Fish collagen sponge with human umbilical cord mesenchymal stem cells for diabetic wound repair in rats.

Stem cell therapy offers a novel approach to treating difbetic foot ulcers. Fish skin decellularized matrix, a type I collagen, provides a promising carrier for stem cells, creating a supportive microenvironment that enhances cell survival and therapeutic potential. This study aims to investigate the effects and mechanisms of human umbilical cord mesenchymal stem cells (HUCMSCs) loaded onto a fish collagen sponge for wound healing in diabetic rats.

repair or reconstruction of the abdominal aorta-iliac artery by autologous fascia-peritoneum with posterior rectus sheath for the treatment of the infected abdominal aortic and iliac artery aneurysms: A case series and literature review.

Background: Infected abdominal aortic and iliac artery aneurysms are considered acute and severe diseases with insidious onset, rapid development, and high mortality in vascular surgery. Currently, there is no better treatment, either anatomic or extra-anatomical repair.

Case Presentation: From February 2018 to April 2022, 7 patients with infected abdominal aortic and iliac artery aneurysms did not have sufficient autologous venous material for repair.

Experimental study of a heparin-coated venous stent fabricated by atomic layer deposition.

Objective: To evaluate the safety and efficacy of heparin-coated venous stents in animals.

Methods: We used atomic layer deposition technology to obtain a heparin coating with good stability and then prepared a heparin-coated venous stent based on this technology. The experimental stents were prepared according to the diameter of the rabbit inferior vena cava and were divided into Ni-Ti alloy stent group, Ni-Ti-AlO stent group and Ni-Ti-AlO-Heparin stent group.

Association Between Metformin and Abdominal Aortic Aneurysm: A Meta-Analysis.

Objective: To systematically examine the association between metformin and abdominal aortic aneurysm (AAA) and provide a basis for the treatment of AAA.

Methods: Pubmed, Embase, Cochrane Library, and Ovid databases were searched by computer to identify the literature related to metformin and AAA published until February 2022. The literature was screened according to the inclusion and exclusion criteria, data were extracted, and a quality assessment was conducted.

In situ reconstruction of ruptured mycotic iliac artery aneurysm with autologous fascial-peritoneal tissue: a case report and literature review.

Background: Infectious aneurysms are rare in clinic with poor therapeutic outcomes. When artery rupture occurs, the disease tends to progress resulting in a high mortality, and there remains no ideal treatment.

Case Presentation: We report a case of rupture of infectious iliac artery pseudoaneurysm, who was assigned to receive artery reconstruction with autologous fascial-peritoneal tissue and obtained satisfied short-term outcome.

Neutrophil Gelatinase-Associated Lipocalin as an Early Predictor of Contrast-Induced Nephropathy Following Endovascular Aortic Repair for Abdominal Aortic Aneurysm.

To investigate serum neutrophil gelatinase-associated lipocalin (sNGAL) and urine neutrophil gelatinase-associated lipocalin (uNGAL) as early predictors of contrast-associated acute kidney injury(contrast-induced nephropathy)following endovascular aortic repair for abdominal aortic aneurysm. Prospective cohort study. Subjects included 202 consecutive patients with abdominal aortic aneurysm diagnosed between February 2016 and October 2018.

Retrospective evaluation of the endovascular repair of the anastomotic pseudoaneurysm of the transplanted renal artery using the snorkel technique.

Objective: To evaluate the endovascular repair of the transplanted renal artery anastomotic pseudoaneurysm using the snorkel technique.

Methods: From April 2012 to December 2017, we performed endovascular repair in six patients, who were diagnosed with transplanted renal artery anastomotic pseudoaneurysm, using the snorkel technique. The "snorkel" stent and the "parallel" stent were placed in the transplanted kidney and the external iliac artery, respectively.

Guidance of Venous Stent Implantation after Catheter-directed Thrombosis in Patients with Acute Left Lower Extremity Deep Venous Thrombosis based on Pressure Gradient Differences between the Iliac Vein and Inferior Vena Cava: A Single-center Retrospective Study.

Background: Iliac vein compression syndrome (IVCS) can lead to acute deep venous thrombosis (DVT) and post-thrombotic syndrome (PTS). Endovascular venous stenting has become a preferred treatment for IVCS. In this article, we guide stent implantation by the pressure gradient of iliac vein and inferior vena cava.

Preliminary report of a new type of braided vein stent in animals.

Background: Iliofemoral vein stenosis or occlusion is a common cause of severe chronic venous insufficiency. Endovascular venous stenting has become a preferred treatment because it is minimally invasive and has a high safety profile. Despite the wide application of the wallstent, it is not specifically designed for veins.

Is May-Thurner Syndrome Combined with Left Iliac Arteriovenous Fistularare or Neglected?: Cases Report and Literature Review.

May-Thurner syndrome (MTS) is a condition in which the left common iliac vein is compressed by the right common iliac artery, which may cause swelling, pain or deep venous thrombosis of the left lower extremity. Postthrombotic syndrome, nonthrombotic chronic venous insufficiency, and recurrence after venous thrombosis are also possible complications. Although MTS combined with left iliac arteriovenous fistula is rarely reported, we treated 3 such cases in the past year.

Popliteal Vein Puncture Technique Based on Bony Landmark Positioning in Catheter-Directed Thrombolysis of Deep Venous Thrombosis: A Retrospective Review.

Background: Catheter-directed thrombolysis (CDT) is an effective method for the treatment of deep venous thrombosis (DVT). The most widely used puncture technique involves the popliteal vein of the affected leg. We introduce a new puncture technique based on bony landmark positioning.

Local and Remote Postconditioning Decrease Intestinal Injury in a Rabbit Ischemia/Reperfusion Model.

Intestinal ischemia/reperfusion (I/R) injury is a significant problem that is associated with high morbidity and mortality in critical settings. This injury may be ameliorated using postconditioning protocol. In our study, we created a rabbit intestinal I/R injury model to analyze the effects of local ischemia postconditioning (LIPo) and remote ischemia postconditioning (RIPo) on intestinal I/R injury.

Fax Extension of the Right Renal Vein With a Remodeled Receptor Saphenous Vein in a Living-Donor Kidney Transplant: A Case Report.

The right kidney may be chosen for donor safety as the donor kidney in a living renal transplant. However, the short length of the right renal vein may increase technical difficulties and affect the implanted graft. We report a method that uses the remodeled receptor saphenous vein to reconstruct and extend the transplanted renal vein.

Endovascular repair of a transplant renal artery anastomotic pseudoaneurysm using the snorkel technique.

Renal artery pseudoaneurysms after renal transplantation are extremely uncommon and are able to cause severe complications such as aneurysm rupture or renal allograft loss. Treatment often leads to transplant nephrectomy. We successfully treated a transplant renal artery pseudoaneurysm with covered stents, which resulted in well-preserved renal function.
