Abstract Background: Superb micro-vascular imaging (SMI) provided new advances in vascular imaging, resulting in revealing the overall vascularity detection of small or microflow states without the use of contrast media. This study aimed to explore the blood supply andfeeding artery of carotid body tumor (CBT) on SMI for providing more accurate information for surgery.Results: Twenty-six CBT lesions underwent color Doppler flow imaging (CDFI) and SMI, and were confirmed later by pathology. The blood flow patterns and feeding artery of CBTson CDFI and SMI were graded and compared.Compared with the application of CDFI, the pattern of more CBT lesionschanged to a higher Adler category by SMI (P<0.001). Thefeeding artery of two CBT lesions, which fail to show by CDFI, was internal carotid artery(ICA) by SMI and compared with CDFI the feeding artery of three changed from ICA or external carotid artery(ECA) to MIX (both ICA and ECA) by SMI. We classified the feeding artery of CBTs into originating from ICA or others (including ECA and MIX). For all the lesions, threelesions that stemmed from ICA and 23lesions that stemmed from ECAor MIX. CBT lesions stemming from ECA or MIX with Adler II or Adler III blood flow patterns accounted for 30.4% (7/23) or 69.6% (16/23), respectively, while CBT lesions stemming from ICA with Adler I or Adler II blood flow patterns accounted for 66.7% (2/3) or 33.3% (1/3), respectively. Conclusions: SMI is superior to CDFI in detecting vascularity of CBTs, and SMI could better investigate the origin of feeding vessels of CBTs in comparison to CDFI.Compared with those originating from ECA, CBTs from ICA has less vascularity.

Benign Mass

A carotid body tumor is typically a benign mass and can have a low malignant potential. It can grow in between, attach to, or surround the internal carotid artery and external carotid artery in the neck. If this mass grows too big, it can compress the two arteries, causing problems in getting blood flow to the brain. The purpose for this sonography examination was to evaluate a patient with the following symptoms: dizziness, facial nerve injury, and sensorineural hearing loss. The carotid body tumor is a highly vascular tumor. This sonography examination provides a good opportunity to teach the importance of the use of color Doppler and proper documentation of this pathology that is often incorrectly documented with improper settings. This case reviews a 69-year-old Caucasian male with a carotid body tumor. The sonographic features, prevalence, common symptoms, prognosis, and treatments of the carotid body tumor are reviewed.

The Relationship

Objective: Patients with internal carotid artery (ICA) occlusion or severe stenosis usually have collateral via ophthalmic artery (OA). However, the relationship of blood flow patterns of OA and the degree of ICA stenosis has been rarely reported. Transcranial Doppler (TCD) is a promising modality to assess OA collateral when ICA lesion. Considered OA characteristics including tortuosity and anatomical variations, we try to evaluate the supraorbital artery (SA), the one of OA terminal branches, to analyze the relationship of flow with the degree of ICA stenosis. Materials and Methods: From Jun 2012 to Jan 2015, TCD were performed to 40 patients with ICA stenosis before and after carotid artery stenting (CAS). SA blood flow patterns were compared with the degree of ICA stenosis confirmed by conventional angiography. Results: 40 patients (29 men) were enrolled (mean age 64.9 yrs). Before CAS, the retrograde blood of SA was found in 40 patients. After stenting, the flow pattern reversed in 29 patients of these patients (29/40, 72.5%). The blood flow of SA was gradually reverse over time from angioplasty with balloon to several days after CAS. The patterns of these changes were categorized into four types: (A), flow spectrum completely reversed; (B), reverse flow spectrum associated with systolic notch; (C), flow spectrum forward at systolic and reverse at diastolic; (D), type flow spectrum entirely forward. Before balloon angioplasty (mean stenosis, 93.4%), A type was found in 39 of them, B type in 1 patient; after balloon dilatation (mean stenosis, 82.9%), 26 A types and 4 B, 5 C, 5 D types. Stent (mean stenosis, 14.9%), 1 A type, 4 B and 4 C, 29 D types. Conclusion: The flood flow patterns of SA may be associated with the degree of carotid stenosis evaluated with TCD and the blood flow may be reverse after CAS.

Objectives Though carotid body tumors are rare, increasing attentions have been given because of malignant transformation and high surgical risk. However, at present, the characteristics and etiology still remain unclear. Our study was designed to describe the clinical features of carotid body tumors in our institution and to compare the results with previous reports. Methods We retrospectively reviewed carotid body tumor patients diagnosed in our institution from January 2015 to May 2020. The demographics, comorbidities, lesion location, anatomic characteristics, complications, and postoperative outcomes were evaluated. Carotid body tumor measurements were determined from computed tomography, magnetic resonance imaging, and carotid arteriography examination. We described and compared the clinical features of carotid body tumors in our institution and other reports. Results We totally identified 122 carotid body tumor cases for the present analysis. The mean age was 50.26 years, with the majority being female (82%). The commonest presentation was a painless neck mass (68%). For the distribution of nationality, most patients were the Han nationality (69.7%). The mean altitude of habitat of patients was 2689.4 km; 19.7% patients suffered bilateral lesions. The main blood supply of carotid body tumors was from external carotid artery (54.1%). For patients who received operation, 11 (11.2%) patients experienced cranial nerve injury. The maximal diameter of tumors was 3.99 ± 1.98 cm in male and 3.38 ± 1.36 cm in female. The volume of tumors was 31.49 ± 29.76 cm3 in male and 15.27 ± 13.06 cm3 in female. The distance to base of skull of tumors was 3.39 ± 1.07 cm (3.99 ± 1.98 cm in male vs 3.38 ± 1.36 cm, P <  0.05). Two patients (2.04%) were identified as having malignant carotid body tumor. Conclusions Though carotid body tumor had a low morbidity and multitudinous clinicopathologic features, it was apt to middle-aged women and the main blood supply was from external carotid artery. The painless neck mass was the commonest presentation of carotid body tumors. There were significant difference between male and female patients regarding platelet, hemoglobin, distance to base of skull, tumor volume, altitude of habitat, carotid body tumor location, and hypertension.
