An unusual case of situs inversus was observed during routine postmortem of a 60 year old male subject at Government medicalcollege, Amritsar, Punjab, India. On the right side the common carotid artery was found to be absent. The right external carotid artery arosedirectly from the arch of aorta. The left internal carotid artery had a wide diameter and bifurcated . The right subdivision crossed overcompensating for absent right internal carotid artery. The compensation of absent internal carotid artery in situs inversus makes present caseunique and such variation has thus far never been reported in literature.The ontogeny and clinical implications of the variation have beendiscussed.

Abstract Objective: Access to the high cervical internal carotid artery (ICA) is technically challenging for the treatment of lesions in and around this region. The aims of this study were to analyze the efficacy of approaching the high cervical ICA through the retromandibular fossa and to compare preauricular and postauricular incisions. In addition, the relevant neural and vascular structures of this region are demonstrated in cadaveric dissections. Methods: The retromandibular fossa approach was performed in four arterial and venous latex-injected cadaveric heads and necks (eight sides) via preauricular and postauricular incisions. This approach included three steps: 1) sternocleidomastoid muscle dissection; 2) transparotid dissection; and 3) removal of the styloid apparatus and opening of the retromandibular fossa to expose the cervical ICA with the internal jugular vein along with Cranial Nerves X, XI, and XII. Results: The posterior belly of the digastric muscle and the styloid muscles were the main obstacles to reaching the high cervical ICA. The high cervical ICA was successfully exposed through the retromandibular fossa in all specimens. In all specimens, the cervical ICA exhibited an S-shaped curve in the retromandibular fossa. The external carotid artery was located more superficially than the ICA in all specimens. The average length of the ICA in the retromandibular fossa was 6.8 cm. Conclusion: The entire cervical ICA can be exposed via the retromandibular fossa approach without neural and vascular injury by use of meticulous dissection and good anatomic knowledge. Mandibulotomy is not necessary for adequate visualization of the high cervical ICA.

Purpose Neurologic determination of death or brain death is primarily a clinical diagnosis. This must respect all guarantees required by law and should be determined early to avoid unnecessary treatment and allow organ harvesting for transplantation. Ancillary testing is used in situations in which clinical assessment is impossible or confounded by other factors. Our purpose is to determine the utility of dynamic computed tomographic angiography (dCTA) as an ancillary test for diagnosis of brain death. Materials and Methods We retrospectively reviewed 13 consecutive patients with suspected brain death in the intensive care unit who had dCTA. Contrast appearance timings recorded from the dCTA data were compared to findings from 15 controls selected from patients who presented with symptoms of acute stroke but showed no stroke in follow-up imaging. Results The dCTA allows us to reliably assess cerebral blood flow and to record time of individual cerebral vessels opacification. It also helps us to assess the intracranial flow qualitatively against the flow in extracranial vessels as a reference. We compared the time difference between enhancement of the external and internal carotid arteries and branches. In all patients who were brain dead, internal carotid artery enhancement was delayed, which occurred after external carotid artery branches were opacified. Conclusion In patients with suspected brain death, dCTA reliably demonstrated the lack of cerebral blood flow, with extracranial circulation as an internal reference. Our initial results suggest that inversion of time of contrast appearance between internal carotid artery and external carotid artery branches at the skull base could predict a lack of distal intracranial flow.

ABSTRACTIntroductionTransradial angiography (TRA) has received considerable attention in the field of neurointervention owing to its advantages over transfemoral approaches. However, the difficulty of left internal carotid artery (ICA) catheterization under certain anatomical conditions of the aortic arch and its branches is a limitation of TRA. This study aimed to investigate the anatomical predictors of successful catheterization of the left ICA in TRA.Materials and MethodsFrom January 2020 to October 2020, 640 patients underwent TRA at a single institute. Among them, 263 consecutive patients who were evaluated by contrast-enhanced MRI before TRA were included in our study and assigned to success and failure groups, according to whether left ICA catheterization was possible or not. Anatomical predictors that may affect the success of left ICA catheterization in TRA were investigated for the purposes of our study.ResultsThe multivariable analysis included variables that demonstrated significant univariate associations with ICA catherization (P<0.0001). Variables included in the model were the type of aortic arch, height of right subclavian artery, turn-off angle of the left common carotid artery (CCA), distance between innominate artery to the left CCA, angulation of right subclavian artery, and angulation of the left CCA, which we identified as significant predictors of left ICA catheterization.ConclusionSuccess of left ICA catheterization in TRA was related to the vascular geometry of the aortic arch and its branches. Evaluating the anatomical predictors identified in this study using pre-procedure imaging may enhance the success rate of left ICA catheterization in TRA.
