Correlation between Venous Thromboembolism Risk and Venous Congestion in Microvascular Reconstruction of the Lower Extremity

Staphylococcus Scalded Skin Syndrome-Induced Thrombosis Leading to Free Flap Complications: A Case Report and Review

Staphylococcal scalded skin syndrome (SSSS) is a clinical term used for a spectrum of blistering skin conditions induced by the epidermolytic toxins of the Staphylococcus aureus bacteria. The complications of SSSS include thrombosis; however, the pathophysiology of this is still poorly understood. We present a case of free anterolateral thigh (ALT) flap failure in a patient as a result of widespread flap thrombosis associated with staphylococcal scalded skin syndrome (SSSS). This is the first reported case of free flap failure associated with SSSS. Free flap failure due to acquired prothrombotic conditions, such as infection, is a rare and potentially under-reported phenomenon. This article aims to further explore the role of both thrombophilias and provoked thrombotic events in free flap failure. A review of the literature will also be presented, and cases of free flap failure in patients with infection-induced vascular complications will be summarised.

[Microcirculation in fractures of long bones of the lower extremity]

The study objective was to investigate soft tissue microcirculation in the area of a lower limb long bone fracture. We studied fractures of the lower limb long bones from 0 to 7 days of age in 17 males and 37 females. The mean age of patients was 57.33±2.53 years. Histological examination of soft tissues from the area of the lower limb long bone fracture and at the distance from the fracture was performed. Standard hematoxylin and eosin staining was used. The thickness and diameter of arterioles, venules, and capillaries were evaluated by morphometry of the sections made. The observed pattern reflects the response of the microcirculation of the soft tissues to the mechanical impact. The relative ratio of the artery diameter to the small-caliber vein diameter was 1.01±0.13, and the artery wall thickness to the vein wall thickness was 2.03±0.28, which can be considered a natural reaction of the microcirculation blood vessels to the mechanical impact in 1-1.5 weeks after the formed fracture of the lower limb long bone.
