CT angiogram head sagittal - labelling questions

Medical science says that ischemia is a common complication in Diabetes, especially in the lower limb but this is a case presenting ischemic changes in upper limb which is unique and also in such type of acute ischemia amputation is the only choice of treatment to save the life of patient from septicaemia. Such a rare and interesting case was taken at Sri Sri Ayurveda Hospital and handled by proper Ayurvedic line of treatment by which circulation is re-established which saved both limb and life of patient. A patient by name Sundaramma, 62yr Female, visited Sri Sri Ayurveda Hospital on 29/2/2016 with a diagnosis of Right upper limb Ischemia with Diabetes Mellitus and Active TB. The main symptoms were severe pain and burning sensation in Right hand and forearm, discolouration of fingers with ulcers, Bluish black discolouration over right thumb, necrosis, pus dischargeand stiffness, associated with difficulty in movement of right arm, shoulder joint, elbow joint, palm and fingers. Diagnosed as Right Upper Limb Ischemia with Diabetes Mellitus and active TB. Therapeutic interventions like Right upper limb Doppler and CT angiogram were done. Such a complicated case was taken at Sri Sri Ayurveda Hospital, and carefully handled by Ayurvedic methods of management, which was ended up by preventing amputation of the limb and also achieving the re-establishment of arterial circulation.

Abstract Despite technological advances in endovascular therapy, surgical clipping of paraclinoid aneurysms remains an indispensable treatment option and has an acceptable profile risk. Intraoperative monitoring of motor and somatosensory evoked potentials has proven to be an effective tool in predicting and preventing postoperative motor deficits during aneurysm clipping.1,2 We describe the case of a 61-yr-old Japanese woman with a history of hypertension and smoking. During follow-up for bilateral aneurysms of ophthalmic segment of the internal carotid artery (ICA), left-sided aneurysm growth was detected. A standard pterional approach with extradural clinoidectomy was used to approach the aneurysm. After clipping, a significant intraprocedural change in motor evoked potential (MEP) amplitude was observed despite native vessel patency was confirmed through micro-Doppler and indocyanine green video angiography.3-5 After extensive dissection of the sylvian fissure and exposure of the communicating segment of ICA, the anterior choroidal artery was found to be compressed and occluded by the posterior clinoid because of an inadvertent shift of the ICA after clip application and removal of brain retractors. Posterior clinoidectomy was performed intradurally with microrongeur and MEP amplitude returned readily to baseline values. Computed tomography (CT) angiogram demonstrated complete exclusion of the aneurysm, and magnetic resonance imaging (MRI) was negative for postoperative ischemic lesions on diffusion weighted images. The patient tolerated the procedure well and was discharged home on postoperative day 3 with modified Rankin Scale (mRS) 0. The patient signed the Institutional Consent Form to undergo the surgical procedure and to allow the use of her images and videos for any type of medical publications.

Abstract An 8-day-old neonate was presented with severe respiratory distress and diagnosed as primary pulmonary hypertension of the newborn on functional echocardiogram. Evaluation showed bounding pulse, enlarged umbilical cord, and bruit over the periumbilical region. Transthoracic echocardiography and CT angiogram showed a large fistulous communication between the umbilical vein and artery suggestive of congenital umbilical arteriovenous malformation leading to high-output cardiac failure and pulmonary artery hypertension. The patient was stabilised with medications and ventilation. Transcatheter closure of communication was done using coils, vascular plug, and KONAR-MFTM device. The patient improved from heart failure soon after the procedure and thriving normally at 6 months of follow-up.

Vessel Thrombosis

SARS-CoV-2 has proven its versatility in host presentations; one such presentation is a hypercoagulable state causing large-vessel thrombosis. We report a case on a previously asymptomatic COVID-19-positive patient presenting with an acute ischaemic stroke and an incidental left internal carotid artery thrombus. The patient’s medical, social and family history and hypercoagulability screening excluded any other explanation for the left carotid thrombus or stroke, except for testing positive for the COVID-19. This case explores the known hypercoagulable state associated with COVID-19 and the effect of the virus on the host’s immune response. It also questions whether administration of recombinant tissue plasminogen activator (t-PA), according to the American Heart Association guidelines, following a negative head CT for haemorrhagic stroke is safe without prior extended imaging in this patient population. We recommend, in addition to obtaining a non-contrast CT scan of the brain, a CT angiogram or carotid duplex of the neck be obtained routinely in patients with COVID-19 exhibiting stroke symptoms before t-PA administration as the effects may be detrimental. This recommendation will likely prevent fragmentation and embolisation of an undetected carotid thrombus.

Abstract Introduction Lower gastrointestinal bleeding (LGIB) accounts for 3% of all surgical referrals in the UK, with an in-hospital mortality of 3.4%. The BSG 2019 guidelines recommend risk stratification as per Oakland scoring, inpatient lower GI endoscopy for admissions and CT-angiography for unstable patients. This study evaluates the delivery of these outcomes in a district hospital setting. Method Retrospective audit assessing all acute LGI bleed admissions from 01-07-2019 to 28-02-2020 at Russells Hall Hospital. Shock Index (SI) and Oakland score used to stratify patients into unstable, stable-major and stable-minor LGIB. Compliance with BSG standards was assessed by review of investigations and emergent patient management. Results 143 patients (Median age = 70years) evaluated, with 64 admissions having no formal risk stratification (OAKLAND-score) documented. Only 12 admissions underwent inpatient LGI endoscopy with sigmoid diverticulosis the most common pathology (39.3%). CT-angiogram was the initial investigation for 75% of patients admitted with unstable LGIB. Conclusions OAKLAND-scoring is a sensitive tool to stratify LGIB patients based on clinical parameters. Application of BSG-2019 guidelines and developing consistency in management is challenged by the lack of routine access to LGI endoscopy and tools to manage bleeding endoscopically.

Abstract Background/Aims Giant cell arteritis with large vessel vasculitis (LV-GCA) represents a distinct, less researched sub-category of giant cell arteritis (GCA). In comparison to cranial GCA, the patient’s diagnostic pathway is less well described and it is thought that LV-GCA is underdiagnosed, including in patients with polymyalgia rheumatica and cranial-GCA. Advances in imaging (e.g. PET-CT) and treatment (tocilizumab), have provided additional options in the diagnosis and management of LV-GCA. The aim was to describe the contemporary clinical journey for patients diagnosed with LV-GCA. Methods The electronic patient health record system in NHS Lothian (TrakCare) was used to collect relevant data. Patients with imaging-confirmed large vessel vasculitis, diagnosed with GCA after 1 January 2017 were included. Follow-up was until August 2020. Results Eighteen patients with LV-GCA were included. The mean age was 65 years and 66.7% were female. Two patients had known cranial-GCA but 89% of patients were diagnosed exclusively with large vessel involvement. The most common symptoms were malaise (55%), weight loss (55%), polymyalgia rheumatica (55%) and limb claudication (44%). Pyrexia of unknown origin was a feature in only 17% of patients. Two patients were asymptomatic and were investigated on the basis of raised inflammatory markers. Mean CRP at baseline was 99mg/L and ESR 85mm/hour. The mean time from symptom-onset to diagnosis was 6.8 months (range 1 to 15 months). Sixteen patients (89%) were reviewed by at least one other secondary care specialist. One third of patients were referred from General Medicine followed by Vascular Surgery (16%) and General Practice (16%). 7/18 patients were inpatients at the time of referral. 56% of patients required two modalities of imaging to confirm large vessel involvement. The most commonly used imaging techniques (in descending order) were CT-Chest/Abdomen/Pelvis, CT-angiogram, PET-CT and Vascular Ultrasound. 50% of patients underwent follow-up imaging, most commonly MR- or CT-angiography. Mean follow-up was for 1.6 years. The mean prednisolone dose at 3 months (n = 18) was 24mg daily and 8mg at 12 months (n = 12). 28% of patients relapsed during the follow-up period at 4, 5, 8, 9 and 24 months post-diagnosis. 7/18 patients were commenced on methotrexate for steroid-side effects or for relapse. 8/18 received subcutaneous tocilizumab in combination with methotrexate in two cases. Three patients were started on azathioprine but only one continued. Conclusion In modern-day clinical practice, patients with LV-GCA experience a longer time to diagnosis than those with cranial symptoms. Patients with LV-GCA can experience an array of constitutional symptoms. Frequently, more than one imaging modality is required to confirm LV-GCA and the majority of patients will have seen other hospital specialists or have been admitted to hospital before diagnosis. Methotrexate and tocilizumab are the most frequently-used and effective steroid-adjunct in this single-centre cohort. Disclosure O. Cronin: None. N.D. McKay: Consultancies; Gilead.

A 29-year-old man arrived in our emergency department after being shot on the face. Computed tomography (CT) revealed multiple facial bone fractures along the bullet trajectory. On day 10 of admission, CT angiogram of the neck revealed a partially thrombosed pseudoaneurysm in the parapharyngeal fat pad. The pseudoaneurysm was successfully treated with coil embolization. This report discusses diagnosis and treatment of a partially thrombosed internal maxillary artery pseudoaneurysm. Although digital subtraction angiography is the gold standard for pseudoaneurysm diagnosis, CT angiography may provide complimentary information, as seen in this case.

Graft Positioning

The technique is demonstrated in a 78-year-old man; the preoperative CT angiogram showed a descending thoracic aorta ulcer of 5.9 cm in maximum diameter and 3.8 cm longitudinal extension. A ZTEG-2P-36-127-PF (Cook Medical) single tubular endograft was planned to be deployed. From the preoperative CT angiogram we planned to land 4.7 cm above the midline of the descending thoracic aorta ulcer and 8.0 cm below. In the operating room, under radioscopic vision the centre of the transesophageal echography probe was used as marker to identify the correspondent midline of the descending thoracic aorta ulcer and a centimeter-sized pigtail catheter in the aorta was used to calculate the desired length above and below the ulcer midline. The endograft was introduced and placed in the desired position compared to the transesophageal echography probe and the catheter; under transesophageal echography vision the graft was finally deployed. The CT angiogram at 1 month showed the correct endograft position, descending thoracic aorta ulcer exclusion with no signs of endoleak. In selected cases, this method allows planning in advance safe stent graft positioning and deployment totally assisted by transesophageal echography, with no risk of periprocedural contrast-related renal failure and reduced radiation exposure for the patient and operators.

Work Up

BACKGROUND AND PURPOSE: To determine whether Perfusion-CT (PCT) adds value to Noncontrast head CT (NCT), CT-Angiogram (CTA) and clinical assessment in patients suspected of acute ischemic stroke. METHODS: We retrospectively reviewed the clinical and imaging data collected in 165 patients with acute ischemic stroke. ASPECTS score was calculated from NCT. CTA was reviewed for site of occlusion and collateral flow score. PCT was used to calculate the volumes of infarct core and ischemic penumbra on admission. Recanalization status was assessed on follow-up imaging. Clinical data included age, time from onset to baseline imaging, time from baseline imaging to reperfusion therapy, time from baseline imaging to recanalization imaging, NIHSS at baseline, treatment type and modified Rankin score (mRS) at 90 days. In a first multivariate regression analysis, we used volume of PCT penumbra and infarct core as outcome, and assessed whether they could be predicted from clinical variables, NCT and/or CTA. In a second multivariate regression analysis, we used mRS at 90 days as outcome, and determined which imaging and clinical variables predicted it best. RESULTS: 165 patients were identified. Mean±SD time from onset to baseline imaging was 6.7±8.7 hrs. 76 had a good outcome (90-day mRS 0-2), 89 had a poor outcome. Mean±SD PCT infarct was 44.8±46.5 ml. Mean±SD PCT penumbra was 47.0±33.9 ml. PCT infarct could be predicted by clinical data, NCT, CTA, and combinations of this data (P<0.05); the best predictive model included the clinical data, plus NCT and CTA. PCT Penumbra could NOT be predicted by clinical data, NCT, and CTA. In terms of predicting mRS at 90 days, all of variables but NCT and CTA were significantly associated with 90-day mRS outcome. The single most important predictor was recanalization status (P<0.001). PCT penumbra volume (P=0.001) was also a predictor of clinical outcome, especially when considered in conjunction with recanalization through an interaction term (P<0.001). CONCLUSION: PCT penumbra represents independent information, which cannot be predicted by clinical, NCT, and CTA data. PCT penumbra is an important determinant of clinical outcome, and adds relevant clinical information compared to a stroke CT work-up including NCT and CTA.
