Preoperative Direct Puncture Embolization Using a Nonadhesive Ethylene Vinyl Alcohol (EVOH) Liquid Embolic Agent for Head and Neck Paragangliomas.

Purpose: This retrospective study aimed to assess the safety and technical efficacy of preoperative direct puncture embolization using a nonadhesive ethylene vinyl alcohol (EVOH) copolymer-based liquid embolic agent (LEA) combined with balloon occlusion at the origin of the external carotid artery for head and neck paragangliomas (HNP).

Methods: We conducted a review of all consecutive cases of HNPs treated with direct puncture embolization using EVOH-based LEAs between 2017 and 2022 in 2 tertiary high-volume hospitals.

Results: A total of 25 cases of HNPs in 24 patients underwent direct puncture embolization (12 males, 12 females, mean age 50.

Chimney endovascular aneurysm repair-induced mesenteric ischemia: a report of an extremely rare complication.

The chimney endovascular aneurysm repair (Ch-EVAR) technique has progressively increased in popularity in the treatment of complex aortic aneurysms. However, the long-term results of this technique still must be assessed, especially in comparison to custom-made solutions. The patency of chimney grafts has always been one of the important issues with the Ch-EVAR technique.

Severe local wound infections after vascular exposure in the groin and other body areas: Prevention, treatment and prognosis.

Severe surgical site infections (SSIs) are a frequent nosocomial complication after vascular interventions, an important cause of postoperative morbidity, and a substantial burden to the health care system. Patients undergoing arterial interventions are at elevated risk of SSIs, possibly because of the presence of several risk factors in this patient population. In this review, we examined the available clinical evidence for the prevention, treatment, and prognostication of postoperative severe SSIs after vascular exposure in the groin and other body areas.

Horseshoe Kidney Protection with Histidine-Tryptophan-Ketoglutarate Solution during Surgical Abdominal Aortic Aneurysm Repair.

Case Report: We report an unusual case of a 65-year-old male patient with horseshoe kidney, who underwent a successful open repair for an abdominal aortic aneurysm (AAA). The accessory renal arteries were perfused with histidine-tryptophan-ketoglutarate (HTK) solution (Custodiol®; Dr. Franz-Kohler Chemie GmbH, Bensheim, Germany) during the vascular reconstruction.

Management of Iatrogenic Bladder Injury due to Vascular Surgery: Case Report and Literature Review.

We report an unusual case of a 53-year-old male patient, previously undergone an extra-anatomic right-to-left iliofemoral bypass graft, who has developed gross hematuria after 4 months. The cystoscopic examination revealed a wall injury due to the presence of the graft crossing the bladder. Iatrogenic bladder injuries during vascular surgery are extremely rare.

Cerebrovascular Insufficiency from Radiation-Induced Progressive Obstruction of Supra-Aortic Vessels.

Background: Radiation therapy may accelerate atherosclerosis with progressive stenosis and occlusions of supra-aortic trunks.

Methods And Results: We report the case of a 44-year-old woman with radiation-induced occlusion of the supra-aortic trunks presenting with recurrent cerebrovascular insufficiency after an unusual surgical revascularization technique (retrograde femoral-axillary bypass) performed for late failure of previous endovascular treatment.

Conclusions: Customized surgical procedure can be considered as a bailout to improve cerebral blood inflow in selected cases.
