Intraoperative hybrid technique for excision of temporal bone paraganglioma: A case report.

Background: Temporal bone paragangliomas are vascularized neoplasms. Although preoperative angioembolization serves as a valuable approach to reduce intraoperative blood loss, it comes with an elevated risk of cranial neuropathies, offers no assurance of complete hemostasis, and precludes real-time adjustments during surgery.

Methods: A 74-year-old patient presented with recurrent episodes of ear bleeding.

Coronary balloon-assisted navigation of aspiration catheter for stroke thrombectomy.

In recent years, A Direct Aspiration First Pass Technique (ADAPT) has emerged as an effective and safe method of thrombectomy. Large trials have shown noninferiority of ADAPT compared to primary stent retriever approach, while new studies emphasize on its shorter procedural time with potentially fewer complications and costs..

Evaluating a Novel EEG-Based Index for Stroke Detection Under Anesthesia During Mechanical Thrombectomy.

Background: The rapid identification of acute stroke (AS) during and after anesthesia might lead to early interventions and improved outcomes. We investigated a novel 2-channel electroencephalogram (EEG)-based marker for stroke detection-the lateral interconnection ratio (LIR)-in AS patients having endovascular thrombectomy (EVT) with general anesthesia (GA) or sedation. The LIR in 2 reference groups of patients without postoperative neurological complications was used for comparison.

Acute frame coil migration during filling coil retrieval in a cerebral aneurysm embolization case: A possible result of a venturi effect?

Coil migration is a known complication of endovascular coiling of cerebral aneurysms. We report an acute coil migration occurring during coiling of an unruptured anterior choroidal aneurysm, while a separate coil was retrieved into the microcatheter concomitantly without direct contact between the coils. The "pulling" of a previously deployed stable coil is presented as an adverse effect that should be noted.

The Future of Stroke Interventions.

Mechanical thrombectomy (MT) has revolutionized the treatment of large-vessel occlusion stroke and markedly improved patient outcomes. Unfortunately, there remains a large proportion of patients that do not benefit from this technology. This review takes a look at recent and upcoming technologies that may help to increase the number of MT-treated patients, thereby improving their outcomes.

Infarct Core Reliability by CT Perfusion is a Time-Dependent Phenomenon.

Background And Purpose: In the setting of an extended time window for endovascular treatment (EVT) for acute stroke patients, computed tomography perfusion (CTP) has become a major tool in patient selection. However, there are some data suggesting that the initial ischemic core may be overestimated by CTP depending on stroke onset time. This study aims to evaluate possible predictors of overestimation of infarct core by CTP.

Favorable revascularization therapy in patients with ASPECTS ≤ 5 on DWI in anterior circulation stroke.

Background: A low baseline Alberta Stroke Programme Early CT Score (ASPECTS) is strongly associated with low rates of favorable outcome in patients with acute stroke.

Objective: To evaluate the efficacy and safety of revascularization therapy in patient with ASPECTS ≤5 in anterior circulation infarct.

Methods: We retrospectively analyzed 108 consecutive patients presenting low ASPECTS on diffusion-weighted imaging.

Acute Kidney Injury After Primary Angioplasty: Is Contrast-Induced Nephropathy the Culprit?

Background: Acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI) is frequently interpreted as contrast-induced AKI but may result from other insults. We aimed to determine the causal association of contrast material exposure and the incidence of AKI following pPCI using a control group of propensity score-matched patients with ST-segment-elevation myocardial infarction who were not exposed to contrast material.

Methods And Results: We studied 2025 patients with ST-segment-elevation myocardial infarction who underwent pPCI and 1025 patients receiving fibrinolysis or no reperfusion who were not exposed to contrast material during the first 72 hours of hospital stay (control group).

BIOFLOW-III satellite-One-year clinical outcomes of diabetic patients treated with a biodegradable polymer sirolimus-eluting stent and comprehensive medical surveillance.

Background: Drug-eluting stents with biodegradable polymer might be particularly useful in diabetic patients who are at increased risk for target lesion/target vessel revascularization. We therefore aimed at assessing the safety and performance of a biodegradable polymer sirolimus-eluting stent (BP-SES) in combination with comprehensive optimal medical therapy following coronary interventions.

Methods: This prospective, multicenter registry was conducted at six centers in Israel.

Novel Method for Real Time Co-Registration of IVUS and Coronary Angiography.

Objectives: We present our experience with a novel method for real time co-registration of intravascular ultrasound (IVUS) and coronary angiography.

Background: A major limitation of the current practice of concomitant use of coronary angiography and IVUS is that the locations of the acquired IVUS images are not correlated with their exact locations on the vessel roadmap obtained by coronary angiography.

Methods: Phantoms simulating the coronary tree were used to test the accuracy and potential of co-registration.

Heart failure in patients with diabetes undergoing primary percutaneous coronary intervention.

Introduction: Diabetes mellitus is associated with increased risk after acute coronary syndromes. Primary percutaneous coronary intervention is the most effective method of reperfusion for acute ST-elevation myocardial infarction and can limit the ischaemic damage to the left ventricle. However, there are few data on the impact of diabetes mellitus on the risk of heart failure following primary percutaneous coronary intervention.

A randomized study comparing the use of a pelvic lead shield during trans-radial interventions: Threefold decrease in radiation to the operator but double exposure to the patient.

Objectives: To determine the efficacy of a 0.5-mm lead apron across the patient's abdomen in addition to standard operator protection for the reduction of scatter radiation on operator and patient radiation exposure

Background: Cardiac angiography using the radial access compared to the femoral approach is associated with reduced complication rate and improved patient comfort but has significantly increased radiation dose. Improvements in radiation protection are needed

Methods: We randomly assigned 332 patients undergoing coronary angiography to a group with pelvic lead shielding and a group with standard protection.

Should proximal LAD be treated differently? Insights from a large DES stent registry.

Background: The current revascularization treatment recommendation is different according to lesion location and a higher recommendation is given to surgery for proximal LAD (pLAD) lesions over PCI. This is based on previous studies and expert opinion. We aimed to investigate whether indeed there is a difference in outcome with respect to LAD lesion location while using a drug eluting stent (DES).

Direct comparison between coronary computed tomography and invasive angiography for calculation of SYNTAX score.

Aims: We aimed to test the feasibility of calculating SYNTAX score from coronary computed tomographic angiography (CCTA) compared to from invasive coronary angiography (ICA).

Methods And Results: SYNTAX score was independently and blindly calculated from CCTA and from ICA in 104 patients, age 57±10, with significant (>50%) stenoses in 1.7±0.

Repeat in-stent restenosis of drug-eluting stents in a bifurcation treated successfully with kissing drug eluting balloons.

The use of drug-coated balloons (DEB) for preventing restenosis is new and has received increasing interest. We present a patient who was admitted with recurrent angina with repeat interventions for restenosis events in a very short time using both BMS and DES. The restenosis was treated with kissing drug eluting balloons in the LAD-Diagonal bifurcation.

Gender impact on prognosis of acute coronary syndrome patients treated with drug-eluting stents.

Women have a higher risk of adverse outcomes after percutaneous coronary intervention (PCI) than men. However, in acute coronary syndrome (ACS), long-term outcomes after contemporary PCI with drug-eluting stent (DES) have not been fully investigated. We aimed to test the impact of gender on outcomes in patients with ACS after PCI with DES.

Ticagrelor: an investigational oral antiplatelet treatment for reduction of major adverse cardiac events in patients with acute coronary syndrome.

Acute coronary syndromes (ACS) are the leading cause of mortality and one of the main reasons for hospital admissions in the developed nations. Due to high rates of mortality and reinfarction, ACS represent a major public health concern. Platelets play a central role in atherothrombosis, the main pathologic substrate in ACS.
