Insights

COVID-19 did not significantly impact outcomes for acute ischemic stroke (AIS) patients undergoing mechanical thrombectomy (MT). However, COVID-19 positive patients experienced longer hospital stays and delays in groin puncture, highlighting potential pandemic-related treatment challenges.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Cardiology

Background:

  • COVID-19 is recognized as a risk factor for acute ischemic stroke (AIS).
  • The pandemic saw a global decrease in mechanical thrombectomy (MT) procedures.
  • Existing research on MT outcomes in COVID-19 associated AIS presents conflicting findings.

Purpose of the Study:

  • To evaluate the clinical characteristics and outcomes of AIS patients treated with MT.
  • To compare outcomes between patients with and without SARS-CoV-2 infection during the pandemic.
  • To identify potential disparities in stroke care due to COVID-19.

Main Methods:

  • Retrospective analysis of AIS patients treated with MT at a Comprehensive Stroke Centre.
  • Comparison of clinical profiles, stroke size, and short-term outcomes between COVID-19 positive and negative groups.
  • Utilized perfusion CT with RAPID software for stroke size assessment.

Main Results:

  • No statistically significant differences in clinical profiles, stroke size, or patient outcomes (NIHSS, mRS, mortality) were observed between COVID-19 positive and negative groups.
  • A significant increase in time from hospital arrival to groin puncture was noted in COVID-19 positive patients.
  • COVID-19 positive patients had a significantly longer hospitalisation duration.

Conclusions:

  • Concomitant SARS-CoV-2 infection did not negatively affect the outcomes of AIS patients treated with MT.
  • Further validation in larger, multicentre studies is recommended to confirm these findings.
  • The study highlights potential delays in MT procedures for COVID-19 patients during the pandemic.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
