BACKGROUND: Kidney transplantation is the treatment of choice for patients with end-stage renal disease. The standard surgery uses the recipient's iliac vessels for vascular anastomosis. Thrombosis and/or stenosis of the iliac vein, which are possible complications of multiple vascular access points for dialysis, can be detected intraoperatively, constituting a surgical challenge. An infrequently reported option is the use of the gonadal vein. OBJECTIVES: This study aims to evaluate the outcomes of venous anastomosis in the gonadal vein in patients with iliac vein thrombosis and/or stenosis submitted to kidney transplantation...

Hemodynamics of the CL and each main uterine artery during expansion of the allantochorion from the ipsilateral side (CL side) to the contralateral side were studied in heifers (n = 8 nonbred, 9 pregnant). Progesterone concentration, vascular perfusion index for each uterine artery (by spectral ultrasonography), extent of blood flow in the CL (percentage of CL tissue with color-Doppler signals of blood flow), and intrauterine location of the expanding allantochorion (by gray-scale ultrasonic imaging) were determined daily from Days 14-60 (Day 0 = ovulation)...

BACKGROUND: Patients with tumors invading major veins may require combined resection and reconstruction. However, venous reconstruction often demands complex hepatobiliary and vascular surgical procedures. In this study, we report a simple patch repair technique for venous reconstruction using the repermeabilized umbilical vein of the round ligament. METHODS: We reviewed the outcomes of eleven patients who underwent venous wedge resection and patch repair using the repermeabilized umbilical vein of the round ligament at our institution...

Segmental internal carotid artery (ICA) and basilar artery (BA) agenesis/aplasia are rare vascular anomalies. We report an extremely rare case of combined ICA, BA, and A1 segmental absence presenting with double inter-ICA collateral communication through the intercavernous anastomosis and posterior communicating arteries. The patient presented with diplopia and transient ischemic attack. The pathogenesis of the anatomic anomalies and clinical symptoms are discussed.

BACKGROUND AND OBJECTIVE: The clinical application of laser-assisted vascular anastomosis is afflicted by unreliable and low bonding strengths as well as tedious handling during microvascular surgery. The challenge to be met arises from the flow-off of the chromophore during soldering that changes the absorption and stains the surrounding tissue, leading to an uncontrollable thermal damage zone. In this study, we investigated the feasibility to produce an indocyanine green (ICG)-loaded patch by electrospinning and tested its applicability to both in vitro and in vivo microvascular laser soldering...

INTRODUCTION: The small diameter of temporary vascular shunts for vascular trauma management may restrict flow and result in ischemia or early thrombosis. We have previously reported a clinical experience with direct, open surgical reconstruction using expanded polytetrafluoroethylene (ePTFE) stent grafts to create a "sutureless" anastomosis as an alternative to standard temporary vascular shunts. We sought to characterize patency and flow characteristics of these grafts compared to standard shunts in a survival model of porcine vascular injury...

Lateral injury of the bile duct can occur after cholecystectomy, bile duct dissection, or exploration. If direct repair is not possible, conversion to bilioenteric anastomosis can be needed with the risk of long-term bile duct infections and associated complications. We developed a new surgical technique which consist of reconstructing the bile duct with the round ligament. The vascularized round ligament is completely mobilized until its origin and used for lateral reconstruction of the bile duct to cover the defect...

Secondary lymphedema of the upper and lower extremities related to prior oncologic therapies, including cancer surgeries, radiation therapy, and chemotherapy, is a major cause of long-term morbidity in cancer patients. For the upper extremities, it is most commonly associated with prior oncologic therapies for breast cancer, while for the lower extremities, it is most commonly associated with oncologic therapies for gynecologic cancers, urologic cancers, melanoma, and lymphoma. Both non-surgical and surgical management strategies have been developed and utilized, with the primary goal of all management strategies being volume reduction of the affected extremity, improvement in patient symptomology, and the reduction/elimination of resultant extremity-related morbidities, including recurrent infections...

Situs inversus totalis (SIT) is a rare congenital anomaly. Generally, laparoscopic surgery is difficult to perform in patients with SIT because of both the potential challenges associated with unexpected vascular anomalies and the lack of standardized strategy for handling such cases. This is the first report of laparoscopic total gastrectomy with lymph node dissection for advanced gastric cancer in a patient with SIT. A 79-year-old man with SIT was diagnosed with advanced gastric cancer. We performed laparoscopic total gastrectomy with modified D2 lymph node dissection (D2 without splenectomy) and esophagojejunal anastomosis using an overlap method involving retrocolic Roux-en-Y reconstruction...

Peutz-Jeghers syndrome (PJS) is an autosomal dominant hamartomatous polyposis of the gastrointestinal tract, with pigmentation around lips, the buccal mucosa, and anal area. Patients have a strong family history. Patients of PJS present with abdominal pain, blood in stools, and occasionally melena because of polyps, along with classical mucocutaneous pigmentation. Very rarely a sporadic case of Peutz-Jeghers syndrome occurs in early childhood and adolescent. The case of a 14-year boy is reported, who presented with intussussception and bleeding per rectum due to jejunal polyp and a rectal polyp...

In the clinic 60 patients were examined, in whom reconstructive operations on the main arteries were performed for obliterating atherosclerosis (OA) of the lower extremities vessels. Efficacy of impact of Plestazol (in a 200 mg/day dose) on neointima hyperpla- sia was studied. Clopidogrel (75 mg/day) was administered to patients of comparative group. Effective criteria for estimation of the migration-proliferation disorders state in endothelial dysfunction are concentration of the intercellular adhesion molecules (ICAM) and the basic factor of the fibroblasts growth (FGFb); morphological disorders in hyperplastic reactions of neointima - determination of thickness of "intima-media" complex in accordance to the ultrasound duplex scanning data...

REVIEW
Isaac Blickstein
Single fetal death in a monochorionic twin pregnancy is more frequent than in a dichorionic twin gestation. Due to inter-twin vascular anastomosis in the monochorionic common placenta, the death of one twin causes a drop in blood pressure due to a shift of blood from the survivor to the dead fetus. If the drop of blood pressure is abrupt and serious, the survivor will die soon after (as occurs in 15% of cases). If the drop is less serious, the survivor may sustain ischemic injury (in about 26% of the cases) and if the drop in blood pressure is subtle, the survivor will be intact...

This review aims to provide a summary of the flowmeter devices used in microvascular surgery and assesses their contribution to improving the clinical outcomes of free tissue transfer. Flowmeters are widely accepted as the standard method of intraoperative assessment of the patency of coronary vascular anastomoses, providing thresholds that predict outcome. There is limited evidence regarding the use of flow measurements in plastic surgery microvascular anastomoses; however, flowmetry appears to have some role in postoperative free flap monitoring and prevention of complications...

This protocol describes detailed practical procedures for generating 3D intact and perfusable microvascular network that connects to microfluidic channels without appreciable leakage. This advanced 3D microvascular network model incorporates different stages of vascular development including vasculogenesis, endothelial cell (EC) lining, sprouting angiogenesis, and anastomosis in sequential order. The capillary network is first induced via vasculogenesis in a middle tissue chamber and then EC linings along the microfluidic channel on either side serve as artery and vein...
