Emergency evacuation low-pressure suction for the management of extravasation injuries - a case report.

BACKGROUND: Extravasation is the movement of fluid outside its conduit into the extracellular tissue, possibly leading to a local inflammatory reaction, compartment syndrome, tissue necrosis, and full thickness skin loss at the affected area. To prevent these complications, early recognition, referral and treatment of an extravasation injury is of utter importance. CASE REPORT: We present a case, illustrating an extravasation injury into the breast managed by a renovated surgical technique - emergency evacuation low-pressure suction (EELS). A 54-year-old woman attended the emergency department with 1.5 L of total parenteral nutrition leaked into her right breast via a central portal catheter. The patient was seen within 24 hours of the incident, and presented with a diffuse swollen, tender and erythematous right breast but no overlying skin necrosis. Dry EELS via two small stab incisions was performed to evacuate the extravasated total parenteral nutrition and to minimise the aspiration of healthy fat tissue of the breast. Only a few cases of extravasation injuries into the breast have been described and most cases involve chemotherapy extravasation from a central catheter. Presumably there is an underreporting of this complication in the literature. CONCLUSION: This case-report promotes the use of aspiration in the management of diffusely spread extravasated injuries. EELS is a more appropriate term than liposuction, as there is no intention to evacuate healthy fat tissue. This new term is less confusing and might help medical staff and patients to better understand the treatment as it will break the affiliation with an aesthetic procedure. It is an effective and cosmetically satisfactory technique to treat early total parenteral nutrition extravasation injury at the level of the breast.

Anatomical variations of the upper thoracic sympathetic chain: a review.

ABSTRACT OBJECTIVES: The objective of this study is to provide a thorough overview of the anatomical variations of the upper thoracic sympathetic trunk to improve clinical results of upper thoracic sympathectomy. In addition, this study strives for standardization of future studies regarding the anatomy of the upper thoracic sympathetic chain. METHODS: The Web of Science, PubMed and Google Scholar databases were searched using keywords, alone or combined, regarding the anatomy of the thoracic sympathetic chain. The search was limited to studies performed in humans. RESULTS: Fifteen studies were finally included. Cervicothoracic ganglion and nerve of Kuntz were present in 77% and 53%, respectively. The upper thoracic ganglia were predominantly located in their corresponding intercostal space with a relatively downwards shift at the lower thoracic levels. The right sympathetic trunk is prone to have more communicating rami then the left. The lower levels of ganglia tend to have more normal rami. No clear pattern was found concerning the presence of the ascending rami and there was a decrease in the number of descending rami as the chain runs caudally. The intercostal rami remain a rare anatomical variation. CONCLUSIONS: This study presents an overview of the anatomy of the upper thoracic sympathetic chain. Its results may guide upper thoracic sympathectomy to improve clinical results. This review also provides a baseline for future studies on anatomical variations of the thoracic sympathetic trunk. More uniform reporting is necessary to compare different anatomical studies.
