Background: Symptomatic Pelvic Congestion Syndrome (PCS) is often underdiagnosed and undertreated. We investigate a symptoms-based screening algorithm and treatment algorithm focused on position and location of pain for each type of PCS. Methods: This study is a retrospective, single-institution, multi-site review of 343 female patients who presented with pelvic pain. Results: Following a symptoms-based algorithm, 302 patients fulfilled criteria for inclusion; 299 patients had positional symptoms with a positive predictive value (PPV) of 97.99%, sensitivity of 98.99% and Odds Ratio (OR) of 48.83 (p=0.0003) while duplex ultrasonography (DUS) had a PPV of 98.84%, sensitivity of 86.49%, and OR of 6.4 (p=0.0396) confirmed by contrast venography. Patients with Type I PCS were treated with embolization and 87.5% reported total relief of anterior symptoms. Patients with Type II PCS were treated with embolization and/or vascular stenting based on their associated lesion, May-Thurner syndrome or Nutcracker syndrome, and 88.54% reported ≥50% symptom relief and 59.03% reported ≥80% symptom relief. Full treatment resulted in a mean “overall satisfaction” score of 96.07%. Conclusions: Algorithmic approaches are essential for PCS evaluation, diagnosis, and treatment. Patients with positional pelvic symptoms consistent with PCS should undergo diagnostic venography. Distinguishing between the types of PCS and using symptoms as a guide may be beneficial over a “one-size-fits-all” approach.
Background: Osteoarthritis (OA) of the knee is an inflammatory joint disorder of the cartilage, joint capsule, synovium, and surrounding bone. Intraarticular inflammation induces angiogenesis leading to pain and inflammation. Research suggests a relationship between patients with osteoarthritis of the knee and venous insufficiency or contributing arteriovenous malformations (AVMs). Similar to genicular artery embolization (GAE), transvenous or transmalformation cannulation and embolization offers a minimally invasive treatment modality for patients with mild to moderate osteoarthritis. Case presentations: Here, we present the successful treatment of OA of the knee using direct puncture transmalformation cannulation and embolization in five patients. Direct puncture, a technique used to embolize peripheral AVMs, is a safe, less invasive method for the treatment of osteoarthritis with associated AVMs. Conclusions: For patients with OA-related knee pain and associated AVMs, the advancement of endovascular techniques offers alternative approaches to the treatment of mild to moderate OA. Direct puncture and transmalformation cannulation and embolization reduce the risk of intra- and post-operative complications, improve recovery time, and minimize operating time and operating costs. In review of the literature, this is one of the first published reports describing the use of direct puncture transvenous or transmalformation cannulation and embolization to treat OA-related pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
