Open Endoaneurysmorrhaphy of 9-cm Ruptured Popliteal Aneurysm 7 Years after Initial Repair.

BACKGROUND: A previously repaired right popliteal artery aneurysm via a medial approach with proximal and distal ligation and interval bypass re-presented 7 years after the initial repair with a ruptured 9 × 25.5 cm right popliteal aneurysm. METHODS: Surgical repair was complex due to the large size of the aneurysm. Technique and management of popliteal aneurysm repair are discussed, along with a review of the current literature. RESULTS: A 58-year-old male with a 3.5 cm popliteal artery aneurysm was initially treated with end-to-end prosthetic bypass and proximal/distal aneurysm ligation from a medial-approach without complication. Seven years later, he presented with a 9-cm popliteal aneurysm rupture. Posterior approach endoaneurysmorrhaphy repair was far more complicated than expected with massive blood loss. Despite this, he was discharged without complication POD #5, but on POD #19 presented with cellulitis and underwent incision and drainage of retained hematoma with cultures positive for Strep dysgalactiae. With appropriate treatment, he was healed in 3 months. CONCLUSIONS: Surgical repair of large popliteal aneurysms can be challenging, but continued aneurysmal degeneration is a potential consequence if the sac continues to be pressurized from patent geniculate arteries. Surgical repair of large popliteal artery aneurysms is complex and requires adjunctive techniques to maximize success. A posterior approach is described and the literature reviewed to support recommendations for primary popliteal artery aneurysm repair and repair of large degenerated popliteal artery aneurysms. We recommend primary popliteal artery aneurysm repair from a posterior approach with endoaneurysmorrhaphy and an interposition bypass. For ruptured large popliteal artery aneurysms, there is a high risk of hemorrhage and wound complications. Therefore, we recommend the use of a tourniquet, surgical drain and to consider the collection of intraoperative cultures to guide potential antibiotic management.

Adventitial cystic disease in the external iliac artery of a 29-year-old man.

Adventitial cystic disease (ACD) is an uncommon condition that generally occurs at the popliteal artery but, rarely, can occur in the external iliac artery. To date, only eight cases of ACD occurring in the external iliac artery have been reported. We have reported the case of a 29-year-old man who had presented with new-onset claudication. Despite an extensive imaging workup, ACD was not confirmed until the gross intraoperative examination. We have reported our process of diagnosis and treatment in addition to that reported in previous studies to enhance the historical fund of knowledge for this rare pathology.

Ruptured abdominal aortic aneurysm repair in pediatric Marfan syndrome patient.

Marfan syndrome is a well-described autosomal dominant connective tissue disorder with a constellation of anatomic characteristics including aortic degeneration as a result of the spontaneous mutation of the fibrillin gene, FBN1. Whereas life-threatening dissection and ascending aneurysmal rupture have been thoroughly documented in the literature, aneurysms of the abdominal aorta and those present in the pediatric population have only rarely been reported. In this case report, we describe presentation, successful open surgical repair, and recovery of a pediatric Marfan syndrome patient with a ruptured abdominal aortic aneurysm.

Thoracic sympathectomy for upper extremity ischemia.

INTRODUCTION: Thoracic sympathectomy is performed in the management of a variety of disorders of the upper extremity. To evaluate the contemporary results of thoracic sympathectomy for upper extremity ischemia a systematic review of the literature was conducted. EVIDENCE AQUISITION: We performed a PubMed, EMBASE and Cochrane search of the literature written in the English language from January 1975 to December 2015. All articles presenting original patient data regarding the effect of treatment on symptoms or on the healing of ulcers were eligible for inclusion. Individual analyses for Primary Raynaud's Disease (PRD) and Secondary Raynaud's Phenomenon (SRP) were performed. EVIDENCE SYNTHESIS: We included 6 prospective and 23 retrospective series with a total of 753 patients and 1026 affected limbs. Early beneficial effects of thoracic sympathectomy were noticed in 63-100% (median 94%) of all patients, in 73-100% (median 98%) of PRD patients and in 63-100% (median 94%) of SRP patients. The beneficial effect was noted to lessen over time. Long-term beneficial effects were reported in 13-100% (median 75%) of all patients, in 22-100% (median 58%) of PRD patients, and in 13-100% (median 79%) of SRD patients. Complete or improved ulcer healing was achieved in 33-100% and 25-67% respectively, of all patients. CONCLUSIONS: Thoracic sympathectomy can be beneficial in the treatment of upper extremity ischemia in select patients. Although the effect in patients with PRD will lessen over time, it may still reduce the severity of symptoms. In SRD, effects are more often long-lasting. In addition, thoracic sympathectomy may maximize tissue preservation or prevent amputation in cases of digital ulceration.
