RESUMO

BACKGROUND: This study was conducted to evaluate the differences between pre- and postoperative access conditions in percutaneous endovascular aortic repair (PEVAR). METHODS: Between December 2021 and October 2023, PEVAR was performed on 61 patients using the Perclose ProStyle (Abbott Vascular). Enhanced computed tomography and ankle-brachial index tests were performed preoperatively and postoperatively. The inner diameter and area of the iliofemoral artery were automatically measured, and the pre- and postoperative values were compared (114 legs). The same analysis was performed on 12 legs with previous groin operations; open surgical EVAR was performed in 9 legs, an endarterectomy of the femoral artery in 1, and a femoropopliteal bypass in the other leg. RESULTS: All patients were discharged without surgical site infections, lymphatic fistulas, or retroperitoneal haematomas. There were no significant differences between the pre-and postoperative inner diameter and inner area of the external iliac artery and common femoral artery. There were no significant differences between the preoperative and postoperative ankle-brachial index tests. In 12 legs with a previous groin operation, the postoperative ankle-brachial index tests and inner diameter and area of the external iliac artery and common femoral artery were statistically equal to the preoperative values. CONCLUSIONS: This study can support the safety of percutaneous endovascular aortic repair, even in patients with redo groin operations.

RESUMO

BACKGROUND: Conventional graft replacement for a juxtarenal abdominal aortic aneurysm (JRAAA) remains challenging for high-risk patients since it often requires the reconstruction of some visceral arteries. CASE PRESENTATION: A 76-year-old woman was diagnosed with an 87 × 48 mm saccular JRAAA. Open graft replacement was contraindicated because of frailty and a past history of trans-thoracoabdominal esophagectomy. Chimney endovascular aortic repair (ChEVAR) with three chimney endografts was successfully performed without any endoleaks, and each visceral circulation was kept intact. The patient was discharged uneventfully on postoperative day 8. Significant shrinkage of the aneurysmal sac and preservation of flow through each chimney graft were observed on computed tomography 6 months postoperatively, with no significant increase in serum creatinine levels on laboratory testing. CONCLUSIONS: ChEVAR can be a useful surgical option instead of conventional operations, especially for high-risk cases.

RESUMO

BACKGROUND: The celiacomesenteric trunk (CMT) is a common duct of the celiac artery (CA) and the superior mesenteric artery originating from the aorta, which is an uncommon anatomical variant of visceral artery circulation. Because of the variety of visceral circulation in those with CMT, the visceral circulation associated with each branch should be evaluated prior to surgical treatment of visceral artery aneurysm in the CMT. CASE PRESENTATION: A 64-year-old woman was diagnosed with a CA aneurysm in the CMT. Aneurysmectomy of the aneurysm was performed successfully. On preoperative selective visceral angiography, the CA was seen to bifurcate into the common hepatic and splenic artery. The left gastric artery was directly isolated from the aorta and perfused to the common hepatic and splenic artery through collateral circulation. These findings showed that celiac artery embolization is anatomically feasible, even in cases of celiac artery aneurysm rupture. CONCLUSIONS: Selective visceral angiography can contribute to surgical strategy planning for CA aneurysm with CMT.

RESUMO

Intravenous infusion of stem cells is a minimally invasive cellular delivery method, though a few have been reported in a critical limb-threatening ischemia (CLTI) animal model or patients. In the present study, we hypothesized that intravenous infusion of bone-marrow derived mesenchymal stem cells (MSCs) improves tissue perfusion in a rat hindlimb ischemia model. Hindlimb ischemia was generated in Sprague-Dawley rats by femoral artery removal, then seven days after ischemic induction intravenous infusion of 1 × 106 MSCs (cell group) or vehicle (control group) was performed. As compared with the control, tissue perfusion was significantly increased in the cell group. Histological findings showed that capillary density was significantly increased in the cell group, with infused green fluorescent protein (GFP)-MSCs distributed in the ischemic limb. Furthermore, gene expression of vascular endothelial growth factor (VEGF) was significantly increased in ischemic hindlimb muscle tissues of rats treated with MSC infusion. In conclusion, intravenous infusion of bone-marrow derived MSCs improved tissue perfusion in ischemic hindlimbs through angiogenesis, suggesting that intravenous infusion of MSCs was a promising cell delivery method for treatment of CLTI.

RESUMO

OBJECTIVE: The aim of this study was to create prediction models for two year overall survival (OS) and amputation free survival (AFS) after revascularisation in patients with chronic limb threatening ischaemia (CLTI). METHODS: This was a retrospective analysis of prospectively collected multicentre registry data (JAPAN Critical Limb Ischaemia Database; JCLIMB). Data from 3 505 unique patients with CLTI who had undergone revascularisation from 2013 to 2017 were extracted from the JCLIMB for the analysis. The cohort was randomly divided into development (2 861 patients) and validation cohorts (644 patients). In the development cohort, multivariable risk models were constructed to predict two year OS and AFS using Cox proportional hazard regression analysis. These models were applied to the validation cohort and their performances were evaluated using Harrell's C index and calibration plots. RESULTS: Kaplan-Meier estimates of two year OS and AFS post-revascularisation in the whole cohort were 69% and 62%, respectively. Strong predictors for OS consisted of age, activity, malignant neoplasm, chronic kidney disease (CKD), congestive heart failure (CHF), geriatric nutritional risk index (GNRI), and sex. Strong predictors for AFS included age, activity, malignant neoplasm, CKD, CHF, GNRI, body temperature, white blood cells, urgent revascularisation procedure, and sex. Prediction models for two year OS and AFS showed good discrimination with Harrell's C indexes of 0.73 (95% confidence interval [CI] 0.69 - 0.77) and 0.72 (95% CI 0.68 - 0.76), respectively CONCLUSION: Prediction models for two year OS and AFS post-revascularisation in patients with CLTI were created. They can assist in determining treatment strategies and serve as risk adjustment modalities for quality benchmarking for revascularisation in patients with CLTI at each facility.

RESUMO

An arterioenteric fistula is a devastating and life-threatening condition. As patients often present in extremis from hemorrhage shock, an early diagnosis and prompt life-saving interventions have to be performed. In this report, we describe a case of a 38-year-old Japanese woman who presented with hematochezia that rapidly progressed to hemorrhagic shock secondary to an iliac artery-enteric fistula that developed during bevacizumab-containing chemotherapy for recurrent cervical cancer. The patient underwent successful endovascular treatment with a covered stent-graft as a bridge to definitive open surgery.

RESUMO

BACKGROUND: In chronic limb-threatening ischemia (CLTI), although recent studies suggested that limbs classified as a higher Wound, Ischemia, foot Infection (WIfI) stage would benefit more from bypass surgery than endovascular therapy (EVT), graft unavailability is a major limitation for bypass. However, such graft unavailability is not clearly defined. This study aimed to assess whether bypass with veins judged as small by preoperative ultrasound is acceptable to achieve wound healing. METHODS: Ninety-five limbs classified as WIfI stage 3/4 that underwent infrainguinal bypass with veins were enrolled and divided into two groups based on the preoperative inner diameter of veins. Those with a diameter <2.5 mm were classified as small caliber grafts (SMGs, n=28) and those with a diameter ≥2.5 mm as sufficient caliber grafts (SUGs, n=67), and wound-related outcomes were evaluated. Wound healing rate (WHR) was analyzed in all cohort, and wound recurrence-free rate (WRF) and wound recurrence-free amputation-free survival rate (WRAFS) were calculated for limbs that achieved wound healing. A propensity score matched analysis was also performed to minimize the background difference, and 21 matched pairs were included for the analysis. RESULTS: Although the primary patency rate was significantly worse in SMGs (1-year patency, Crude model: 82.1% in SUGs and 51.0% in SMGs, P=0.0003; matched model: 77.7% in SUGs and 41.6% in SMGs, P = 0.005), the secondary patency rate was maintained in the equivalent level (1-year patency, Crude model: 81.8% in SUGs and 83.1% in SMGs, P=0.26; matched model: 77.7% in SUGs and 78.4% in SMGs, P = 0.24). One-year WHR was equivalent between the groups in both crude and matched models (Crude model: 87.0% in SUGs and 83.8% in SMGs, P=0.13; matched model: 66.3% in SUGs and 61.4% in SMGs, P = 0.65). One-year WRF and WRAFS were also equivalent (Crude model: WRF, 95.9% in SUGs and 100% in SMGs, P = 0.71; WRAFS, 87.2% in SUGs and 88.0% in SMGs, P = 0.78. Matched model: WRF, 100% in SUGs and 100% in SMGs, P = 0.85; WRAFS, 92.9% in SUGs and 78.6% in SMGs, P = 0.38). CONCLUSIONS: Although bypass with small caliber veins showed an inferior primary patency rate, WHR and WRF were equally good if grafts are maintained patent. Bypass with small caliber vein grafts would be an important option to achieve wound healing.

RESUMO

Notch signaling-modified human mesenchymal stem cell, SB623 cell, is a promising cell therapy product for ischemic stroke. With the aim to expand indications for their use for critical limb-threatening ischemia (CLTI), we hypothesized that SB623 cells improved tissue perfusion by inducing angiogenesis or arteriogenesis in a hindlimb ischemia model rat. In Sprague-Dawley rats, hindlimb ischemia was generated by femoral artery removal, then seven days after ischemic induction 1 × 105 SB623 cells or PBS was injected into the ischemic adductor muscle. As compared with the PBS group, tissue perfusion was significantly increased in the SB623 group. While capillary density did not vary between the groups, αSMA- and vWF-positive arterioles with a diameter > 15 µm were significantly increased in the SB623 group. Whole transcriptome analysis of endothelial cells co-cultured with SB623 cells showed upregulation of the Notch signaling pathway as well as several other pathways potentially leading to arteriogenesis. Furthermore, rat muscle treated with SB623 cells showed a trend for higher ephrin-B2 and significantly higher EphB4 expression, which are known as arteriogenic markers. In the hindlimb ischemia model, SB623 cells improved tissue perfusion by inducing arteriogenesis, suggesting a promising cell source for treatment of CLTI.

RESUMO

Gene or cell therapy is currently not fully efficacious for arteriosclerosis obliterans (ASO). In this study, we determined whether YS-1402, a slow-release synthetic prostacyclin agonist, promoted neovascularization and skeletal muscle regeneration in a mouse model of critical limb ischemia (CLI). We ligated the femoral artery and its branches to obtain the CLI mouse model, administered saline (S group) or YS-1402 (YS group) to the thigh adductor 1 week after femoral artery occlusion, and evaluated tissue blood flow after surgery. After treatment, the leg muscle was obtained for histological, gene expression, and protein analyses to assess angiogenesis and skeletal muscle regeneration. Tissue blood flow improved in the YS group compared with that in the S group, and the number of CD31+/α-smooth muscle actin (αSMA)+ arterioles increased in the YS group. Prostacyclin receptor (IPR), stromal cell-derived factor-1, hepatocyte growth factor, and neural cell adhesion molecule expression levels were higher in the YS than in the S group. Skeletal muscle regeneration was detected based on PAX7- and Ki-67-positive satellite cells in the YS group. Myogenin and MyoD expression was higher in the YS than in the S group. Therefore, YS-1402 promoted functional angiogenesis and skeletal muscle regeneration in the CLI mouse model, suggesting a new therapy for ASO.

RESUMO

BACKGROUND: In the current diabetes era, severe calcified femoral bifurcation lesions extending to the external elastic lamina are sometimes experienced and are technically challenging during conventional endarterectomy. We previously reported an alternative method, a decalcification technique with a Cavitron Ultrasonic Surgical Aspirator (CUSA), for calcified lesions. This study aimed to clarify the efficacy of CUSA decalcification technique. METHODS: A total of 26 limbs treated with CUSA decalcification from 2014 to 2017 were enrolled and evaluated hemodynamically with ankle-brachial index (ABI) and morphologically with computed tomography angiography (CTA). ABI was measured every 6 months, and CTA was performed early after surgery and then annually thereafter. Curved planar reformation images and cross-sectional multiplanar reconstruction images obtained by CTA were used to measure the cross-sectional area of the common femoral artery (CFA). Then, the time courses of the ABI and CFA areas were analyzed. RESULTS: The operative indication was claudication in 80.8%, rest pain in 7.7%, and tissue loss in 11.5% of the cases. A concomitant profundaplasty was performed in 34.6% of the cases. One case of an intraoperative arterial wall perforation was experienced as a procedure-related complication. Hemodynamic success rate was 96.2% (preoperative ABI: 0.37 ± 0.28, postoperative ABI: 0.75 ± 0.15, P < 0.0001) and technical success rate was 100.0% (preoperative CFA area: 4.1 ± 5.9 mm2, postoperative CFA area: 46.1 ± 17.0 mm2, P < 0.0001), with clinical improvement achieved in 95.8% of cases. Primary and secondary patency rates of the CFA were 100.0% at 2 years postoperatively, and the reintervention-free rate for the ipsilateral limb was 88.5% at 2 years postoperatively. Over a median follow-up period of 28.0 months (range, 12.3-67.0 months), the restenosis rate of CFA was 7.6%, when restenosis was defined as a >50% decrease in cross-sectional area. CONCLUSIONS: CUSA decalcification is a safe and effective alternative method to treat heavily calcified femoral lesions with a good patency rate and a low restenosis rate.

RESUMO

AIMS/INTRODUCTION: We investigated whether dulaglutide (DU)-combined conventional insulin therapy is beneficial for glycemic control in non-critically ill hospitalized patients with type 2 diabetes. MATERIALS AND METHODS: This study was a prospective, randomized controlled pilot study. Participants were randomized to either basal-plus (BP) therapy, where basal insulin and corrective doses of regular insulin were administered before meals, or BP + DU therapy, where BP therapy was combined with DU. Blood glucose (BG) levels before and after every meal were measured for 7 days after assignment to groups. Because we consider the ideal BG during hospitalization to be within 100-180 mg/dL, we defined this range as the hospitalized ideal glucose range (hIGR). We compared the percentage of BG measurements within the hIGR among all BG measurements (%hIGR), mean BG, glucose variability and insulin dose between the two groups. RESULTS: Of 54 patients, 27 were assigned to the BP group and 27 to the BP + DU group. The %hIGR was significantly higher (44% vs 56%, P < 0.001), and the frequency of BG >240 mg/dL and BG <70 mg/dL was significantly lower in the BP + DU group than in the BP group (both P < 0.001). The mean BG (183 ± 29 vs 162 ± 30 mg/dL, P < 0.05), standard deviation (P < 0.01), coefficient of variation (P < 0.01) and total regular insulin dose (P < 0.05) in the BP + DU group were significantly lower than those in the BP group. No significant side-effects were observed in either group. CONCLUSIONS: BP + DU therapy reduced the frequency of hyperglycemia and hypoglycemia, and resulted in a lower glucose variability.

RESUMO

Objective: This multicenter observational study was conducted in order to investigate the incidence of cancer in patients with critical limb ischemia. Materials and Methods: We prospectively investigated the incidence of cancer in 68 patients with critical limb ischemia over a two-year period. Patients underwent an intensive examination at enrollment, which included tumor marker levels and chest and abdominal computed tomography, as well as one- and two-year follow-up examinations. We compared the observed incidence of cancer with the expected incidence calculated from national cancer rates by the standardized incidence ratio (SIR). Results: The majority (83.6%) of the patients were men, and 92.5% of the patients had a peripheral arterial disease that was classified as Fontaine stage III or IV. During enrollment, newly diagnosed cancers were detected in seven patients. Four additional cancers were detected during the follow-up period. All of the detected cancers were asymptomatic. We observed an increased risk of cancer (SIR, 4.04; 95% confidence interval, 1.31-9.42) in patients with critical limb ischemia. Conclusion: This study suggests that critical limb ischemia is associated with an increased risk of cancer. Our findings should be taken into serious consideration by future investigators considering the use of therapeutic angiogenesis.

RESUMO

Infected popliteal aneurysm is a high-risk condition that may present as an emergency requiring an urgent attention with acute rupture and sepsis. The management of acute ischemia in the presence of local and systemic sepsis is challenging, and infection control and perioperative management during surgery are important. Here we report successful case of treating a patient with an infected popliteal aneurysm. The infection seemed to arise from the soft tissue surrounding the aneurysm, following cellulitis. Our report also includes a review of the related literature and suggests that devising methods for infection control is critical in achieving acceptable outcomes in such cases.

RESUMO

The 82nd Annual Scientific Meeting of the Japanese Circulation Society was held in Osaka, Japan, on March 23-25, 2018, when the cherry blossoms were just opening everywhere around the venue. This was the 5th Annual Scientific Meeting of JCS in which a cardiovascular surgeon served as Congress Chairperson. The main theme of this meeting was "Futurability: Pioneering the Future of Circulatory Medicine". The word, futurability, is a neologism of future ability, because we now have to contemplate what constitutes the essence of cardiovascular medicine, how it should develop as medicine for future generations, and how its ability should be displayed. The meeting was favored by splendid weather and the number of participants was recorded as being higher than 18,700. There were heated and profound discussions about the "futurability" of cardiology, cardiovascular surgery, and heart team medical care as well, in every session. The meeting was successfully completed and we sincerely appreciate the great cooperation and support from all affiliates.

RESUMO

Biologics show great efficacy in treating psoriasis, a chronic inflammatory skin disease. The high cost and side-effects of biologics, dose-reduction, elongation of administration interval and suspension are possible options. However, there has been no reliable biomarker we can use when we consider these moderations in therapy. This study was conducted to test the possibility of using serum thymus and activation-regulated chemokine (TARC) level as an indicator for step down of biologic therapy. Serum TARC level was measured in 70 psoriatic patients at Asahikawa Medical University, and a correlation of TARC and severity of skin lesions was analyzed. Referring to serum TARC level, psoriatic patients can be divided into two groups. One is a population in which serum TARC level is positively correlated with severity of skin lesions, and the other is a population with low psoriatic severity and high TARC level. Serum TARC level was higher in the group that achieved PASI-clear with biologics than in the group which did not achieve PASI-clear. Among biologics, the group treated with secukinumab, an anti-interleukin (IL)-17A agent, showed significantly higher TARC level compared with the group treated with anti-tumor necrosis factor agents. In certain populations achieving PASI-clear, serum TARC level may be a potent marker reflecting better response to IL-17A inhibitors, and in this case step down of treatment for psoriasis is possible.

RESUMO

BACKGROUND: Psoriasis, a common inflammatory skin disorder characterized by scaly erythema and plaques, is induced by dysregulation of dendritic cell- and T cell-mediated immune reaction. Receptor-interacting protein kinase 1 (RIPK1) regulates inflammatory signaling in response to stimuli such as TNF-α, TRAIL, and TLRs, resulting in apoptosis, necroptosis and NF-κB activation. However, the physiological relevance in human epidermis remains elusive. OBJECTIVE: In this study, we examined whether RIPK1 is involved in the pathogenesis of psoriasis vulgaris. METHODS: Skin samples of eight patients with psoriasis vulgaris were investigated by western blotting and immunohistochemistry. The functions of RIPK1 in keratinocytes were examined by RT-PCR and ELISA in vitro. TRAIL-neutralization-experiment was employed in an imiquimod-induced murine psoriasis model. RESULTS: In lesional psoriatic epidermis, RIPK1-expression was decreased compared with that in normal epidermis. Cytokines involved in the pathomechanism of psoriasis, such as IL-1ß, IL-17A, IL-22 and TRAIL, reduced RIPK1-expression in normal human epidermal keratinocytes (HEK) in vitro. In addition, RIPK1-knockdown enhanced TRAIL-mediated expression of psoriasis-relating cytokines, such as IL-1ß, IL-6, IL-8, TNF-α, in HEK. Numerous TRAIL-positive cells were detected in the dermis of lesional psoriatic skin, and TRAIL receptors were expressed in psoriatic epidermis and HEK in conventional cultures. Moreover, TRAIL-neutralization in an imiquimod-induced murine psoriasis model remarkably improved skin phenotypes, such as ear thickness, and TNF-α expression in lesional skin. CONCLUSIONS: These results lead us to conclude that RIPK1-downregulation in keratinocytes increases their susceptibility to TRAIL stimulation, and plays a role in the pathogenesis of psoriasis vulgaris.

RESUMO

Psoriasis is a multifactorial inflammatory disorder, in which the inflammation affects not only the skin but also the other internal organs, and can induce cardiovascular and cerebrovascular involvements. However, few predictive factors of cardiovascular diseases have been clarified in patients with psoriasis. This study was performed to verify whether diagonal earlobe creases (ELC) can reflect the hidden comorbidities in Japanese psoriatic patients. Prevalence and subtypes of ELC were analyzed in patients with psoriatic and with non-psoriatic skin diseases, and the correlation with coronary artery calcification (CAC) or fatty liver (FL) detected by computed tomography. Prevalence of CAC was approximately twice higher than data of a Japanese resident-based study previously reported. Generally, prevalence of ELC in a psoriatic group and mean age of psoriatic groups accompanied by ELC were higher and younger than those of a non-psoriatic skin disease group, respectively. Statistically significant differences were detected in the mean age of total or male subjects accompanied by bilateral ELC with complete and incomplete length. Bilateralism of ELC was closely correlated with prevalence of CAC and CAC on multiple branches in psoriatic patients (P = 6.6e-6 and odds ratio [OR] = 14.1, P = 0.00884 and OR = 10.7, respectively), but not with that of FL. On the contrary, body mass index of more than 25 was closely correlated with prevalence of FL, but not that of CAC. Comorbidities of psoriatic patients are frequently unnoticed. ELC, an apparatus-related feature, can be a useful predictive factor for hidden coronary artery involvements in psoriatic patients.

RESUMO

Anhidrosis/hypohidrosis are conditions presenting various level of sweating dysfunction. Among them, acquired idiopathic generalized anhidrosis (AIGA) presents inadequate decrease or loss of sweating without apparent neurological and dermatological symptoms except cholinergic urticaria. Recently, serum level of carcinoembryonic antigen (CEA), one of the most well-known tumor markers, has been proposed as a clinical marker reflecting activity of AIGA. This study was performed to verify the specificity and independence of serum CEA level from the other serum tumor markers especially related to adenocarcinoma. The expression of various tumor markers in the serum collected from three healthy control subjects, four AIGA cases, and a cholinergic urticaria (CU) case with elevation of serum CEA level and history of hyperthermia was analyzed using a membrane-based antibody array. In all AIGA and CU cases, the intensity of CEA was significantly increased (7.60-15.9 times compared with that of control), relatively well-reflecting the serum CEA level, and the mean intensity of CEA was 11.8 times higher than the control subjects (P = 0.0011). On the other hand, the ratio of carbohydrate antigen (CA)125 and CA19-9 was 1.93 and 0.23 times compared with the mean intensity of the control subjects, respectively, and there was no statistical significance. Immunohistochemistry on 10 AIGA cases showed increased expression of CEA but not CA19-9 and CA125 in the eccrine sweat glands. In conclusion, the elevation of serum CEA level was independent from the other tumor markers in hypohidrotic condition represented by AIGA.

RESUMO

AIMS/INTRODUCTION: There is little information regarding how to use insulin degludec (D) when diabetic patients are preparing for total colonoscopy (TCS). MATERIALS AND METHODS: A total of 12 patients with type 2 diabetes treated with insulin D and scheduled to undergo TCS were enrolled in the present study. A continuous glucose monitoring device was attached to each patient for 4 days, from two evenings before TCS to the morning after the procedure. The patients fasted for 24 h, starting after 18.00 h the day before TCS. Insulin D was only discontinued the morning of the day TCS was carried out. RESULTS: No patients experienced hypoglycemia during the daytime fasting period (08.00-18.00 h the day of TCS); the hypoglycemic index, mean glucose level, and standard deviation were 0, 141.3 ± 31.5 mg/dL and 15.6 ± 6.5 mg/dL. The mean glucose level and standard deviation during the daytime fasting period were significantly lower than during the daytime control period (08.00-18.00 h the day before TCS; P = 0.003, P = 0.001, respectively). The mean fasting glucose and fasting plasma glucose levels were significantly correlated (r = 0.78, P = 0.002), as were both the mean glucose level and standard deviation during the daytime control period, and the change in the mean glucose level (fasting period minus control period; r = -0.79, P = 0.002, and r = -0.69, P = 0.01, respectively). CONCLUSIONS: Patients can safely undergo TCS when insulin D is discontinued only once on the day of the procedure.
