Development of Blood Vessels01:07

Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Overview of Blood Vessels01:14

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...

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...
Varicose Veins I: Introduction01:26

Varicose Veins I: Introduction

Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Area of Science:

  • Dermatology
  • Pediatrics
  • Vascular Surgery

Background:

  • Vascular birthmarks are broadly categorized into hemangiomas and vascular malformations.
  • Hemangiomas exhibit rapid neonatal growth and involution, while vascular malformations are present at birth and grow with the child.

Purpose of the Study:

  • To differentiate between hemangiomas and vascular malformations for appropriate therapeutic management.
  • To highlight the importance of modern diagnostic tools and multidisciplinary care for vascular birthmarks.

Main Methods:

  • Classification of vascular birthmarks into hemangiomas and vascular malformations.
  • Utilizing modern diagnostic methods to distinguish between low-flow and high-flow lesions.

Main Results:

  • Hemangiomas require treatment based on stage and type, with modern options available.
  • Vascular malformations necessitate accurate diagnosis for effective management.

Conclusions:

  • The "benign neglect" approach for hemangiomas is outdated due to available treatments.
  • Multidisciplinary care in specialized vascular centers is crucial for managing both hemangiomas and vascular malformations.
