Midterm changes in iliac limb apposition after endovascular aortic aneurysm repair.

Background: Literature is scarce on the course of iliac endograft limb apposition after endovascular aortic aneurysm repair (EVAR), which is why this study was conducted.

Methods: A retrospective observational imaging study was performed to measure iliac apposition of endograft limbs on the first post-EVAR computed tomography angiography (CTA) scan and on the latest available follow-up CTA scan. With center lumen line reconstructions and CT-applied dedicated software, the shortest apposition length (SAL) of the endograft limbs was assessed as well as the distance between the end of the fabric and the proximal border of the internal iliac artery or the endograft-internal artery distance (EID).

A Statistical Shape Model of Infrarenal Aortic Necks in Patients With and Without Late Type Ia Endoleak After Endovascular Aneurysm Repair.

Purpose: Hostile aortic neck characteristics, including short length, severe suprarenal and infrarenal angulation, conicity, and large diameter, have been associated with increased risk for type Ia endoleak (T1aEL) after endovascular aneurysm repair (EVAR). This study investigates the mid-term discriminative ability of a statistical shape model (SSM) of the infrarenal aortic neck morphology compared with or in combination with conventional measurements in patients who developed T1aEL post-EVAR.

Materials And Methods: The dataset composed of EVAR patients who developed a T1aEL during follow-up and a control group without T1aEL.

A Statistical Shape Model of the Morphological Variation of the Infrarenal Abdominal Aortic Aneurysm Neck.

Hostile aortic neck characteristics, such as short length and large diameter, have been associated with type Ia endoleaks and reintervention after endovascular aneurysm repair (EVAR). However, such characteristics partially describe the complex aortic neck morphology. A more comprehensive quantitative description of 3D neck shape might lead to new insights into the relationship between aortic neck morphology and EVAR outcomes in individual patients.

Endograft apposition and infrarenal neck enlargement after endovascular aortic aneurysm repair.

Background: Sufficient apposition and oversizing of the endograft in the aortic neck are both essential for durable endovascular aneurysm repair (EVAR). These measures are however not regularly stated on post-EVAR computed tomography angiography (CTA) scan reports. In this study endograft apposition and neck enlargement (NE) after EVAR with an Endurant II(s) endograft were analyzed and associated with supra- and infrarenal aortic neck morphology.

Remodeling of Abdominal Aortic Angulation and Curvature After Endovascular Aneurysm Repair in Patients With vs Without Late Type Ia Endoleak or Endograft Migration.

Purpose: To investigate aortic remodeling of the supra- and infrarenal aorta from preoperative to 1 month and midterm follow-up after endovascular aneurysm repair (EVAR) by analyzing changes in angulation and curvature in patients with vs without late type Ia endoleak or device migration.

Materials And Methods: From a multicenter database, 35 patients (mean age 76±5 years; 31 men) were identified with late (>1 year) type Ia endoleak or endograft migration (≥10 mm) and defined as the complication group. The control group consisted of 53 patients (mean age 75±7 years; 48 men) with >1-year computed tomography angiography (CTA) follow-up and no evidence of endoleaks.

Arterial thrombotic complications in COVID-19 patients.

The coronavirus disease 2019 (COVID-19), a viral respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been described to predispose to thrombotic disease in both the venous and arterial circulations. We report four cases of an acute arterial occlusion in COVID-19 patients and literature review on the occurrence of arterial thrombosis in patients with COVID-19. Our findings demonstrate that physicians should be vigilant for signs of thrombotic complications in both hospitalized and new COVID-19 patients.

Outcomes of open repair of postdissection abdominal aortic aneurysms.

Background: Evidence to guide management of postdissection abdominal aortic aneurysms (PDAAA) is lacking. This study describes the outcomes of open repair of PDAAA.

Methods: A retrospective cohort study was conducted of all consecutive patients treated with open repair for PDAAA after a Stanford type A or type B thoracic aortic dissection between January 2006 and December 2017 in two vascular referral centers.

Apposition and Positioning of the Nellix EndoVascular Aneurysm Sealing System in the Infrarenal Aortic Neck.

Purpose: To investigate the initial proximal position and seal of the Nellix EndoVascular Aneurysm Sealing (EVAS) system in the aortic neck using a novel methodology.

Methods: Forty-six consecutive patients who underwent elective EVAS for an abdominal aortic aneurysm were retrospectively selected and dichotomized into an early (n=23) and a late (n=23) group. The aortic neck morphology and aortic neck surface (ANS) were determined on preoperative computed tomography (CT) scans; the endograft position and nonapposition surface (NAS) were determined on the 1-month CT scans.

Popliteal artery aneurysms differ from abdominal aortic aneurysms in cellular topography and inflammatory markers.

Objective: Popliteal artery aneurysms (PAAs) and abdominal aortic aneurysms (AAAs) frequently coincide; however, symptoms differ. We systematically assessed aneurysm cellular wall composition and inflammatory markers to compare both anatomic locations.

Methods: Aneurysmal walls of 38 PAAs and 198 AAAs were harvested from patients undergoing elective open surgical repair.

Association of sex with long-term outcomes after popliteal artery aneurysm repair.

Background: We compared initial and long-term outcomes between men and women after endovascular and open repair of popliteal artery aneurysms (PAAs).

Methods: Between January 1993 and July 2011, 202 patients (185 men [92%]), underwent open (n = 186) or endovascular (n = 16) repair of a PAA. Data were retrospectively analyzed.

Variations in anatomy of the popliteal artery and its side branches.

Knowledge of anatomic variations of the popliteal artery is essential for the management of peripheral vascular disease and in orthopedic surgery. The aim of this study was to perform an overview of the literature describing variations of the popliteal artery. To identify relevant literature, we performed a systematic search on MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews.

Treatment of impacted greenstick forearm fractures in children using bandage or cast therapy: a prospective randomized trial.

Background: To evaluate the relative risks and advantages of using soft bandage therapy (BT) for impacted greenstick fractures of the distal forearm compared with cast therapy (CT).

Methods: At a single center from September 2005 to October 2006 all patients with an impacted greenstick fracture were randomized to BT or CT.

Results: A total of 92 patients were randomized and assigned.

Surgical repair of a gunshot injury to the left carotid artery: case report and review of literature.

We present a case of a 37-year-old man who sustained a single gunshot wound (penetrating zones I and II) and internal carotid artery injury. Optimal evaluation and management of vascular injury remains controversial. Literature on the operative techniques of carotid artery injuries is reviewed.

The medial versus the posterior approach in the repair of popliteal artery aneurysms: a multicenter case-matched study.

Objectives: This study was conducted to compare the early and mid-term results of the medial and posterior approaches in the surgical treatment of popliteal artery aneurysms (PAAs).

Methods: From 1992 to 2006 in three hospitals, 110 popliteal aneurysms needed surgical repair by a posterior or a medial approach. Of 36 aneurysms repaired by the posterior approach, 33 could be case-matched to a medially excluded PAA according to the criteria of (1) patient age, (2) cardiovascular comorbidity, (3) indication for PAA repair, (4) diameter of PAA at time of surgical repair, (5) number of distal outflow vessels at time of surgical repair, and (6) type of bypass or interposition graft (venous or polytetrafluoroethylene).
