Pseudo-aneurysm of the anterior tibial artery, a rare cause of ankle swelling following a sports injury

BACKGROUND: Ankle pain and swelling following sports injuries are common presenting complaints to the accident and emergency department. Frequently these are diagnosed as musculoskeletal injuries, even when no definitive cause is found. Vascular injuries following trauma are uncommon and are an extremely rare cause of ankle swelling and pain. These injuries may however be limb threatening and are important to diagnose early, in order that appropriate treatment can be delivered. We highlight the steps to diagnosis of these injuries, and methods of managing these injuries. It is important for clinicians to be aware of the potential for this injury in patients with seemingly innocuous trauma from sports injuries, who have significant ankle pain and swelling. CASE PRESENTATION: A young, professional sportsman presented with a swollen, painful ankle after an innocuous hyper-plantar flexion injury whilst playing football, which was initially diagnosed as a ligamentous injury after no bony injury was revealed on X-Ray. He returned 2 days later with a large ulcer at the lateral malleolus and further investigation by duplex ultrasound and transfemoral arteriogram revealed a Pseudo-Aneurysm of the Anterior Tibial Artery. This was initially managed with percutaneous injection of thrombin, and later open surgery to ligate the feeding vessel. The patient recovered fully and was able to return to recreational sport. CONCLUSION: Vascular injuries remain a rare cause of ankle pain and swelling following sports injuries, however it is important to consider these injuries when no definite musculo-skeletal cause is found. Ultrasound duplex and Transfemoral arteriogram are appropriate, sensitive modalities for investigation, and may allow novel treatment to be directed percutaneously. Early diagnosis and intervention are essential for the successful outcome in these patients

Socioeconomic profile of diabetic patients with and without foot problems

Introduction: To identify the differences in a socioeconomic profile between two cohorts of diabetic patients – one with diabetic foot problems and another without diabetic foot problems. Materials and methods: The cohort with diabetic foot problems (including cellulitis, abscess, osteomyelitis, septic arthritis, gangrene, ulcers, or Charcot joint disease) consisted of 122 diabetic patients, while the other cohort without foot problems consisted of 112 diabetic patients. Both were seen at the National University Hospital from January to April 2007. A detailed protocol was designed and the factors studied included patient profile, average monthly household income, education, compliance to diabetic medication, attendance at clinics for diabetic treatment, exercise, smoking, alcohol consumption, gender, and glycosylated haemoglobin (HbA1C) level. These were studied for significant differences using univariate and stepwise multivariate logistic regression analysis. Results: With multivariate analysis, Malay ethnicity (p<0.001), education of up to secondary school only (p=0.021), low average monthly household income of less than SGD $2,000 (p=0.030), lack of exercise (at least once a week, p=0.04), and elevated HbA1C level (>7.0%; p=0.015) were found to be significantly higher in the cohort with diabetic foot problems than the cohort without. Conclusions: There are significant differences in the socioeconomic factors between diabetic patients with diabetic foot problems and those without

Use of a Javid™ shunt in the management of axillary artery injury as a complication of fracture of the surgical neck of the humerus: a case report

<p>Abstract</p> <p>Introduction</p> <p>Axillary artery injury is a rare but severe complication of fractures of the surgical neck of the humerus.</p> <p>Case presentation</p> <p>We present a case of axillary artery pseudoaneurysm secondary to such a fracture, in a 82-year-old white woman, presenting 10 weeks after the initial injury, successfully treated with subclavian to brachial reversed vein bypass together with simultaneous open reduction and internal fixation of the fracture. We discuss the use of a Javid™ shunt during combined upper limb revascularisation and open reduction and internal fixation of the fractured humerus.</p> <p>Conclusion</p> <p>This case highlights the usefulness of a Javid™ shunt, over other forms of vascular shunts, in prompt restoration of blood flow to effect limb salvage. It can be considered as a temporary measure whilst awaiting definitive revascularisation which can be performed following fracture fixation.</p

Operative Management of Small Bowel Fistulae Associated with Open Abdomen

Gastrointestinal fistulae associated with open abdomen are serious complications following trauma or other major abdominal surgery. Management is extremely difficult and the mortality is still high in spite of modern medical advances. Patients who survive initial physiological and metabolic derangements require operative closure of the fistula, which is technically demanding and poorly described in the literature. Methods: A retrospective study of patients with small bowel fistulae associated with open abdomen was performed. Only patients who were stabilized sufficiently to undergo surgical closure of the fistula were enrolled in the study. The operative techniques comprised three important steps: exploratory laparotomy and resection of small bowel fistulae with end-to-end anastomosis; bridging the abdominal wall defect with a sheet of polyglycolic acid mesh; and covering the mesh with bilateral bipedicle anterior abdominal skin flaps. Results: Eight patients were included in the study. The number of operations before surgical closure of the fistula ranged from one to six (mean, 3.6). The time from first operation to surgery for fistula closure ranged from 2.5 to 7.5 months (mean, 4.4 months). Three patients had recurrent fistula, and one died (mortality, 12.5%). Hospital stay ranged from 101 to 311 days (mean, 187 days). Conclusion: We present a method of closure of small bowel fistulae associated with open abdomen and hope that this will provide surgeons encountering such complications with a good alternative for surgical management

Darker Skin Color Measured by Von Luschan Chromatic Scale and Increased Sunlight Exposure Time Are Independently Associated with Decreased Odds of Vitamin D Deficiency in Thai Ambulatory Patients

Background. Little is known about the association among skin color, sunlight exposure. and vitamin D status in Southeast Asian population. Objective. To investigate the association between skin color measured by von Luschan chromatic scale (VLCS) and vitamin D status in Thai medical ambulatory patients. Methods. Medical ambulatory patients were enrolled. The eligibility criteria were as follows: aged >18 years, stable medical conditions, and no conditions directly affecting vitamin D status. Serum 25-hydroxyvitamin D [25(OH)D] levels were assessed. Skin color at the outer forearm was assessed using VLCS which grades skin color from the lightest score of 1 to the darkest score of 36. Patients were systematically interviewed to estimate daily sunlight exposure time. Results. A total of 334 patients were enrolled. Data were expressed as mean ± SD. The mean serum 25(OH)D was 25.21 ± 10.06 ng/mL. There were 17 (5.1%), 217 (65.0%), and 100 (29.9%) patients who had light brown (VLCS score 18–20), medium brown (VLCS score 21–24), and dark brown (VLCS score 25–27) skin colors, respectively. The mean serum 25(OH)D level was higher in patients with dark brown skin than in patients with medium brown and light brown skin (28.31 ± 10.34 vs. 24.28 ± 9.57 and 19.43 ± 9.92 ng/mL, respectively, both p<0.05). Multivariate analysis showed that darker skin color and increased sunlight exposure time were independently associated with decreased odds of vitamin D deficiency (dark brown vs. light brown: odds ratio, 0.263, 95% CI: 0.081–0.851, p=0.026; medium brown vs. light brown: odds ratio, 0.369, 95% CI: 0.987–1.003, p=0.067; sunlight exposure time odds ratio per 1 minute/day increase 0.955, 95% CI: 0.991–1.000, p=0.037), after adjusting for possible confounders. Conclusions. We found that darker skin color at sunlight exposure area and increased sunlight exposure time were independently associated with decreased odds of vitamin D deficiency in Thai medical ambulatory patients

Pancreaticoduodenectomy with External Drainage of the Pancreatic Remnant

Leakage of the pancreaticojejunal anastomosis is a serious complication after pancreaticoduodenectomy. External drainage of the pancreatic remnant is one of several methods for reducing pancreaticojejunal anastomotic leakage or fistula. We investigated complications after pancreaticoduodenectomy with and without external drainage of the pancreatic remnant. METHODS: Patients who underwent pancreaticoduodenectomy at King Chulalongkorn Memorial Hospital, Bangkok, Thailand from November 1991 to October 2007 were enrolled. Before 2001, no external pancreatic drainage was employed during pancreaticojejunal anastomosis (non-stented group). Since 2001, external drainage of the pancreatic remnant has been routinely performed with a paediatric feeding tube (stented group). RESULTS: There were 28 patients in the non-stented group and 45 in the stented group. Stented patients had undergone significantly more previous abdominal operations, pylorus preserving pancreaticoduodenectomy, and end to end anastomosis of the pancreatic remnant and jejunal limb. Leakage of the pancreaticojejunal anastomosis or pancreatic fistula, overall complications, and re-laparotomy rate were significantly higher in the non-stented group (leakage or fistula 21.4% vs. 6.7%, overall complications 50% vs. 33.3%, and re-laparotomy 18% vs. 2.2%). The only death was in the non-stented group. CONCLUSION: External drainage of the pancreatic remnant after pancreaticoduodenectomy is an effective method for prevention of pancreaticojejunal anastomosis leakage and other related complications
