Analysis of High-Risk Factors and Mortality Prediction of Ruptured Abdominal Aortic Aneurysm.

Introduction: Ruptured abdominal aortic aneurysms (RAAAs) are among the most dangerous emergencies in vascular surgery, with a high death rate and numerous risk factors influencing perioperative death. Therefore, identifying the critical risk factors for RAAAs is crucial to increasing their survival rate. Our aim was to identify those risk factors from a wide range of parameters.

Transbrachial and transfemoral approaches combined with visceral protection for the treatment of juxtarenal aortoiliac occlusive disease: Technical issues and clinical outcomes.

Purpose: To evaluate the safety and efficacy of transbrachial and transfemoral approaches combined with visceral protection for the endovascular treatment of juxtarenal aortoiliac occlusive disease (AIOD) over an average 19-month follow-up period.

Methods: In this retrospective analysis, all patients with juxtarenal AIOD at a single institution were reviewed from June 2015 to January 2020. Patient characteristics, angiographic results, and follow-up outcomes were retrospectively recorded.

Methods: All patients with ECAA at a single institution were reviewed from February 2014 to February 2020. Eight consecutive patients (three men, mean age 64.

The impact of endovascular treatment on clinical outcomes of stable symptomatic patients with spontaneous superior mesenteric artery dissection.

Objective: To evaluate the efficacy and clinical outcomes of endovascular treatment for superior mesenteric artery dissection (SMAD) and its effect on superior mesenteric artery (SMA) remodeling compared with medical management alone after successful initial medical management.

Methods: In this retrospective analysis, all patients with spontaneous SMAD at a single institution were identified from March 2007 to August 2019. The primary outcomes were freedom from major adverse events (MAEs, a composite of dissection-related death, the recurrence of mesenteric ischemia symptoms, and a requirement for intervention).

Diagnostic value of color Doppler sonography for spontaneous isolated superior mesenteric artery dissection.

The present study aimed to evaluate the clinical significance of color Doppler sonography (CDS) in the diagnosis of spontaneous isolated superior mesenteric artery dissection (SISMAD). The ultrasonographic images of 19 patients with SISMAD confirmed by computed tomography angiography (CTA) were retrospectively analyzed and the ultrasonographic features were summarized. The paired t-test was used to statistically analyze the differences in parameters determined by CTA vs.

Diagnosis and treatment of acquired arteriovenous fistula after lower extremity deep vein thrombosis.

Background: Deep vein thrombosis (DVT) is a rare cause of arteriovenous fistula (AVF). The pathogenesis of acquired AVF after DVT remains unclear, and publications focusing on therapy and follow-up are also inadequate. In this study, the diagnosis and treatment of 24 patients with acquired AVF in the lower extremity after DVT was reported.

Technical issues and clinical outcomes of endovascular repair of isolated iliac artery aneurysms: A single-center experience.

Purpose: Isolated iliac artery aneurysms are the relatively uncommon condition. This study aims to evaluate the technical issues and clinical outcomes of endovascular repair in a cohort of isolated iliac artery aneurysms treated.

Methods: We retrospectively reviewed 22 consecutive patients with isolated iliac artery aneurysms between December 2006 and September 2016.

Multimodality imaging of benign or malignant tumors in the vena cava and its main branches.

Tumors arising from or secondarily involving the vena cava (VC) are broad-spectrum diseases, ranging from benign to malignant. The benign tumors include myxoma, leiomyomatosis and leiomyoma. The primary malignant tumors of the VC are rare, and of these rare entities, leiomyosarcoma is the most frequently encountered.

Endovascular repair of a Kommerell diverticulum anomaly.

A Kommerell diverticulum (KD) may predispose toward aortic aneurysm, dissection, or rupture, although they are primarily asymptomatic. We report a case of an aberrant left subclavian artery arising from a KD in a right-side aortic arch. The lesions were successfully treated by an endovascular approach involving Amplatzer vascular plug embolization of the aberrant left subclavian artery and endovascular repair of the KD.

[Clinical analysis of patients with lower extremity deep venous thrombosis complicated with inferior vena cava thrombus].

Objective: To explore the clinical profiles of patients with lower extremity deep venous thrombosis (DVT) complicated with inferior vena cava (IVC) thrombus and summarize their clinical diagnostic and therapeutic experiences.

Methods: The clinical characteristics, diagnosis and treatment of 20 hospitalized patients with DVT complicated with inferior vena cava thrombus were analyzed retrospectively.

Results: All of them were of proximal DVT.

Clinical effect of endovascular treatment on blood pressure and kidney function for hypertensive patients with renal artery stenosis.

The objective of this study was to evaluate the clinical effect of endovascular treatment on postoperative blood pressure (BP) control and kidney function of hypertensive patients with renal artery stenosis (RAS). Between January 2004 and December 2011, RAS was diagnosed in 120 renal arteries from 115 hypertensive patients. Preoperative and postoperative BPs and glomerular filtration rate (GFR) were monitored.

[Clinical analysis of 20 pregnant women with venous thromboembolic disease].

Objective: To evaluate the clinical features, diagnostic methods and treatment of venous thromboembolic disease (VTE) during pregnancy.

Methods: From June 2006 to June 2011, a total of 20 pregnant women were diagnosed VTE at the Department of Obstetrics and Gynaecology, Qilu Hospital of Shandong University. Clinical data of these patients were analyzed retrospectively.

Catheter-directed thrombolysis with a continuous infusion of low-dose urokinase for non-acute deep venous thrombosis of the lower extremity.

Objective: We wanted to evaluate the feasibility of catheter-directed thrombolysis with a continuous infusion of low-dose urokinase for treating non-acute (less than 14 days) deep venous thrombosis of the lower extremity.

Materials And Methods: The clinical data of 110 patients who were treated by catheter-directed thrombolysis with a continuous infusion of low-dose urokinase for lower extremity deep venous thrombosis was analysed. Adjunctive angioplasty or/and stenting was performed for the residual stenosis.

[Early and mid-term results of endovascular aneurysm repair for infrarenal abdominal aortic aneurysm].

Objective: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) has become a viable alternative to open surgical repair in the last decade. We report here our experience on the mid-term results of EVAR and analysis of the outcomes associated with endograft AAA repair.

Methods: Between Nov 2002 and Mar 2007, 26 patients with AAA were enrolled in a single institution.

Lateral subfascial endoscopic perforating vein surgery as treatment for lateral perforating vein incompetence and venous ulceration.

Background: The aim of this study was to evaluate the clinical results of lateral subfascial endoscopic perforating vein surgery (SEPS).

Methods: Our study was conducted from February 2002 to January 2007. Sixty-three patients with lateral incompetent perforating veins (IPVs) and venous ulceration were allocated to two groups.

Intramuscular delivery of antiangiogenic genes suppresses secondary metastases after removal of primary tumors.

The success of surgery to remove primary tumors can be compromised by the subsequent outgrowth of metastases. It is recognized that primary tumors secrete antiangiogenic factors that suppress the outgrowth of their daughter metastases. In accord we show here that surgical removal of primary EL-4 lymphomas led to a marked decrease in the levels of circulating angiostatin and endostatin, and promoted the growth of distant nodular tumors.
