The common causes of nosebleeds with very large viscous blood clots are dry rhinitis combined with hypertension, ruptured nasal capillary hemangioma, maxillary sinus hemorrhage necrotizing nasal polyps and other diseases.
1. Dry rhinitis combined with hypertension: dry rhinitis patients with thin nasal mucosa, vascular fragility. When the blood pressure fluctuates drastically in patients with hypertension, it can lead to extensive capillary rupture and bleeding of nasal mucosa, which is mostly venous hemorrhage, the blood flow rate is not fast, and the blood accumulates due to the extracorporeal coagulation mechanism, which forms a large viscous blood clot.
2. Rupture of nasal capillary hemangioma: when bleeding from the anterior and inferior part of the nasal septum, there may be a very large viscous blood clot. This is because this part is not only the impact point of airflow impacting the nasal cavity, but also the intersection of static and dynamic blood vessels in the nasal cavity. Once this part of the bleeding, the bleeding will be very large, and may be static artery damage at the same time, the occurrence of extracorporeal coagulation can be seen after the manifestation of a very large viscous blood clots.
3. maxillary sinus hemorrhage necrotizing nasal polyps: this disease in the blood vessel rupture can have a large number and violent nosebleed, blood and nasal mucopurulent secretion mixed, because purulent secretion is generally colloidal, and blood mixed together, forming a very large viscous blood clots.
It is recommended to go to the hospital to find out the cause of the nosebleed with a large viscous blood clot.
