a bovine patch were performed in 42 patients (34 males; median age, 78 years; diabetes mellitus, 57%; end-stage renal disease with hemodialysis, 19%). Clinical presentations were intermittent claudication (68%) and critical limb-threatening ischemia (32%). Sixteen (34%) limbs underwent TEA alone and 31 (66%) underwent a combined procedure. Surgical site infection (SSI) occurred in 4 limbs (9%) and lymphatic fistulas in 3 limbs (6%). One limb with SSI required surgical debridement 19 days after the procedure, and 1 limb (2%) without postoperative wound complications required additional treatment due to acute bleeding. Hospital death within 30 days occurred in 1 case due to panperitonitis. There was no MACE within 30 days. Claudication was improved in all cases. Postoperative ABI of 0.92 [0.72-1.00] was significantly higher than the preoperative value (P < 0.001). The median follow-up period was 10 months [9-13 months]. One limb (2%) required additional endovascular therapy due to stenosis at the endarterectomy site at 5 months postoperatively. Primary and secondary patencies were 98% and 100% at 12 months, respectively, and the AFS rate was 90% at 12 months. CONCLUSIONS Common femoral TEA with bovine pericardium patch angioplasty has satisfactory clinical outcomes.

Abstract
BACKGROUND To assess the clinical effects of diabetic peripheral neuropathy (DPN) in patients with chronic limb-threatening ischemia (CLTI) treated by primary infrapopliteal angioplasty for neuro-ischemic Rutherford 5, foot wounds. MATERIALS AND METHODS Over a 10-year period (2009-2019), a series of 304 diabetic ischemic limbs adding or not evincible neuropathic affectation were treated by primary infrapopliteal angioplasty and their files were retrospectively reviewed. Mean length of treated arterial lesions was 6.1 cm (range 1-22 cm). Inferior limb vibration perception threshold diagnostic was performed for comparing and scoring detectable DPN in all studied diabetic patients (classed from 0 to 10 points). There were 19% limbs with normal (0-1 points) perception (group 1), 55% others with "mild" and "moderate" (2-6 points) neuropathic impairment (group 2), and 26% limbs showing "severe" (7-10 points) DPN (group 3). RESULTS Primary infrapopliteal angioplasty succeeded in 89% cases in group 1, in 82% in group 2, and in 68% of limbs in group 3. This latest group assembled the heaviest neuropathic affectation and arterial calcifications and proved the lowest clinical benefit at 36 months: 35% (95% confidence interval [CI]=22% to 48%) of primary patency, 36% (95% CI=22% to 50%) wound healing, and 54% (95% CI=39% to 69%) limb preservation rates. A comparison between groups 1 vs 3 and 2 vs 3 of primary patency (p=0.014 and p=0.043), tissue healing (p=0.049 and p=0.01), and limb salvage (p=0.006 and p=0.023) proved significant, yet without statistical weight for group 1 vs 2 (p>0.05). Overall survival was not significantly affected between groups (p=0.34). CONCLUSION The presence of severe DPN may jeopardize the results of infrapopliteal angioplasty in terms of patency, tissue cicatrization, and limb preservation, yet without significance on survival of these patients. When present, DPN requires appropriate stratification as specific indicator in CLTI treatment.

Abstract
Introduction. Contrast Induced Encephalopathy (CIE) belongs to Major Adverse Renal and Cardiovascular Events (MARCE) after iodinated contrast medium (IOCM), especially for high-risk patients with several comorbidities such as hypertension, diabetes, heart failure, and Chronic Kidney Disease (CKD). We report a case of CIE in a Peritoneal Dialysis (PD)-patient. Case report. A 78-year-old, affected by diabetes, hypertension, chronic heart failure, and End Stage Renal Disease (ESRD) treated with PD, underwent a carotid Percutaneous Angioplasty (PTA). Immediately after the exam, he developed mental confusion and aphasia. Encephalic CT scan and MRI excluded acute ischemia or hemorrhage but showed cerebral oedema. Mannitol and steroids were administered and additional PD exchange was performed with depurative aim. Within 2 days the patient completely recovered. Discussion. CIE mimics severe neurological diseases. It should be considered as a differential diagnosis if symptoms occur immediately after administration of IOCM, especially in high-risk patients and in case of intra-arterial injection. Clinical presentation includes transient cortical blindness, aphasia, focal neurological defects, and confusion. CIE is often a diagnosis of exclusion, and imaging plays a significant role. Symptoms generally resolve spontaneously within 24-48h, rarely in few days. Symptomatic therapy, including mannitol and steroids could be considered. In literature, CIE is reported only in a few patients affected by ESRD treated with chronic HD, and our is the first available case of a patient treated with chronic PD who developed this rare complication.

Abstract
BACKGROUND To access the efficacy of percutaneous transluminal angioplasty and arteriovenous fistula reconstruction for immature arteriovenous fistula, compare the long-term patency and post-operative complications between them. MATERIALS AND METHODS The medical records and Hemodialysis record sheets from 44 patients between May 2020 and January 2022 who underwent percutaneous transluminal angioplasty or arteriovenous fistula reconstruction treatment for immature autogenous arteriovenous fistula (AVF) were retrospectively reviewed. The patients were divided into two groups according to the type of surgery they received, including 25 patients in the PTA group and 19 patients in the AVF reconstruction group. Clinical outcomes were included, such as the primary and secondary patency rates following the procedure, maturation time, peak systolic velocity (PSV) of brachial artery, maximum pump-controlled blood flow at initial dialysis, and post-operative complications rates in the two groups. RESULTS Technical and clinical success was achieved in 100% of the 44 cases. For patients who underwent percutaneous transluminal angioplasty, the primary patency rate at 3, 6, and 9 months was 84.0%, 68.0%, 60.0%, and the secondary patency rate was 92.0%, 84.0%, 80.0%, respectively. And for patients who underwent arteriovenous fistula reconstruction, the primary patency rate at 3, 6, and 9 months was 89.5%, 73.7%, 68.4%, and the secondary patency rate was 100.0%, 94.7%, 94.7%, respectively. There were no significant differences between the two groups in terms of patency rates (p > .050). In patients whose maturation was successful, the average maturation time of fistula after the PTA procedure was 19.36 ± 13.94 days, and 58.63 ± 18.95 days for the reconstruction procedure (p < .010). The PSV of brachial artery before and after the procedure was 87.64 ± 23.87 cm/s and 153.20 ± 21.69 cm/s in PTA group, for reconstruction group, the number was 86.26 ± 20.59 cm/s and 151.26 ± 29.94 cm/s, respectively. No statistically significant differences (p > .050). The maximum pump-controlled blood flow at initial dialysis was 232.60 ± 16.72 ml/min in PTA group, which was significantly higher than 197.11 ± 10.45 ml/min in reconstruction group (p < .010). Subcutaneous hematoma, restenosis, thrombus formation, and pseudoaneurysm were major complications in PTA group. Restenosis, thrombus formation, and pseudoaneurysm were major complications in reconstruction group, with no statistically significant differences between the two groups (p > .050). CONCLUSION When immature AVFs require reconstruction surgery, the patency outcomes are comparable to AVFs that undergo successful management by PTA. While, when AVFs are successfully managed by PTA, they have significantly less maturation times and higher maximum pump-controlled blood flow rates at initial dialysis AVF use.

Abstract
ABSTRACTRecurring and rapidly developing (flash) pulmonary edema is the hallmark of Pickering syndrome, affecting patients with hypertension and atherosclerotic renal artery stenosis (either bilateral or unilateral) in a solitary functioning kidney, and impaired renal function. We herein report on a series of consecutive patients with recurrent hospital admissions for pulmonary edema, impaired renal function (chronic kidney disease class 4-5), and atherosclerotic bilateral renal artery stenosis, in whom Pickering syndrome had been long neglected. We also describe a streamlined diagnostic strategy entailing little or no need for contrast medium, thus carrying no risks of further worsening of renal function. This allowed us to make the correct diagnosis and opened the way to revascularization by percutaneous transluminal renal angioplasty with stent, which provided swift recovery of kidney function with resolution of pulmonary congestion and long-term pulmonary edema- and dialysis-free survival in all cases. In summary, these findings support the following key messages: (1) considering the diagnosis of Pickering syndrome, followed by searching atherosclerotic renal artery stenosis, is an essential step toward a life-saving revascularization that avoids dialysis and an otherwise poor outcome; and (2) a simplified strategy entailing little or no need for contrast medium, carrying no associated risks of deteriorating renal function, permits the diagnosis of Pickering syndrome.

Abstract
OBJECTIVES The aim of this study is to identify the peri-procedural risk factors and outcomes of hemodynamic instability (HI) after carotid artery stenting (CAS). METHODS A single-center, retrospective study was performed in 168 patients who underwent CAS procedure between September 2017 and September 2020. The presence of HI, as defined by hypertension (systolic blood pressure >160 mmHg), hypotension (systolic blood pressure <90 mmHg), and/or bradycardia (heart rate <60 bpm), was recorded. Long-period HI was defined as persistent HI lasting more than 24 h. Patient demographics, comorbidities, peri-procedural variables, and risk factors were recorded. Clinical outcomes including cerebral hyperperfusion syndrome, hemorrhage, transient ischemic attack (TIA), stroke, myocardial infarction, and mortality within 30 days of the procedure were evaluated. Logistic regression was used to analyze the independent risk factors of long-period HI following CAS. RESULTS Among 168 patients (mean age, 68.2 ± 8.3 years; 81.5% male), the frequency of post-procedural long-period HI was noted in 42 patients (25.0%). Male was prone to experience HI (odds ratio, 9.156, p = 0.021). Aggressive inflation pressure (>7 atm) and 5 mm balloon for pre-dilatation were risk factors of long-period HI (OR, 7.372, p = 0.035; OR, 3.527, p = 0.023). Intraoperative peak blood pressure and larger-sized stents remained independent predictors for the development of HI (OR, 1.043, p = 0.027, and OR, 1.973, p = 0.015). Patients with prolonged HI were more likely to suffer TIA and stroke compared to other patients and significant difference was found in the occurrence of TIA (p < 0.05). Non-significance was found in mortality rate and other outcomes. CONCLUSIONS CAS-induced HI occurs in a considerable percentage while several peri-procedural variables are determined as independent predictors to develop long-period HI. Patients with prolonged HI are associated with increased risk of neurologic events and thus standardized intervention as well as management of long-period HI are of critical importance during clinical process.

Abstract
BACKGROUND Peripheral arterial disease (PAD) affects a substantial proportion of the global population, particularly older individuals, affecting around 200 million people worldwide highlighting its significant impact on human health. Critical limb ischemia (CLI) is the most severe clinical presentation of PAD characterized by ischemic rest pain tissue ulceration or gangrene. The objective of the study is to assess the efficacy of infra popliteal angioplasty (in terms of wound healing and limb salvage) in patients with below-the-knee total chronic occlusion (TCO). METHODS In this cross-sectional study, all consecutive patients in one year with TCO and fulfilling the inclusion criteria were included. RESULTS A total of 64 limbs underwent angioplasty. The mean age was 55.38 ± 13.12 (Range 22-88) years and there were 73% (n=47) males. Diabetes mellitus was the most prevalent risk factor in 59.4% (n=38) of patients. 48.4 % (n=31) of patients had below-knee TCO in all three arteries. Technical Success was achieved in 95.3% (n=61/64). All 3 patients who had technical failure ended up with below-the-knee amputation. Furthermore, 2 more patients who had technical success also ended up with below-the-knee amputation. The difference between these two rates was significant (100% vs 3.3%; p-value =0.004). In terms of wound healing, statistically significant improvement was noted within the first 6 months (p-value = 0.05). The limb salvage rate was 90.6% (n=59/64). The primary patency rate was 81.3% (n=52) and 76.6% (n=49) at 6 and 12 months respectively. CONCLUSIONS Angioplasty results in statistically significant wound healing leading to a higher limb salvage rate, in patients with TCO of infrapopliteal arteries.

Abstract
BACKGROUND The efficacy and safety of percutaneous transluminal pulmonary angioplasty (PTPA) for Takayasu arteritis-associated pulmonary hypertension (TA-PH) remain unclear. OBJECTIVES To examine the efficacy and safety of PTPA in TA-PH. METHODS PubMed, Embase, and the Cochrane Central Register of Controlled Trials Library were searched from inception to August 18, 2022, for articles investigating the efficacy and safety of PTPA for TA-PH. The primary efficacy outcomes were pulmonary vascular resistance (PVR) changes from baseline to re-evaluation and 6-minute walking distance (6MWD). The safety outcome was procedure-related complications. RESULTS Five articles comprising 104 patients with TA-PH who underwent PTPA were included. The scores of article quality, as assessed using the methodological index for nonrandomized studies tool, were high, ranging from 13 to 15 points. The pooled treatment effects of PVR (weighted mean difference [WMD]: -4.8 WU; 95% confidence interval [CI]: -6.0 to -3.5 WU; I2 = 0.0%), 6MWD (WMD: 101.9 m; 95% CI: 60.3-143.6 m; I2 = 70.4%) significantly improved. Procedure-related complications, which predominantly present as pulmonary artery injury and pulmonary injury, occurred in 32.0% of the included patients. Periprocedural death occurred in one patient (1.0%, 1/100). CONCLUSIONS Patients with TA-PH could benefit from PTPA in terms of hemodynamics and exercise tolerance, at the expense of procedure-related complications. PTPA should be encouraged to enhance the treatment response in TA-PH. These findings need to be confirmed by further studies, ideally, randomized controlled trials.

Abstract
Pulmonary vein occlusion (PVO) is a known complication of radiofrequency ablation for atrial fibrillation. We present a case with delayed presentation leading to chronic total PVO. Computed Tomography (CT) imaging did not predict the presence of residual flow. Despite this, the occlusion was successfully stented using wire escalation techniques adapted from chronic total occlusion coronary angioplasty, with resolution of symptoms. This emphasises the importance of combining CT with invasive angiography for patient selection and interventional strategy. Innovative angioplasty techniques used to overcome PVO need to be balanced against additional risk of perforation when dealing with extra-cardiac structures.

Prospective, randomized, multicenter clinical study comparing a self-expanding covered stent to percutaneous transluminal angioplasty for treatment of upper extremity hemodialysis arteriovenous fistula stenosis. Kidney Int 2023; 104:189-200. [PMID: 36990214 DOI: 10.1016/j.kint.2023.03.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 03/02/2023] [Accepted: 03/09/2023] [Indexed: 03/29/2023]
Abstract
Use of a covered stent after percutaneous transluminal angioplasty (PTA) was compared to PTA alone for treatment of upper extremity hemodialysis patients with arteriovenous fistula (AVF) stenoses. Patients with AVF stenosis of 50% or more and evidence of AVF dysfunction underwent treatment with PTA followed by randomization of 142 patients to include a covered stent or 138 patients with PTA alone. Primary outcomes were 30-day safety, powered for noninferiority, and six-month target lesion primary patency (TLPP), powered to test whether TLPP after covered-stent placement was superior to PTA alone. Twelve-month TLPP and six-month access circuit primary patency (ACPP) were also hypothesis tested while additional clinical outcomes were observed through two years. Safety was significantly non-inferior while six- and 12-month TLPP were each superior for the covered stent group compared to PTA alone (six months: 78.7% versus 55.8%; 12 months: 47.9% versus 21.2%, respectively). ACPP was not statistically different between groups at six-months. Observed differences at 24 months favored the covered-stent group: 28.4% better TLPP, fewer target-lesion reinterventions (1.6 ± 1.6 versus 2.8 ± 2.0), and a longer mean time between target-lesion reinterventions (380.4 ± 249.5 versus 217.6 ± 158.4 days). Thus, our multicenter, prospective, randomized study of a covered stent used to treat AVF stenosis demonstrated noninferior safety with better TLPP and fewer target-lesion reinterventions than PTA alone through 24 months.

Abstract
BACKGROUND Endovascular therapy, such as percutaneous transluminal angioplasty (PTA), stenting, or embolization, is a well-established form of treatment to prolong the lifespan of arteriovenous access. These procedures, especially PTA, can be accompanied with severe pain. We reviewed and analyzed the efficacy, safety, and outcome of sedoanalgesia using intravenous midazolam and fentanyl, for pain relief during these procedures. METHODS Two hundred and two consecutive patients with dysfunctional dialysis access that had undergone endovascular procedure in our institute between July and November 2017 were included in this study. The dialysis access profile, procedure complication, and 10-point Visual Analog Scale (VAS) were collected. One-year clinical follow-up record was also collected to evaluate arteriovenous access patency and long-term complications. RESULTS Among the 202 patients, the mean age was (mean ± SD) 67.0 ± 12.08 years. Dialysis access profile of these patients were 119 (58.9%) native arteriovenous fistula and 162 (74.2%) forearm access. The number of lesions treated were 1.63 ± 0.802.Immediate complications included 11 (5.44%) nausea/vomiting, 24 (11.88%) desaturation (SpO2 < 90%, resolved after pillow removal or jaw trust), 16 (7.9%) hypotension (SBP < 90 mmHg, resolved without inotropic agents). There was a low average pain score (1.16 ± 1.594) during the procedure with 136 (67.3%) no pain (VAS 0-1) and 56 (27.7%) mild pain (VAS 2-4). Higher VAS score correlated with overweight patients, longer PTA time and pain after procedure. Six-month primary patency rate was 49.17% and primary assisted patency rate was 93.04%. CONCLUSIONS Sedoanalgesia with intravenous midazolam and fentanyl is an easy, safe, and effective method for surgeons.

Abstract
This paper analyzes the effects of hospital volume on outcomes of patients undergoing percutaneous transluminal angioplasty (PTA) with stent implant in Slovakia between 2014 and 2019. The volume-outcome relationship is estimated jointly using a discrete factor approach, where choice of hospital is correlated with durations until readmission or death, accounting for observed and unobserved characteristics. The results reveal the importance of controlling for between-hospital differences and selectivity in patient referral. Estimates without hospital fixed effects overstate the positive effect of volume on outcomes, but the results remain statistically significant. Once selectivity is accounted for in the joint correlated model, the positive volume-outcome relationship is not different from zero. Overall, the main driver of the volume-outcome relationship for PTA procedures appears to be related to selective referral and differences in quality of health care providers.

Abstract
OBJECTIVE Surgical thromboendarterectomy (TEA) is the standard treatment for an occlusive lesion of the common femoral artery (CFA). However, there is limited knowledge on the need for patch angioplasty in CFA TEA. The objective of this study was to compare the peri-operative and two year results of CFA TEA with or without patch angioplasty. METHODS A multicentre retrospective observational study was performed at 34 Japanese centres. Comparisons were made between patients undergoing CFA TEA with or without patch angioplasty after propensity score matching (PSM). The primary endpoints were primary patency and freedom from target lesion revascularisation (TLR) of the TEA lesion. The secondary endpoints were hospital outcomes, limb salvage, and overall survival. RESULTS Between 2018 and 2020, 428 TEA procedures (237 with patch angioplasty and 191 with primary closure) were performed. PSM extracted 151 pairs with no significant intergroup differences in baseline characteristics. Peri-operative death and complications occurred in 0.7% vs. 1.3% (p = 1.0) and 6.0% vs. 6.6% (p = 1.0), respectively. The follow up rate was 96% over a median follow up of 14.9 months (interquartile range 8.3, 24.3). Loss of primary patency occurred in 18 patients. The two year primary patency of patch angioplasty cases was statistically significantly higher than that of primary closure cases (97.0% vs. 89.9%; p = .021). TLR was performed in 14 patients. The two year freedom from TLR in patch angioplasty cases was also statistically significantly higher than in primary closure cases (98.6% vs. 92.9%; p = .003). During follow up, seven limbs required major amputation and 40 patients died. There was no statistically significant difference in limb salvage and survival between the two groups after PSM. CONCLUSIONS This is the first report to show that patch angioplasty may decrease re-stenosis and target lesion revascularisation of CFA TEA lesions.

Abstract
BACKGROUND Intracranial artery stenosis (ICAS) is an arterial narrowing in the brain that can cause stroke. Endovascular therapy (ET) and conventional medical treatment (CMT) may prevent recurrent ischaemic stroke caused by ICAS. However, there is no consensus on the best treatment for people with ICAS. OBJECTIVES To evaluate the safety and efficacy of endovascular therapy plus conventional medical treatment compared with conventional medical treatment alone for the management of symptomatic intracranial artery stenosis. SEARCH METHODS We searched the Cochrane Stroke Group Trials Register, CENTRAL, MEDLINE, Embase, four other databases, and three trials registries on 16 August 2022. We contacted study authors and researchers when we required additional information. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing ET plus CMT with CMT alone for the treatment of symptomatic ICAS. ET modalities included angioplasty alone, balloon-mounted stent, and angioplasty followed by placement of a self-expanding stent. CMT included antiplatelet therapy in addition to control of risk factors such as hypertension, hyperlipidaemia, and diabetes. DATA COLLECTION AND ANALYSIS Two review authors independently screened the records to select eligible RCTs, then extracted data from them. We resolved any disagreements through discussion, reaching consensus decisions among the full team. We assessed risk of bias and applied the GRADE approach to assess the certainty of the evidence. The primary outcome was death by any cause or non-fatal stroke of any type within three months of randomisation. Secondary outcomes included all-cause death or non-fatal stroke of any type occurring more than three months after randomisation, ipsilateral stroke, transient ischaemic attack, ischaemic stroke, haemorrhagic stroke, death, restenosis, dependency, and health-related quality of life. MAIN RESULTS We included four RCTs with 989 participants who had symptomatic ICAS, with an age range of 18 to 85 years. We identified two ongoing RTCs. All trials had high risk of performance bias, as it was impossible to blind participants and personnel to the intervention. Three trials were terminated early. One trial was at high risk of attrition bias because of substantial loss to follow-up after one year and a high proportion of participants transferring from ET to CMT. The certainty of evidence ranged from low to moderate; we downgraded for imprecision. Compared to CMT alone, ET plus CMT probably increases the risk of short-term death or stroke (risk ratio (RR) 2.93, 95% confidence interval (CI) 1.81 to 4.75; 4 RCTs, 989 participants; moderate certainty), short-term ipsilateral stroke (RR 3.26, 95% CI 1.94 to 5.48; 4 RCTs, 989 participants; moderate certainty), short-term ischaemic stroke (RR 2.24, 95% CI 1.30 to 3.87; 4 RCTs, 989 participants; moderate certainty), and long-term death or stroke (RR 1.49, 95% CI 1.12 to 1.99; 4 RCTs, 970 participants; moderate certainty). Compared to CMT alone, ET plus CMT may increase the risk of short-term haemorrhagic stroke (RR 13.49, 95% CI 2.59 to 70.15; 4 RCTs, 989 participants; low certainty), short-term death (RR 5.43, 95% CI 1.21 to 24.40; 4 RCTs, 989 participants; low certainty), and long-term haemorrhagic stroke (RR 7.81, 95% CI 1.43 to 42.59; 3 RCTs, 879 participants; low certainty). It is unclear if ET plus CMT compared with CMT alone has an effect on the risk of short-term transient ischaemic attack (RR 0.79, 95% CI 0.30 to 2.07; 3 RCTs, 344 participants; moderate certainty), long-term transient ischaemic attack (RR 1.05, 95% CI 0.50 to 2.19; 3 RCTs, 335 participants; moderate certainty), long-term ipsilateral stroke (RR 1.78, 95% CI 1.00 to 3.17; 4 RCTs, 970 participants; moderate certainty), long-term ischaemic stroke (RR 1.56, 95% CI 0.77 to 3.16; 4 RCTs, 970 participants; moderate certainty), long-term death (RR 1.61, 95% CI 0.77 to 3.38; 4 RCTs, 951 participants; moderate certainty), and long-term dependency (RR 1.51, 95% CI 0.93 to 2.45; 4 RCTs, 947 participants; moderate certainty). No subgroup analyses significantly modified the effect of ET plus CMT versus CMT alone. The trials included no data on restenosis or health-related quality of life. AUTHORS' CONCLUSIONS This review provides moderate-certainty evidence that ET plus CMT compared with CMT alone increases the risk of short-term stroke and death in people with recent symptomatic severe ICAS. This effect was still apparent at long-term follow-up but appeared to be due to the early risks of ET; therefore, there may be no clear difference between the interventions in terms of their effects on long-term stroke and death. The impact of delayed ET intervention (more than three weeks after a qualifying event) warrants further study.

Abstract
OBJECTIVE Patch angioplasty during carotid endarterectomy (CEA) is commonly used to treat carotid artery stenosis. However, the choice of which patch to use remains a matter of debate. Autologous venous material has disadvantages such as wound-related problems at the harvest site and a prolonged intervention time. These limitations can be bypassed when synthetic or biological patches are used. Both materials have been associated with divergent advantages and disadvantages. Therefore, the aim of our study was to compare the long-term follow-up outcomes in patients who underwent CEA and closure with either a bovine pericardial patch (BPP) or polyester patch. METHODS A retrospective cohort study was conducted including all patients who underwent primary CEA and closure with a BPP or a polyester patch between January 2010 and December 2020 at our tertiary referral center. In 2015, the BPP was introduced as an alternative for polyester. The primary outcome was the occurrence of transient ischemic attack (TIA) or cerebrovascular accident (CVA) during follow-up and secondary outcomes included restenosis, reintervention, all-cause mortality, and patch infection. Cox proportional hazard models were used and hazard ratios with 95% confidence intervals were used to predict these outcomes. RESULTS We included 417 CEA patients; 254 patients (61%) received a BPP and 163 received (39%) a polyester patch. The mean age was 70.2 ± 8.7 years and 67% were male. The median follow-up time was 15 months (range, 12-27 months) for BPP and 42 months (range, 16-60 months) for polyester (P < .001). Postoperative hematoma (≤30 days) was significantly lower in the BPP cohort (2% BPP vs 6% polyester; P = .047). No other significant differences on short-term outcomes were found. Univariable Cox regression analyses showed no significant differences between the effect estimates of polyester and BPP on TIA or CVA (P = .106), restenosis (P = .211), reintervention (P = .549), or all-cause mortality (P = .158). No significant differences were found after adjusting for confounders in the multivariable analyses: TIA or CVA (P = .939), restenosis (P = .057), reintervention (P = .193) and all-cause mortality (P = .742). Three patients with a polyester patch had patch infection compared with none of the patients in the group who received a BPP. CONCLUSIONS This large retrospective study showed comparable safety and durability of both BPP and polyester suggesting that both patch types can be safely applied for CEA with patch angioplasty. Patch infection was rare and was absent in the BPP group.

Abstract
Patients with posterior circulation ischemia due to vertebral artery stenosis account for 20 to 25% of ischemic strokes and have an increased risk of recurrent stroke. In patients treated with medical therapy alone, the risk of recurrence is particularly increased in the first few weeks after symptoms occur, with an annual stroke rate of 10 to 15%. Additionally, obstructive disease of the vertebrobasilar system carries a worse prognosis, with a 30% mortality at 2-years if managed medically without additional surgical or endovascular intervention. Percutaneous transluminal angioplasty and stenting of symptomatic vertebral artery stenosis are promising options widely used in clinical practice with good technical results; however, the improved clinical outcome has been examined in various clinical trials without a sufficient sample size to conclusively determine whether stenting is better than medical therapy. Surgical revascularization is an alternative approach for the treatment of symptomatic vertebral artery stenosis that carries a 10-20% mortality rate. Despite the advances in medical therapy and endovascular and surgical options, symptomatic vertebral artery stenosis continues to impose a high risk of stroke recurrence with associated high morbidity and mortality. This review aims to provide a focused update on the percutaneous treatment of vertebral artery stenosis, its appropriate diagnostic approach, and advances in medical therapies.

Abstract
OBJECTIVE Bovine pericardial patch (BPP) is currently used in femoral angioplasty as an alternative for autologous vein patch (AVP), but studies comparing the results of the two methods are scarce. In this retrospective study, we aimed to discover the differences between BPP and AVP closure in long-term durability. METHODS This study consisted of all femoral endarterectomies with BPP closure performed in Helsinki University Hospital from January 1, 2014, to December 31, 2017. For comparison, the same number of consecutive patients who underwent femoral endarterectomy with AVP closure from January 1, 2014, to October 16, 2016, were reviewed. Follow-up ended December 31, 2020. The mean follow-up was 19 months (range, 0-74 months) in the BPP group and 22 months (range, 0-79 months) in the AVP group. The primary endpoint was primary patency. Secondary endpoints were restenosis at patch site detected by imaging or perioperatively, patch rupture, and deep surgical wound infection. Propensity score analysis was performed for adjustment of differences between the AVP and BPP groups. RESULTS Overall primary patency was superior in the AVP group compared with the BPP group: at 1 year, 96.5% vs 85.0% and at 5 years, 83.0% vs 72.3% (P = .04). In propensity score-matched pairs (n = 92), no difference was found between the groups in primary patency: 95.7% and 95.7% at 1 year and 92.5% and 78.6% at 5 years (P = .861) or in freedom from restenosis: 100% and 100% at 1 year and 89.1% and 84.0% at 5 years (P = .057). Deep wound infections occurred slightly more often after BPP closure (8%) than after AVP closure (4%), but the difference was not statistically significant (P = .144). There were no patch ruptures in the BPP group, but in the AVP group, there were five ruptures (3.5%) (P = .024). CONCLUSIONS BPP is compatible to AVP in femoral endarterectomy in patency and can be regarded as the safer choice considering the risk of patch rupture.

Effect of Percutaneous Endovascular Angioplasty Combined with Negative Pressure Drainage on the "One-Stop" Treatment of Ischemic Diabetic Foot Ulcer. Ann Vasc Surg 2022; 92:272-284. [PMID: 36586666 DOI: 10.1016/j.avsg.2022.12.066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 11/20/2022] [Accepted: 12/04/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND To explore the therapeutic effect, safety, and economic benefit of a "one-stop" diagnosis and treatment mode of vascular surgery for ischemic diabetic foot (DF) ulcer and to analyze the associated and independent factors that affect ulcer healing. METHODS In a prospective, single-center study, patients with ischemic DF ulcers from January 2017 to July 2021 were treated with either percutaneous endovascular angioplasty combined with negative pressure closed drainage (PTA-VSD) or percutaneous endovascular angioplasty combined with depuration (PTA-UD). The effectiveness and economic benefits of the 2 measures were compared, and independent factors affecting ulcer healing were explored via univariate and logistic regression analyses. RESULTS Fifty patients with ischemic DF ulcer (25 patients in the PTA-VSD group and 25 patients in the PTA-UD group; 40 males and 10 females) were included, with an average age of 67.74 ± 10.71 years. No difference was observed in the demographic data. The findings showed that the ulcer healing time in the PTA-VSD group was significantly shorter than that in the PTA-UD group (154.79 vs. 238.31 days), and the ulcer healing rate at 180 days post surgery was significantly greater in the PTA-VSD group (52% vs. 12%) (P = 0.002, < 0.05). The ulcer score in the PTA-VSD group decreased significantly at 3, 6, and 12 months post surgery. The duration of hospitalization in the PTA-VSD group was greater (P = 0.002, <0.05), but no significant difference in hospitalization frequency and cost was observed between the 2 groups. During follow-up, there was 1 death and 1 amputation in the PTA-UD group, but no death or amputation in the PTA-VSD group. Arterial occlusion was primarily located in the femoral-popliteal artery and the inferior knee artery in the 2 groups, and PTA intervention effectively opened the outflow tract of the affected limb. Two to three outflow tracts were opened in 41 patients. The ankle-brachial index (ABI) after surgery was significantly higher in both groups than before. Univariate and multivariate logistic regression analyses revealed that the Wagner grade and number of outflow channels and therapies (PTA-VSD) could be independent factors affecting ulcer healing. CONCLUSIONS The severity of DF ulcers is an important factor affecting the quality of life of patients. A multidisciplinary "one-stop" treatment strategy based on percutaneous endovascular angioplasty combined with negative pressure-sealing drainage can rapidly and effectively restore the blood flow to the affected limb and promote ulcer healing without increasing medical costs.
