“…Complication rate in endoscopic sinus surgery is reported to be in the range of 4%–22.4% 2. Most of these complications are minor; however, major complications such as cerebrospinal fluid leak, meningitis and haemorrhage are known to occur 3. A majority of bleeding that occurs in such cases is from small vessels and arterioles in the area of Kiesselbach and does not require aggressive intervention.…”

Endovascular management of a sphenopalatine artery pseudoaneurysm: a rare cause of delayed intractable epistaxis following endoscopic transsphenoidal pituitary surgery

et al. 2023

Vascular injuries during pituitary surgery are feared as they can lead to serious disability and can be life threatening. We are describing a case of severe intractable epistaxis following endoscopic transnasal transsphenoidal surgery for pituitary tumour due to a sphenopalatine artery pseudoaneurysm which was successfully managed using endovascular embolisation techniques. Very few cases of sphenopalatine artery pseudoaneurysm following endoscopic nasal surgery have been described. A middle aged male patient with a pituitary macroadenoma underwent endoscopic transsphenoidal pituitary surgery and returned to us after 3 days of discharge with severe epistaxis. Digital subtraction angiography showed contrast leakage and left sphenopalatine artery pseudoaneurysm. Glue embolisation of the distal sphenopalatine branches and pseudoaneurysm was done. Good occlusion of pseudoaneurysm was seen. Such a diagnosis for epistaxis following endoscopic transnasal surgery should be borne in mind, so prompt treatment can be planned to avoid life threatening complications.

“…In review of the literature, the pseudoaneurysms occurred following a postoperative delay of 2 days to 4 months (Table 1 ). 6 – 9 Previous patients required a transfusion or even resuscitation, due to delayed massive bleeding. It is clinically significant that we did not require a transfusion despite encountering uncontrolled massive bleeding after the compact nasal packing, since we immediately performed an intervention procedure.…”

“… 4 , 5 A review of the literature showed that the occurrence of pseudoaneurysm due to severe postoperative bleeding after endoscopic sinus surgery (ESS) has been reported in 4 patients. 6 – 9 In contrast to these patients, we recently encountered a pseudoaneurysm in the internal maxillary artery (IMA) after ESS, which was immediately and successfully treated by endovascular embolization. Therefore, we decided to report this patient and review the literature.…”

Pseudoaneurysm is defined as blood leaking out of a vessel that does not have true 3 arterial walls like a true aneurysm, and is susceptible to rupture. Only 4 patients of pseudoaneurysm after endoscopic sinus surgery have been reported so far in English literature. Recently, the authors encountered a pseudoaneurysm in the internal maxillary artery after endoscopic sinus surgery, which was immediately and successfully managed with endovascular embolization. There was no bleeding or complications 6 months after the embolization.

“…There are reports of sphenopalatine artery pseudoaneurysms having occurred postoperatively after endoscopic sinus surgery and orthognatic surgery (notably Le Fort I osteotomy) as well as post-traumatically. [6281216] Bleeding from the sphenopalatine artery, as from other branches of the external carotid artery, has been reported to have been successfully attenuated using detachable balloons, N-butyl-2-cyanoacrylate, particles, and platinum coils.

Background:Vascular injuries in transsphenoidal surgery for pituitary adenomas are uncommon but can result in serious disability or death.Case Description:A 46-year-old man, who underwent resection of a pituitary adenoma with suprasellar extension via a transsphenoidal approach, presented with massive epistaxis five days postoperatively. Angiography revealed an arteriovenous fistula (AVF) between the right sphenopalatine artery and a deep vein draining to the right internal jugular vein, as well as contrast agent extravasation at the fistula point. The AVF was catheterized and successfully occluded with N-butyl-2-cyanoacrylate.Conclusions:Transsphenoidal pituitary surgery can be complicated by massive epistaxis from a lesion of a small branch of the external carotid artery. Airway protection through intubation and investigation with conventional digital subtraction angiography is recommended. The treatment of choice is endovascular embolization because it can be done immediately at the angiography suite.
