Insights

The COVID-19 pandemic led to increased mortality for patients with aneurysmal subarachnoid hemorrhage in Peru. Healthcare resource reallocation may have impacted care for critical non-COVID-19 conditions.

Area of Science:

  • Neurology
  • Public Health
  • Infectious Diseases

Background:

  • The COVID-19 pandemic significantly disrupted global healthcare systems.
  • Peru faced one of the highest COVID-19 case fatality rates worldwide.
  • Aneurysmal subarachnoid hemorrhage (SAH) is a critical neurological emergency.

Purpose of the Study:

  • To compare outcomes for aneurysmal subarachnoid hemorrhage (SAH) patients before and during the COVID-19 pandemic in Peru.
  • To assess the impact of pandemic-related healthcare changes on SAH patient management and mortality.
  • To identify factors associated with increased mortality during the pandemic.

Main Methods:

  • Retrospective comparative study of aneurysmal SAH patients.
  • Two study periods: 2019 (pre-pandemic) and 2020 (first wave of pandemic).
  • Analysis of patient demographics, comorbidities, COVID-19 status, clinical presentation, treatment, and outcomes.

Main Results:

  • 114 patients analyzed; 65 in 2019 and 49 in 2020.
  • Higher mortality in 2020 (36.7%) compared to 2019 (15.4%).
  • Increased complications (sepsis, respiratory failure, acute kidney failure) observed in 2020; no direct link between COVID-19 infection and SAH mortality.

Conclusions:

  • Aneurysmal SAH patients faced worse outcomes during the COVID-19 pandemic.
  • Potential healthcare resource diversion to COVID-19 may have negatively impacted SAH care.
  • Maintaining essential services for non-infectious emergencies during pandemics is crucial.

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
