Purpose: To evaluate the safety and performance of ultrasound-enhanced thrombolysis in the treatment of acute thrombotic or embolic occlusion of the lower limb arteries. Methods: From April 2005 to July 2006, 25 patients (15 men; mean age 64.1 years, range 37–82) presenting with acute (<14 days old) occlusions of the lower limb arteries were treated with local thrombolysis [recombinant tissue plasminogen activator (rtPA)] in a dosage of 1.0 mg/h using the EKOS Lysus Peripheral Catheter System with an ultrasound core. No bolus injection of rtPA was given. The mean occlusion length was 25.1 cm (range 2–70). Results: The technical success rate was 100%. Total clot removal was achieved in 22 (88%) patients after 16.9 hours (range 5–24) using a mean 17 mg (range 5–25) of rtPA. In 8 cases, total clot removal of the main lesion was achieved after 6 hours (6 mg of rtPA). In 1 patient, lysis was stopped after 2.5 hours because of bleeding due a dislocation of the introducer sheath. In 2 cases, total clot removal could not be achieved; these patients were successfully treated with thromboaspiration. At the 1-month follow-up, the treated vessel was still patent in 20 patients. Two reocclusions occurred; 1 was treated with a bypass graft and the other with conservative therapy. There were no cases of amputation or death during follow-up. There were no side effects related to rtPA or the catheter system. Conclusion: This study demonstrates that local lysis of acute arterial occlusions using the Lysus Peripheral Catheter System is safe and effective. Blood flow is restored quickly.

Objectives In this study, perioperative properties and early outcomes of patients who underwent combined Temren rotational atherectomy (RA) and drug-coated balloon (DCB) angioplasty treatment for complex femoropopliteal lesions in a single center were reported. Methods Between June 2019 and February 2020, 40 patients who underwent combined Temren RA and DCB treatment due to critical lower limb ischemia or claudication-limiting daily living activities were retrospectively evaluated. Results The mean age of patients was 73.2 ± 7.8 years and the majority of the patients were male (65%). Of the patients, 17 had critical limb ischemia and 23 had lifestyle-limiting claudication. Pathologies were total occlusion in 33 limbs and critical stenosis in seven limbs. Nine patients previously underwent endovascular intervention or surgery. The mean total occlusion length was 140.9 ± 100.9 (range, 20–360) mm in patients with chronic total occlusion. There was an additional iliac artery pathology in 5 and below the knee pathology in 8 patients. Rotational atherectomy was possible in all cases. Flow-limiting dissection was seen in six patients (15%). Provisional stent was performed to these patients. Following Temren RA, all patients underwent DCB. Adequate vascular lumen (less than 30% stenosis) was provided in all patients and the symptoms regressed. No distal embolization was encountered. Access site complications (17.5%) were small hematoma in four patients, ecchymosis in two patients, and pseudoaneurysm of the femoral artery in one patient. The mean follow-up was 13.55 ± 4.2 (range, 1–18) months. Re-occlusion was seen in three patients (7.5%) ( n = 2 at 2 months and n = 1 at 4 months). Of these patients, two had required open revascularization via femoropopliteal bypass graft with common, superficial femoral, and popliteal artery endarterectomy and one had required femoro-posterior tibial artery bypass. Four minor toe amputations (10%) were performed to reach complete wound healing in the critical limb ischemia patients. A below-knee amputation was performed in a 94-year-old patient with long segment stenosis at the end of a 1-month follow-up period. There was no mortality after follow-ups. The Kaplan–Meier estimator estimated the rate of freedom from target lesion revascularization (TLR) which was 92.3%. The decrease in the Rutherford levels after the procedure was found to be statistically significant in 36 patients ( p < 0.001). The increase in the ankle–brachial index after the procedure was found to be statistically significant in 36 patients ( p < 0.001). Conclusions Combined use of Temren RA with adjunctive DCB is safe and effective method with high rates of primary patency and freedom from TLR and low rates of complication in the treatment of femoropopliteal lesions.

Purpose: To report an alternative approach for rescue of an occluded aortofemoral bypass using the Gore Excluder Iliac Branch Endoprosthesis (IBE). Case Report: A 52-year-old man presented with acute right limb ischemia because of displaced and occluded iliac stents and was treated with aortofemoral bypass. On the third postoperative day, there was early bypass failure due to distal embolization from aortic thrombus. After fluoroscopy-guided balloon thrombectomy of the bypass, an endovascular bailout strategy was used. The Gore Excluder IBE was deployed below the renal arteries (with the external iliac limb opening in the surgical prosthesis and the gate opening within the aortic lumen). After antegrade catheterization of the gate, a Gore Viabahn endoprosthesis was inserted as the bridging endograft and deployed so that it landed just above the preimplanted aortoiliac kissing stents without overlapping them. Completion angiography showed technical success without complications; results were sustained at 1-year follow-up. Conclusion: The Gore Excluder IBE may represent a versatile solution for the rescue of complex cases when open surgery would be associated with a considerable risk. This off-label application of a well-recognized endovascular device is safe and feasible and may prove useful as a valuable alternative in properly selected patients.

Background. The treatment of chronic critical ischemia of the lower extremities with their combined atherodiabetic lesion is one of the far from the resolved problems of modern surgery. Aim of the study. Analysis of the results of X-ray endovascular interventions in patients with critical lower limb ischemia due to atherodiabetic lesions of the femoral-popliteal-tibial segment. Material and methods. We analyzed the results of REVS in 60 patients with diabetes mellitus with critical ischemia of the lower extremities due to infra-anginal atherosclerotic occlusions with a follow-up period of up to 5 years from the moment of the manipulation. Results. The total shelf life of the lower limb after REVV was 492.4 ± 10.1 days. Out of 26 amputations performed, balloon angioplasty was performed in 18 cases and stenting in 8 cases. In individuals with type I diabetes, the duration of painless period was 415.4 ± 5.1 days, and the total shelf life of the leg was 465.4 ± 4.3 days. In type II diabetes, these indicators were, respectively, 181.4 ± 4.4 days and 317.8 ± 6.7 days. In the group of patients with type I diabetes, the lower limb was saved in 55.6% of cases (in 20 out of 36 patients), and in type II diabetes - in 58.3% (in 14 out of 24 people). Conclusions. The presence of simultaneously obliterating atherosclerosis and diabetes mellitus in patients leads to a combined atherodiabetic lesion of the arterial bed, including infra-anginal arteries. X-ray endovascular interventions (balloon angioplasty and stenting) on the arterial femoral-popliteal-tibial segment are a rather effective method of eliminating chronic critical lower limb ischemia, which allows preserving the lower limb in 56.7% patients with a follow-up period of up to 5 years from the date of surgery. Improving the results of X-ray endovascular interventions in case of chronic critical atherodiabetic lower limb ischemia requires a comprehensive study of the possible causes of occlusions of reconstructed arterial segments (blood coagulation potential, non-optimal processes in the intervention zone).

Introduction. Acute lower limb ischemia results from thrombosis or embolization of diseased native artery or previously implanted bypass graft. When this occurs, several options are available to restore blood flow: catheter-directed thrombolysis, mechanical thrombectomy or open surgery. Fundamental reasons to apply percutaneous interventions are avoiding open procedures in high risk patients, and avoiding difficult dissection through scar tissue. Case Outline. A 67-year-old male was admitted at our Institution for critical limb ischemia. After performed angiography the diagnosis of occluded femoropopliteal graft was established. Occlusion was resolved by catheter-directed thrombolysis with plasmin. Culprit lesions were treated by angioplasty. Conclusion. Our patient underwent a successful thrombolysis of occluded femoropopliteal graft with locally-delivered human plasmin.

Background: Catheter-directed intraarterial thrombolytic therapy with rt-PA has been established as an alternative to surgery in selected patients with lower limb ischemia. The purpose of this study is to evaluate its long-term results and to try to identify patient variables influencing outcome. Patients and methods: The results of thrombolytic treatment for acute or subacute lower limb ischemia in 82 patients (51 male, 31 female) were retrospectively analysed. Clinical data (time of symptoms onset, clinical stage, type of affected vessel, anatomical localisation) as well as comorbidities were recorded. The success rate of thrombolysis as well as the incidence of adverse events was evaluated. Patients with initial success were followed up after a median of 52,5 months. Results: Thrombolytic therapy was successful in 67 cases (82%). An additional endovascular or surgical procedure was necessary in 39 of these patients (48%). The overall bleeding rate was 18% and the mortality and major amputation rate was 1%. 42 patients with early clinical success were available for follow-up. 34 of them (81%) were free of ischemic symptoms and the overall limb salvage rate was 96%. We could not identify factors significantly influencing early or long-term results, although there was a trend towards better results in patients with acute ischemia and in patients with occluded native arteries. Conclusions: Intraarterial local thrombolytic therapy has a relatively high initial success rate in selected patients with lower limb ischemia, but is associated with a significant number of bleeding complications. Furthermore, additional procedures are required in almost half the patients. Initial success is durable at the long-term in the majority of cases. Better selection of patients and refinements of the thrombolytic therapy might help to further improve results and lower the bleeding complications.

Introduction: Acute limb ischemia is a critical medical condition that can quickly become a life threat. Therapeutic modalities such as catheter-directed thrombolysis (CDT) have demonstrated various levels of efficacy in previous studies. Objective: This study presents the descriptive findings of a series of cases who presented with acute arterial thrombotic limb ischemia and underwent CDT. Methods: This was a cross-sectional single-hospital-based case series, in which all patients who were diagnosed with acute arterial thrombotic limb ischemia, and consequently underwent CDT during the oneyear study period were included. Detailed baseline characteristics and clinical findings of the studied patients on presentation, after intervention and at one-year follow-up are presented. Results: A total of 21 patients with a mean age of 60.7±15.2 years, including 16 males (76.2%) were included. The initial technical and treatment success rates were 20 (95.2%) and 14 (66.7%), respectively. The amputation-free and the overall survival rates after the one-year follow-up were 15 (71.4%) and 17 (81%), respectively. Four patients (19%) developed complications, two (9.5%) of which were significant (pulmonary hemorrhage and intraventricular hemorrhage). Amputation was performed in 6 (28.6%) cases. Conclusion: In this study, the treatment success rate and the technical success rate were satisfactory.

The deep femoral artery (DFA) offers several advantages as an inflow vessel in lower-extremity bypasses. We report a single-center experience using the DFA as an inflow artery for lower-extremity revascularization. We reviewed all patients who underwent a lower-extremity bypass utilizing the DFA as the inflow vessel. Demographics, indications for surgery, indication for use of the DFA, type of conduits and target vessels were recorded. Follow-up data included resolution of symptoms, bypass graft patency, major amputations and survival. Over 2.5 years, 23 patients were treated with a DFA-inflow bypass. Eighteen (78%) suffered from wounds and five (22%) from rest pain. The proximal, middle and distal DFA was used in 8, 14 and 1 patients, respectively. Indications for using the DFA were limited vein conduit (16) and a hostile groin (5). All patients experienced initial resolution of their ischemic symptoms. The primary patency at two years was 93%. The survival rate was 83%. In conclusion, the DFA is an excellent and underutilized alternative inflow artery in patients requiring lower limb revascularization. It offers excellent patency rates and should be considered in patients with hostile groins or insufficient lengths of a vein conduit.

High-risk pulmonary embolism (PE) requires hemodynamic and respiratory support along with reperfusion strategies. Recently updated European guidelines assign a low class of recommendation to extracorporeal membrane oxygenation (ECMO) for high-risk PE. This systematic review assessed clinical outcomes after ECMO in high-risk PE. We searched electronic databases including PubMed, Embase and Web of Science from January 2000 to April 2020. Efficacy outcomes included in-hospital survival with good neurological outcome and survival at follow-up. Safety outcomes included lower limb ischemia and hemorrhagic and ischemic stroke. Where possible (absence of high heterogeneity), meta-analyses of outcomes were undertaken using a random-effects model. We included 16 uncontrolled case-series (533 participants). In-hospital survival with good neurological outcome ranged between 50% and 95% while overall survival at follow-up ranged from 35% to 95%, both with a major degree of heterogeneity (I2 > 70%). The prevalence of lower limb ischemia was 8% (95% CI 3% to 15%). The prevalence of stroke (either hemorrhagic or ischemic) was 11% (95% CI 3% to 23%), with notable heterogeneity (I² = 63.35%). Based on currently available literature, it is not possible to draw definite conclusions on the usefulness of ECMO for high-risk PE. Prospective, multicenter, large-scale studies or nationwide registries are needed to best define the role of ECMO for high-risk PE. PROSPERO registration ID: CRD42019136282.
