The management of lower extremity multilevel arterial injuries: a 10-year experience

Limb-Salvage Outcomes of Arterial Repair Beyond Time Limit at Different Lower-Extremity Injury Sites

Background

The purpose of this study was to analyze the outcomes of revascularization exceeding 12 h after arterial injury at different sites of the lower extremity.

Materal/Methods

From January 2009 to April 2017, 58 patients with 58 lower-limb arterial injuries who underwent revascularization over 12 h after trauma were included in our study. Outcomes measured, including mortality, amputation, complications, and other parameters (gait, length discrepancy, the range of movement of the knee and ankle joint, and muscle wasting) were analyzed.

Results

External iliac artery injury (EIAI) or femoral artery injury (FAI) was affected in 4 patients, superficial femoral artery injury (SFAI) in 18, and popliteal artery injury (PAI) (including proximal gastrocnemius muscle vascular (PGMV) and proximal gastrocnemius muscle vascular [PGMV]) in 36. The median time of arterial injury was 72 h (interquartile range, 59.5). No mortality was found. Amputations were performed in 16 patients due to non-viable limbs, progressing infection, or muscle necrosis. All patients were followed up (median, 52 months; interquartile range, 5.5). Of the 42 limb-salvage patients, most had a limp, muscle wasting, or ankle and knee dysfunctions, and 26 patients with knee or ankle dysfunction underwent secondary surgery.

Conclusions

Although limited recanalization of blood vessels may lead to limb complications or amputations over time, the high success rate of limb salvage still merits the surgeon’s best efforts.

The management and surgical intervention timing of enchondromas: A 10-year experience

Enchondroma, reportedly the most common primary tumor of the long bones of the hand, usually develops during the first till fourth decades of life. However, there has no consensus been reached regarding the surgical intervention timing for these patients. We aim to evaluate the optimal surgical intervention timing for the patients with fractures due to enchondromas, investigate the impact of pathological fractures on the treatment and outcomes in these patients.Medical records and X-rays of patients treated for enchondroma of the hand from 2005 to 2015 were retrospectively reviewed. We collected 148 cases in total and 92 of them had complete information including X-rays, medical records, and files of follow up.There were no significant differences in terms of consolidation time after surgery, recurrence rate, and DASH scores between the groups with and without fractures; the treatment costs were higher in the group with fractures than those without fractures; however, patients without fractures were able to resume work earlier than those with fractures.The pathological fractures associated with enchondromas have no significant impact on the treatment outcomes compared to those with simple nonfractured enchondromas. Although the cost was more expensive for patients treated primarily with pathological fractures due to enchondromas, these patients could resume their work normally much earlier than those treated by delayed surgery. Early surgical intervention is recommended for better results and no increased risks for patients with pathological fractures caused by enchondromas.
