Treatment of pregnancy-related venous thromboembolism is limited by considerations of the health risks to both the patient and fetus. Anticoagulation is the cornerstone treatment for pregnancy-related venous thromboembolism; however, early thrombus removal may be preferred for prompt symptom resolution and to decrease the risk of post-thrombotic syndrome. We report the successful treatment of a patient in the second trimester of pregnancy with symptomatic iliofemoral deep venous thrombosis and May-Thurner syndrome using percutaneous mechanical thrombectomy.

A type A aortic dissection is a challenging condition for both cardiothoracic and vascular surgeons. Although open surgery remains the gold standard, there is considerable interest in the use of endovascular techniques for patients who present with malperfusion. We present the case of an unstable 55-year-old man with visceral malperfusion from a type A dissection who was stabilized using an endovascular technique as a bridge to open surgery. A bare metal thoracic endograft was used in the ascending aorta to rapidly restore perfusion. This hybrid approach to the problem of malperfusion in type A dissection could be useful for these patients with complicated cases.

Endovascular revascularization with intraluminal stenting is the recommended first-line therapy for chronic mesenteric ischemia. However, early recurrence and in-stent thrombosis remain significant challenges. We present the case of a patient with recurrent chronic mesenteric ischemia secondary to in-stent restenosis that was successfully treated with intravascular lithotripsy, a novel, safe approach to stent salvage.

Arteriovenous fistula is a rare and often unrecognized complication of aneurysms, with a varied and frequently inconsistent presentation. We present the case of an ilio-iliac arteriovenous fistula formation in a 71-year-old man associated with a type III endoleak after endovascular iliac branch repair. Because of rapidly progressing congestive heart failure and hepatorenal syndrome, we performed urgent endovascular repair with successful endoleak exclusion. After the procedure, the patient demonstrated a remarkably rapid and complete recovery.

Aortic mural thrombus in the absence of underlying aortic disease is rare and results in a risk of distant arterial embolization that can result in limb loss or other end organ damage. Current management involves open surgery, anticoagulation, and systemic thrombolysis; however, each carries inherent risks. We report the case of aortic thrombus with distal emboli in two patients, a 56-year-old man and a 68-year-old man, neither with underlying aortic pathology and both presenting with limb threatening ischemia. We performed percutaneous mechanical thrombectomy using the FlowTriever System (Inari Medical, Irvine, Calif) with successful removal of the aortic thrombus in both patients.

Deep vein thrombosis is relatively rare in the pediatric setting, though it carries significant risk for pulmonary embolism and post-thrombotic syndrome. We report a case of a 10-year-old girl diagnosed with pulmonary embolism and right iliofemoral vein deep vein thrombosis with concomitant granulomatosis with polyangiitis (formerly Wegener's granulomatosis) and acute glomerulonephritis. Owing to lifestyle-limiting venous claudication, we performed percutaneous, mechanical thrombectomy using the ClotTriever system with successful removal of likely both acute and chronic thrombus. After the procedure, the patient had near complete resolution of her venous claudication symptoms.

The novel coronavirus 2019 (SARS-CoV-2) was first identified in January 2020 and has since evolved into a pandemic affecting >200 countries. The severity of presentation is variable and carries a mortality between 1% and 3%. We continue to learn about the virus and the resulting acute respiratory illness and hypercoagulability; however, much remains unknown. In our early experience in a high-volume center, we report a series of four cases of acute peripheral artery ischemia in patients with COVID-19 in the setting of elevated D-dimer levels.

New York City was one of the epicenters of the COVID-19 pandemic. The management of peripheral artery disease (PAD) during this time has been a major challenge for health care systems and medical personnel. This document is based on the experiences of experts from various medical fields involved in the treatment of patients with PAD practicing in hospitals across New York City during the outbreak. The recommendations are based on certain aspects including the COVID-19 infection status as well as the clinical PAD presentation of the patient. Our case-based algorithm aims at guiding the treatment of patients with PAD during the pandemic in a safe and efficient way.
