RESUMEN

An 88-year-old male underwent thoracic endovascular aortic repair (TEVAR) with the double-debranching and chimney technique for arch aortic aneurysm. When the aforementioned procedure was performed, the left common carotid artery was closed and transected, and the left subclavian artery was embolized and bypassed, respectively. However, postoperatively, the gutter endoleak persisted, and the aneurysm enlarged;therefore, requiring additional surgery. A skin incision was made on the left side of the neck, and the closed and dissected left common carotid artery stump was detected. A sheath was placed at the stump and an angiographic catheter and guidewire were used to retrograde cannulate the gutter beside the chimney graft, and coil embolization was performed. No endoleak was observed at postoperatively and 6-month follow up computed tomography( CT). We believe that embolization from a deblanched left common carotid artery stump is useful for endoleaks after TEVAR employing the chimney and debranching technique.

RESUMEN

BACKGROUND: Optimal contrast enhancement is crucial for the detection of coronary artery stenoses and atherosclerotic changes in coronary CT angiography (CTA). PURPOSE: To demonstrate the feasibility of using the cardiac output (CO) obtained from the test bolus injection data-set (COtest) as a factor in contrast injection rate revision of the following coronary CTA. MATERIAL AND METHODS: The test bolus injection data-sets of 52 consecutive coronary CTAs were examined. COtest was calculated from the test bolus data-set. Aortic peak enhancement (APE) was measured on the following coronary CTA. We simulated the APE at a fixed contrast injection rate of 4 mL/s (simAPE) in each patient. RESULTS: The ranges of COtest and simAPE were 2.82-7.56 L/min and 194-527 Hounsfield Units, respectively. There was a significant negative correlation (R = -0.802, P < 0.001) between simAPE and COtest. CONCLUSION: COtest can be used for injection rate revision on coronary CTA.
