Pancreaticoduodenectomy for pediatric and adolescent pancreatic malignancy: A single-center retrospective analysis.

Purpose: While pancreaticoduodenectomy (PD) has been extensively studied in adults, there are few data pertaining specifically to pediatric patients. We retrospectively analyzed PD-associated morbidity and mortality in pediatric patients.

Methods: Our analytic cohort included all consecutive patients ≤18years of age treated at our institution from 1993 to 2015 who underwent PD.

Three-dimensional printing of anatomically accurate, patient specific intracranial aneurysm models.

Objective: To develop and validate a method for creating realistic, patient specific replicas of cerebral aneurysms by means of fused deposition modeling.

Methods: The luminal boundaries of 10 cerebral aneurysms, together with adjacent proximal and distal sections of the parent artery, were segmented based on DSA images, and corresponding virtual three-dimensional (3D) surface reconstructions were created. From these, polylactic acid and MakerBot Flexible Filament replicas of each aneurysm were created by means of fused deposition modeling.

Persistent bilateral sciatic artery: Report of a rare case.

The sciatic artery - a rare finding on autopsy - and continuation of the inferior gluteal artery has been reported previously. On a routine dissection, bilateral persistent sciatic arteries were found in both thighs of a female cadaver. This provided evidence that the sciatic artery follows the sciatic nerve, supplies the back of the thigh and finally joins the popliteal artery near the knee.
