RESUMO

Popliteal artery entrapment syndrome (PAES) is a rare vascular disease, and cases of bilateral PAES associated with distinct symptoms in each of the affected legs are very rare. In an effort to improve current understanding regarding the presentation and treatment of this condition, a case of bilateral PAES is herein described with a corresponding review of the associated literature. The overall process of diagnosing and treating one patient affected by bilateral PAES was retrospectively assessed to provide comprehensive insight regarding this disease. This patient was diagnosed via contrast-enhanced computed tomography (CT), and right-sided symptomatic PAES was successfully treated via autogenous saphenous venous graft arterial bypass surgery. In contrast, the asymptomatic left-sided PAES in this patient was subject to close follow-up monitoring. Over a 2-year postoperative follow-up period, this patient did not experience any symptoms or complications. As such, autogenous saphenous venous graft arterial bypass surgery represents a safe and efficacious means of treating PAES, whereas surgery may not be required for cases of asymptomatic PAES even in patients with a bilateral presentation.

RESUMO

BACKGROUND: Currently there is no consensus on the optimal management of small-for-size syndrome following liver transplantation. Here we describe a technique to alleviate portal hypertension and improve the hepatocyte reperfusion in small-for-size liver transplantation in a Lewis rat model. METHODS: The rats underwent trans-portal vein intra-hepatic portosystemic shunt using a self-developed porous conical tube (TPIPSS: Fig. 1) on small-for-size liver transplants (SFS) with right lobe graft. The treatment effect was evaluated by comparing hemodynamic parameters, morphological changes, serum parameters, ET-1 and eNOS expression, hepatocyte proliferation and apoptosis, CYP3A2 levels, postoperative complications, and survival between the two groups with SFS liver transplants. RESULTS: Porous conical prosthesis prolonged the filling time of small-for-size grafts. Moreover, grafts with TPIPSS showed a lower portal vein pressure, improved microcirculatory flow, alleviated histological changes, decreased ET-1 and increased eNOS expressions, and significantly less damage to liver function comparing to grafts without TPIPSS. Mean survival and overall 30-day survival were significantly higher in the TPIPSS group. CONCLUSIONS: These results demonstrate that porous conical tube as trans-portal vein intra-hepatic portosystemic shunt device is an effective way to alleviate portal vein hypertension and improve hepatocyte reperfusion after small-for-size liver transplantation.

RESUMO

OBJECTIVES: Cystic adventitial disease is an extremely rare vascular disorder and is often misdiagnosed. In order to improve the knowledge and treatment of this disease, a case of venous cystic adventitial disease was reported. METHODS: The whole processes about the diagnosis and treatment of one patient with venous cystic adventitial disease was retrospectively studied. RESULTS: This case of venous cystic adventitial disease was diagnosed accurately by contrast-enhanced computed tomography and treated successfully by surgical resection. No complications were detected after one-year post-operative follow-up. CONCLUSIONS: Surgical resection is a safe and effective method for the treatment of venous CAD.

RESUMO

OBJECTIVES: The pathogenic mechanisms of Thromboangiitis Obliterans (TAO) are not entirely known and autoimmune inflammation plays a vital role in the initiation and continuance of TAO activity. The authors investigated in this study the role of the TLR signaling pathway in the pathogenesis of TAO. METHODS: First, the authors detected the expressions of MyD88, TRIF and NF-κB in vascular walls of 46 patients with TAO and 32 patients with trauma and osteosarcoma by western blot assay. Second, the authors detected the cellular localization of MyD88, TRIF and NF-κB in vascular walls of patients with TAO by immunofluorescent assay. RESULTS: The protein expressions of MyD88, TRIF and NF-κB were much higher in vascular walls of TAO patients (p < 0.05). Higher expressions of MyD88 and NF-κB were detected both on vascular endothelial and vascular smooth muscle cells of TAO patients. However, higher expression of TRIF was just detected on vascular smooth muscle cells of TAO patients. CONCLUSIONS: These dates suggest that the TLR signaling pathway might play an important role in the pathogenesis of TAO, it might induce vasospasm, vasculitis and thrombogenesis to lead to the pathogenesis and progression of TAO.

RESUMO

AIM: To investigate the mechanisms by which Csk-binding protein (CBP) inhibits tumor progression in esophageal carcinoma. METHODS: A CBP overexpressing esophageal carcinoma cell line (TE-1) was established. The growth, invasion, and migration of CBP-TE-1 cells, as well as the expression of Src were then determined and compared with those in normal TE-1 cells. RESULTS: The expression of Src was decreased by the overexpression of CBP in TE-1 cells. The growth, invasion, and migration of TE-1 cells were decreased by the overexpression of CBP. CONCLUSION: This study indicates that CBP may decrease the metastasis of esophageal carcinoma by inhibiting the activation of Src. CBP may be a potential tumor suppressor and targeting the CBP gene may be an alternative strategy for the development of therapies for esophageal carcinoma.
