Vascular and Endovascular Surgery

Unlike other visceral artery aneurysms, pancreaticoduodenal artery aneurysms (PDAAs) should be treated regardless of their size. There are no reports on PDAA associated with celiac artery (CA) dissection. We, here, report the case of a patient with a ruptured PDAA with concomitant CA dissection. A 44-year-old Korean man presented to the emergency room of another hospital 29 days ago due to a sudden onset of abdominal pain. Contrast-enhanced abdominal computed tomography (CT) revealed a large right retroperitoneal hematoma and CA dissection...

PURPOSE: To evaluate the safety, feasibility and technical aspects of endovascular treatments for inferior vena cava (IVC) thrombosis secondary to deep venous thrombosis of the lower extremities. MATERIALS AND METHODS: A retrospective study of patients from two centres who received endovascular treatment for IVC thrombosis from January 2015 to December 2020. Under the protection of the IVC filter, all lesions were treated with manual aspiration thrombectomy (MAT) followed by catheter-directed thrombolysis (CDT)...

Giant hepatic pseudoaneurysms are rare after injury. We report a case of a 20-year-old male, post gunshot injury to his right upper quadrant of the abdomen with delayed blood loss. CTA of the abdomen demonstrated a 6.5 cm right hepatic artery pseudoaneurysm. This was successfully embolized with balloon assisted trans-arterial thrombin injection.

INTRODUCTION: Single branched thoracic endografts (SBTEs) have been designed for pathology requiring zone 2 seal during thoracic endovascular aortic repair (TEVAR). Numerous criteria must be met to allow for their implantation. Our aim was to analyze anatomic suitability for a next generation SBTE. METHODS: We reviewed 150 TEVAR procedures between 2015 and 2019. Proximal seal was: zone 0 in 21 (16%), zone 1 in 4 (3%), zone 2 in 52 (40%), zone 3 in 45 (35%), and zone 4 or distal in 7 (5%)...

Re-rupture 2 years after endovascular aortic aneurysm repair (EVAR) rupture is an extremely rare event and limited data exist in the literature. We present an interesting case of a patient with an abdominal aortic rupture that had undergone 2 years before an endovascular repair for rupture after EVAR due to a type IA endoleak. The patient underwent a successful embolization of the type IA endoleak. Onyx was used to seal the gutter between the aortic wall and the endograft and the 1-month post-embolization CT showed complete sealing with no contrast in the sac...

Background: Lymphangiomyomatosis is a rare disease involving the lymph vessels, causing obstruction and cystic formation with an incidence of 3-8 per million women. The disease might be sporadic or inherited. Lymphangiomyomatosis mostly affects the pulmonary system, whereas extrapulmonary Lymphangiomyomatosis may present in various site, occasionally as a localized abdominal mass. The diagnostic process might entail surgical resection to obtain a specimen for pathology that may also help to achieve a long-term control of the disease...

BACKGROUND: Little evidence is available on post-pulmonary embolism impairment (PPEI), a recently defined complication of pulmonary embolism (PE) encompassing dysfunctional clinical and imaging parameters. In the present study, we sought to evaluate its frequency with a focus on the main components. METHODS: In this prospective registry, we included patients with a confirmed diagnosis of acute PE and focused on those with initial right ventricular (RV) dysfunction...

BACKGROUND: Disseminated Intravascular Coagulation (DIC) after Endo-Vascular Aneurysm Repair (EVAR) is a highly uncommon clinical entity. With only a few case-reports available, its management strategy still remains enigmatic. OBJECTIVES: The purpose of this study was to retrieve, synthesize, and appraise all existing data for DIC after EVAR. MATERIALS AND METHODS: All published articles regarding DIC post-EVAR were identified from 3 major databases and analyzed...

BACKGROUND: In-stent restenosis remains a common and important complication after endovascular treatment of superficial femoral artery peripheral artery disease. It occurs in 14 to 35% of cases in 1 year and there is still no efficient treatment for this condition. Paclitaxel-coated balloons have shown promising results. OBJECTIVE: Investigate the 3 year results of superficial femoral artery in-stent restenosis treated with paclitaxel-coated balloon angioplasty, using the Lutonix™ 035 device...

PURPOSE: Hepatic arterioportal fistula (HAPF) is an uncommon complication of hepatic trauma, which can manifest with abdominal pain and the sequelae of portal hypertension months to years after injury. The purpose of this study is to present cases of HAPF from our busy urban trauma center and make recommendations for management. METHODS: One hundred and twenty-seven patients with high-grade penetrating liver injuries (American Association for the Surgery of Trauma [AAST] - Grades IV-V) between January 2019 and October 2022 were retrospectively reviewed...

Cystic adventitial disease (CAD) is a rare vascular disorder predominantly seen in adults without cardiovascular risk factors. We report a case of CAD involving the common femoral vein in a 38-year-old female presented with right lower extremity swelling that was initially misdiagnosed as deep vein thrombosis (DVT). A computed tomography revealed a cystic structure that compressed the right common femoral vein with resultant severe stenosis of the vascular lumen. Complete evacuation of the cyst with excision of the cyst wall was performed, and the patient remained symptom-free at 3 year follow-up...

We describe the successful n -butyl cyanoacrylate (NBCA) packing of a large gastroduodenal artery pseudoaneurysm after distal pancreatectomy in a patient with a history of subtotal esophagectomy and gastric tube reconstruction. The pseudoaneurysm was considered to be caused by direct injury to the gastroduodenal artery (GDA). However, embolization of the GDA was not possible in this case because due to prior esophageal surgery, the main blood vessel supplying the gastric tube was the right epigastric artery from the GDA...

OBJECTIVE: Assess heterogeneity within patients with resolved COVID-19 to broaden the vision about post-discharge thrombotic cases and postulate possible related mechanisms in search of better anticoagulation guidelines. This study details patients' characteristics, medical history, treatment, and outcomes of readmitted patients with late acute thrombosis through a systematic review of the literature and patients from our academic center database. METHODS: We extracted the records of patients readmitted for venous thrombosis complications after discharge from the database of the first 2000 patients admitted with COVID-19 in our academic center; we also performed a systematic review of the literature using the Medical Subject Headings terms "late thrombosis," "COVID-19," + "venous thrombosis" in PubMed and Google Scholar according to PRISMA guideline...

We report an unusual case of a 40-year-old male patient who experienced painful swelling of the left lower limb that persisted for 1 week. Imaging modalities not only confirmed the diagnosis of acute iliofemoral venous thrombosis and pulmonary embolism (PE), but also an incidental finding of interrupted inferior vena cava (IVC). This congenital anomaly is uncommon but rarely associated with venous thromboembolism (VTE). The azygos continuation was compressed by the descending aorta against the 11th thoracic vertebrae, which was identified as the cause of VTE...

OBJECTIVE: Iatrogenic injury to the large abdominopelvic veins can he highly morbid, and open surgical repair is technically challenging. Endovascular repair with covered stenting across the injured segment offers an alternative to open surgical management. We present a series of patients with operative injury to the inferior vena cava (IVC) and iliac veins who were treated utilizing an endovascular approach and review the available literature on this technique. METHODS: A PubMed keyword and MeSH term search was performed, and titles were reviewed for relevance by the first author...

INTRODUCTION: Spontaneous iliac vein rupture is a rare, but frequently lethal condition. It is important to timely recognize its clinical features and immediately start adequate treatment. We aimed to increase awareness to clinical features, specific diagnostics, and treatment strategies of spontaneous iliac vein rupture by evaluating the current literature. METHODS: A systematic search was conducted in EMBASE, Ovid MEDLINE, Cochrane, Web of Science, and Google Scholar from inception until January 23, 2023, without any restrictions...

BACKGROUND: The use of Hyperbaric Oxygen Therapy (HBOT) in diabetic wounds has been studied extensively. Even though venous insufficiency is the most common cause of lower limb ulceration, there is comparatively little evidence regarding the use of HBOT for Venous Leg Ulcers (VLU). We performed a systematic-review to evaluate and synthesise available evidence, to evaluate whether patients with VLU, when treated with HBOT, had greater rates of (i) complete VLU healing or (ii) reduction in VLU area, than controls...

INTRODUCTION: Congenital malformations of the inferior vena cava are rare and remain an under recognised cause of spontaneous deep venous thrombosis (DVT). The purpose of this case report is to highlight the rare occurrence of a concomitant iliac vein aneurysm and the feasibility of endovascular reconstruction in the presence of extensive iliocaval thrombus burden, especially in cases where other treatment modalities have been unsuccessful. REPORT: This is the report of a 25-year-old male who presented with acute onset left lower limb pain/swelling secondary to extensive iliocaval DVT...

Objective: This study aims to evaluate the use of prophylactic intravenous hydration (IV prophylaxis) and carbon dioxide (CO2 ) angiography in reducing contrast associated-acute kidney injury (CA-AKI) and determine the overall incidence and risk factors of CA-AKI in high-risk patients undergoing peripheral vascular interventions (PVI). Method: Only patients undergoing elective PVI from 2017 to 2021 with chronic kidney disease (CKD) stage 3-5 in the Vascular Quality Initiative (VQI) database were included. Patients were grouped into IV prophylaxis vs no prophylaxis...

OBJECTIVE: Recanalization of flush ostial superficial femoral artery (SFA) occlusion is a very challenging procedure. Using the ipsilateral antegrade approach in such lesions has some difficulties. This study aimed to assess the feasibility, efficacy, and outcomes of duplex-guided ipsilateral antegrade access for endovascular treatment of atherosclerotic flush occlusion of the SFA. METHODS: This is a prospective two-center study that included chronic lower extremity ischemia patients with flush occlusion of SFA who underwent duplex-guided ipsilateral antegrade endovascular revascularization due to unfeasible contralateral femoral approach...
