Pseudoaneurysm of the lingual artery after concurrent intra‐arterial chemotherapy with radiotherapy for advanced tongue cancer

Abstract

Rupture of a pseudoaneurysm causes massive, life-threatening bleeding, which requires adequate diagnosis and treatment. Pseudoaneurysm should be considered in cases showing sudden oral bleeding after intra-arterial chemotherapy for advanced head and neck cancer.

Pathological and clinical impact of neoadjuvant chemoradiotherapy using full‐dose gemcitabine and concurrent radiation for resectable pancreatic cancer

“…Both cases had arterial pseudoaneurysm. Pseudoaneurysm related to radiotherapy is rare but occasionally life‐threatening [32, 33]. Therefore, postoperative caution and evaluation by imaging is required especially in patients treated with NACRT.…”

“…In patients who did not receive NACRT (non-NACRT group), the preoperative PNI was 47.6 ± 7.6 and had also significantly decreased at 6 months after surgery to 41.7 ± 8.1 (P \ 0.0001) cases had arterial pseudoaneurysm. Pseudoaneurysm related to radiotherapy is rare but occasionally life-threatening [32,33]. Therefore, postoperative caution and evaluation by imaging is required especially in patients treated with NACRT.…”

Embolization treatment of pseudoaneurysms originating from the external carotid artery

“…The causes PA from the ECA are varied but are most commonly associated with blunt or penetrating trauma. Other causes include iatrogenic origins, [7][8][9][10][11][12] inflammation, infection, vasculitis, tumor, and arteriosclerosis; however, there are also cases of unknown origins. 13 STA, IMA, and FA are the most common parent arteries of PA from the ECA because these are the vessels most susceptible to injury.…”

“…14,17,18 However, several complications may arise while waiting for spontaneous resolution. The size of the PA can increase gradually or abruptly, followed by the compression of nerves sufficiently to cause functional impairment, [19][20][21][22] which can eventually rupture and present as oral bleeding 9 or epistaxis. [23][24][25] The PA may also compress an adjacent vein, which can reduce venous outflow from the region causing distal embolization and thrombosis.…”

Pseudo-Aneurysm of Lingual Artery a Rare Complication of Squamous Cell Carcinoma of Tongue and a Cause of Oral Bleed

“…These require urgent hemostasis like clipping, ligation, embolization or ultrasound guided percutaneous thrombin [2]. Pseudo-aneurysm are those who lack the three layers of vessels wall which results from arterial damage [4]. They are differ from true aneurysm and composed of connective fibrous tissue results from leaking of blood through the damage wall into the adjacent fibrous connective tissue resulting in formation of blood clot that subsequently liquefies.…”
