Study Notes
- Various methods can be used to treat nasal bleeding, including nasal cautery, endoscopic-assisted nasal cautery, and chemical cauterization.
- Absorbable and non-absorbable nasal packing can also be used to provide a stable platform for fibrin and platelet aggregation.
- Chitosan is a biocompatible polymer that can assist in stopping bleeding.
- Posterior packing may be necessary, but it carries risks such as ulceration, perforation, and toxic shock syndrome.
- Comorbid systemic factors such as excessive bleeding or abnormal clotting may need to be addressed.
- Surgical management options include sphenopalatine artery ligation and ethmoidal artery ligation.
- Other sources of intranasal bleeding include sinonasal tumors, high volume venous plexus bleeding, and proximal internal carotid artery aneurysm/pseudoaneurysm.
- Septodermoplasty may be necessary in stubborn cases of HHT.
- Care must be taken to avoid complications such as neuropraxia and septal perforation.
- Antibiotic use for nasal packing is controversial but may be recommended.
- Endovascular embolization is an alternative option for patients who are not suitable for SPA ligation.
- It requires collaboration with a radiologist and has a higher complication rate.
- The control rate is around 60-90% and there may be re-bleeding due to collateral arterial input.
- Complications include facial pain, trismus, amaurosis, ophthalmoplegia, embolic stroke, and death.
- Arteriography can help identify active bleeding for embolization.
- Embolization is used for maxillary artery posterior epistaxis.
- SPA ligation is the primary option for posterior epistaxis.
- Embolization is a secondary option if SPA ligation fails or is not suitable.
- Embolization involves blocking the blood vessels to stop bleeding.
- The procedure is performed by a radiologist.
