The Great Contrast Shortage of 2022 —Lessons learnt in Australia
ConclusionOur findings demonstrate that the IBCM shortage crisis had a very significant impact on the delivery of healthcare. While V/Q scans could (partially) substitute for CTPA studies in suspected pulmonary emboli, there appeared to be no valid alternative for CTNA studies in stroke calls. The unexpected and critical shortage of IBCM forced healthcare professionals to conserve resources, prioritise indications, triage patients based on risk, explore alternate imaging strategies and prepare for similar events recurring in the future.

Identifying ex vivo acute ischemic stroke thrombus composition using electrochemical impedance spectroscopy
CONCLUSION: Combination of EIS and machine learning can reliably predict the RBC composition of retrieved ex vivo AIS thrombi and then classify them into groups according to their RBC composition with good sensitivity and specificity.PMID:37192738 | DOI:10.1177/15910199231175377

Stroke Thrombectomy through Interstices of a Hybrid Endograft Placed for Type A Aortic Dissection
A 53-year-old man presented with acute, severe, thoracic pain, absence of the femoral and left radial pulses, and asymmetric blood pressure —80/40 mm Hg in the left arm and 170/110 mm Hg in the right arm. Contrast-enhanced computed tomography revealed type A aortic dissection, starting from the aortic valve and extending into both iliac arteries (Fig 1). Emergent hemiarch replacement surgery was performed, with insertion of a hybrid a ortic stent with a proximal felt sewing cuff (Ascyrus Medical Dissection Stent, [AMDS]; Ascyrus Medical, Frankfurt, Germany) into the aortic arch with reimplantation of the brachiocephalic ...

Identification of vulnerable carotid plaque with histologically validated CT-derived plaque maps
CONCLUSIONS: Carotid plaque components can be differentiated by CT using a ratio of plaque/contrast attenuation. CT-derived plaque map volumes of necrotic core help distinguished the most vulnerable plaques.ADVANCES IN KNOWLEDGE: CT-derived plaque maps based on plaque/contrast attenuation may provide new markers of carotid plaque vulnerability.PMID:37183910 | DOI:10.1259/bjr.20220982

Safety and Efficacy of Baseline Antiplatelet Treatment in Patients Undergoing Mechanical Thrombectomy for Ischemic Stroke
Baseline use of antiplatelet medication before mechanical thrombectomy (MT) for acute ischemic stroke (AIS) can provide benefit on reperfusion and clinical outcome, but could also carry an increased risk of intracranial hemorrhage (ICH). This nationwide study investigates the safety and efficacy of baseline antiplatelet treatment in AIS patients undergoing MT.

Impact on etiology diagnosis by high-resolution vessel wall imaging in young adults with ischemic stroke or transient ischemic attack
ConclusionsHRVWI had a substantial impact on etiologic classification in young adults with ischemic stroke or TIA, particularly for those primarily classified as having SAO or SUE. This impact of HRVWI will be beneficial for therapeutic decision-making.

MRI for collateral assessment pre-thrombectomy and association with outcome: a systematic review and meta-analysis
ConclusionIn stroke patients treated with thrombectomy, good pre-treatment collaterals assessed using MRI are associated with double the rate of functional independence. However, we found evidence that relevant MR methods are heterogenous and under-reported. Greater standardization and clinical validation of MRI for collateral evaluation pre-thrombectomy are required.
