Saphenous vein

A 54-year-old woman with a mycotic superior mesenteric artery (SMA) aneurysm underwent emergent aneurysm resection with a great saphenous vein bypass. Follow-up computed tomography revealed a rapidly growing recurrent SMA aneurysm at the stump. Under the diagnosis of recurrent pseudoaneurysm of SMA with a fragile stump, we performed an open dual arterial bypass using indocyanine green fluorescence angiography and endovascular coil embolization. Subsequently, the patient's recurrent mycotic SMA aneurysm was successfully managed without mesenteric ischemic complications...

INTRODUCTION AND IMPORTANCE: Multiple Hereditary Exostoses is a rare autosomal dominant bone disorder that predominantly affects males at an incidence of (1:50,000 to 1:100,000) in Western populations. The etiology is owed to mutations in the EXT gene group, specifically EXT1 and EXT2 which cause the formation of Osteochondromas. Diagnosis is typically established in childhood. Nevertheless, vascular complications are extremely rare while being potentially fatal. Therefore, timely diagnosis and treatment are vital for such patients...

Factor X (FX)-deficiency is a rare bleeding disorder manifesting a bleeding tendency caused by low FX activity levels. We aimed to explore the use of fitusiran (an investigational siRNA that silences antithrombin expression) to increase thrombin generation and the in vivo hemostatic potential under conditions of FX-deficiency. We therefore developed a novel model of inducible FX-deficiency, generating mice expressing <1% FX activity and antigen (f10low-mice). Compared to control f10WT-mice, f10low-mice had 6- and 4-fold prolonged clotting times in Prothrombin Time- and activated Partial Prothrombin Time-assays, respectively (p<0...

OBJECTIVE: To explore the clinical efficacy and advantages of laparoscopic inguinal lymphadenectomy (IL) with preservation of the great saphenous vein through subcutaneous approach via umbilical cord for the treatment of penile carcinoma patients. METHODS: The data of 27 patients with penile cancer underwent the laparoscopic inguinal lymph adenectomy with preservation of the great saphenous vein through subcutaneous via umbilical cord approach in the General Hospital of Eastern Theater Command from 2014 May to 2022 May were analyzed retrospectively...

BACKGROUND: Varicose veins affect approximately 25% of people in industrialized countries. METHODS: The study aimed at detecting apoptotic cells and histopathological changes in varicose vein walls. Patients (N.=41) with varicose veins and 30 control group patients were divided into two groups according to their age (younger and older than 50 years). Apoptosis was determined by the TUNEL assay, elastin and collagen IV expression by immunohistochemistry and ultrastructural changes by transmission electron microscopy...

OBJECTIVE: This study determined hazard factors and long-term survival rate of total arterial coronary artery bypass graft surgery over 20 years in an extensively large, population-based cohort. METHODS: A total of 2979 patients who underwent isolated CABG from April 1999 to March 2020 were studied in 4 groups- Group-A (bilateral internal mammary artery ± radial artery), Group-B (single internal mammary artery + radial artery ± saphenous vein), Group-C (single internal mammary artery ± saphenous vein; no radial artery), and Group-D (radial artery ± saphenous vein; no internal mammary artery)...

BACKGROUND AND OBJECTIVES: More than 20% of patients with extrahepatic portal vein obstruction (EHPVO) may be deemed as nonshuntable due to lack of a suitable vein. The role of "makeshift shunts" or "lesser shunts" assumes importance in such cases. In this report, the authors have shared their experience with the makeshift shunts in the management of portal hypertension in children with emphasis upon anatomic considerations, resolution of symptoms, outcomes after surgery, and shunt patency...

(1) Background Cerebral revascularization is necessary to treat intracranial arterial stenosis caused by moyamoya disease, atherosclerosis, or large complex aneurysms. Although various donor vascular harvesting methods have been reported safe, there are no reports on the histological evaluation of donor vessels for each disease, despite the variety of diseases wherein vascular anastomosis is required. (2) Methods Pathological findings of the superficial temporal artery (STA), radial artery (RA), occipital artery (OA), and saphenous vein (SV) harvested at the institution were analyzed...

PURPOSE OF REVIEW: The no-touch technique is an established method to harvest the saphenous vein (NT-SV), which is the most commonly used conduit in coronary artery bypass grafting. Herein, we summarize the foundational evidence, as well as highlight recent innovations and ongoing clinical trials involving NT-SV. RECENT FINDINGS: Through preservation of perivascular tissue for atraumatic handling and omission of manual distension, the NT-SV maintains endothelial nitrous oxide synthase levels and experiences less vascular smooth muscle cell activation, which translates to slower progression of atherosclerosis and less size mismatch of the graft and target vessel...

An epithelioid hemangioma (EH) is a rare benign vascular lesion that is usually seen in superficial small vessels within the dermis and subcutaneous tissue. Intravascular epithelioid hemangiomas of large and medium-sized vessels are rare, and only a handful of cases have been reported in the literature. Intravascular epithelioid hemangiomas are biologically benign and best treated by complete surgical excision. On occasion, lesions have been associated with aneurysmal changes in the affected vessel. Local recurrence may occur, and close clinical follow-up is advised...

The advent of excimer laser coronary atherectomy (ELCA) nearly four decades ago heralded a novel way to treat complex lesions, both coronary and peripheral, which were previously untraversable and thus untreatable. These complex lesions include heavily calcified lesions, ostial lesions, bifurcation lesions, chronic total occlusions, in-stent restenosis (including stent underexpansion), and degenerative saphenous vein grafts. We discuss the technology of ELCA, its indications, applications, and complications, and suggest the "MAXCon ELCA" technique for better outcomes without increased risk...

BACKGROUND Aortic dissection is rare after coronary artery bypass grafting (CABG). It is a potentially fatal complication of cardiac surgery. Reoperation may pose problems with thoracotomy, adhesiolysis, and myocardial protection. No standard treatment guidelines exist for chronic aortic dissection after CABG. We present a case of chronic type A aortic dissection after cardiac surgery, which was successfully treated. CASE REPORT A 65-year-old female patient presented with a medical background of hypertension, type 2 diabetes mellitus, and hyperlipidemia...

BACKGROUND: In the BEST-CLI trial (Best Endovascular Versus Best Surgical Therapy for Patients With Chronic Limb-Threatening Ischemia), a prespecified secondary objective was to assess the effects of revascularization strategy on health-related quality of life (HRQoL). METHODS: Patients with chronic limb-threatening ischemia were randomized to surgical bypass (Bypass) or endovascular intervention (Endo) in 2 parallel trials. Cohort 1 included patients with single-segment great saphenous vein; cohort 2 included those lacking suitable single-segment great saphenous vein...

Intraneural hematoma is a rare disease that results in an impaired nerve function because of bleeding around the peripheral nerve, with only 20 cases reported. Trauma, neoplasm, and bleeding disorders are known factors for intraneural hematoma. However, here we report atypical features of asymptomatic and spontaneous intraneural hematoma which are difficult to diagnose. A 60-year-old woman visited our clinic with the complaint of a palpable mass on the right calf. She reported no medical history or trauma to the right calf and laboratory findings showed normal coagulopathy...

OBJECTIVE: To explore the feasibility and recent efficacy of iliac vein molding and stenting in daytime treatment mode in patients with iliac vein stenosis. METHODS: Medical records of iliac vein molding and stenting performed in the ipsilateral great saphenous vein approach conducted from February 2017 to March 2022 were retrospective reviewed. There were 21 cases, 6 males and 15 females. Age ranged from 37 to 79 years [(62.5 ± 10.2) years]. The stenosis in the 21 limbs simply involved the common iliac veins in 16 patients, 2 patients had the simple and external iliac veins, and both the total and external iliac veins in 3 patients...

OBJECTIVE/BACKGROUND: The use of cryopreserved saphenous veins (CSVs) for the treatment of lower extremity peripheral arterial disease is an attractive option when there is no available autogenous vein. Prior studies found CSVs are at risk for aneurysmal degeneration requiring reoperation. As the management of these complications and patient outcomes is not well described, the objective of this case series is to describe the open and endovascular management of degenerative CSVs at a tertiary community center...

A 79-year-old man presented to our hospital with complaints of a sudden worsening of swelling in the right popliteal fossa and fever persisting for a week. Upon close examination, an infected popliteal artery aneurysm (PAA) was identified. Given the risk of rupture, the patient was advised to undergo surgery. The surgical procedure involved resecting the infectious PAA using a lateral approach. Additionally, a bypass was performed from the superficial femoral artery to the below-knee artery, utilizing the great saphenous vein located at the posterior aspect of the knee...

The study purpose is to review the surgical approach and evaluate the results in cases of head and neck malignancies with internal carotid artery invasion. The anatomical site of the primary tumor varied including a fixed massive metastatic neck disease of an occult intraoral carcinoma of the right tonsil, a recurrent metastatic neck tumor after laryngectomy for glottic primary carcinoma and a metastatic malignant melanoma of an unknown primary origin. In all cases carotid artery was invaded and therefore resected...

BACKGROUND: Great saphenous vein (GSV) valve incompetence is one of the most common manifestations of chronic venous insufficiency (CVI) in the lower limbs. There have been no reported attempts to repair the valve prior to the appearance of varicose morphology. METHOD: We describe two cases. Before surgery, the male patient had obvious pigmentation in the ankle area, and the female patient had obvious pain and swelling in the lower limbs after prolonged standing...

BACKGROUND: Polidocanol endovenous microfoam (PEM) has been used to treat lower extremity venous reflux for almost a decade with specific advantage in below knee (BK) truncal veins where thermal ablation poses a risk for injury to adjacent nerves. Current literature in the BK segment often examines short-term outcomes with modest sample sizes. We aim to identify factors associated with recanalization and reintervention in this subset of patients. METHODS: We performed a retrospective study of a prospectively maintained database of patients from a single institution who underwent PEM ablation for BK great saphenous vein (GSV) and small saphenous vein (SSV) reflux...
