Chronic lymphedema reversal following arteriovenous fistula takedown: A case report

INTRODUCTION AND IMPORTANCE

Lymphedema is a very rare complication of Arteriovenous Fistula. The commonly encountered complications following the arteriovenous fistula are thrombosis, stenosis, congestive heart failure, ischemic neuropathy, steal syndrome, aneurysm and infection. Hence, presence of Lymphedema is a rarity that must be managed vigilantly. The incidence of lymphedema following AV fistula is very rare. Presently there is lack of studies evaluating the outcome of fistula take down. The standard care for lymphedema is complex decongestive physiotherapy in most of other causes bur Fistula Take down also helps in reducing the swelling in our case.

CASE PRESENTATION

Our case is of 53 years female presented to the surgical OPD with left upper limb swelling 5 months back which was non-pitting in nature. She was a known case of Acute kidney injury with no history of other comorbidities. The swelling started about 1 year ago involving the upper parts of the left arm which was intermittent and relieved spontaneously. She has a history of brachiocephalic fistula insertion for hemodialysis access 4 years ago with diagnosis of Acute Kidney Injury. However, the fistula was never used because of patient recovering from medical management. Investigations performed were doppler and other routine tests.

CLINICAL DISCUSSION

The fistula was patent on examination confirmed by venous hum on auscultation. Fistula takedown surgery was planned after ruling out thrombosis and stenosis using doppler. Other alternatives were not considered because of lack of use of fistula. The swelling started to improve postoperatively and the patient was discharged.

CONCLUSION

Our Case report highlights the fact that the rare complication like lymphedema could occur after the arteriovenous fistula which could be managed by fistula take down surgery if the fistula is no longer in use. Though very rare lymphedema should be kept in differential for complication which can be diagnosed by examination and ruling out other causes.

Symptom Frequency, Intensity, and Distress in Patients with Lower Limb Lymphedema

BACKGROUND

Patients with lower limb lymphedema experience symptoms of pain, swelling, tightness, and heaviness in their legs. Less is known of the intensity and distress associated with these symptoms. This study sought to identify and compare the symptoms and the level of intensity and distress associated with symptoms by type of lymphatic disruption.

METHODS AND RESULTS

A cross-sectional design was used. Patients completed an online survey that included: a demographic form, the Lymphedema Symptom Intensity and Distress Survey-Leg, and an open-ended question. The most prevalent symptoms were swelling, concerns about looks, heaviness, tightness, fatigue, and reduced physical activity. Statistically significant differences were found among groups in coldness in legs (χ(2) (df=3) = 9.0, p = 0.03), lack of confidence in self (χ(2) (df=3) = 10.6, p = 0.014), and feeling less sexually attractive (χ(2) (df=6) = 12.6, p = 0.049). Group differences were also observed in the intensity of heaviness (χ(2) (df=3) = 9.11, p = 0.03), numbness, (χ(2) (df=3) = 10.66, p = 0.014), achiness (χ(2) (df=3) = 12.40, p = 0.006), skin flakiness (χ(2) (df=3) = 13.22, p = 0.004), and lack of interest in sex (χ(2) (df=3) = 8.95, p = 0.030). Statistically significant group differences were not found in distress related to symptoms.

CONCLUSIONS

Despite the number of symptoms reported by patients with lower-limb lymphedema, only a few statistically significant differences in symptoms and level of intensity were observed by type of lymphatic disruption. No statistically significant group differences were found in the distress level associated with any of the symptoms.
