RESUMO

OBJECTIVES: Few experiences on vertebrobasilar occlusion over underlying intracranial atherosclerotic disease have been reported in literature and the optimal strategy on how to perform a mechanical thrombectomy is unclear. The aim of this paper is to bring our experience based on patients admitted with acute vertebrobasilar occlusion with underlying atheromatous lesions. MATERIALS AND METHODS: Several data were collected from August 2009 to October 2022 including clinical history, pre- and post-treatment neurological objectivity, diagnostic images and angiographic procedural images, and clinical outcome at 6 months. We selected 13 patients from August 2009 to October 2022, 12 men and 1 woman, aged 40 to 82 years (mean age, 62.6 years). RESULTS: Mechanical thrombectomy with a thromboaspiration was performed in all patients as beginning of the procedure. In three patients, the procedures resulted in excellent angiographic result and clinical outcome, while in three patients, we observed a failure of the procedural and clinical outcome. For residual intracranial stenosis in three patients, an angioplasty was performed obtaining an ischemic area related to the posterior circulation. In four patients, a stent was placed, in three patients, we obtained a good clinical outcome with a mRS between 0 and 2, while one treatment resulted in death, probably due to a late endovascular treatment. CONCLUSIONS: Endovascular treatment with stent deployment appears to result in an excellent outcome in patients with occlusion of the vertebrobasilar circulation in cases of occlusion on atheromatic plaque. The degree of residual stenosis after thrombospiration can significantly affect subsequent type of treatment.

RESUMO

OBJECTIVE: Our study aimed to evaluate safety, efficacy and clinical outcomes in patients with acute ischemic stroke with occlusion of M2 segment treated with thromboaspiration. MATERIALS AND METHODS: A retrospective study was conducted in patients with ischemic stroke of M2 segment undergoing endovascular thromboaspiration. The time period analyzed was from October 2015 until February 2021. Thromboaspiration was performed with AXS Catalyst 5 (Stryker) or AXS Catalyst 6 (Stryker) catheters. The following parameters were assessed: risk factors for ischemic stroke, National Institutes of Health Stroke Scale (entry and discharge), pre-procedural fibrinolysis, pre-procedural and 24-h Alberta Stroke Program Early CT Score, recanalization time, number of passages for recanalization, Thrombolysis in cerebral infarction scale score, periprocedural complications, Modified Rankin Scale score at 90 days from procedure and mortality. RESULTS: 90 patients were included in the study. The mean age was 75 ± 11.1 with National Institutes of Health Stroke Scale at entry 13 ± 5 and 8 ± 4 at discharge. Pre-procedural fibrinolysis were performed in 40 patients. Pre-procedural Alberta Stroke Program Early CT Score were 8.8 ± 1.3 and 6.9 ± 2.4 after 24 h from the procedure. Time of recanalization from onset of symptoms was 300 ± 82 min. Number of passages for recanalization were 1.8 ± 1.1. Thrombolysis in cerebral infarction scale score ≥ 2b were obtained in 90 % of procedures. After 90 days 33 % of patient obtained an Modified Rankin Scale between 0 and 1 (between 0 and 2 was 40 %). We didn't detect any complication in 64 % of cases (subarachnoid haemorrhage in 2 %, HI1 and HI 2 in 15 %, PH1 in 9 % of patients, PH2 in 6 % of patients). CONCLUSIONS: This paper confirms the usefulness and safety of thrombospiration in patients with ischemic stroke in the M2 segment with low intra-operative risks, high technical success and positive impact on the outcome of the patients.

RESUMO

PURPOSE: To analyze the feasibility and effectiveness of the use of an intravascular ultrasound (IVUS)-guided re-entry catheter (IGRC) for femoropopliteal chronic total occlusions (FP-CTOs) after a failed anterograde approach compared with the bidirectional approach without the IGRC. MATERIALS AND METHODS: Between June 2019 and December 2022, an IGRC (Pioneer Plus; Philips Volcano, San Diego, California) was used in 52 patients after failure of conventional recanalization techniques (Group A). In the same period, 48 patients who were also eligible for IGRC use were treated without IGRC using the bidirectional approach (Group B). In Groups A and B, 12 (23.1%) and 3 (6.2%) patients experienced claudication, and 40 (76.9%) and 45 (93.7%) patients experienced critical limb-threatening ischemia, respectively. Clinical and procedural records, angiographic imaging findings, and follow-up data were collected, analyzed, and reviewed. RESULTS: Technical success was achieved in 49 (94.2%) patients in Group A and 44 (91.7%) patients in Group B (P = .616). Use of the IGRC was associated with a reduction of procedural time (120 vs 133 minutes; P < .001), radiation exposure (47 vs 59 Gy cm2; P < .001), iodinated contrast medium use (98 vs 138 mL; P = .028), and intraprocedural discomfort (numerical rating scale score, 4 vs 6; P < .001). CONCLUSIONS: Use of the IGRC was equivalently successful for FP-CTO recanalization compared with the use of the bidirectional approach, but it reduced radiation exposure, iodinated contrast medium used, patient discomfort, and procedural time. These advantages suggest that IGRC could be favored as the next-choice option for FP-CTOs after failure of anterograde recanalization.

RESUMO

We describe a case of a 65-year-old woman affected by hemangiopericytoma/solitary fibrous tumor of the right shoulder-subclavian region. Hemangiopericytoma/solitary fibrous tumor is a rare tumor of uncertain malignancy. She reports shoulder pain and inability to abduct the arm and elevate the shoulder. Imaging showed erosion of the scapula. The patient underwent 5 sessions of "on demand" embolization in the previous 2 years scheduled for recurrence of symptoms-swelling of tissues. Further 2 treatments were achieved through embolization via 2 different microballoon catheter combined with percutaneous cryoablation with 5 probes. Images after the treatment demonstrate a marked reduction in the hypervascularized area and an increase in the necrosis area. So, this combined treatment is safety and reproducible also in extrahepatic tissue.

RESUMO

BACKGROUND: CT perfusion (CTP) is used in patients with anterior circulation acute ischemic stroke (AIS) for predicting the final infarct volume (FIV). Tandem occlusion (TO), involving both intracranial large vessels and the ipsilateral cervical internal carotid artery could generate hemodynamic changes altering perfusion parameters. Our aim is to evaluate the accuracy of CTP in the prediction of the FIV in TOs. METHODS: consecutive patients with AIS due to middle cerebral artery occlusion, referred to a tertiary stroke center between March 2019 and January 2021, with an automated CTP and successful recanalization (mTICI = 2b - 3) after endovascular treatment were retrospectively included in the tandem group (TG) or in the control group (CG). Patients with parenchymal hematoma type 2, according to ECASS II classification of hemorrhagic transformations, were excluded in a secondary analysis. Demographic, clinical, radiological, time intervals, safety, and outcome measures were collected. RESULTS: among 319 patients analyzed, a comparison between the TG (N = 22) and CG (n = 37) revealed similar cerebral blood flow (CBF) > 30% (29.50 ± 32.33 vs. 15.76 ± 20.93 p = 0.18) and FIV (54.67 ± 65.73 vs. 55.14 ± 64.64 p = 0.875). Predicted ischemic core (PIC) and FIV correlated in both TG (tau = 0.761, p < 0.001) and CG (tau = 0.315, p = 0.029). The Bland-Altmann plot showed agreement between PIC and FIV for both groups, mainly in the secondary analysis. CONCLUSION: automated CTP could represent a good predictor of FIV in patients with AIS due to TO.

RESUMO

PURPOSE: The management of tandem extracranial internal carotid artery and intracranial large vessel occlusion during endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) has been under-investigated. We sought to investigate outcomes of AIS patients with tandem occlusion (TO) treated with carotid artery stenting (CAS) compared to those not treated with CAS (no-CAS) during EVT. METHODS: We performed a cohort study using data from AIS patients enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke. Outcomes were 3 months' mortality, functional outcome, complete and successful recanalization, any intracranial hemorrhage, parenchymal hematoma and symptomatic intracerebral hemorrhage. RESULTS: Among 466 AIS patients with TO, CAS patients were 122 and no-CAS patients were 226 (118 excluded). After adjustment for unbalanced variables, CAS was associated with a lower rate of 3 months' mortality (OR 0.407, 95% CI 0.171-0.969, p = 0.042). After adjustment for pre-defined variables, CAS was associated with a lower rate of 3 months' mortality (aOR 0.430, 95% CI 0.187-0.989, p = 0.047) and a higher rate of complete recanalization (aOR 1.986, 95% CI 1.121-3.518, p = 0.019), successful recanalization (aOR 2.433, 95% CI 1.263-4.686, p = 0.008) and parenchymal hematoma (aOR 2.876, 95% CI 1.173-7.050, p = 0.021). CAS was associated with lower 3 months mortality (OR 0.373, 95% CI 0.141-0.982, p = 0.046) and higher rates of successful recanalization (OR 2.082, 95% CI 1.099-3.942, p = 0.024) after adjustment for variables associated with 3 months' mortality and successful recanalization, respectively. CONCLUSIONS: Among AIS patients with TO, CAS during EVT was associated with a higher rate of successful reperfusion and a lower rate of 3 months' mortality.

RESUMO

Hughes-Stovin syndrome (HSS) is a rare potentially fatal vasculitis supposedly belonging to the spectrum of Behçet disease without ocular involvement. HSS tends to play by a temporal pattern, starting with thrombosis and followed by formation of pulmonary aneurysms. Since its mortality can reach 25% of cases, early recognition and appropriate therapy represent the major clinical challenges. We describe a rare case of HSS successfully treated via multidisciplinary management by an endovascular approach and immunosuppressive therapy.

RESUMO

Aim: To evaluate the efficacy of intravascular ultrasound (IVUS) in transjugular intrahepatic portosystemic shunt (TIPS) revision associated with phlebography and invasive pressure measurement in patients with clinical or radiological signs of TIPS malfunction. Background: Four patients underwent TIPS revision between February and August 2021. Right internal jugular vein access was achieved under ultrasonographic guidance, a catheter was advanced to achieve the Inferior Vena Cava (IVC) and afterward the Portal vein through the TIPS. Once the Portal vein was achieved, a phlebography was performed, followed by invasive pressure measurement and IVUS exam over the guidewire. Based on the combination of phlebography, invasive pressure measurement, and IVUS evaluations, TIPS dysfunction was treated either with angioplasty or stent apposition. Case description: In all patients, we obtained the reduction of porto-systemic gradient. In three patients, angioplasty with a 10 mm diameter balloon catheter was performed. Anticoagulation therapy was added to one patient. In one patient, the Viatorr's proximal extremity in the suprahepatic vein wall was dislocated, so it was lengthened with a "Viabahn" covered stent. None of the patients developed hepatic encephalopathy after both TIPS placement and TIPS revision. No complications related to the procedure were observed during the follow-up. Clinical improvement in the immediate follow-up period was observed in all patients. In two patients, the abdominal ascites resolved. In another one, the abdominal pain disappeared, and a reduction of the longitudinal spleen diameter was recorded at 3 months follow-up. Conclusion: The use of IVUS allowed us to correctly visualize the organic cause of TIPS malfunction and to obtain direct visualization of the results of endovascular treatment.

RESUMO

OBJECTIVES: To investigate the outcomes of patients with calcific lesions in the common femoral artery undergoing endovascular procedures with atherectomy device and scoring balloon angioplasty combined with treatment of steno-occlusive disease of the remaining arterial districts of the lower limb. METHODS: Between January 2015 and December 2018, 11 diabetic patients at high risk for "major amputation", with calcific lesions of the common femoral artery and ischemic ulcers requiring endovascular treatment were retrospectively evaluated. Technical success was defined as revascularization of the common femoral artery with a residual stenosis lower than 30%. Primary endpoints were an immediate increase of perilesional transcutaneous oxygen pressure (TCPO2) > 40 mmHg, ulcerative lesions improvement up to healing or skin flaps re-epithelialization after minor amputation, limb rescue with rejected major amputation, and resolution of rest pain if present. RESULTS: The success rate of the revascularization procedures was 100%. No patient underwent surgical conversion. One case of peri-operative bleeding at the brachial access site was observed. There were no cases of arterial dissection or undesired distal embolization. The average baseline value of perilesional TCPO2 was 21.8 ± 9.2 mmHg. The mean TCPO2 value was 57.4 ± 7.2 mmHg three days after the procedure (P < 0.05), and 51.2 ± 9.8 mmHg 15 days after (P < 0.05). Minor amputations were performed in five patients with advanced ulcerative lesions. No major amputations were performed in the follow-up period. At 14 months follow-up, one patient developed new occlusion of the CFA for extension from the external iliac artery and underwent a new endovascular procedure. We observed an overall primary patency rate of 91% and a primary assisted patency rate of 100% in our 18-month follow-up. CONCLUSIONS: Endovascular approach for severely calcified atherosclerotic lesions of the common femoral artery seems to represent a valid therapeutic option associated with promising results in terms of clinical outcome and low complication rates.

RESUMO

BACKGROUND: The Careggi Collateral Score (CCS) (qualitative-quantitative evaluation) was developed from a single-centre cohort as an angiographic score to describe both the extension and effectiveness of the pial collateral circulation in stroke patients with occlusion of the anterior circulation. We aimed to examine the association between CCS (quantitative evaluation) and 3-month modified Rankin Scale (mRS) score in a large multi-center cohort of patients receiving thrombectomy for stroke with occlusion of middle cerebral artery (MCA). METHODS: We conducted a study on prospectively collected data from 1284 patients enrolled in the Italian Registry of Endovascular Treatment in Acute Stroke. According to the extension of the retrograde reperfusion in the cortical anterior cerebral artery (ACA)-MCA territories, CCS ranges from 0 (absence of retrograde filling) to 4 (visualization of collaterals until the alar segment of the MCA). RESULTS: Using CCS of 4 as reference, CCS grades were associated in the direction of unfavourable outcome on 3-month mRS shift (0 to 6); significant difference was found between CCS of 0 and CCS of 1 and between CCS of 3 and CCS of 4. CCS ≥ 3 was the optimal cut-off for predicting 3-month excellent outcome, while CCS ≥ 1 was the optimal cut-off for predicting 3-month survival. CCS of 0 and CCS < 3 were associated in the direction of unfavourable recanalization on TICI shift (0 to 3) compared with CCS ≥ 1 and CCS ≥ 3, respectively. Compared with CCS ≥ 3 as reference, CCS of 0 and CCS 1 to 2 were associated in the direction of unfavourable recanalization on TICI shift. There was no evidence of heterogeneity of effects of successful recanalization and procedure time ≤ 60 min on 3-month mRS shift across CCS categories. CONCLUSION: The CCS could provide a future advantage for improving the prognosis in patients receiving thrombectomy for stroke with M1 or M1-M2 segment of the MCA occlusion.

RESUMO

The study aims to evaluate the effectiveness of foot revascularization in persons with diabetic foot ulcers (DFUs) and below-the-ankle (BTA) arterial disease. Consecutive patients referred for a new active ischaemic DFU requiring lower limb revascularization were considered. Among those, only patients with a BTA arterial disease were included. Revascularization procedures were retrospectively analysed: in the case of successful foot revascularization (recanalization of pedal artery, or plantar arteries or both) or not, patients were respectively divided in two groups, successful foot perfusion (SFP) and failed foot perfusion (FFP). Healing, minor and major amputation at 12 months of follow-up were evaluated and compared. Eighty patients (80) were included. The mean age was 70.5 ± 10.9 years, 55 (68.7%) were male, 72 (90%) were affected by type 2 diabetes with a mean duration of 22.7 ± 11.3 years. Overall 45 (56.2%) patients healed, 47 (58.7%) had minor amputation and 13 (16.2%) major amputation. Outcomes for SFP and FFP were respectively: healing (89.3 vs. 9.1%, p < 0.0001), minor amputation (44.7 vs. 78.8%, p = 0.0001), major amputation (2.1 vs. 36.3%, p < 0.0001). Failed foot revascularization resulted an independent predictor of non-healing, minor amputation, and major amputation. Foot revascularization is mandatory to achieve healing and avoid major amputation in persons with ischaemic DFU and BTA arterial disease.

RESUMO

OBJECTIVE: To describe the angiographic characteristics of peripheral arterial disease (PAD) in persons with diabetic foot ulcers (DFUs) on dialysis treatment. METHOD: The study is a retrospective analysis of patients with DFUs and PAD who had been referred to our diabetic foot clinic. All patients had been managed by a pre-set limb salvage protocol including revascularisation of the affected limb. Arterial lesions (stenosis between 50-99% and occlusions) were retrospectively evaluated through angiogram analysis. According to the presence or not of dialysis, patients were divided into two patient groups: renal-diabetic foot (RDF) and diabetic foot (DF). Distribution of PAD and immediate revascularisation outcome (technical revascularisation outcome) for RDF and DF were separately reported and compared. RESULTS: The sample included 239 patients: mean age was 71.8 years; 72.4% were male; 87.4% had type 2 diabetes; mean diabetes duration was 21.4 years; and the mean HbA1c was 63±22mmol/mol. The RDF group compared with the DF group reported higher numbers of vessels affected (n=5±1.6 versus 3.9±1.5, respectively, p<0.0001), greater involvement of the superficial femoral artery (90.2% versus 75.8%, respectively, p=0.003), the tibial-peroneal trunk (53.7% versus 25.5%, respectively, p=0.01), the anterior tibial artery (93.9% versus 80.9%, respectively, p=0.03) and below-the-ankle (BTA) arteries (70.7% versus 35.7%, respectively, p=0.0001). The RDF group showed a higher rate of revascularisation failure in comparison to DF patients (43.9% versus 15.3%, respectively, p<0.0001). BTA arterial disease (odds ratio 9.5; 95% Confidence Interval: 3.5-25.4; p=0.0001) resulted as the only independent predictor of revascularisation failure. CONCLUSION: In this study, RDF patients showed a widespread distribution of arterial lesions with a higher involvement of foot arteries in comparison with DF patients. BTA arterial disease was found to be an independent predictor of revascularisation failure.

RESUMO

In this paper, we describe a rare case of coronary artery aneurysms occasionally found on a pre interventional Coronary Computed Tomography Angiography performed on a 67-year-old man with a history of aneurysm of the ascending aorta previously treated with Bentall surgery, who arrived at our hospital to have a percutaneous valve-in-valve implantation procedure. Even though the patient was considered not eligible for the procedure, due to his many comorbidities, and conservatively managed, at 1-year followup his angiographic condition remained stable.

RESUMO

ABSTRACT: To investigate the relationship between damaged lung assessed by chest computed tomography (CT) scan and laboratory biochemical parameters with the aim of finding other diagnostic tools.Patients who underwent chest CT for suspected Corona Virus Disease-2019 (COVID-19) pneumonia at the emergency department admission in the first phase of COVID-19 epidemic in Italy were retrospectively analyzed. Patients with both negative chest CT and absence of the novel coronavirus in nasopharyngeal or oropharyngeal real-time reverse transcriptase polymerase chain reaction (RT-PCR) swabs were excluded from the study. A total of 462 patients with positive CT scans for interstitial pneumonia were included in the study (250 males and 212 females, mean age 57 ±â€Š17 years, range 18-89). Of these, 344 were positive to RT-PCR test, 118 were negative to double RT-PCR tests.CTs were analyzed for quantification of affected lung volume visually and by dedicated software. Statistical analysis to evaluate the relationship between laboratory analyses and CT patterns and amount of damaged lung related with COVID-19 pneumonia was performed in 2 groups of patients: positive RT-PCR COVID-19 group and negative RT-PCR COVID-19 group, but both with positive CT scans for interstitial pneumonia.Lymphocytopenia, C-reactive protein (CRP), lactate dehydrogenase (LDH), d-dimer, and fibrinogen increased levels occurred in most patients without statistically significant differences between the 2 groups with CT scans suggestive for COVID-19. In fact, in both groups the volume of lung damage was strongly associated with altered laboratory test results, even for patients with negative RT-PCR test.The decreased number of lymphocytes, and the increased levels of CRP, LDH, d-dimer, and fibrinogen levels are associated with SARS-CoV 2 related pneumonia. This may be useful as an additional diagnostic tool in patients with double negative RT-PCR assay and with highly suspected clinic and chest CT features for COVID-19 to isolate patients in a pandemic period.

RESUMO

A 39-year-old female, liver transplanted for Autosomic Dominant Polycystic Kidney Disease (ADPKD) developed refractory ascites early after surgery, with frequent need of large-volume paracentesis. This was associated with severe sarcopenia and kidney impairment. Liver biopsy showed a sinusoidal congestion with a significant enlargement of hepatic portal veins. This picture suggested the diagnosis of vascular obstructions. Due to an unfavorable passage through the piggy-back surgical anastomosis and the angle between the hepatic veins and the portal branches, a conventional placement of a transjugular portosystemic shunt (TIPS) was not feasible. An alternative approach was pursued with success, using a combined percutaneous-transjugular approach and achieving a complete recovery of ascites, sarcopenia and renal function.

RESUMO

PURPOSE: Intracranial carotid artery occlusion represents an underinvestigated cause of acute ischemic stroke as well as an indication for mechanical thrombectomy. We investigated baseline and procedural characteristics, outcomes and predictors of outcome in patients with acute ischemic stroke secondary to intracranial carotid artery occlusion. METHODS: A retrospective analysis of the Italian Registry of Endovascular Treatment in Acute Stroke was performed. Patients with intracranial carotid artery occlusion (infraclinoid and supraclinoid) with or without cervical artery occlusion but with patent intracranial arteries were included. The 3­month functional independence, mortality, successful reperfusion and symptomatic intracranial hemorrhage were evaluated. RESULTS: Intracranial carotid artery occlusion with patent intracranial arteries was diagnosed in 387 out of 4940 (7.8%) patients. The median age was 74 years and median baseline National Institute of Health Stroke Scale (NIHSS) was 18. Functional independence was achieved in 130 (34%) patients, successful reperfusion in 289 (75%) and symptomatic intracranial hemorrhage in 33 (9%), whereas mortality occurred in 111 (29%) patients. In univariate analysis functional independence was associated with lower age, lower NIHSS at presentation, higher rate of successful reperfusion and lower rate of symptomatic intracranial hemorrhage. Multivariable regression analysis found age (odds ratio, OR:1.03; P = 0.006), NIHSS at presentation (OR: 1.07; P < 0.001), diabetes (OR: 2.60; P = 0.002), successful reperfusion (OR:0.20; P < 0.001) and symptomatic intracranial hemorrhage (OR: 4.17; P < 0.001) as the best independent predictors of outcome. CONCLUSION: Our study showed a not negligible rate of intracranial carotid artery occlusion with patent intracranial arteries, presenting mostly as severe stroke, with an acceptable rate of 3­month functional independence. Age, NIHSS at presentation and successful reperfusion were the best independent predictors of outcome.

RESUMO

The study aimed to evaluate clinical and vascular characteristics, as well as outcomes, for diabetic persons with foot ulceration and no-option critical limb ischemia (CLI). The study group included a sample of patients admitted to our diabetic foot unit because of a new diabetic foot ulcer and CLI. All subjects were managed using a limb salvage protocol which includes lower-limb revascularization. According to whether or not the revascularization procedure was a success, patients were respectively divided into two groups: successfully treated CLI patients (ST-CLI) and no-option CLI patients (NO-CLI). Failed revascularization was considered in the case of technical recanalization failure of occluded vessels (inability to overcome the obstruction) and/or absence of arterial flow to the foot. Limb salvage, major amputation, and death after 1 year of follow-up were evaluated and compared between the two groups. Overall, 239 patients were included, 74.9% belonging to ST-CLI and 25.1% to NO-CLI. NO-CLI patients reported more cases of ischemic heart disease (80 vs. 62.1, p = 0.008), heart failure (63.3 vs. 32.4%, p < 0.0001), and end-stage renal disease (ESRD) (60 vs. 25.7%) than ST-CLI patients. In addition, more vessels were affected in the NO-CLI group (5.2 ± 1.6 vs. 4 ± 1.5, p < 0.0001), and there was more involvement of tibio-peroneal trunk (50 vs. 30.2%, p = 0.006), anterior tibial (93.3 vs. 82.7, p = 0.03), posterior tibial (93.3 vs. 73.7%, p = 0.0005), peroneal (70 vs. 48%, p = 0.002), and below-the-ankle arteries (73.3 vs. 39.1%, p < 0.0001) than ST-CLI. The 1 year outcomes for the whole population were 69.9% limb salvage, 10.9% major amputation, and 19.2% death. The outcomes for NO-CLI and ST-CLI were, respectively, as follows: limb salvage (13.8 vs. 73.4%, p < 0.0001), amputation (30 vs. 4.5%, p = 0.0001), and mortality (50 vs. 8.9%, p < 0.0001). NO-CLI patients showed a more severe pattern of peripheral arterial disease (PAD) with distal arterial lesions and worse outcomes than ST-CLI.
