Late Sterile Abscess Formation in Carotid Endarterectomy Following Use of BioGlue: A Word of Caution

Sterile peri-graft abscess formation following aortic replacement: A word of caution for usage of BioGlue®

We report sterile peri-graft abscess formation following an ascending aortic and hemiarch replacement for acute type A aortic dissection, possibly caused as a reaction to BioGlue^®. The patient was successfully treated by drainage, cleaning, removal of BioGlue^® remnants, three sessions of negative-pressure wound dressing, and secondary chest closure.

The Effects of Using Bioglue in Nasal Septal Surgery

OBJECTIVES

Nasal septal surgery is one of the most common surgical procedure performed by otolaryngologists. Nasal packs are used for bleeding control, prevention of septal hematoma, replacement of mucoperichondrial flaps, and stabilization of the septum after nasal septal surgery. The aim of this study was to investigate the effects of albumin-glutaraldehyde-based tissue adhesive (Bioglue), which can be used as an alternative to nasal pack on the nasal septum after experimental nasal septum surgery.

METHODS

A total of 16 female Wistar albino rats were randomly separated into the study group (n = 10) and the control group (n = 6). After raising the mucoperichondrial flap on one side of the septum, Bioglue was used to fix the mucoperichondrial flap over the septal cartilage ın the study group and nasal packs (Merocel) were used for fixation in the control group. The rats were sacrificed at 2 and 4 weeks after septoplasty. All the tissue samples were evaluated under light microscope by the same pathologist in respect of foreign-body reaction, degree of inflammation, granulation tissue, fibrosis, cartilage damage, and cilia and goblet cell damage. In the control group, the Merocel packs were removed after 2 days and the groups were compared in terms of hematoma.

RESULTS

No hematoma was observed in any group. Septal perforation was determined in all the study group participants and loss of cilia and goblet cells and foreign-body reaction were found in 8 samples of the study group participants and in none of the control group.

CONCLUSIONS

The results of this study show that Bioglue caused segmental cartilage injury; therefore, it may not suitable for use following septal surgery.

Computed tomography perfusion abnormalities after carotid endarterectomy help in the diagnosis of reversible cerebral vasoconstriction syndrome

Acute neurologic deficits in the postoperative period after carotid endarterectomy (CEA) can prompt extensive diagnostic evaluation. Reversible cerebral vasoconstriction syndrome (RCVS) is an underrecognized cause of acute neurologic deficit after CEA. We present the case of RCVS in an 84-year-old male patient who had experienced left limb weakness after CEA, prompting multiple code stroke activations. The present case is novel because the obtained computed tomography perfusion imaging studies demonstrated abnormalities that have not been previously described in patients with RCVS. These findings, combined with the cerebral angiography findings, led to the rapid diagnosis and delivery of intra-arterial vasodilator therapy. He experienced subsequent resolution of his symptoms and radiologic abnormalities.

Cutaneous-Pericardial Fistula: Rare Complication of Transapical Aortic Valve Replacement-Case Report and Literature Review

Cutaneous-pericardial fistula is a rare complication of transapical aortic valve replacement; only a few cases are reported in the literature. It is part of a wide range of surgical site infection manifestations that could emerge after surgery. Due to its proximity to the heart, the risk of infectious lesions of adjacent structures and inoculation of pathogens on the prosthetic valve can lead to life-threatening complications. We report here a case of successful surgical treatment through reduced ribs and soft tissue operative trauma.
