CT imaging findings and endovascular management of isolated spontaneous dissecting aneurysm of celiac artery

Objective: COVID-19 has been detected in Turkey since March 11, 2020. Istanbul has become an important center of the pandemic in Turkey. Various risk factors for COVID-19 infection, mortality, and morbidity are under investigation. Recent studies have suggested that certain blood groups are risk factors for the disease. The aim of this study is the evaluation the relationship between blood groups and the risk of contracting COVID-19 disease, clinical severity of the disease, and CT (computed tomography) imaging findings. Material and Methods: Age, gender, blood group data, clinical severity and CT images of 300 patients who were positive with RT PCR (Reverse transcription-polymerase chain reaction) and were followed up in the clinic were retrospectively scanned and recorded. The clinical severity of the disease and CT imaging findings were scored, and the data were evaluated statistically. Results: While the incidence of COVID-19 was high in the A blood group, it was low in the 0 blood group. Although there was no significant difference between blood types and clinical severity, the involvement in the B blood group was more severe on CT imaging. Conclusion: People with A blood group should pay more attention to protection and isolation. Investigating this difference and underlying pathogenic mechanisms can guide science with advanced studies.

Safety And Efficacy

Purpose: Thoracic endovascular aortic aneurysm repair (TEVAR) has emerged as an attractive alternative option in the treatment of thoracoabdominal aortic aneurysm (TAAA) diseases, reporting lower morbidity and mortality rates compared with open or hybrid repair. A challenging situation arises when the aneurysm involves the celiac artery (CA), precluding a safe distal landing zone. We investigated the safety and efficacy of CA coverage in the treatment of complex TAAA diseases during endovascular management. Materials and Methods: A review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The electronic bibliographic sources searched were MEDLINE and SCOPUS databases. Primary outcomes of interest were perioperative and 30-day mortality. Any type of endoleak, mesenteric ischemia, perioperative spinal cord ischemia, and reintervention rates were secondary end points. A random-effects meta-analysis was performed. Summary statistics of event risks were expressed as proportions and 95% confidence interval (CI). Results: Ten observational cohort studies published between 2009 and 2020, reporting a total of 175 patients, were eligible for quantitative synthesis. Indications for TEVAR were primary TAAAs in 82% of patients, aortic dissection in 14% of patients, type Ib endoleak after previous endograft deployment in 3% of patients, and penetrating aortic ulcer in 1 patient. Reintervention rate was 9% (95% CI, 4%–20%) and spinal cord ischemia was 7% (95% CI, 4%–-12%). Type II endoleak was the predominant type of endoleak in 10% of patients (95% CI, 4%–22%), followed by type I endoleak in 5% of patients (95% CI, 2%–12%) and type III endoleak in 1% (95% CI, 0%–16%) of patients. Mesenteric ischemia occurred in 6% of patients (95% CI, 3%–10%). Thirty-day mortality was 5% (95% CI, 2%–13%) and the pooled estimate for overall mortality was 21% (95% CI, 14%–31%). Conclusions: Celiac artery coverage during TEVAR is a challenging but feasible option for the treatment of TAAA diseases, providing acceptable morbidity and mortality rates. Demonstration of adequate visceral collateral pathways before definitive CA coverage is the sine quo non for the success of the technique.

Dissecting Aneurysms

Intracranial dissecting aneurysms have been frequently reported to present with fairly challenging and time-variable imaging findings that can be mostly explained by the pathological mechanisms that underline the dissection. We present two cases of spontaneous dissecting aneurysm of the supraclinoid ICA, both clinically presenting with SAH, but characterized by different progression of clinical symptoms and imaging. However, in both cases an outpouch and a mild fusiform dilation of the supraclinoid ICA was present in the initial CTA performed after the occurrence of symptoms. These findings were well depicted by the MPR reformats performed retrospectively. We postulate that this finding may represent the point of initial transmural dissection and we recommend that careful analysis of the CTA MRP reformatted images should be performed in order to detect this finding promptly.
