Endovascular Procedures

Endovascular Procedures: A comprehensive overview of minimally invasive surgical techniques used to treat conditions affecting blood vessels.
These procedures involve the insertion of catheters, stents, and other devices through small incisions to access and repair damaged or blocked arteries and veins.
Endovascular procedures offer reduced recovery time and risk compared to open surgey, making them a preferred option for many patients.
Researchers and clinicians can leverage AI-driven analysis tools, like PubCompare.ai, to streamline their endovascullar research and optimize patient outcomes.

A systematic search of English-language literature using MEDLINE, CINAHL, EMBASE, Cochrane, LLBA (Linguistics and Language Behaviour Abstract), Web of Science, Scopus and PsychINFO (January 1980 to May 2015) was performed along with a manual search of the cited references of the selected articles and the search cited features of PubMed. Appendix 1 lists the search strategy performed on MEDLINE as an example of the literature search performed in each database. The search was limited to comparative analyses between individuals who had a TBI and non-injured individuals (control). This study was not registered with PROSPERO.
The review includes studies assessing prosodic processing outcomes after the following procedures: traumatic brain injury, subdural hematomas, cerebral aneurysms, craniotomy (for glioma and meningioma), craniotomy for subdural hematoma, burr hole(s) for subdural hematoma, cerebral aneurysm repair by craniotomy and endovascular technique, ventriculoperitoneal shunt insertion and revision, endoscopic third ventriculostomy, surgical treatment of epilepsy, temporal lobectomy, amygdalohippocampectomy, hemispherectomy, callosotomy and other procedure for seizures, or other neurosurgical cranial procedures for brain tumors, and epilepsy.
Articles that discussed the following outcomes: communication disorders, prosodic impairments, aphasia, and recognition of various aspects of prosody, were included and were examined for assessments and reports of prosodic processing impairments. Methods of summary included study characteristics, sample characteristics, demographics, auditory processing task, age at injury, brain localization of the injury, time elapsed since TBI, reports between TBI and mental health, socialization and employment difficulties in studies assessing TBI and auditory processing evaluations. There were no limitations to the population size, age or gender.
We collected the electronic records in an Endnote data file. Titles and abstracts of the electronic search results were screened by one of the authors (WL) to identify the relevant studies. One of the authors (WL) and an undergraduate student (SW) independently evaluated the quality of the articles in the search and extracted data using data abstraction forms. The STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) criteria for quality assessment were applied to evaluate each article on study quality and external and internal validity [31 (link)]. Agreement between the two raters was very high (Cohen’s kappa = .89, P < 0.001). Results are reported according to the PRISMA guidelines [32 (link)].
Information was extracted primarily from the “Results”, “Discussion” and “Methods” sections with some input from the “Background” section. Information that was extracted included study characteristics, participant characteristics, localization and mechanisms of brain injury, severity of TBI, time-elapsed since injury, methods and results pertaining to prosodic processing post-TBI, author’s interpretation of results and conclusions. Internal validity was evaluated by examining the study design (blinding, statistical tests, reliability, participant recruitment, validity and biases) and external validity was based on whether or not the sample was representative of the entire population. Please note that the localization of brain injuries was reported based on the damage to the brain, not of the skull and surrounding protective tissues. However, localization was reported if damage to the surrounding tissue damaged the brain.

The primary efficacy outcome was the ordinal score on the modified Rankin scale (range, 0 [no symptoms] to 6 [death]) at day 90; the score was assessed in person, or by telephone if an in-person visit was not feasible, by a certified rater who was not aware of the trial-group assignments. The secondary efficacy outcome was functional independence (defined as a score on the modified Rankin scale of 0 to 2) at day 90. The primary safety outcomes were death within 90 days and the occurrence of symptomatic intracranial hemorrhage within 36 hours, defined as an increase of at least 4 points in the NIHSS score that was associated with brain hemorrhage on imaging within 36 hours after symptom onset.
Imaging outcomes were infarct volume measured at 24 hours (with a window of ±6 hours) after randomization; lesion growth (increase in volume of the infarct) between baseline imaging and 24 hours; reperfusion, defined as a greater than 90% reduction in the region of perfusion delay (Tmax of >6 seconds) between baseline and 24 hours; and complete recanalization of the primary arterial occlusive lesion at 24 hours on CTA or MRA. The technical efficacy of the endovascular procedure in establishing reperfusion was defined in the endovascular-therapy group by a modified Thrombolysis in Cerebral Infarction (TICI) score of 2b (50 to 99% reperfusion) or 3 (complete reperfusion).11 (link)

The occurrence of the post-thrombotic syndrome at 6, 12, 18, and 24 months was counted if the Villalta score at that visit was 5 or higher. The severity of the post-thrombotic syndrome was evaluated at 6, 12, 18 and 24 months with the use of the Villalta scale and the Venous Clinical Severity Score21 (link) (scores range from 0 to 27, with higher scores indicating more severe post-thrombotic syndrome). The proportion of patients with moderate-to-severe post-thrombotic syndrome (Villalta score, ≥10) was also assessed.
A major non–post-thrombotic syndrome treatment failure was assessed when any of three events occurred in the index leg: an unplanned endovascular procedure to treat severe venous symptoms within 6 months, venous gangrene within 6 months, or an amputation within 24 months. The combined outcome of the post-thrombotic syndrome or major non–post-thrombotic syndrome treatment failure was also assessed.
Patient-reported health-related quality of life at baseline and 24 months was assessed with the use of the generic Medical Outcomes Study 36-Item Short Form Health Survey (SF-36)22 and the venous disease–specific Venous Insufficiency Epidemiological and Economic Study Quality of Life (VEINES-QOL) measure.23 (link) Leg pain and leg swelling at baseline, 10 days, and 30 days were assessed with the use of a 7-point Likert pain scale (with higher scores indicating more severe pain)24 (link) and by measuring calf circumference, respectively.
In the pharmacomechanical-thrombolysis group, thrombus removal was quantified by independent central readers who scored venograms obtained before and after the procedure, using the proximal-vein components of the Marder score.25 (link) The modified Marder score ranges from 0 to 24, with 0 representing no thrombus and 24 representing complete thrombosis.
Safety outcomes included bleeding, recurrent venous thromboembolism, and death, which were reported throughout follow-up and summarized through 10 days and 24 months.26 (link) A detailed description of all trial outcomes is provided in the Supplementary Appendix.

Approval from the ethics committee of the A.O.R.N. Antonio Cardarelli Hospital was obtained. We retrospectively reviewed all consecutive cases in which ADAPT was performed using the pHLO AC in cases of acute thrombotic strokes at 2 comprehensive stroke centers (October 2019–November 2021). The use of the pHLO AC for endovascular recanalization procedures was at the operator’s discretion at both centers.
Inclusion criteria for endovascular therapy included LVO of anterior circulation as indicated by computed tomography (CT) angiography without evidence of major infarction (Alberta stroke program early CT score ≥6) on either CT or magnetic resonance imaging and a baseline National Institutes of Health stroke scale (NIHSS) score ≥6. All eligible patients received intravenous thrombolytic therapy (IVT), in the absence of contraindications to thrombolytic therapy, as evidenced by the American Guidelines [2 (link)] for the early management of acute ischemic stroke patients, a decision taken in any case in mutual agreement with the neurological team.

Stroke surgery was performed as previously described in detail (30 (link)). Due to the presence of a rete mirabile in sheep, endovascular methods are precluded and direct access to the cerebrovasculature is required [for details and review please see (10 (link), 44 (link)–46 (link))]. To achieve this, an incision was made between the right ear and orbital rim, coronoid process of the mandible lateralised, and skull base exposed to perform a small craniotomy using a pneumatic drill (Midas Rex® Legend Electric System, Medtronic USA). A 2 cm skull flap was removed, underlying dura breached, proximal middle cerebral artery (MCA) located, and an aneurysm clip (Aesculap YASARGIL® Aneurysm Clip, Germany) placed over the vessel which remained in situ for 2 h. The clip was subsequently removed to achieve reperfusion, dura closed watertight with synthetic matrix (Durepair®, Medtronic, USA) and cyanoacrylate adhesive (Bostik, Australia), cranioplasty performed using dental cement (Sledgehammer, Keystone, Germany), and surgical site closed in layers using polyglactin suture (Vicryl®, ETHICON). Arterial blood samples were obtained at hourly intervals intra-operatively to maintain the animal within normal physiological limits.

Patients were divided into 2 groups according to the treatment strategy: (1) CAS group (patients treated with stenting of the cervical lesion during MT) and (2) nonstenting group (patients treated with balloon angioplasty or thrombectomy with thromboaspiration and/or stent retriever, only aspiration of the extracranial ICA lesion, or deferred or no extracranial ICA intervention). Information on patients’ demographic characteristics, risk factors and comorbid conditions, National Institutes of Health Stroke Scale (NIHSS) scores, modified Rankin Scale (mRS) scores, smoking status, history of antithrombotic treatment, and intravenous thrombolysis administration were abstracted from the medical record review. Imaging characteristics included baseline Alberta Stroke Program Early CT Score (ASPECTS), etiology of the extracranial ICA lesion, occlusion site (as determined on computed tomography angiography or digital subtraction angiography), and degree of stenosis and lesion type (as determined on digital subtraction angiography). Stroke workflow time metrics were time from last known well (LKW) to groin puncture, door to arterial puncture, and arterial puncture to reperfusion. Procedural variables included intracranial stenting and/or angioplasty, cervical revascularization technique in reference to the ICA lesion (anterograde vs retrograde), and antiplatelet therapy regimens (when stenting was performed) categorized as single, dual, and/or intravenous antiplatelet(s) administered immediately before, during, or after the endovascular therapy procedure. Treatment with intravenous thrombolysis was determined at the discretion of the treating clinician. All intracranial occlusions were treated using stent retriever and/or contact aspiration catheters. The endovascular and medical therapeutic interventions were performed according to each institution’s protocol with the patient under conscious sedation or general anesthesia and at the discretion of the interventionalists.

A total of 38 vascular residents and neurosurgeons from the Department of Neurosurgery, Guangzhou First People's Hospital, and Tianjin Medical University General Hospital were recruited for this research. The trainees were divided into two groups: residents (residents with no endovascular experience) and surgeons (neurosurgeons with endovascular experience of 100–200 cases). The residents received a 2-day (3 h) endovascular skill training course, including didactic teaching and diagnostic cerebral angiography operation training on simulator Mentice Vascular Intervention Simulation Trainer (VIST; Gothenburg, Sweden, Guangzhou center) or Simbionix ANGIO Mentor (Simbionix, Cleveland, OH, Tianjin center).
Before training, a didactic course, including instruction on catheter handling, device selection, endovascular techniques, and manipulating simulators, was given to residents. The training time of all residents was 3 h. One-on-one training was provided throughout the training sessions by senior neuro-interventional doctors. Performance on cases with aortic arch type I (to avoid case difficulty bias) was used to assess early on the 1st day after didactic teaching, and this was repeated after the training by two highly experienced surgeons (mean experience of 20 years). Surgeons were also tested after learning to manipulate the simulator for 30 min.
The evaluation forms were used by on-site observation and video (screen recording) alike with two assessment tools: the checklist and the GRS of endovascular performance (Supplementary Tables 1, 2). Each examinee was evaluated by two raters (a total of four from two hospitals with a mean of 20 years of experience). The raters were trained by lecture and literally before the assessment. Screen recording recorded the overall core part of the procedure (Steps of the Procedure) to ensure an overview of the entire critical performance sequence; then, they were scored by all raters from two centers using the two tools. Video scoring was reviewed a month after direct observation (18 (link), 19 (link)). The order of videos was randomized, so the raters were blinded to the identity of operators.

This retrospective study was approved by the local institutional review board, which waived the need for patient informed consent as all examinations were performed as a part of the routine clinical workup. Between August 2016 to January 2020 patients with acute ischemic stroke from emergent large-vessel occlusion in the anterior circulation who underwent endovascular treatment with a mechanical thrombectomy were identified. Inclusion criteria were: (1) complete initial and follow-up clinical examinations and scores; (2) interpretable CT examinations, including supraaortic CT angiography; (3) acute middle cerebral artery occlusion; (4) endovascular thrombectomy of middle cerebral artery occlusion with/without prior systemic thrombolytic therapy. A flow chart demonstrating the patient recruitment process is presented in the Fig. 1. Basic demographic data (age and sex), comorbidities, preexisting risk factors for stroke, National Institutes of Health Stroke Scale (NIHSS) on admission and discharge, pre-stroke mRS, mRS on admission, discharge and after 3 month (90-day mRS), and treatment were retrieved for every patient from the electronic medical information system. Clinical evaluation on admission, discharge and after 3 months was performed by board-certified neurologists with at least 5 years of experience. The diagnosis of ischemic stroke was made based on the clinical presentation with acute neurological deficit confirmed by imaging, including vascular imaging with large-vessel occlusion of a middle cerebral artery [14 (link)]. All patients underwent diagnostic CT prior to systemic thrombolysis and endovascular intervention. The occlusion level was determined on admission CT and confirmed by digital subtraction angiography (DSA). The endovascular interventions for all patients were performed by board-certified experienced neuroradiologists on a biplane angiographic system under general anesthesia. Post endovascular revascularization success following DSA was assessed using the Thrombolysis in Cerebral Infarction (TICI) grading system.
