What is sphenopalatine artery ligation?
Objective: Sphenopalatine artery ligation is a commonly employed surgical intervention for control of posterior epistaxis unresponsive to nasal packing.
What is artery ligation?
In surgery or medical procedure, a ligature consists of a piece of thread (suture) tied around an anatomical structure, usually a blood vessel or another hollow structure (e.g. urethra) to shut it off.
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 is Crista Ethmoidalis?
The crista ethmoidalis is a small, raised bony crest just anterior or anterior-inferior to the sphenopalatine foramen. ▪ The crista ethmoidalis is located within 1 mm of the sphenopalatine foramen in 95% of cadaveric specimens.
What is a spa ligation?
SPA ligation is generally indicated for intractable posterior epistaxis that does not settle following 24 hours of adequate anterior and posterior nasal packing, and for recurrent unilateral epistaxis unrelated to an underlying systemic disease or a drug related blood dyscrasia.
Why is sphenopalatine artery called artery of epistaxis?
The sphenopalatine artery, formerly known as the nasopalatine artery, is the terminal branch of the maxillary artery that is the main supply to the nasal cavity. It is colloquially know as the artery of epistaxis given its common involvement in cases of nose bleeds.
Which is the artery of epistaxis?
The anterior ethmoid, greater palatine, sphenopalatine, and superior labial arteries all form a plexus of vessels in the anteroinferior nasal septum. Kiesselbach plexus is the source of the majority of nose bleeds.
How do you Spgate the sphenopalatine artery?
Temporoparietal Flap Make a large maxillary antrostomy to identify the sphenopalatine artery and the posterior nasal artery. Ligate the arteries and dissect them proximally into the pterygopalatine fossa while removing the posterior wall of the maxillary sinus.
How do you perform a spa ligation?
Initial surgical steps
- Remove all nasal packing.
- Irrigate the nasal cavity with warm saline.
- Apply topical anesthesia by inserting ribbon gauze or neurosurgical patties soaked in 2 mL of 1:1000 adrenaline between the inferior turbinate and the nasal septum and in the middle meatus if possible.
Does ligation of the IMA affect outcomes of sigmoid colon and rectal cancer?
This meta-analysis was performed to compare the effect of high versus low ligation of the IMA during curative resection of sigmoid colon and rectal cancer on outcomes such as AL, overall morbidity, postoperative mortality, recurrence, and survival.
Does high ligation reduce anastomotic tension and leakage?
Meanwhile, several clinical studies have demonstrated that high ligation allows complete mobilization of the proximal colonic limb and thus helps reduce anastomotic tension [ 14 ]. Interestingly, previous meta-analyses have arrived at different conclusions about the incidence of anastomotic leakage (AL) with the two approaches.
What is tubal ligation?
tubal ligation sterilization of the female by constricting, severing, or crushing the fallopian tubes; constriction may be with an encircling ring or other ligature.

What is ligation surgery?
Surgery The process of tying off blood vessels to block blood flow to a part of the body or to a tumor. See Band ligation. 1. Application of a ligature. 2. The act of binding or annealing. The surgical process in which a string ( LIGATURE) is placed tightly around a tissue and tied.
