Which artery is supply the cervical part of the esophagus?

the inferior thyroid artery
The blood supply of the cervical esophagus is derived from the inferior thyroid artery, while the blood supply for the thoracic esophagus comes from the bronchial arteries and the aorta.

What vein supplies the esophagus?

Those from the thoracic oesophagus drain predominantly into the azygos veins and, to a lesser extent, the hemiazygous, intercostal and bronchial veins. Those from the cervical oesophagus drain into the inferior thyroid vein.

What is UES dysfunction?

Upper esophageal sphincter (UES) dysfunction occurs when the muscles of the upper esophagus, specifically the cricopharyngeus, develop impaired relaxation. Symptoms include progressive dysphagia from pills to solids and then liquids. Diagnosis is made from a thorough history and Modified Barium Swallow Study (MBSS).

What is Killian Jamieson diverticulum?

A Killian-Jamieson diverticulum is an outpouching from the lateral wall of the proximal cervical esophagus. These diverticula are rare and are distinct from the more commonly known Zenker’s diverticulum. Literature regarding Killian-Jamieson diverticula and its suggested management is scarce.

What does the inferior phrenic artery supply?

The inferior phrenic artery is a paired vessel that arises from the abdominal aorta….Inferior phrenic artery.

Origin	Abdominal aorta
Branches	Ascending branch, descending branch, superior suprarenal branches
Supply	Abdominal surface of diaphragm, distal esophagus, suprarenal glands, capsule of liver, superior pole of spleen

What does the superior phrenic artery supply?

The superior phrenic artery is a small paired artery that arises from the anterior aspect of the lower part of the thoracic aorta, just before it passes through the aortic hiatus of the diaphragm. The superior phrenic artery supplies the posterior part of the superior surface of the diaphragm.

What is the blood supply of the middle third esophagus?

The blood supply to the esophagus can roughly be divided into thirds, with anastamoses between each area of supply. More specifically, it can refer to: Esophageal branches of inferior thyroid artery (top third) Esophageal branches of thoracic part of aorta (middle third)

Which veins drain the esophagus?

Venous drainage of the cervical esophagus is through the inferior thyroid vein, while the thoracic esophagus drains via the azygous vein, the hemiazygous vein, and the bronchial veins. The abdominal esophagus drains through the coronary vein.

How can I heal my UES?

The definitive treatment for cricopharyngeal dysfunction is a procedure called cricopharyngeus muscle myotomy in which physicians cut the UES in a way that prevents it from over-contracting, so food is no longer blocked from entering the esophagus.

What is Killian triangle?

Killian’s dehiscence (also known as Killian’s triangle) is a triangular area in the wall of the pharynx between the cricopharyngeus and thyropharyngeus which are the two parts of the inferior constrictors(also see Pharyngeal pouch). It can be seen as a locus minoris resistentiae.

What is Epiphrenic diverticulum?

Epiphrenic diverticulum, also known as a pulsion diverticulum, is a rare type of esophageal diverticulum occurring in the distal 10 centimeters (CM) of the esophagus most commonly 4cm to 8 cm above the gastric cardia.[1] These diverticula are made up of the mucosal and submucosal lining, herniating through a weakness …

What does right phrenic artery supply?

One of these branches anastomoses with its counterpart branch of the right inferior phrenic artery with which it supplies the distal esophagus and tendinous diaphragm.

What does the SMA supply blood to?

The superior mesenteric artery supplies the midgut from the ampullary region of the second part of the duodenum to the splenic flexure of the large intestine. The inferior pancreaticoduodenal artery arises from the SMA and, along with the superior pancreaticoduodenal artery, supplies the head of the pancreas.

Which artery supplies blood to the diaphragm?

The blood supply to the diaphragm is from the superior phrenic, musculophrenic, inferior phrenic, pericardiacophrenic, and lower internal intercostal arteries. The superior phrenic arteries arise from the thoracic aorta.

What artery runs with the phrenic nerve?

The phrenic nerve is accompanied by the pericardiophrenic artery and superior phrenic vein throughout its course. The nerve, artery, and vein originate at the neck root and descend, parallel, along the lateral aspects of the pericardial sac, ultimately terminating at the superior aspect of the diaphragm.

What nerve supplies the esophagus?

the vagus nerve
The esophagus is innervated by both parasympathetic and sympathetic nerves. The parasympathetics control peristalsis via the vagus nerve. The medullary vagal postganglionic efferents arise from the lower motor neurons in the nucleus retrofacialis and the compact formation of the nucleus ambiguus.

What is cervical esophagus?

Cervical esophagus: This is the uppermost part of the esophagus, and it extends from the hypopharynx to the sternal notch (the indentation in the middle of the neck between the two collarbones).

What vein receives blood from terminal esophagus?

The left gastric vein runs to the left along the lesser curvature, receiving the esophageal veins below the esophageal hiatus in the diaphragm. It usually drains directly into the portal vein at the superior border of the pancreas.

What is an esophageal diverticulum?

An esophageal diverticulum known as a traction diverticulum occurs when there is an external force on the wall of the esophagus that creates the pouch. This most commonly occurs in the middle area of the esophagus. 4

Is there an esophageal segmental blood supply complementing the esophagus?

The obvious viability of these long esophageal segments detached from the segmental blood supply prompted us to preserve and use them in reconstruction. These observations suggest that there is a rich intramural arterial and venous network complementing the segmental blood supply of the esophagus.

What is the pathophysiology of diverticulum regurgitation?

Regurgitation caused by a diverticulum often occurs at night when lying down, which can lead to choking, aspiration pneumonia (a lung infection caused by pulmonary aspiration, the entry of secretions or foreign material into the trachea and lungs), and lung abscesses.

What is Zenker’s diverticula (pharyngoesophageal)?

Zenker’s diverticula (pharyngoesophageal) is the most common type of diverticula of the esophagus. Zenker’s diverticula are usually located in the back of the throat, just above the esophagus Midthoracic diverticula, in the mid-chest Epiphrenic diverticula, above the diaphragm
