Am J Ophthalmol 2021 Jun 9. Epub 2021 Jun 9.

University of Ferrara, Department of Translational Medicine, Ferrara, Italy; Ospedali Privati Forlì "Villa Igea", Department of Ophthalmology, Forlì, Italy; Istituto Internazionale per la Ricerca e Formazione in Oftalmologia (IRFO), Forlì, Italy.

Purpose: To examine the ultrastructure of the natural plane of separation in grafted corneas and evaluate the outcomes of stromal peeling.

Design: Interventional case series METHODS: In this multicenter study, stromal peeling was attempted in 96 consecutive eyes with unsatisfactory vision following penetrating keratoplasty (PK) for keratoconus(n=79), herpetic keratitis(n=11) and granular dystrophy(n=6). Stromal exchange was performed by: 1) 9mm partial-thickness trephination; 2) creation of a corneal flap across the PK wound; 3) opening of the stromal component of the PK wound until a smooth, translucent natural plane was identified; 4) severing the attachment of the PK scar; 5) stromal peeling along the identified plane; 6) suturing of donor lamella.

What do surgeons need to know about the mesopancreas.

Langenbecks Arch Surg 2021 Jun 12. Epub 2021 Jun 12.

Department of Gastrointestinal Surgery, Hepatopancreatobiliary Unit, Presidente Dutra Hospital, São Luiz, Brazil.

Background: Pancreatoduodenectomy is the only treatment with a promise of cure for patients with pancreatic head adenocarcinoma, and a negative resection margin is an important factor related to overall survival. Complete clearance of the medial margin with removal of the so-called mesopancreas may decrease the recurrence rate after pancreatic resection. Here, we present some important information about the mesopancreas, total mesopancreas excision, and technical aspects to achieve negative resection margins. Read More

A Multicenter Preliminary Study of Cangrelor following Thrombectomy Failure for Refractory Proximal Intracranial Occlusions.

AJNR Am J Neuroradiol 2021 Jun 11. Epub 2021 Jun 11.

Neurology (I.S.), Bordeaux University Hospital, Bordeaux, France.

Background And Purpose: Rescue endovascular and pharmacologic approaches are increasingly being adopted after recanalization failure of acute large-vessel occlusion strokes with mechanical thrombectomy, with encouraging results. The safety and efficacy of glycoprotein IIb/IIIa inhibitors in ischemic stroke have been investigated, though cangrelor, a recent intravenous P2Y12-receptor inhibitor with a rapid onset/offset of action and a short half-life, may be a valuable option. We compared the safety and efficacy of cangrelor with those of glycoprotein IIb/IIIa inhibitors for refractory occlusions. Read More
