Eur J Radiol 2024; 180:111705. [PMID: 39197271 DOI: 10.1016/j.ejrad.2024.111705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 07/22/2024] [Accepted: 08/23/2024] [Indexed: 09/01/2024]
Abstract
BACKGROUND AND PURPOSE Carotid blowout syndrome (CBS) is a potentially fatal disease. The CBS diagnosis mainly relies on subjective observations and the quantitative diagnotic method was not well established. This study aimed to diagnose CBS severity by computed tomography perfusion (CTP) parameters with different region-of-interest (ROI) models. MATERIALS AND METHOD We prospectively recruited CBS patients between February 1, 2018 and July 31, 2023 in a tertiary medical center, and CTP was performed using the same 128-detector CT machine. Digital subtraction angiography (DSA) and elective endovascular intervention were performed within 3 days post-CTP for diagnosis confirmation and treatments. CBS severity was classified into ongoing (threatened + impending) or acute CBS based on DSA findings and clinical features. Pericarotid soft-tissue (PCST) CTP parameters, including blood flow (BF), blood volume (BV), mean transit time (MTT) and flow extraction product (FEP), were evaluated and correlated on DSA. We depicted models A, B and C for the small focal lesion in 1 cm of PCST, 1 cm around PCST and the whole PCST respectively. RESULTS CTP images of 110 patients (77 ongoing (45 threatened + 32 impending); 33 acute) were analyzed. Pericarotid BV (1.8 ± 1.2vs.3.5 ± 2.0; p < 0.001) in Model A and BF in Model B (42.6 ± 11.0vs.50.9 ± 20.4; p = 0.031) were lower in acute-CBS than in ongoing-CBS patients. Subgroup analysis demonstrated lower BV in acute (1.8 ± 1.2) compared with threatened (3.7 ± 2.3; p < 0.001; p < 0.001) and impending (3.2 ± 1.6; p = 0.009) CBS patients in Model A. CONCLUSION CBS severity can be quantitatively diagnosed by pericarotid soft-tissue CTP parameters. In Model A (small focus), BV was capable of differentiating acute CBS from other subtypes, demonstrating its potential role as a CBS imaging biomarker.

[PMID: 38182115 DOI: 10.1016/j.ejvs.2023.12.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Revised: 12/04/2023] [Accepted: 12/30/2023] [Indexed: 01/07/2024]
Abstract
OBJECTIVE Lower neck cancers (LNCs) include specific tumour types and have some different vascular supply or collaterals from other head and neck cancers. This prospective study evaluated the outcome of endovascular management of post-irradiated carotid blowout syndrome (PCBS) in patients with LNC by comparing reconstructive management (RE) and deconstructive management (DE). METHODS This was a single centre, prospective cohort study. Patients with LNC complicated by PCBS between 2015 and 2021 were enrolled for RE or DE. RE was performed by stent graft placement covering the pathological lesion and preventive external carotid artery (ECA) embolisation without balloon test occlusion (BTO). DE was performed after successful BTO by permanent coil or adhesive agent embolisation of the internal carotid artery (ICA) and ECA to common carotid artery, or ICA occlusion alone if the pathological lesion was ICA only. Cross occlusion included the proximal and distal ends of the pathological lesion in all patients. Re-bleeding events, haemostatic period, and neurological complications were evaluated. RESULTS Fifty-nine patients (mean age 58.5 years; 56 male) were enrolled, including 28 patients undergoing RE and 31 patients undergoing DE. Three patients originally grouped to DE were transferred to RE owing to failed BTO. The results of RE vs. DE were as follows: rebleeding events, 13/28 (46%) vs. 10/31 (32%) (p = .27); haemostatic period, 9.4 ± 14.0 months vs. 14.2 ± 27.8 months (p = .59); neurological complication, 4/28 (14%) vs. 5/31 (16%) (p = .84); and survival time, 11.8 ± 14.6 months vs. 15.1 ± 27.5 months (p = .61). CONCLUSION No difference in rebleeding risk or neurological complications was observed between the DE and RE groups. RE could be used as a potential routine treatment for PCBS in patients with LNC.

Abstract
PURPOSE Carotid blowout syndrome (CBS) is a catastrophic complication of aggressive treatment of head and neck cancer. Early detection of bleeding points with embolization is a life-saving procedure; however, some bleeding points may be difficult to identify. Our aim was to determine whether guidewire manipulation (GWM) could be used to verify bleeding point locations in patients with CBS. METHODS Of the 92 patients with CBS referred for embolization in a 5-year period, 14 men and one woman (mean age 58 years) had bleeding points at locations that could not be definitely determined. We used GWM to verify the presence of these bleeding points. We assessed the anatomy of the ruptured arteries, technical details of GWM, and the angiographic and clinical outcomes. RESULTS Bleeding points were difficult to detect because of the presence of small arterial pouches (n = 6) or multiple small arterial pouches (n = 9) in the unilateral or bilateral carotid arteries. Bleeding point locations were accurately identified using GWM in the internal carotid artery (n = 7), carotid bulb (n = 4), or common carotid artery (n = 4). Balloon-assisted GWM was applied in one patient. Fiber coils (n = 15) and/or liquid adhesives (n = 2) were used to occlude the affected artery. Endovascular management was technically successful in all patients and resulted in immediate cessation of hemorrhage without recurrence in a mean 22-month clinical follow-up. CONCLUSION GWM is a simple and effective method for verifying bleeding points in ruptured arteries and preventing erroneous occlusion by embolization.

Abstract
Case A 70-year-old man was brought to our hospital emergency department with accidental thermal burns. Surgical tracheostomy was carried out on day 8 after admission, followed by several profuse bleeding episodes from the orifice. Contrast-enhanced computed tomography of the neck revealed a small nodule with arterial phase enhancement that was suspected to be a pseudoaneurysm. During emergency angiography, the nodule was revealed to be a pseudoaneurysm arising from the right superior thyroid artery with contrast medium extravasation. Outcome The patient underwent transcatheter arterial embolization, which resolved bleeding from the tracheostomy orifice. Conclusion Pseudoaneurysm of the superior thyroid artery is an extremely rare and life-threatening tracheostomy complication. All clinicians certified to perform tracheostomy should be acquainted with the various complications and methods for managing life-threatening post-tracheostomy complications.

Abstract
OBJECTIVES Endovascular treatment is effective in treating carotid blowout syndrome (CBS). We reviewed our experience in addressing CBS over eight years and presented an account of the treatment paradigm and management algorithm. METHOD All cases of CBS from 2003 to 2010 with endovascular treatment performed in our center were reviewed. 15 CBS in 14 patients were recruited. Based on our management algorithm, treatment regimen was stratified into deconstructive or constructive methods. Their clinical presentations, angiographic features, angiographic and clinical outcomes were reviewed. RESULTS 10 patients were treated with deconstructive method by means of permanent vessel occlusion (PVO) and 4 patients were treated with constructive method by means of placement of covered stent (n=3) or flow diverting device (n=1). Immediate hemostasis was achieved in all cases. 7 (50%) patients, in whom 5 treated with PVO and 2 with covered stent, had favorable outcomes and survived at a median follow-up period of 4 months (range: 1-84 months). CONCLUSION Permanent vessel occlusion remains the gold standard of treatment and tends to show a favorable long-term outcome. Off-label use of covered stent and flow-diverting device can produce satisfactory results should balloon occlusion test fail, but long-term follow up would be required for definitive assessment.
