Short-term results of fenestrated physician-modified endografts for type1a endoleak after conventional thoracic endovascular aortic repair.

Objective: This study aims to assess the feasibility and effectiveness of physician-modified fenestrated stent grafts (PMEGs) in treating type 1a endoleak after conventional thoracic endovascular aortic repair (TEVAR) in aortic arch pathologies. Methods: Patients who developed a type 1a endoleak after conventional TEVAR were included in the study. They underwent treatment with fenestrated PMEGs, which involved single or double fenestration for the supra-aortic trunks. Results: Twenty patients were treated with PMEGs between October 2018 and November 2023. Among them, 25% received single fenestrated PMEGs and 75% received double fenestrated PMEGs. The technical success rate was 100% for both types. Eighty percent of the PMEGs had a landing zone in zone 0, whereas 20% had a landing zone in zone 2. There were no in-hospital deaths. After 30 days, 1 patient died as the result of an aortic-related cause (retrograde dissection). The mean follow-up time was 16.5 months (range, 0-60 months). No major adverse events such as stroke or spinal ischemia were reported. No type 1 or type 3 endoleaks were observed, and one type 2 endoleaks required peripheral endovascular reintervention. Conclusions: The treatment of type 1a endoleaks using fenestrated PMEGs after conventional TEVAR for aortic arch pathologies is a viable option. It is associated with acceptable rates of early and midterm major morbidity and mortality.

Combined video-assisted thoracoscopy surgery and posterior midline incision for en bloc resection of non-small-cell lung cancer invading the spine.

OBJECTIVES: This article aims to evaluate the feasibility and safety of a hybrid video-assisted thoracic surgery (VATS) approach to achieve en bloc lobectomy and spinal resection for non-small-cell lung cancer (NSCLC). METHODS: Between October 2015 and November 2020, 10 patients underwent VATS anatomical lobectomy and en bloc chest wall and spinal resection through a limited posterior midline incision as a single operation for T4 (vertebral involvement) lung cancer. Nine patients had Pancoast syndrome without vascular involvement and 1 patient had NSCLC of the right lower lobe with invasion of T9 and T10. RESULTS: There were 5 men and 5 women. The mean age was 61 years (range: 47-74 years). Induction treatment was administered to 9 patients (90%). The average operative time was 315.5 min (range: 250-375 min). The average blood loss was 665 ml (range: 100-2500 ml). Spinal resection was hemivertebrectomy in 6 patients and wedge corpectomy in 4 patients. Complete resection (R0) was achieved in all patients. The average hospitalization stay was 14 days (range: 6-50 days). There was no in-hospital mortality. The mean follow-up was 32.3 months (range: 6-66 months). Six patients (60%) are alive without recurrence. CONCLUSIONS: VATS is feasible and safe to achieve en bloc resection of NSCLC inviding the spine without compromising oncological efficacy. Further experience and longer follow-up are needed to determine if this approach provides any advantages over thoracotomy.
