혈관폐색 Vascular Occlusion

Vascular complications following hyaluronic acid filler injections are rare but may lead to ischemia and necrosis. Effective management often relies on the early administration of hyaluronidase to restore perfusion and prevent long-term dam…

Postoperative venous thrombosis is a known complication of free flap reconstruction, yet thrombosis of the external jugular vein (EJV) remains underreported. We present two cases of EJV thrombosis following free jejunal transfer, both detec…

Artificial intelligence (AI) and machine learning (ML) technologies are transforming reconstructive microsurgery through data-driven approaches that enhance precision and standardize clinical workflows. These innovations address long-standi…

[BACKGROUND] Columellar incision techniques for multiply operated and/or severely compromised noses are critical in reconstructive rhinoplasty, because they impact both the final outcome and the risk of complications, such as wound dehiscen…

Reconstructing large knee defects after sarcoma resection poses a significant surgical challenge, particularly when vascular anatomy variations or intraoperative vessel damage limit conventional reconstructive options. Achieving stable, ten…

[INTRODUCTION] The rise in clinical procedures utilizing dermal fillers necessitates preparedness for potential emergencies. Effective management of complications arising from filler use, including vascular occlusions and allergic reactions…

[BACKGROUND] Hyaluronic acid (HA) fillers are popular for their minimally invasive nature and immediate aesthetic outcomes, but vascular compromise remains a significant complication. This study investigates optimized therapeutic strategies…

[OBJECTIVE] Late free flap failure is an unusual setback for patients; we investigated the etiology and management of late flap failure. [STUDY DESIGN] Single-institution retrospective review of 1959 free flaps from 2010 to 2023 for head a…

[BACKGROUND] Microsurgical free flap reconstruction is a highly technical surgery, usually performed in high-volume specialized centers. During the last 20 years, we had to perform occasional microsurgical reconstructions in our plastic sur…

[BACKGROUND] Hyaluronic acid (HA) injection as a facial filler is widely used for facial contouring and is generally believed to be safe and effective. Although extremely rare, serious complications, such as infection, skin necrosis due to …

[BACKGROUND] The increasing popularity of cosmetic procedures has led to a rise in both surgical and nonsurgical interventions. Rhinoplasty, particularly nonsurgical rhinoplasty using injectable fillers such as hyaluronic acid (HA), has bec…

[OBJECTIVE] Microvascular free flap reconstruction for head and neck defects carries a 95% success rate. When flap compromise occurs, it is often due to vascular occlusion. This study seeks to determine what impact lovenox prophylaxis has o…

Hyaluronic acid (HA) fillers offer a minimally invasive alternative for breast augmentation, appealing to young female patients seeking natural results and minimal recovery time. However, achieving optimal outcomes requires a thorough under…

Treatment of suspected upper lip area vascular occlusion caused by facial hyaluronic acid filler injections with hyperbaric oxygen is reported. The patient was initially treated with hyaluronidase injections in the cosmetic clinic then agai…

[INTRODUCTION] Tranexamic acid (TXA) is commonly used in surgical settings to reduce blood loss. Due to its antifibrinolytic properties, TXA theoretically increases the risk of thrombosis. In this study, the use of TXA was assessed in patie…

[BACKGROUND] Dermal filler-induced alopecia is a rare yet significant complication of aesthetic procedures primarily associated with vascular occlusion and subsequent tissue ischemia. Hyaluronic acid (HA) fillers, though widely used for fac…

Vascular complications, following the application of non-permanent, hyaluronic acid-based tissue fillers are a rare but very serious and rapidly progressive disorder that can, in extreme cases, lead to skin necrosis, blindness, or a stroke.…

[BACKGROUND] Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the us…

Dermal filler-based aesthetic procedures have gained widespread acceptance globally and are recognized for their safety profile; however, complications such as vascular occlusion can occur, necessitating immediate intervention. While multip…
