Imaging Evaluation and Endovascular Treatment of Vasospasm

Persistent sciatic artery (PSA) is an embryologic remnant of the internal iliac artery, and when is present, it undergoes aneurysmal degeneration in up to 60% of the cases. Endovascular repair is an increasingly utilized treatment strategy for PSA aneurysms (PSAAs). The objective was to demonstrate the safety and efficacy of the endovascular repair in patients with PSAA and to identify potential risk factors for loss of patency or limb loss. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and eligible studies were identified through search of the PubMed, Scopus, and Cochrane Central databases. Fifteen case reports, comprising 15 patients overall, were included. The median age of the patients was 68 years old (mean age 66 ± 13.4 years) with half of the reported patients being women. Most patients presented with progressive limb claudication, complaining about an enlarging palpable pulsatile buttock mass. The onset of symptoms was sudden in 78% of the reported cases. Additionally, the distal pulses on PSAA side were diminished or absent in 91% of the patients. Acute limb ischemia was the primary diagnosis in 75% of the cases. All patients underwent endovascular repair of the PSAA with a covered stent. Procedural outcomes were favorable in all patients demonstrating no symptoms recurrence, aneurysmal regression, or total obliteration evaluated by angiographic studies (computed tomography angiography [CTA] and angiogram). Periprocedural imaging evaluation was determined either with CTA or duplex ultrasound (DUS). Periprocedural complications included only 1 endoleak with distal dissection. This endoleak was identified after stent deployment and dissection distal to the aneurysm. Mean follow-up (with CTA and/or DUS) was 22 months, with all patients being asymptomatic with no recurrence of symptom. The endovascular treatment of PSAA with covered stent is safe and effective. Persistent sciatic artery aneurysms is associated with high procedural success, low periprocedural compilations, and favorable mid-term follow-up.

The authors describe a 14-year-old boy presenting with an orbitocranial penetrating injury (OPI) from a metallic air gun pellet to the left eye who developed hemiparesis and speech difficulty due to migration of the pellet to the left middle cerebral artery. They highlight the potential complications associated with both OPIs and intravascular foreign body migration and occlusion by describing the patient’s presentation, results of imaging evaluation, and the combined endovascular treatment and extracranial-intracranial bypass, which resulted in rapid restoration of blood flow and full neurological recovery with intact vision. Based on this case and a review of the literature on intracranial foreign body migration with resultant vascular occlusion, the authors recommend that complex OPIs be treated at centers that offer both neuroendovascular and neurovascular surgical capabilities on an urgent basis to manage both the primary injury and potential secondary vascular compromise.

BackgroundThe endovascular treatment (ET) for acute ischemic stroke is increasing among eligible patients. Assessing patients’ perspectives on quality of life (QOL) can supplement the use of formal outcome scales and enable the assessment of outcomes across multiple domains affected by stroke.MethodsWe analyzed publicly available data from the Endovascular Therapy Following Imaging Evaluation for Ischemic Stroke (DEFUSE 3) trial. We evaluated patients who survived beyond the time of discharge from their acute hospitalizations and completed all Neuro-QOL short forms at 90-day follow-up.ResultsOur final analysis included 128 patients (median age 67 [range 23–90] years, 50.8% men). As modified Rankin Scale (mRS) scores increased, there was a consistent increase in the severity of Neuro-QOL measures. T-scores for mobility, cognitive function, and the ability to participate in social roles declined significantly while depression T-scores increased significantly. We found that QOL T-scores for patients with mRS 3 did not differ significantly from T-scores for patients with mRS 2 in any domain.ConclusionsAmong ischemic stroke patients eligible for ET, QOL scores help validate and supplement quantitatively measured outcomes.

Risk Of Rupture

Abdominal aortic aneurysm (AAA) is a potentially fatal condition with risk of rupture increasing as maximum AAA diameter increases. It is agreed upon that open surgical or endovascular treatment is indicated if maximum AAA diameter exceeds 5 to 5.5cm. Continuing aneurysmal degeneration of aortoiliac arteries accounts for significant morbidity, especially in patients undergoing endovascular AAA repair. Purpose of this review is to give an overview of the current evidence of medical treatment of AAA and describe prospects of potential pharmacological approaches towards prevention of aneurysmal degeneration of small AAAs and to highlight possible adjunctive medical treatment approaches after open surgical or endovascular AAA therapy.

Summary. Background: To assess the impact of short- vs. long-term anticoagulation in addition to standard dual antiplatelet therapy (DAPT) upon endovascular treatment of (sub)acute thrombembolic occlusions of the lower extremity. Patient and methods: Retrospective analysis was conducted on 202 patients with a thrombembolic occlusion of lower extremities, followed by crirical limb ischemia that received endovascular treatment including thrombolysis, mechanical thrombectomy, or a combination of both between 2006 and 2015 at a single center. Following antithrombotic regimes were compared: 1) dual antiplatelet therapy, DAPT for 4 weeks (aspirin 100 mg/d and clopidogrel 75 mg/d) upon intervention, followed by a lifelong single antiplatelet therapy; 2) DAPT plus short term anticoagulation for 4 weeks, followed by a lifelong single antiplatelet therapy; 3) DAPT plus long term anticoagulation for > 4 weeks, followed by a lifelong anticoagulation. Results: Endovascular treatment was associated with high immediate revascularization (> 98 %), as well as overall and amputation-free survival rates (> 85 %), independent from the chosen anticoagulation regime in a two-year follow up, p > 0.05. Anticoagulation in addition to standard antiplatelet therapy had no significant effect on patency or freedom from target lesion revascularization (TLR) 24 months upon index procedure for both thrombotic and embolic occlusions. Severe bleeding complications occurred more often in the long-term anticoagulation group (9.3 % vs. 5.6 % (short-term group) and 6.5 % (DAPT group), p > 0.05). Conclusions: Our observational study demonstrates that the choice of an antithrombotic regime had no impact on the long-term follow-up after endovascular treatment of acute thrombembolic limb ischemia whereas prolonged anticoagulation was associated with a nominal increase in severe bleeding complications.

Risk Of Rupture

Abstract. This article analyses if and to what extent gender differences exist in abdominal aortic aneurysm (AAA) therapy. For this purpose Medline (PubMed) was searched from January 1999 to January 2018. Keywords were: “abdominal aortic aneurysm”, “gender”, “prevalence”, “EVAR”, and “open surgery of abdominal aortic aneurysm”. Regardless of open or endovascular treatment of abdominal aortic aneurysms, women have a higher rate of complications and longer hospitalizations compared to men. The majority of studies showed that women have a lower survival rate for surgical and endovascular treatment of abdominal aneurysms after both elective and emergency interventions. Women receive less surgical/interventional and protective medical treatment. Women seem to have a higher risk of rupture, a lower survival rate in AAA, and a higher rate of complications, regardless of endovascular or open treatment. The gender differences may be due to a higher age of women at diagnosis and therapy associated with higher comorbidity, but also because of genetic, hormonal, anatomical, biological, and socio-cultural differences. Strategies for treatment in female patients must be further defined to optimize outcome.

Hybrid Treatment

Abstract. Background: Endovascular treatment is an alternative first-line management for peripheral artery disease (PAD). Hybrid treatment (HT) is defined as a combined treatment for patients with PAD using endovascular and open surgery, simultaneously performed in an operating room. The results of HT are reportedly good for multilevel revascularization (MR) in patients with chronic limb ischaemia, and even in older high-risk patients. The goal of this study was to examine the clinical and haemodynamic outcomes of HT in patients who need MR. Patients and methods: Nine university hospitals in Korea participated in this multicentre study. A total of 134 patients with multilevel PAD underwent HT and MR. Patients were enrolled from July 2014 to June 2015 and were followed for 18 months. Results: The mean age of the patients was 68.8 ± 9.93 years and 88.1 % were men. Patients with Rutherford category 2 to 3 and 4 to 6 comprised 59.0 % and 42.0 % of the group, respectively. The technical success rate was 100 %. The primary patency rates at 12 and 18 months were 77.6 % and 63.9 %, respectively. The primary-assisted patency rates at 12 and 18 months were both 90.0 %. The pre-operative mean ankle brachial index (0.43 ± 0.23) increased to 0.87 ± 0.23 at six months post-operatively (t-test, p < 0.05). The amputation free survival rate was 97.1 %. Conclusions: Although outcomes of multilevel PAD are reportedly poor when endovascular treatment alone is used, we have shown that HT is a feasible alternative modality for patients with multilevel PAD, with satisfactory amputation-free survival and freedom from re-intervention rates.

Artery Disease

Background: Peripheral artery disease (PAD) affecting the femoropopliteal artery is treated by endovascular interventions [2, 5, 13] increasingly. Aim of the study was to evaluate mid-term efficacy and patency of long stents in the superficial femoral and popliteal artery. Patients and methods: Between September 2006 and September 2007 103 patients received 128 stents for endovascular treatment of femoropopliteal vascular stenosis or occlusion. Clinical and hemodynamic parameters were collected. Risk factors, popliteal involvement and TASC classification, were documented and evaluated. Results: Immediate outcome was satisfactory with a technical success rate of 100 %. After a mean follow-up period of 21 months, primary patency was 83.6 %. Potential risk factor analysis for restenosis and fracture demonstrated hypertension to have borderline significance (P = 0.06). In normotensive patients no restenosis occurred. Further pre-conditions, e.g. smoking, metabolic syndrome, age, gender and previous intervention did not show any influence on restenosis or stent fracture. TASC C and D lesion had similar patency rates compared to TASC A and B lesions. Most of the restenoses (13 out of 16) were observed within the first six months of follow-up. Six stent fracture were observed (4.7 %). Conclusions: Long stents had convincing results after endovascular treatment of the femoropopliteal PAD. The used stent was an efficacious endovascular tool for long athersclerotic lesions in the superficial femoral and popliteal artery. Fracture rate was low with an incidence of 4.7 %. Most restenoses occurred within the first six months so that careful follow-up would be necessary.
