REVIEW
Aparna Annam
Vascular malformations are classified primarily according to their flow characteristics, slow flow (lymphatic and venous) or fast flow (arteriovenous). They can occur anywhere in the body but have a unique presentation when affecting the female pelvis. With a detailed clinical history and the proper imaging studies, the correct diagnosis can be made and the best treatment can be initiated. Lymphatic and venous malformations are often treated with sclerotherapy while arteriovenous malformations usually require embolization...

#3
REVIEW
Eric DePopas, Matthew Brown
Lower extremity venous insufficiency and varicose veins are common conditions, affecting up to 25% of women. Herein, we review the pathophysiology of lower extremity venous insufficiency and varicose veins, the epidemiology of varicose veins, clinical diagnosis, and ultrasonographic diagnosis. We also discuss treatment rationale, algorithms, and techniques, with a focus on endovenous great saphenous vein ablation.

Uterine fibroids (leiomyomas) are the most common benign neoplasm of the female pelvis and have a lifetime prevalence exceeding 80% among African American women and approaching 70% among Caucasian women. Approximately 50% of women with fibroids experience symptoms which may include menorrhagia that may result in anemia, bulk symptoms with bladder and bowel dysfunction and abdominal protrusion, dysmenorrhea, and infertility. Hysterectomy remains the most common treatment option for fibroids and concerns have been raised about the overuse of this procedure...

REVIEW
Jonathan D Lindquist, Robert L Vogelzang
Postpartum hemorrhage (PPH) is the leading cause of maternal perinatal morbidity and mortality worldwide. Defined as greater than 500 mL blood loss after vaginal delivery, and greater than 1,000 mL blood loss after cesarean delivery, PPH has many causes, including uterine atony, lower genital tract lacerations, coagulopathy, and placental anomalies. Correction of coagulopathy and identification of the cause of bleeding are mainstays of treatment. Medical therapies such as uterotonics, balloon tamponade, pelvic artery embolization, and uterine-sparing surgical options are available...

Pelvic venous insufficiency is now a well-characterized etiology of pelvic congestion syndrome (PCS). The prevalence of CPP is 15% in females aged 18 to 50 years in the United States and up to 43.4% worldwide. In addition to individual physical, emotional, and quality-of-life implications of CPP, there are profound healthcare and socioeconomic expenses with estimated annual direct and indirect costs in the United States in excess of 39 billion dollars. PCS consists of clinical symptoms with concomitant anatomic and physiologic abnormalities originating in venous insufficiency...

Breast cancer is the most common women's malignancy in the United States and is the second leading cause of cancer death. More than half of patients with breast cancer will develop hepatic metastases; this portends a poorer prognosis. In the appropriately selected patient, there does appear to be a role for curative (surgery, ablation) or palliative (intra-arterial treatments) locoregional therapy. Gynecologic malignancies are less common and metastases to the liver are most often seen in the setting of disseminated disease...

REVIEW
Salina Zhang, Pelin Batur, Charles Martin, Paul J Rochon
As the reversible contraceptive arm implants grow more popular, there is an increasing need to recognize the complications resulting from implant migration and removal. This review summarizes the findings of imaging and removal methods. When an implant is lost, the axillary region should be investigated first. If the implant still cannot be found, visualization though different methods have been employed for non-radiopaque implants. Real-time fluoroscopic-guided localization and removal can be accomplished for radiopaque Nexplanon...

REVIEW
Divya Sridhar, Maureen P Kohi
Magnetic-resonance-guided focused ultrasound (MRgFUS), also called high-intensity focused ultrasound (HIFU) is an effective, noninvasive uterine-preserving treatment for symptomatic uterine fibroids. As the use of this therapeutic modality is not yet widespread, it may remain unfamiliar to many interventional radiologists. The purpose of this review is to discuss MRgFUS, including technology, patient selection, technique, outcomes, complications, and recent data on fertility and comparative effectiveness.

REVIEW
Kristofer Schramm, Paul J Rochon
In the past 20 years, peripheral artery disease (PAD) has been increasingly recognized as a significant cause of morbidity and mortality in the United States. PAD has traditionally been identified as a male-dominant disease; however, recent population trends and studies in PAD suggest that women are affected at least as often as men. Women comprise a larger population of the elderly than men, as well as an increasing proportion of patients with PAD. Much of the existing research on PAD has focused on whole populations, and gender-specific data on PAD is sparse...

REVIEW
Rulon L Hardman
Chronic deep vein thrombosis (DVT) affects hundreds of thousands of women in the United States. Chronic DVT can lead to pain, edema, venous ulcers, and varicosities. While there are limited data regarding the management of chronic DVT, several interventional radiology groups aggressively treat chronic DVT to aid patient symptom resolution. Recanalization of occluded veins and venous stenting re-establishes deep vein flow and decreases venous hypertension.

REVIEW
Eric Wannamaker, Kimi Kondo, D Thor Johnson
Heparin-induced thrombocytopenia and thrombosis (HITT) is an under-recognized cause of deep venous thrombosis treatment failure and of complications during catheter-directed thrombolysis. After a review of HITT pathophysiology, diagnosis, and management, three different cases are presented in this article. Each case highlights subtleties and challenges of HITT diagnosis and management. An example of a practical approach to the diagnosis of HITT is presented.

Venous obstruction in the cancer population can result in substantial morbidity and, in extreme cases, mortality. While venous obstruction can be caused by both benign and malignant etiologies in this population, the management of malignant venous obstruction as a palliative measure can be somewhat nuanced with respect to nonprocedural and procedural management, both with respect to treatment of the underlying malignancy as well as treatment of venous hypertension, which may be associated with venous thrombosis...

Bleeding is a common and often challenging complication of malignancy. Etiologies of hemorrhage in this patient population vary, and bleeding may present as an acute, life-threatening emergency or a chronic, low-volume blood loss. For patients with advanced malignancies, interventions to manage bleeding must be balanced by the patient's life expectancy and quality of life. As such, minimally invasive procedures such as transarterial embolization are useful therapeutic options in appropriately selected patients...

Chronic upper abdominal pain occurs as a complication of various malignant and benign diseases including pancreatic cancer and chronic pancreatitis, and when present may contribute to lower quality of life and higher mortality. Though various pain management strategies are available as part of a multimodal approach, they are often incompletely effective and accompanied by side effects. Pain originating in upper abdominal viscera is transmitted through the celiac plexus, which is an autonomic plexus located in the retroperitoneum at the root of the celiac trunk...

REVIEW
Jeffrey H Lee, Tomas DaVee
Painless jaundice is a harbinger of malignant biliary obstruction, with the majority of cases due to pancreatic adenocarcinoma. Despite advances in treatment, including improved surgical techniques and neoadjuvant (preoperative) chemotherapy, long-term survival from pancreatic cancer is rare. This lack of significant improvement in outcomes is believed to be due to multiple reasons, including the advanced stage at diagnosis and lack of an adequate biomarker for screening and early detection, prior to the onset of jaundice or epigastric pain...

REVIEW
Amy R Deipolyi, Anne M Covey
The optimal palliative intervention for malignant biliary obstruction is internal drainage by placement of a metallic stent. For patients with hilar biliary obstruction or low bile duct obstruction in whom endoscopy is not feasible, a percutaneous transhepatic approach in interventional radiology is preferred. This article reviews the rationale for this approach, periprocedural management, and techniques to optimize stent patency.

Zoe A Miller, Prasoon Mohan, Robert Tartaglione, Govindarajan Narayanan
Over the past 30 years, image-guided placement of gastrostomies and cecostomies for gastrointestinal decompression has developed into a safe and effective treatment for symptomatic bowel obstruction. Gastrostomies and cecostomies relieve patient symptoms, can prevent serious complications such as colonic perforation, and may bridge patients to more definitive treatment for the underlying cause of obstruction. This article will review the history of decompressive gastrostomies and cecostomies as well as the indications, contraindications, technique, complications, and outcomes of these procedures...

REVIEW
Hooman Yarmohammadi, George I Getrajdman
Ascites causes significant discomfort and has negative impact on patient's quality of life. Medical therapies including dietary restriction and diuretics are successful in only 40 to 44% of patients with malignant ascites and repeated paracentesis only provides temporary symptomatic relief. Therefore, a more permanent solution is necessary. Indwelling catheters or peritoneovenous shunt placement can provide more permanent symptomatic relief and improve patients' quality of life. Unlike indwelling catheters, peritoneovenous shunts do not limit patients' life style and therefore should be offered as first option in patients who are good candidates...
