Can you Ligate external carotid artery?

Can you Ligate external carotid artery?

External carotid artery ligation (BECAL) is usually practiced in neck zone III or maxillofacial trauma cases. Interventional radiology has reduced the number of open procedures. BECAL is reported in post-operative bleeding control and onco-surgery, but not in maxillofacial trauma.

Where do you Ligate an external carotid artery?

Ligation of the external carotid artery (ECA) can be performed with the patient under local or general anesthesia. A horizontal skin incision is made between the hyoid bone and the superior border of the thyroid cartilage.

What is carotid artery ligation?

Partial carotid artery ligation involves ligating all distal branches of the left carotid artery except the superior thyroid artery, creating a low-flow state with commensurate vascular remodeling over 2 or more weeks.

Why is external carotid artery ligated above superior thyroid artery?

The artery and nerve are close to each other higher up but diverge near the gland. Thus in order to avoid injury to the external laryngeal nerve, the superior thyroid artery is ligated as near to the gland as possible.

Which artery is ligated in posterior epistaxis?

Ligation of the sphenopalatine and posterior nasal arteries is a very effective treatment for severe posterior epistaxis. Concomitant anterior ethmoidal artery ligation may be more effective than sphenopalatine artery/posterior nasal artery ligation alone.

Where do you Ligate lingual artery?

The lingual artery passes between the middle constrictor of the pharynx and the hyoglossus muscles. [2] At the anterior border of the hyoglossus muscle, the lingual artery ascends to the tip of the tongue.

How do you Ligate internal maxillary arteries?

The internal maxillary artery and 3 of its terminal branches (ie, sphenopalatine, descending palatine, pharyngeal) are elevated with nerve hooks, then clipped. The posterior sinus wall is then packed with Gelfoam, and the gingivobuccal incision is closed.

What’s in carotid sheath?

The carotid sheath is an important landmark in head and neck anatomy and contains several vital neurovascular structures, including the carotid artery, jugular vein, vagus nerve, and sympathetic plexus. It extends upwards from the arch of the aorta and terminates at the skull base.

Where do you Ligate superior thyroid?

Most surgeons agree that identifying the SLN, in contrast to the RLN, is unnecessary. Instead, ligate the terminal branches of the superior thyroid artery as close to the thyroid capsule as possible to avoid damaging the nerve.

What does the ECA supply?

The ECA provides the majority of blood supply to the meninges, scalp, and face. It originates at the carotid bifurcation and lies superficial and medial to the ICA.

What is sphenopalatine artery ligation?

An endoscopic transnasal approach for ligation of the terminal branch of the internal maxillary artery, the sphenopalatine artery, provides an alternative to transantral ligation. We have used endoscopic ligation of the sphenopalatine artery to treat 38 patients requiring surgical therapy for epistaxis.

Which artery is known as artery of epistaxis?

sphenopalatine artery
The sphenopalatine artery (nasopalatine artery) is an artery of the head, commonly known as the artery of epistaxis….

Sphenopalatine artery
Source	maxillary artery
Branches	posterior lateral nasal branches posterior septal branches
Supplies	frontal, maxillary, ethmoidal, and sphenoidal sinuses

Can facial artery be ligated?

Background. The accepted method for submandibular gland excision traditionally includes ligation of the facial artery (FA) as suggested by a host of surgical atlases. Preservation of the FA may be significant in recon- structive procedures of the head and neck and its ligation may altogether be obviated.

What is SPA ligation?

SPA ligation is generally indicated for intractable posterior epistaxis that does not settle following 24hrs of adequate anterior and posterior nasal packing, and for recur- rent unilateral epistaxis unrelated to an underlying systemic disease or a drug rela- ted blood dyscrasia.

Can we Ligate maxillary artery?

Intraoral ligation of the maxillary artery is a safe, rapid and effective technique for control of in- tractable epistaxis. 2. The technique eliminates the Caldwell-Luc op- eration and the use of the operating microscope.

What are the 5 contents of the carotid sheath?

Contents

• the common carotid artery.
• parts of the internal carotid artery and the external carotid artery.
• the internal jugular vein.
• the vagus nerve.
• part of the recurrent laryngeal nerve.
• the deep cervical lymph nodes.

What are the three components located within the carotid sheath?

As previously described, the carotid sheath contains the carotid arterial system, the internal jugular vein, and vagus nerve, and the visceral fascia contains the esophagus and trachea.

Which artery is ligation in thyroidectomy?

the inferior thyroid artery
Background: Bilateral truncal ligation (BTL) of the inferior thyroid artery (ITA) is frequently used during subtotal thyroidectomy to reduce the risk of post-operative bleeding as well as to reduce the blood loss intra-operatively.

Which nerve may be easily damaged when the superior thyroid artery is ligated?

the superior laryngeal nerve
The external branch of the superior laryngeal nerve (EBSLN) is at risk of injury during thyroid operations when dissection of the superior pole and ligation of the superior thyroid vessels (STV) are carried out. The rates of injury to this nerve are highly variable in the literature, but can be as high as 58% (1).
