Also, with an increase in incidence of MCA aneurysms, majorly at the M1 division point, actual standardized measurement of MCA is necessary. Thus, main aim of the study is assessment of the MCA morphometry using CT Angiography in Indian population.Methods: CT cerebral Angiography datasets of 289 patients (180 males and 109 females) were assessed for the MCA morphometry (Average age - 49.29 ± 16.16 years, Range- 11 to 85 years). The cases involving aneurysms and infarcts were excluded. The total length of MCA, length of M1 segment and diameter were measured and the results were statistically analysed.Results: The mean total length of MCA, length of M1 segment and diameter were 24.02 ± 1.22 mm, 14.32 ± 1.27 mm, 3.33 ± 0.62 mm, respectively. The mean length of M1 segment on the right and left sides was 14.19 ± 1.39 mm and 14.44 ± 1.12 mm, respectively and the difference was statistically significant (p ≤ 0.05). The mean diameter on the right and left sides was 3.32 ± 0.62 mm and 3.33 ± 0.62 mm, respectively and the difference was not statistically significant (p = 0.832). The M1 segment length was maximum in patients over 60 years and diameter was maximum in young patients (20-40 years). The mean length of M1 segment in early bifurcation (4.4 ± 0.65 mm), bifurcation (14.32 ± 1.27 mm) and trifurcation (14.15 ± 1.43 mm) was also noted.Conclusion: The MCA measurements will be useful for surgeons to minimize errors in handling cases of intracranial aneurysms or infarcts and provide the best possible outcome to the patients.","PeriodicalId":49296,"journal":{"name":"Surgical and Radiologic Anatomy","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9855775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PTA branched into the left distal SCA and showed segmental fusion with the proximal SCA at the distal part of the PTA. We also diagnosed an unruptured cerebral aneurysm at the junction between the left ICA and PTA.Discussion: PTA is the most frequent type of carotid-vertebrobasilar anastomosis. The reported prevalence rate is 0.2% by angiography and 0.34% by MR angiography. There are two types of PTA-lateral (usual) and medial (intrasellar). SCA arising from the lateral-type PTA has rarely been reported. Further, a PTA from which the distal SCA branches and segmentally fuses with the proximal SCA at the distal part of the PTA has not been reported.Conclusion: Using MR angiography, we diagnosed a rare type of PTA that fused segmentally with SCA.

A 60-years-old man with intraoral squamous cell carcinoma, initially treated with chemoradiation, developed osteoradionecrosis of his left mandible. The patient then underwent resection of this portion of the mandible with reconstruction by osteocutaneous fibular free flap with virtual surgical planning. During reconstructive planning for the resection and reconstruction, it was noted that the left internal and external jugular veins were absent, and a noteworthy compensatory internal jugular vein was present on the contralateral side. We report a rare case of this combination of anatomical variations within the jugular venous system.Conclusion: Unilateral agenesis of the internal jugular vein has been reported, but a combined variation with ipsilateral agenesis of the external jugular vein and compensatory enlargement of the contralateral internal jugular vein has, to our knowledge, not been reported on previously.

We also observed the detailed structure of the MC from the mental foramen to the mandibular foramen using cone-beam computed tomography (CBCT).Methods: In this study, mandibles from 45 sides of 23 human cadavers aged 76-104 years were examined by microscopy, immunohistochemistry, and CBCT analysis. These data were further evaluated by principal component analysis (PCA).Results: The microvessels of the vasa nervorum with calcitonin gene-related peptide- and neuropeptide Y-positive reactions were classified into 5 types: large (4.19%, 28/667); irregular large (7.35%, 49/667), numerous intermediate (29.23%, 195/667), irregular intermediate (29.23%, 195/667), and scattered fine (30.0%, 200/667) microvessels. The MC showed various structures from the 3rd molar to the premolars and was also classified into three types, including complete (57.0%, 228/400), partial (33.8%, 135/400), and unclear (9.2%, 37/400), from the mandibular foramen to the mental foramen. PCA results revealed that developed capillaries were mainly localized in the molar region.Conclusions: Fine microvessels of the vasa nervorum expressing neurotransmitters are present from the molar to premolar region, which is key information for mandibular dental treatments. The different microvessel structures also indicate differences in specific characteristics between dentulous and edentulous cadavers regarding oral surgical and implant treatments.","PeriodicalId":49296,"journal":{"name":"Surgical and Radiologic Anatomy","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9858706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An 81-year-old male was diagnosed with non-small cell lung cancer in S3 of the right upper lung. Preoperative three-dimensional computed tomography angiography revealed a B3 bronchus derived from the middle lobe bronchus and an anterior segmental pulmonary artery variation. Robot-assisted thoracoscopic surgery right upper lobectomy with ND2a-1 was performed via four-port incisions and an assist incision. No interlobar fissure was observed between the right upper and middle lobes. After dissecting B1+2, the displaced B3 root was dissected. The displaced A3a was difficult to dissect because of an extremely severe complete fissure. Therefore, we dissected the bronchus preceding from the cranial side. To confirm a minor fissure, indocyanine green was administered intravenously, and the interlobar boundary was identified as the line separating the dark and green lung parenchyma. The boundary was divided using mechanical staples. No surgical complications occurred.Conclusions: Using three-dimensional reconstruction imaging and systemic indocyanine green administration, we successfully performed a right upper lobectomy through robot-assisted thoracic surgery.","PeriodicalId":49296,"journal":{"name":"Surgical and Radiologic Anatomy","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10214538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to evaluate the variations and prevalence of celiac trunk (CeT) and its branches.Methods: The computerized tomography-angiography (CT-A) findings of 941 adult patients were evaluated retrospectively. Variations of the CeT and common hepatic artery (CHA) were evaluated according to the number of branches and their origin. Findings were compared with classical classification methods. A new classification model has been defined.Results: Normal (complete) trifurcation was detected in 856 (90.9%) of them, where left gastric artery (LGA), splenic artery (SpA) and CHA branches were derived from the CeT. Among 856 complete trifurcation cases, 773 (90.3%) had non-classical trifurcation patterns. The rate of classic trifurcation was 8.8%, while non-classic trifurcation was 82.1% in all cases. In one case (0.1%), LGA and left hepatic artery together and right hepatic artery and SpA together appeared as a double bifurcation. Complete celiacomesenteric trunk was observed only in 4 (0.42%) cases. In seven cases (0.7%), LGA, SpA and CHA were coming out of abdominal aorta (AAo) independently. CHA normal anatomy (Michels Type I) was detected in 618 (65.5%) patients. We found that 49 (5.2%) of our cases were ambiguous according to the Michels Classification. We have described five different variations of hepatic arteries directly arising from the AAo.Conclusion: Preoperative recognition of anatomical variations of CeT, superior mesenteric artery and CHA is of primary importance in both surgical and radiological procedures. With careful evaluation of CT-angiographies, it is possible to detect rare variations.","PeriodicalId":49296,"journal":{"name":"Surgical and Radiologic Anatomy","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9858197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
