Stomal prolapse is a known late complication of urinary diversions commonly used in urology. While rare, it can lead to ischemia, necrosis, and obstruction of the stoma, requiring urgent reduction before formal revision can be undertaken. Several measures can be attempted to reduce the prolapse including manual pressure and topical osmotic agents. One method that has not been reported in the urologic literature is the use of hyaluronidase. Herein, we report the first case in the literature of hyaluronidase usage to assist in reduction of an ischemic and obstructed prolapsed incontinent ileovesicostomy after manual compression failed.

Hyaluronic acid dermal fillers are becoming popular all over the world, but due to the presence of many blood vessels in the face, there is always a small possibility of vascular complications. We present a case with the ischemic involvement of chin and neck skin after accidental submental artery involvement after hyaluronic acid filler injection for chin region. Impending skin necrosis on the chin and upper neck on the right side was diagnosed quickly by observing the skin changes in the immediate postfiller phase. Pain in the mandible and in the muscles during swallowing due to possible ischemia of muscles supplied by submental artery was another crucial diagnostic feature. All parts of the affected zone were treated with high-dose pulsed hyaluronidase protocol using 4 pulses of hyaluronidase injection in first 24 hours after filler injection. Complete resolution of cutaneous ischemic changes and painful swallowing was achieved within days after treatment. Knowledge of presenting features of postfiller vascular complications and the extent of vascular territory of the involved artery is quite helpful in quickly instituting treatment leading to the near-complete recovery with minimal sequelae.

A 51-year-old woman presented with no light perception vision of the right eye 12 hours after another provider injected calcium hydroxylapatite into the glabella and dorsum of the nose. Exam and fluorescein angiography demonstrated optic nerve edema and choroidal hypoperfusion consistent with ischemia of the posterior ciliary circulation. The central retinal circulation appeared intact. One thousand two hundred units of retrobulbar hyaluronidase were injected urgently in several boluses. Oral prednisone and aspirin also were administered. Ocular massage was also initiated. One day later, visual acuity improved to light perception that remained stable at 3 months. Retrobulbar hyaluronidase injection, ocular massage, prednisone, and aspirin were correlated to recovery of light perception vision in this case of calcium hydroxylapatite filler embolization to the choroidal circulation. The mechanism for the recovery of some vision and the role of hyaluronidase and other medications remain uncertain. Further research in treatments for ophthalmic complications of facial fillers is warranted.

Hyaluronic acid injection is 1 of the most popular procedures in facial rejuvenation and augmentation. It is widely popular in the cosmetic surgery due to several advantages, which include rapid effect, minimal injury, and a short postoperative recovery period. With continuous increase in hyaluronic acid injections, many cases of hyaluronic acid injection-induced embolism have been reported. At present, methods for early treatment of hyaluronic acid injection-induced embolism include local injection of hyaluronidase, topical application of nitroglycerin ointment, massage, hot compression, and intravenous injections of antibiotics and hormones. Although early warm massage may facilitate hyaluronic acid degradation by hyaluronidase, local application of heat will also increase metabolic rate in the tissue, thereby reducing the ischemic tolerance of the tissue. Therefore, in this study, warm massage was limited to the first 30 minutes after hyaluronidase injection and was followed by local cooling using a gauze pad soaked with antibiotic saline solution. Excellent therapeutic effects were achieved with this approach. The methods of treatment for tissue ischemia caused by hyaluronic acid injection-induced embolism and clinical cases are introduced in the article.

Dermal injection of fillers is a popular and relatively safe aesthetic procedure. Severe complications are rare, but they do occur. One of the most threatening complications after dermal filler injection is skin necrosis due to vascular occlusion. Different treatment options are available, including the use of hyperbaric oxygen (HBO2) therapy. A 46-year-old female received facial dermal filler injections with calcium hydroxylapatite at an aesthetic clinic. A few days after injection she developed a burning pain, numbness of the skin and white discoloration in the injected area. Two days after injection treatment was started with hyaluronidase and warm compresses. In addition, the patient received prednisolone, sildenafil and nifedipine. After the start of these treatments, the pain, numbness and discoloration of the skin persisted. Because of dermal ischemia and to improve healing she was referred for HBO2. Treatment consisted of 10 sessions of 100% oxygen for 90 minutes in a multiplace chamber at 2.5 atmospheres absolute pressure. During HBO2 the discoloration resolved, pain and numbness disappeared, and the tissue healed completely. After a six-month follow-up she had an excellent cosmetic outcome. Given the pathophysiologic mechanisms of vascular complications after dermal filler injection, HBO2 should be considered when treating these complications.
