ABSTRACT

This study tested whether circulatory endothelial progenitor cells (EPCs) derived from peripheral arterial occlusive disease (PAOD) patients after receiving combined autologous CD34+ cell and hyperbaric oxygen (HBO) therapy (defined as rejuvenated EPCs) would salvage nude mouse limbs against critical limb ischemia (CLI). Adult-male nude mice (n = 40) were equally categorized into group 1 (sham-operated control), group 2 (CLI), group 3 (CLI-EPCs (6 × 105) derived from PAOD patient's circulatory blood prior to CD34+ cell and HBO treatment (EPCPr-T) by intramuscular injection at 3 h after CLI induction) and group 4 (CLI-EPCs (6 × 105) derived from PAOD patient's circulatory blood after CD34+ cell and HBO treatment (EPCAf-T) by the identical injection method). By 2, 7 and 14 days after the CLI procedure, the ischemic to normal blood flow (INBF) ratio was highest in group 1, lowest in group 2 and significantly lower in group 4 than in group 3 (p < 0.0001). The protein levels of endothelial functional integrity (CD31/von Willebrand factor (vWF)/endothelial nitric-oxide synthase (eNOS)) expressed a similar pattern to that of INBF. In contrast, apoptotic/mitochondrial-damaged (mitochondrial-Bax/caspase-3/PARP/cytosolic-cytochrome-C) biomarkers and fibrosis (Smad3/TGF-ß) exhibited an opposite pattern, whereas the protein expressions of anti-fibrosis (Smad1/5 and BMP-2) and mitochondrial integrity (mitochondrial-cytochrome-C) showed an identical pattern of INBF (all p < 0.0001). The protein expressions of angiogenesis biomarkers (VEGF/SDF-1α/HIF-1α) were progressively increased from groups 1 to 3 (all p < 0.0010). The number of small vessels and endothelial cell surface markers (CD31+/vWF+) in the CLI area displayed an identical pattern of INBF (all p < 0.0001). CLI automatic amputation was higher in group 2 than in other groups (all p < 0.001). In conclusion, EPCs from HBO-C34+ cell therapy significantly restored the blood flow and salvaged the CLI in nude mice.

ABSTRACT

OBJECTIVE: Although prevention of radial artery thrombosis and cardiac complications after interventions using radial access is well investigated, there is yet no clinical study that completely evaluated access-related complications. However, there is still no consensus on what exact treatment should be used in these patients. In clinical practice, analgesic, anticoagulant, and antiplatelet treatments usually improve symptoms in patients with pain; however, in some patients, complaints may persist and may not respond to these treatments. In these patients, low-risk embolectomy with a small skin incision may be beneficial. METHODS: A total of 102 patients with radial artery thrombosis after cardiac catheterization were included in the study between 2016 March and 2018 December. After the patients' initial evaluation, anticoagulation with enoxaparin or tinzaparin and antiplatelet therapy with acetylsalicylic acid and oral/local analgesic/anti-inflammatory and local anesthetic therapy were administered for 1 month. Patients whose symptoms resolved after medical treatment were followed up as outpatients. Embolectomy was performed in consenting patients who did not respond to the medical treatment. RESULTS: Of 102 patients included in the study, 33 underwent embolectomy, whereas 69 received only medical treatment. None of the patients experienced any complications, morbidity, or mortality in the peroperative period and during the medical treatment. The pretreatment symptom scores of patients who actively use their hands in daily life and profession were significantly higher than the scores of patients who are relatively less active (P = .013). Pretreatment symptom scores were negatively correlated with age (r = -0.584); symptom scores increased significantly with the decrease of patient age. No benefit from medical treatment and need for surgery was significantly greater in patients who are younger and use their hands actively in daily life and profession (P = .028). The decrease in symptom scores after treatment was significantly greater in the surgical group than in the medical group (P = .003). CONCLUSION: Radial access should be exercised with care in patients who may develop significant thrombosis-related complaints and it is necessary to decide whether radial access is essential. If patients have ongoing symptoms despite medical treatment, embolectomy can be considered as a treatment option.

ABSTRACT

INTRODUCTION: One of the most severe complications of atherosclerosis is arterial occlusive disease (AOD) and with diabetic angiopathy (DA), is a common chronic problem in clinical practice worldwide. Hyperbaric oxygen (HBO) therapy is a therapeutic modality for solving all forms of hypoxia. AIM: To compare the treatment with HBO therapy in patients with AOD and DA ischemic symptomatology with standard treatment i.e. vasodilators, antibiotics, antiplatelets and statins, and to demonstrate the benefit of the therapeutic modality itself. METHODS: We conducted a clinical prospective study and included a total of 80 patients, divided into two groups: 40 patients with the arterial occlusive disease and lower-extremity wounds, with sub-group (n=20) treated with HBO therapy on the top of the standard therapy and 40 patients with diabetic angiopathy and diabetic lower-extremity wounds, with sub-group (n=20) treated with HBO therapy on top of the standard therapy. RESULTS: The efficacy of therapy in patients treated with HBO therapy on the top of standard therapy was significantly higher than in the group of HBO non-treated patients. There was a significant improvement in 9 patients treated with HBO therapy, while in HBO non-treated patients the significant improvement effect was observed only in one patient. CONCLUSION: HBO therapy is an effective therapeutic component in the healing of diabetic lower-extremity wounds in the patients with AOD and DA. In our patients HBO therapy on the top of standard therapeutic protocol has an effect of reducing the number of lower-limb amputations in patients with AOD and DA. These results support clinical use of HBO therapy for diabetic lower-extremity wound healing.

ABSTRACT

BACKGROUND: Conservative therapies for patients affected by Peripheral Arterial Occlusive Disease (PAOD) aim first to correct the risk factors and to slow down the disease progression. Among these, exercise has positive effects on blood flow, muscle metabolism and well demonstrated systemic effects. These include reduction of chronic inflammation markers, improvement of walking mechanics and heart function. Controlled physical training increases the ability to perform the daily activities improving life expectancy of these patients. The aim of this study is to evaluate the effects and the effectiveness of physical training performed in thermal water compared to traditional treadmill walking exercise. METHODS: 98 patients affected by IIb stage PAOD, according to Leriche-Fontaine classification, were enrolled. Patients were randomized into two groups: the first arm carried out an intensive training program under medical supervision (group A); the second one carried out a rehabilitative exercise associated with crenotherapy (group B). The following parameters were detected: Ankle-Brachial pressure index (ABI), actual claudication distance (ACD), maximum walking distance (MWD), flow mediated dilatation (FMD) and the intima-media thickness (IMT). All patients underwent Doppler echocardiography and complete biochemical assay. RESULTS: In both groups, there was a statistically significant improvement of lipidaemia compared to baseline. When compared with each other, the two groups did not show statistically significant differences. There were no significant differences between the two groups regarding echocardiographic findings. Vascular reactivity study showed a statistically significant improvement of FMD after 3 months of exercise in both groups. In crenotherapy group (B) FMD values were significantly higher than the treadmill ones (A). In both groups a statistically significant improvement in ACD was observed CONCLUSIONS: Our experience shows that crenotherapy has similar effects compared to traditional physical training in the treatment of PAOD, being equally well tolerated and safe; it gives an advantage over conventional physical training in terms of ACD and MWD improvement, although not statistically significant, and it is extremely welcome to patients compared to traditional physical training.

ABSTRACT

OBJECTIVES: Hepatic artery thrombosis remains a major complication after orthoptic liver transplant. Treatment of hepatic artery thrombosis is complex and requires a multidisciplinary approach. Retransplant is the procedure of choice. In nonsurgical candidates, endovascular options are evolving. MATERIALS AND METHODS: Based on our experience at a busy transplant center, we discuss 4 representative cases to explain the potential role of endovascular treatment beyond just attempts at recanalization. From our experience, as well as a review of the literature, we propose a clinical practice algorithm for optimal treatment of hepatic artery thrombosis after orthoptic liver transplant. RESULTS: The primary traditional endovascular interventional options remain thrombectomy, balloon angioplasty, and use of stents with the aim of revascularization. However, these methods have not proven to be effective. Ultrasonography-assisted thrombolysis, which has thus far been relatively less described in the hepatic vasculature, has the potential of producing the same angiographic results but at lower doses of the thrombolytic agent, thus decreasing the potential for hemorrhagic complications. The adjunctive use of splenic artery embolization and prompt treatment of biliary complications are in our opinion useful in "buying time" to allow adequate development of collateral "neovascularization of the liver," thus preventing further ischemia. CONCLUSIONS: Although surgical retransplant still remains the standard treatment for hepatic artery thrombosis, organ shortages and high mortality still exist. Endovascular techniques are rapidly evolving, but these techniques are dependent on expertise available and, even in the best hands, have not proven to be effective at reversing hepatic artery thrombosis. The use of a multimodality endovascular approach could salvage the liver allografts, thereby preventing retransplant or facilitating transplant at a more elective setting.

ABSTRACT

Treating lymphoedema in patients with critical arterial disease can be contraindicated. This case study describes current methods of managing lymphoedema in a patient with arterial disease and leg ulcers. The patient, a 65-year-old male, had paraplegia and lower-limb lymphoedema with leg ulceration for 18 years, as well as arterial disease. The patient was referred to the lymphoedema/vascular service in 2013. Duplex ultrasound indicated superficial femoral occlusion. The arterial disease was treated with an angiogram and angioplasty, and when the blood supply was improved, the lymphoedema was treated. Emphasis was placed on self-care and reducing the need for community nurse involvement. Selfcare included compression bandaging, use of FarrowWrap, low-level light therapy, and ulcer dressings. Outcomes were measured using a telemedicine software programme. The patient's lymphoedema was reduced, leg ulcers healed, and quality of life transformed.

ABSTRACT

BACKGROUND: This overview comments on the health-care relevance of peripheral arterial occlusive disease (PAOD) in patients with intermittent claudication (IC) and critical limb ischaemia (CLI). We evaluated different treatment modalities in terms of cost-effectiveness. METHOD: For the literature review, the Medline database (PubMed) was searched under the key words "critical limb ischemia AND cost", "critical limb ischemia AND economy", "peripheral arterial disease AND cost", "peripheral arterial disease AND economy". RESULTS: In the years 2005 to 2009, the hospitalisations of patients with PAOD rose disproportionately in Germany by 20 %, to 483,961 hospital admissions. By comparison, hospital admissions altogether increased by only 8 %. The average in-patient costs were estimated to be approximately € 5000 per PAOD-patient - a rather conservative estimate. For the patient with IC the economic data position is clear, supervised exercise training is by far the most cost-effective treatment option, followed by percutaneous transluminal angioplasty (PTA) and finally the peripheral bypass. In accordance with the guidelines of the UK, the latter is therefore indicated only if PTA fails or is technically not possible. In patients with CLI, the situation is not obvious. Indeed, a short-term economic advantage can be calculated for the PTA, the long-term comparison of both methods, however, is impossible due to insufficient data. In addition, the risk factors for the patient have to be included in the calculation. This was indeed demonstrated in the short-term, but could not be analysed in the long-term follow-up. CONCLUSION: The issue of greater cost-effectiveness of open or endovascular treatment in patients with CLI is uncertain, the studies and patient populations are too heterogeneous. Further studies are urgently needed to structure the sequence of the various treatment options in guidelines and clinical pathways.

ABSTRACT

The artery of Percheron (AOP) is a rare anatomic variant of the paramedian thalamic-mesencephalic arterial supply, arising as a solitary arterial trunk from the P1 segment of the posterior cerebral artery. Its occlusion, commonly caused by cardioembolism, leads to distal bilateral paramedian thalamic ischemia, oftentimes affecting the midbrain and/or the anterior thalamus. AOP occlusion presents with a clinical triad of altered mental status, vertical gaze palsy, and memory impairment, along with other associated symptoms. Digital subtraction angiography is effective for detecting AOP, while diffusion weighted MRI is best for diagnosis of its occlusion. Our extensive literature search sought to determine the best forms of treatment for uncomplicated AOP occlusion, with the inclusion criterion of implementation of medical treatment or other forms of therapy in patient recovery from this condition. We conclude that intravenous heparin and thrombolysis with tissue plasminogen activator are effective firstline treatment options for emergent AOP occlusion followed by a prescription of long term anticoagulants, while non-emergent cases without midbrain involvement could be treated through rehabilitation and continual monitoring by medical staff. Clinical trials of higher power are needed for a more comprehensive analysis of the treatment options for AOP occlusion.

ABSTRACT

OBJECTIVE: To observe the intervention effect of Leihong Granule (LG) in in-stent restenosis (ISR) after endovascular therapy for lower extremity arterial occlusive diseases (LEAOD). METHODS: Recruited 80 LEAOD patients who successfully underwent endovascular therapy (balloon dilation and stent implantation) were randomly assigned to two groups, the control group and the LG group, 40 in each group. Patients in the control group received basic treatment, while those in the LG group additionally took LG for 3 months. Plasma levels of IL-10, IL-18, CRP, and the intima-media thickness (IMT) of lower extremity artery were observed in the two groups between and after treatment. The rate of stent patency, ABI, intermittent claudication, rest pain, and the incidence of amputation the two groups were recorded and observed in the two groups. RESULTS: In the control group, serum levels of IL-10, IL-18, CRP, and IMT were significantly higher one month after surgery than before surgery (P < 0.05). There was no significant difference in serum levels of IL-10, IL-18, CRP, or IMT between the two groups before surgery (P > 0.05). These indices were obviously lower in the LG group than in the control group after surgery (P < 0.05). Compared with the control group, the incidence rates of intermittent claudication and the rest pain at 6 months and 12 months after surgery significantly decreased (P < 0.05). The stent patency rate at 6 months and 12 months after surgery, and ABI were significantly higher than those of the control group (P < 0.05). There was no statistical difference in the amputation rate between the two groups (P > 0.05). CONCLUSION: LG might effectively improve ischemic symptoms of affected limbs possibly through lowering the ISR rate after endovascular therapy for LEAOD through preventing immunosuppressive actions.

ABSTRACT

Peripheral arterial occlusive disease (PAOD) contributes to decreased exercise tolerance, poor balance, impaired proprioception, muscle atrophy and weakness, with advanced cases resulting in critical limb ischemia (CLI) where the viability of the limb is threatened. Patients with a diagnosis of CLI have a poor life expectancy due to concomitant cardio and cerebrovascular diseases. The current treatment options to avoid major amputation by re-establishing a blood supply to the limb generally have poor outcomes. Human skeletal muscle contains both multipotent stem cells and progenitor cells and thus has a capacity for regeneration. Phase I and II studies involving transplantation of bone marrow-derived progenitor cells into CLI limbs show positive effects on wound healing and angiogenesis; the increase in quiescent satellite cell numbers observed in CLI muscle may also provide a sufficient in vivo source of resident stem cells. These indigenous cells have been shown to be capable of forming multiple mesodermal cell lineages aiding the repair and regeneration of chronically ischemic muscle. They may also serve as a repository for autologous transplantation. The behavior and responses of the stem cell population in CLI is poorly understood and this review tries to elucidate the potential of these cells and their future role in the management of CLI.

ABSTRACT

INTRODUCTION: Drug-eluting stents (DES) have been proposed for the treatment of infrapopliteal arterial disease. We performed a systematic review to provide a qualitative analysis and quantitative data synthesis of randomized controlled trials (RCTs) assessing infrapopliteal DES. MATERIALS AND METHODS: PubMed (Medline), EMBASE (Excerpta Medical Database), AMED (Allied and Complementary medicine Database), Scopus, CENTRAL (Cochrane Central Register of Controlled Trials), online content, and abstract meetings were searched in September 2012 for eligible RCTs according to the preferred reporting items for systematic reviews and meta-analyses selection process. Risk of bias was assessed using the Cochrane Collaboration's tool. Primary endpoint was primary patency defined as absence of ≥50 % vessel restenosis at 1 year. Secondary outcome measures included patient survival, limb amputations, change of Rutherford-Becker class, target lesion revascularization (TLR) events, complete wound healing, and event-free survival at 1 year. Risk ratio (RRs) were calculated using the Mantel-Haenszel fixed effects model, and number-needed-to-treat values are reported. RESULTS: Three RCTs involving 501 patients with focal infrapopliteal lesions were analyzed (YUKON-BTX, DESTINY, and ACHILLES trials). All three RCTs included relatively short and focal infrapopliteal lesions. At 1 year, there was clear superiority of infrapopliteal DES compared with control treatments in terms of significantly higher primary patency (80.0 vs. 58.5 %; pooled RR = 1.37, 95 % confidence interval [CI] = 1.18-1.58, p < 0.0001; number-needed-to-treat (NNT) value = 4.8), improvement of Rutherford-Becker class (79.0 vs. 69.6 %; pooled RR = 1.13, 95 % CI = 1.002-1.275, p = 0.045; NNT = 11.1), decreased TLR events (9.9 vs. 22.0 %; pooled RR = 0.45, 95 % CI = 0.28-0.73, p = 0.001; NNT = 8.3), improved wound healing (76.8 vs. 59.7 %; pooled RR = 1.29, 95 % CI = 1.02-1.62, p = 0.04; NNT = 5.9), and better overall event-free survival (72.2 vs. 57.3 %; pooled RR = 1.26, 95 % CI = 1.10-1.44, p = 0.0006; NNT = 6.7). CONCLUSION: DES for focal infrapopliteal lesions significantly inhibit vascular restenosis and thereby improve primary patency, decrease repeat procedures, improve wound healing, and prolong overall event-free survival.

ABSTRACT

Transcatheter aortic valve implantation (TAVI) has become an increasingly used alternative to conventional surgical valve replacement in patients with severe aortic valve stenosis (AS) and high operative risk. We here describe a case of a TAVI performed in local anesthesia causing intraprocedural thromboembolic occlusion of non-stenotic crural arteries and its immediate successful therapeutic management by means of endovascular recanalization using a thrombus aspiration device.

ABSTRACT

BACKGROUND: Patients with recent transient ischemic attack (TIA) or stroke caused by 70% to 99% stenosis of a major intracranial artery are at high risk of recurrent stroke on usual medical management, suggesting the need for alternative therapies for this disease. METHODS: The Stenting and Aggressive Medical Management for Preventing Recurrent stroke in Intracranial Stenosis trial is an ongoing, randomized, multicenter, 2-arm trial that will determine whether intracranial angioplasty and stenting adds benefit to aggressive medical management alone for preventing the primary endpoint (any stroke or death within 30 days after enrollment or after any revascularization procedure of the qualifying lesion during follow-up, or stroke in the territory of the symptomatic intracranial artery beyond 30 days) during a mean follow-up of 2 years in patients with recent TIA or stroke caused by 70% to 99% stenosis of a major intracranial artery. Aggressive medical management in both arms consists of aspirin 325 mg per day, clopidogrel 75 mg per day for 90 days after enrollment, intensive risk factor management primarily targeting systolic blood pressure <140 mm Hg (<130 mm Hg in diabetics) and low density cholesterol <70 mg/dL, and a lifestyle modification program. The sample size required to detect a 35% reduction in the rate of the primary endpoint from angioplasty and stenting based on the log-rank test with an alpha of 0.05, 80% power, and adjusting for a 2% loss to follow-up and 5% crossover from the medical to the stenting arm is 382 patients per group. RESULTS: Enrollment began in November 2008 and 451 patients have been enrolled as of March 31, 2011. CONCLUSIONS: This is the first randomized stroke prevention trial to compare angioplasty and stenting with medical therapy in patients with intracranial arterial stenosis and to incorporate intensive management of multiple risk factors and a lifestyle modification program in the study design. Hopefully, the results of the trial will lead to more effective therapy for this high-risk disease.

ABSTRACT

OBJECTIVE: To verify the clinical efficacy of Chinese drugs for benefiting-qi, activating-blood, dissolving phlegm and removing-toxin (CDs) Combined with Conventional Treatment on post-operative vascular restenosis in patients with diabetic lower extremity arterial disease (DLEAD) underwent percutaneous transluminal angioplasty (PTA). METHODS: Fifty-six DLEAD patients underwent PTA of below-knee artery were assigned to the treatment group (32 patients) treated by basic therapy combined with CDs and the control group (24 patients) treated by basic therapy only. The changes in symptoms and signs, ankle/brachial index (ABI) and transcutaneous oxygen pressure (TCPO2) of affected limb, and blood flow (BF) in operated vessels checked with color Doppler examination were monitored and analyzed with SPSS software 16. 0. RESULTS: Overall effectiveness, including symptom score, ABI, TCPO2 and BF in patients after operation were all better in both groups significantly (P < 0.05), the improvements began to reveal in 3-6 months, and be stabilized in the treatment group, but declined gradually in the control group after then. So, the effective rate in the treatment group became significantly higher than that in the control group (75.00% vs. 41.67%, P < 0.01) at the end of the 6th month, meanwhile levels of ABI (0.65 +/- 0.12), TCPO2 (68.00 +/- 4.21 mm Hg), and BF (35.00 +/- 2.11 cm/s) in the former were better than those in the control group, respectively (0.44 +/- 0.12, 41.00 +/- 2.02 mm Hg and 21.00 +/- 1.85 cm/s, P < 0.05).

ABSTRACT

After cisplatin / 5-fluorouracil chemotherapy for nasopharyngeal carcinoma, an 18-year female patient developed aortobifemoral embolism. Besides chemotherapy, additional risk factors for arterial thromboembolic events were smoking, contraceptive medication and adjuvant antiemetic treatment with dexamethasone. Thrombophilia screening was negative. Thromboembolic complications during or after cisplatin have been reported in a frequency of 17.6 % in lung cancer patients, and in 8.4 % of patients with germ cell tumors. The incidence of arterial thromboembolic events was 9.3 % and 1.7 %, respectively. The pathogenesis of cisplatin induced thromboembolism is thought to be caused by endothelial damage leading to endothelial cell dysfunction, increased von Willebrand factor plasma levels, and hypomagnesaemia.

ABSTRACT

BACKGROUND/AIM: Hyperbaric oxygenation (HBO) is a medical treatment of a patient with 100% oxygen inspiration under the pressure higher than atmospheric in a special unit designed to let the whole patient's body rest in a chamber. The aim of the study was to determine the effect of the application of HBO treatment on the patient's lower extremities with chonic inoperabile occlusive disease by measning the parameters of perfusion scintigraphy (perfusion reserve, relative perfusion). METHODS: This investigation included 22 patients (19 males and 3 famales). Following clinical assessment of lower extremities condition according to the skin appearance and its adnexa, claudication distance was performed. Clinical condition was graded by the use of 5-point nominal scale. In all of the patients 99mTc-tetraphosmine lower extremities scintigraphy was done ten days prior to the treatment start and ten days after the treatment with HBO. Lower legs were imaged from the posterior view. Prior to imaging the patients were obligatory lying approximately half an hour. RESULTS: In 18 (86%) of the patients there was an improvement manifested as better subjective condition and better skin and its adnexa appearance. Following HBO treatment there was a statistically significant change in collecting the radiopharmac at rest. This finding indicates an increased viability of muscles as well as an increased perfusion reserve. Perfusion reserve mean values increased from 39.99 to 50.86%, and from 38.46 to 49.33% for the right and the left lower leg, respectively. This parameter clearly indicates favorable effects of HBO treatment pertaining neoangiogenesis and, consequently, increased viability of the lower leg muscles. It was also obvious in visual analysis of the obtained images. CONCLUSION: The obtained results confirm that muscle perfusion measured by the parameters of perfusion scintigraphy using 9mTc-tetrophosmine (perfusion reserve, relative perfusion) in patients with inoperabile occlusive disease of the lower leg arteries significantly increases after the application of HBO treatment.

ABSTRACT

Calcific uremic arteriolopathy (CUA) is a rare, life-threatening disease, typically affecting patients with end-stage renal disease. It is characterized by widespread vascular calcification, endothelial fibrosis and end-organ ischemia. The mortality rate is high with infection and sepsis being the most common causes of death. Common therapies include restoration of calcium and phosphorous homeostasis, wound care and pain control. Although soft tissue calcification is a known complication in children with advanced renal disease, the incidence of CUA in pediatrics remains unknown. Additionally, current literature regarding its management in pediatric patients is lacking. We report the case of a 17-year-old African-American male patient with end-stage renal disease secondary to Wegener's granulomatosis who developed CUA after 3 years on peritoneal dialysis. Treatment with sodium thiosulfate (STS) and hyperbaric oxygen (HBO) therapy alone was ineffective, forcing the patient to undergo bilateral below the-knee-amputation (BKA) 5 months after presentation. It was not until peritoneal dialysis had been changed to daily hemodialysis, while continuing STS and HBO therapy, that the patient demonstrated complete resolution of CUA on repeat bone scan. Based on these findings, and the extremely high mortality rate associated with this disease, CUA management requires early and aggressive intervention with multi-faceted therapy, including prompt conversion from peritoneal dialysis to hemodialysis, STS infusions and hyperbaric oxygen therapy.

ABSTRACT

BACKGROUND: Increasing use of dermal fillers, especially with the U.S. introduction of long-term and permanent fillers, is expected to increase the number of complications seen after treatment with these materials. OBJECTIVES: To provide physicians with an overview for treatment of dermal filler complications. RESULTS: Complications of dermal filler use can be treated successfully based on a firm understanding of the mechanisms and limitations of filler action and wound healing. Complications can be classified as immediate, early, or delayed onset; available treatment options are presented. CONCLUSION: Short- and long-term dermal fillers are increasingly becoming popular treatment options for signs of facial aging. Complications, although not common, can be treated effectively and excellent outcomes achieved.
