Vascular lesions have a varied appearance and can commonly occur in the head and neck. A majority of these lesions are cutaneous and congenital; however, some may be acquired and malignant. The presentation and clinical history of patients presenting with head and neck lesions can be used to guide further imaging, which can provide important diagnostic and therapeutic considerations. This review discusses the revised International Society for the Study of Vascular Anomalies (ISSVA) classification system for vascular tumors and malformations, as well as explores the most common vascular anomalies including their clinical presentations and imaging findings.

Er blunt trauma from January 2011 to June 2019. Results: Sixty patients underwent angiography for splenic injury after blunt traumatic injury. Forty-four patients were embolized. Seventeen patients underwent proximal SAE, and 23 underwent distal SAE. Four patients had a combination of proximal and distal SAE. Eleven patients had subsequent major complications requiring splenectomy. There was no significant difference in major complication rate when comparing proximal SAE 29.4% versus distal SAE 21.7%. No significant difference was noted across the two groups with respect to age or grade of injury. There was a statistically significant difference (P = 0.004) in fluoroscopy time between the proximal 10.1 ± 4.2 min and distal group 17.8 ± 8.7 min. No statically significant difference was found in major complications when comparing coil versus gel foam embolization. Conclusion: Proximal SAE is associated with a significantly lower fluoroscopy time (P = 0.004). Complication rates are similar after proximal and distal SAE. No significant difference was found in major complication rates comparing coil versus gel foam embolization. Minor complications more commonly occurred after proximal embolization with gel-foam....

Objective: To determine, time to angiography for patients with positive gastrointestinal bleeding (GIB) on prior investigation (endoscopy [ES], nuclear medicine [NM] Tc99m red blood cells (RBC) scan, or computed tomography angiography), affects angiographic bleed identification. Materials and Methods: Visceral Angiograms performed from January 2012 to August 2017 were evaluated. Initial angiograms performed for GIB were included in the study. Exclusion criteria included recent abdominal surgery or procedure (30 days), empiric embolization (embolization without visualized active bleeding), and use of vasodilators, or subsequent angiogram. Timing and results of ES, NM Tc99m RBC scan, or computed tomography angiogram and catheter angiogram were recorded. In addition, age, gender, angiogram time, anti- platelet therapy, anti-coagulation therapy, bleed location, international normalized ratio, and units of packed RBCs received in the 24 h before catheter angiography were included in the study. Results: One hundred and seventy angiograms were included in the final analysis. Forty-three angiograms resulted in the identification of an active bleed (68.9 years, and 67.4% male). All of these patients were embolized successfully. One hundred and twenty-seven angiograms failed to identify an active bleed (70.4 years, and 49.6% male). No significance was found across the two groups with respect to time from prior positive investigation. Receiver operating characteristic analysis demonstrated that units of packed RBCs received in the preceding 24 h were correlated with positive bleed identification on catheter angiography. Conclusion: Time to angiography from prior positive investigation, including ES, NM Tc99m RBC scan, or computed tomography angiogram does not correlate with positive angiographic outcomes. Increasing units of packed RBCs administered in the 24 h before angiogram do correlate with positive angiographic findings.
Gastrointestinal manifestations of post-transplant lymphoproliferative disorder (GI-PTLD) encompasses a spectrum of mucosal inflammation and ulceration that can present as severe acute gastrointestinal bleed. This case report describes a case of GI-PTLD in a 19-year-old female status postcardiac transplant. This patient presented with extensive gastrointestinal hemorrhage secondary to PTLD involving the duodenum. The patient was treated with extensive embolization of the gastroduodenal artery and the pancreaticoduodenal arcades. Embolization was used to mitigate gastrointestinal bleeding, thus preventing the need for surgical resection and extensive reconstruction. This case report demonstrates the utility of embolization as potential therapeutic option in the setting of GI-PTLD in addition to medical and endoscopic therapy.

Objective: The objectives of this study were to identify the causes of internal jugular vein (IJV) blood flow reversal revealed on ultrasound imaging. Methods: In this retrospective review, 4796 upper extremity venous ultrasounds completed at a single institution between January 2012 and December 2017 were reviewed to identify cases of flow reversal in the IJV. Fourteen patients were identified with IJV flow reversal. Medical charts of these 14 patients were reviewed to identify the etiology of blood flow reversal. Results: Intraluminal causes were the most common and were most frequently seen in patients with vascular damage secondary to placement of endovascular devices. Flow reversal most commonly occurred in the left IJV and was equally represented in men and women. Ages ranged from 41.38 to 82.76 years, with an average age of 61.92 years. Conclusion: Reversal of flow in the IJV is a rare finding which is most often diagnosed on ultrasound evaluation of the upper extremity. Further investigation should be performed when flow reversal is identified, as the underlying cause may have serious clinical implications.
