	~~'''Aortocaval compression syndrome''', also known as '''supine hypotensive syndrome''', is a condition that can occur in pregnant women when the gravid uterus compresses the~~ [[~~inferior vena cava]~~] ~~and [[aorta~~]~~] while the woman is in a supine position. This compression can lead to decreased venous return to the heart, reduced cardiac output, and subsequent hypotension.~~		[[File:Areca_catechu_-_Köhler–s_Medizinal-Pflanzen-014.jpg\|Areca catechu illustration\|thumb\|right]]

	~~==Pathophysiology==~~		'''Areca catechu''', commonly known as the areca palm, betel palm, or supari, is a species of palm which grows in much of the tropical Pacific, Asia, and parts of east Africa. It is best known for its seed, commonly referred to as the areca nut or betel nut, which is chewed along with betel leaf for its psychoactive effects.
	~~During pregnancy~~, the ~~enlarging uterus can exert pressure on the inferior vena cava~~, ~~which~~ is ~~the large vein that carries deoxygenated blood from the lower body back to the heart. When~~ a ~~pregnant woman lies on her back, the weight~~ of the ~~uterus can compress the inferior vena cava against the spine~~, ~~reducing venous return~~. ~~This can lead~~ to ~~a decrease in [[cardiac output]] and a drop in [[blood pressure]]~~, ~~resulting in symptoms of hypotension~~.

	The aorta, the main artery carrying oxygenated blood from the heart to the rest of the body, can also be compressed, although it is less susceptible to compression due to its thicker walls and higher pressure. However, aortic compression can still contribute to decreased perfusion of the lower body and placenta.		==Description==

	~~==Symptoms==~~		[[File:Areca_Palm_Seeds_Forming_Coorg_Feb24_A7C_09499.jpg\|Areca catechu seeds forming\|thumb\|left]]
	~~Symptoms of aortocaval compression syndrome can include~~:
	* Dizziness or lightheadedness
	* Nausea
	* Sweating
	* Pallor
	* Tachycardia
	* Fainting

	~~These symptoms typically occur when the woman~~ is ~~lying flat on her back~~ and are ~~relieved by changing position~~, ~~such as lying on the left side~~.		The areca palm is a medium-sized and graceful tree, growing straight to 20 meters (66 feet) tall, with a trunk 10–15 cm in diameter. The leaves are 1.5–2 meters long, pinnate, with numerous, crowded leaflets.

	~~==Diagnosis==~~		The fruit of the areca palm is a drupe, oval-shaped, and orange to red when ripe. The seed inside is the areca nut, which is about 2–3 cm in diameter.
	~~Diagnosis~~ of ~~aortocaval compression syndrome is primarily clinical, based on the presence of symptoms when~~ the ~~patient~~ is in a ~~supine position~~ and ~~their resolution upon repositioning~~. It is ~~important to differentiate this condition from other causes of hypotension~~ in ~~pregnancy~~.

	==~~Management~~==		==Cultivation==
	The primary management strategy for aortocaval compression syndrome is prevention and alleviation of symptoms by avoiding the supine position, especially in the later stages of pregnancy. Pregnant women are advised to lie on their left side, which helps to relieve pressure on the inferior vena cava and improve venous return.

	~~In cases where the supine position is unavoidable, such as during certain medical procedures, tilting the patient to the left or using a wedge under the~~ right ~~hip can help mitigate the effects of compression.~~		[[File:Areca_nut_garden_(1).jpg\|Areca catechu garden\|thumb\|right]]

	~~==Prognosis==~~		Areca catechu is cultivated for its nuts in India, Bangladesh, Sri Lanka, Malaysia, Taiwan, and many other countries. The plant prefers a tropical climate and is often grown in gardens and plantations.
	~~With appropriate management~~, ~~the prognosis for aortocaval compression syndrome~~ is ~~excellent. Avoiding the supine position typically resolves symptoms~~ and ~~prevents complications~~.

	~~==Related pages==~~		The cultivation of areca palms requires well-drained soil and a warm, humid climate. The trees are usually planted in rows and require regular watering and fertilization.
