혈관폐색 Vascular Occlusion

[BACKGROUND] Vascular occlusion induced by hyaluronic acid injections is rare, but can lead to severe adverse events, including necrosis, blindness, and cerebral infarction. [OBJECTIVE] This study aims to explore methods of reducing the ri…

[BACKGROUND] The utilization of dermal fillers for cosmetic procedures has increased dramatically in the past several years, and so is the number of reported adverse events and complications. Most of these reports are centered on extraoral …

[BACKGROUND] Although laser Doppler imaging (LDI) accurately delineates a hypoperfused area to help target hyaluronidase treatment, laser speckle contrast imaging (LSCI) is more appropriate for assessing microvascular hemodynamics and has g…

The field of non-surgical esthetic procedures has witnessed a significant surge in demand in recent years, with neuromodulators, skin treatments, and dermal fillers contributing significantly to the industry's growth. These procedures have …

[BACKGROUND] Hyaluronic acid (HA) filler-induced vascular embolism that threatens skin integrity is an urgent situation. There is increasing evidence that percutaneous intra-arterial hyaluronidase injection is an effective therapeutic techn…

[BACKGROUND] Aesthetic treatment of the nose with hyaluronic acid (HA) fillers is increasingly popular but carries a small risk of major complications. Large patient cohorts are required to better understand this risk. [AIMS] To evaluate s…

Nonsurgical rhinoplasty using filler injections is a popular procedure; however, it carries risks of significant complications, including vascular occlusion, skin necrosis, blindness, and cerebral ischemia. We present a case of septal necro…

[BACKGROUND] Hyaluronidase (Hyal) can reverse complications of hyaluronic acid (HA) fillers, which has contributed substantially to the popularity of such procedures. Still, there are differing opinions regarding Hyal treatment, including d…

Although many free tissue transfers have been performed, free flap loss can still occur because of vascular compromise. To facilitate microsurgery, we invented the axial-view microscope (aMS), a new type of microscope that can axially visua…

[OBJECTIVE] In light of the recent US Food and Drug Administration (FDA) Class 2 safety recall notice for anastomotic coupling devices, it is important to understand related adverse events. The aim of this study was to characterize adverse …

[BACKGROUND] Achieving effective upper-face rejuvenation through forehead augmentation is essential; however, complications such as vascular occlusion leading to skin necrosis or vision loss can occur. The complex forehead anatomy, characte…

[INTRODUCTION] Arterial vascular occlusion is a rare complication of dermal filler injection. This case report describes the successful use of hyperbaric oxygen therapy in a patient with vascular occlusion after a permanent dermal filler wa…

Botulinum neurotoxin type A (BoNTA) and filler injection procedures usually provide predicted outcomes with a low incidence of complications. Most of the complications after these procedures have been extensively discussed. In this study, w…

Hyaluronic acid (HA) fillers are a relatively safe and effective means of cosmetic treatment for the face; however, as the numbers of both patients and injectors continue to rise, reports of adverse events (AEs) and ischemia are increasing.…

The incidence of breast cancer and, therefore, the need for breast reconstruction are expected to increase. The many reconstructive options available and the changing aspects of the field make this a complex area of plastic surgery, requiri…

[BACKGROUND] Surgical site infection (SSI) is a common complication following head and neck surgery. Dead space at the excision site can increase the risk of infection, abscess formation, and mortality. Herein, we evaluated the performance …

[BACKGROUND]  Pedicle occlusion with total free flap loss after microvascular lower extremity reconstruction is a considerably rare yet devastating complication. Fortunately, in the majority of cases, emergency salvage takebacks of compromi…

Liquid rhinoplasty, otherwise known as nonsurgical or filler rhinoplasty, has earned increased attention for its ability to provide surgical rhinoplasty results at a fraction of the cost and without incising the skin. However, significant c…

Trauma or lesion resection often causes complex wounds with deep soft tissue defects in extremities. Simply covering with a skin flap will leave a deep dead space resulting in infection, non-healing wounds, and poor long-term outcomes. Thus…

[OBJECTIVES] Postoperative flap monitoring is essential in oral microvascular reconstruction for timely detection of vascular compromise. This study investigated the use of attached surface probes for the oxygen-2-see (O2C) analysis system …
