Anterior graft migration in posterior lumbar interbody fusion: A case report and literature review

Key Clinical Message

Spine surgeons should be aware of the possibility of anterior displacement of the grafted bone during PLIF and the potential for severe complications that may arise because of such displacement so that preparations can be made for a proper response.

Abstract

We report two cases of anterior displacement of the grafted bone after posterior lumbar interbody fusion (Graphical Abstract A-D). The patients did not require additional surgery. The anterior migration of grafted bone or cage can cause damage to anterior organs and blood vessels. Therefore, a careful surgical procedure is necessary.

The Challenge of Treating Abdominal Aortic Aneurysms with Hostile Neck Anatomy: An Overview

Hostile aortic neck anatomy challenges the outcomes of endovascular abdominal aortic aneurysm repair (EVAR). Besides reverting to open surgical repair (OSR), thoughtful endograft selection and a number of advanced endovascular techniques have been suggested as potential solutions for preventing proximal seal zone complications, improving EVAR durability, and preventing aneurysm-related death. Each technique is associated with advantages and limitations and there has not been a credible direct comparison amongst them in the form of a well-designed prospective trial. The not infrequent presence of multiple hostile anatomic characteristics further complicates decision making and challenges the surgeon's skills. This paper serves as an overview of hostile neck anatomy and its implications on EVAR. We provide a concise literature review with the purpose of outlining the treatment modalities and outcomes in this patient population.

Asymptomatic synthetic vascular graft migration to duodenum after living donor liver transplantation: report of two cases

BACKGROUND

In this study, we present the results of two patients with vascular graft migration to the duodenum after liver transplantation.

METHODS

The results of two patients who underwent living donor liver transplantation and vascular graft to the duodenum were evaluated.

RESULTS

In our center, 201 liver transplants were performed, including 154 a right lobe living donor liver transplant. A synthetic graft was used to reconstruct segment 5 and 8 hepatic veins in 78 of the 154 LDLT. During the mean follow-up 19.6 ± 12.1 months (1-44 months), graft migrated to the duodenum in two patients who were present in this study. Contrary to the literature, it was followed nonoperatively. No problem was observed in the follow-up process.

CONCLUSION

In patients with vascular graft migration to the duodenum after living liver transplantation, non-operative follow-up can be performed in appropriate patients.
