Pregnancy causes significant vascular changes in the skin and mucosa, including palmar erythema and spider telangiectasias. Most of these gestational vascular changes resolve postpartum, though some vascular tumors may require laser treatment.
Area of Science:
- Dermatology
- Obstetrics
- Vascular Biology
Background:
- Pregnancy involves profound endocrine changes impacting skin and mucosal microvasculature.
- Gestational vascular alterations are common, affecting skin, oral cavity, and genitalia.
Purpose of the Study:
- To review the common vascular changes during pregnancy.
- To discuss their clinical presentation and postpartum outcomes.
- To mention potential treatments for persistent vascular lesions.
Main Methods:
- Literature review of common pregnancy-related vascular changes.
- Clinical observation of skin and mucosal alterations.
- Discussion of postpartum regression and treatment options.
Main Results:
- Palmar erythema and spider telangiectasias are frequent; the latter are less common in darker skin.
- Vascular tumors (hemangiomas, glomus tumors) affect one-third of pregnant women.
- Edema, venous hypertension, varicosities, gingivitis, and mucosal changes (vaginal, vulvar) are also common.
Conclusions:
- Most pregnancy-associated vascular changes are transient and resolve postpartum.
- Some vascular tumors may persist and require intervention, such as vascular laser or intense pulsed light therapy.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Overview of Systemic Veins
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 middle...

Overview of Blood Vessels
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...
