Insights

COVID-19 causes microvascular damage, leading to widespread perfusion issues and thrombosis. Early anticoagulant therapy and monitoring are crucial for managing this vascular disease.

Area of Science:

  • Vascular Biology
  • Infectious Diseases
  • Pathology

Background:

  • COVID-19 is associated with increased mortality, elevated D-dimer levels, and a prothrombotic state.
  • Existing diagnostic and treatment guidelines for COVID-19 may not fully address the observed thromboembolic complications.
  • A new vascular disease concept has been proposed to explain COVID-19's clinical manifestations.

Purpose of the Study:

  • To analyze current medical, laboratory, and imaging data on COVID-19.
  • To investigate the underlying pathophysiology of COVID-19 beyond impaired pulmonary ventilation.
  • To establish the role of microvascular damage and thrombosis in COVID-19.

Main Methods:

  • Comprehensive review of medical, laboratory, and imaging data from COVID-19 patients.
  • Pathological and imaging investigations to assess organ perfusion and microvasculature.
  • Analysis of viral impact (SARS-1 and SARS-2) on vascular structures.

Main Results:

  • COVID-19 symptoms and diagnostic findings are not solely explained by impaired lung ventilation.
  • Perfusion disturbances, initially in the lungs and subsequently in other organs, characterize the COVID-19 syndrome.
  • Microvascular damage by SARS-CoV-2 leads to microthrombotic changes, progressing to macrothrombosis and emboli.

Conclusions:

  • COVID-19 should be understood as a systemic vascular disease driven by viral-induced microvascular damage.
  • Anticoagulant prophylaxis, vigilant laboratory and CT imaging monitoring, and prompt anticoagulant therapy are indicated.
  • This approach aims to mitigate thromboembolic complications and improve outcomes in COVID-19 patients.

Veins of Head and Neck01:19

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Veins as Blood Reservoirs01:10

Veins as Blood Reservoirs

Veins, while chiefly responsible for circulating blood back to the heart, also function as storage vessels for blood. They house approximately 64 percent of the body's total blood volume, a feat made possible by their high capacitance—the inherent ability to expand and accommodate large volumes of blood, even under low pressure. The large diameter and thin walls of veins augment their distensibility, significantly more so than arteries, due to their classification as capacitance...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Overview of Blood Vessels

The human cardiovascular system comprises five primary types of blood vessels: arteries, arterioles, veins, venules, and capillaries, each serving unique functions.
Arteries and Arterioles: Arteries are muscular and elastic vessels that primarily carry oxygenated blood from the heart to body tissues, except for the pulmonary artery, which carries deoxygenated blood. They have thick walls to withstand high pressure and contain a layer of muscle tissue, allowing them to expand or contract as...

Overview of Systemic Veins01:11

Overview of Systemic Veins

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...

Overview of Systemic Arteries

The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...
