The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1] [2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4]
The innominate artery should be debrided to healthy tissue and closed with a monofilament suture. [5] Next, the damaged segments of the trachea and the artery should be excised followed by reconstruction with a primary end to end anastomosis of the trachea. Innominate artery ligation leaves the carotid and subclavian circulations intact. [4 ...
A tracheostomy tube may be single or dual lumen, and also cuffed or uncuffed. A dual lumen tracheostomy tube consists of an outer cannula or main shaft, an inner cannula, and an obturator. The obturator is used when inserting the tracheostomy tube to guide the placement of the outer cannula and is removed once the outer cannula is in place.
The thyroid ima artery (thyroidea ima artery, arteria thyroidea ima, thyroid artery of Neubauer or the lowest thyroid artery) is an artery of the head and neck.It is an anatomical variant that, when present, supplies blood to the thyroid gland primarily, or the trachea, the parathyroid gland and the thymus gland (as thymica accessoria) in rare cases.
In the innominate artery, the average reading is 110/70 mmHg, the right subclavian artery averages 120/80 and the abdominal aorta is 110/70 mmHg. [25] The relatively uniform pressure in the arteries indicate that these blood vessels act as a pressure reservoir for fluids that are transported within them.
Potentially fatal complications more often associated with prolonged intubation or tracheotomy include abnormal communication between the trachea and nearby structures such as the innominate artery (tracheoinnominate fistula) or esophagus (tracheoesophageal fistula).
A tracheotome is a medical instrument used to perform an incision in the trachea with a cutting blade operated by a powered cannula. It is often called a tracheostomy tube because once it enters the stoma in the trachea, a breathing tube is connected to a ventilator and oxygen is provided to the lungs.
Cricothyrotomy is used as emergency surgical access due to being fast and simple. Another surgical airway method is called tracheostomy. Tracheostomy is done in the operating room by a surgeon. This is the preferred method for patients requiring long-term ventilation. Tracheostomy uses skin puncture and dilators to insert the tracheostomy tube ...
