Finger injuries to the hand with extensive soft tissue defects might be challenging to treat. Typically, the first dorsal metacarpal artery (DMA) flap is used for reconstruction, whereas closure of the donor site is routinely performed with a split-thickness skin graft. The aim of the current study is to present a surgical technique that reports a modified incision, which allows elevation of the first DMA flap for the management of the soft tissue defects of the thumb without requiring a skin graft for coverage of the donor site. A 65-year-old man presented to the emergency department with a crush injury to the thumb. The patient had an extensive skin defect on the dorsal side of the thumb extending circumferentially to the ipsilateral thenar without tendon damages, whereas sensation of the finger was found intact. Surgical intervention was performed within six hours and involved DMA flap transfer through a modified skin incision, which allowed coverage of the donor defect in the index finger with a second DMA perforator flap. 3 months postoperatively, patient’s satisfaction, sensation and range of motion (ROM) of the fingers were assessed using The Michigan Hand Outcomes Questionnaire (MHQ) and the 2-point discrimination (2-PD) test. The patient regained active ROM of the thumb and index along with complete preservation of sensation, while the final cosmetic outcome was satisfactory. The application of this technique allows coverage of both trauma defect and donor site with a single skin incision, providing a successful clinical outcome.
The pseudoaneurysm of the radial artery is an infrequent complication mainly after iatrogenic procedures, with an increased incidence over the last years. The aim of the current study was to present a rare case of a radial artery pseudoaneurysm that projected through the skin after a single arterial puncture for blood-gas analysis. A 79-year-old man, with a history of atrial fibrillation and coronary heart disease on anticoagulants, was admitted to the cardiological intermediate care unit, with pulmonary oedema due to heart failure deregulation. On the next day, his left radial artery was punctured for blood-gas analysis. No other catheterization of the vessel was executed in the following days. Six days later a pulsatile, palpable mass on the skin surface, over the site of puncture, was recognized. Subsequently a Doppler ultrasound that was performed, confirmed the diagnosis of pseudoaneurysm. The pseudoaneurysm was surgically removed under general anesthesia. The patient was hospitalized for four days for trauma monitoring and intravenous antibiotics and afterwards he was discharged from the Hospital. Three months postoperatively, no sign of recurrence was observed. The pseudoaneurysm of the radial artery is an uncommon complication that might occur even after simple iatrogenic procedures, like after a direct arterial puncture for blood-gas analysis. Therefore, specialists should always be aware of this complication in similar cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
