Contemporary Management of Patients with Concomitant Coronary and Carotid Artery Disease

Mun J. Poi; Angela Echeverria; Peter H. Lin

The ideal management of concomitant carotid and coronary artery occlusive disease remains elusive. Although researchers have advocated the potential benefits of varying treatment strategies based on either concomitant or staged surgical treatment, there is no consensus in treatment guidelines among national or international clinical societies. Clinical studies show that coronary artery bypass grafting (CABG) with either staged or synchronous carotid endarterectomy (CEA) is associated with a high procedural stroke or death rate. Recent clinical studies have found carotid artery stenting (CAS) prior to CABG can lead to superior treatment outcomes in asymptomatic patients who are deemed high risk of CEA. With emerging data suggesting favorable outcome of CAS compared to CEA in patients with critical coronary artery disease, physicians must consider these diverging therapeutic options when treating patients with concurrent carotid and coronary disease. This review examines the available clinical data on therapeutic strategies in patients with concomitant carotid and coronary artery disease. A treatment paradigm for considering CAS or CEA as well as CABG and percutaneous coronary intervention is discussed.

Objectives Thoracic outlet syndrome, a condition commonly reported in adults, occurs infrequently in the pediatric population. The objective of this study was to assess the outcome of surgical interventions of thoracic outlet syndrome in pediatric patients. Methods Clinical records of all pediatric patients with thoracic outlet syndrome who underwent operative repair from 2002 to 2015 in a tertiary pediatric hospital were reviewed. Pertinent clinical variables and treatment outcomes were analyzed. Results Sixty-eight patients underwent a total of 72 thoracic outlet syndrome operations (mean age 15.7 years). Venous, neurogenic, and arterial thoracic outlet syndromes occurred in 39 (57%), 21 (31%), and 8 (12%) patients, respectively. Common risk factors for children with venous thoracic outlet syndrome included sports-related injuries (40%) and hypercoagulable disorders (33%). Thirty-five patients (90%) with venous thoracic outlet syndrome underwent catheter-based interventions followed by surgical decompression. All patients underwent first rib resection with scalenectomy via either a supraclavicular approach (n = 60, 88%) or combined supraclavicular and infraclavicular incisions (n = 8, 12%). Concomitant temporary arteriovenous fistula creation was performed in 14 patients (36%). Three patients with arterial thoracic outlet syndrome underwent first rib resection with concomitant subclavian artery aneurysm repair. The mean follow-up duration was 38.4 ± 11.6 months. Long-term symptomatic relief was achieved in 94% of patients. Conclusions Venous thoracic outlet syndrome is the most common form of thoracic outlet syndrome in children, followed by neurogenic and arterial thoracic outlet syndromes. Competitive sports-related injuries remain the most common risk factor for venous and neurogenic thoracic outlet syndromes. Temporary arteriovenous fistula creation was useful in venous thoracic outlet syndrome patients in selective children. Surgical decompression provides durable treatment success in children with all subtypes of thoracic outlet syndrome.

Infrared thermography in the diagnosis and management of vasculitis

Peter H. Lin; Angela Echeverria; Mun J. Poi

Vasculitis is a clinical condition with associated diagnostic challenges due to nonspecific symptoms and lack of a confirmatory imaging modality. We report a case of a 39-year-old female patient who developed generalized malaise, lethargy, and headache. Laboratory evaluation showed elevated inflammatory markers. Conventional imaging studies including computed tomography and carotid duplex ultrasound were unremarkable. Infrared thermography revealed enhanced thermographic signals in the left carotid artery and aortic arch. Corticosteroid therapy was commenced, and the patient responded well. Follow-up infrared thermography at 6 months showed complete resolution of the thermographic pattern, and the patient remained symptom free.

differences across the specialties. A total of 43% (157 of 368) of total cases involved death of the patient. Among the four specialties, there was a significant (P 1⁄4 .0004) difference in the primary allegation (informed consent, preprocedure negligence, intraprocedural complications, or postprocedural complications) underlying the litigation (Fig). For CTS and VS, there was a predominance of informed consent and preprocedure negligence allegations (70% [7 of 10] and 52% [28 of 54] respectively). Intraprocedural negligence was the most common allegation for IR (59% [23 of 39]), while allegations were more evenly distributed among IC. Conclusions: Key issues were identified regardingmalpractice litigation involving the specialties that commonly perform endovascular procedures. Despite the increasing number of ICs doing peripheral interventions, a largemajority of IC cases were related to coronary treatments. A surprisingly large percentage of VS cases were related to seemingly minor cases. There were significant interspecialty differences in the primary underlying allegations. As the scope of endovascular procedures broadens and deepens, it is important for clinicians to be aware of the legal considerations relevant to their practice.

Introduction: Laparoscopic insertion of peritoneal dialysis (PD) catheter has become a preferred method compared to the traditional open technique for PD catheter insertion. We retrospectively report the outcome of 1-port laparoscopic placement PD catheters in our institution. Methods: A total of 263 patients with end-stage renal disease who underwent single-trocar laparoscopic PD catheter insertion during a recent 6-year period were reviewed. Laparoscopic technique involves introducing a PD catheter over a stiff guidewire into the abdominal cavity through a 10-mm laparoscopic port. Pertinent clinical variables, procedural complications, and follow-up outcome were analyzed. Results: There were 182 men and 81 women. The mean age was 56 years. Technical success was 95.8%. Catheter occlusion was the most common early complications (<6 months) that occurred in 4 (1.5%) patients. Late complications (> 6 months) including catheter occlusion, cuff extrusion, catheter leakage, catheter migration, infection, and hernia occurred in 5 patients (1.9%), 2 patients (0.8%), 3 patients (1.1%), 3 patients (1.1%), 6 patients (2.3%), and 4 patients (1.5), respectively. Mean follow-up time was 39 ± 18 months. Catheter survival rate at 1, 2, 3, 4, and 5 years was 96%, 94%, 90%, 85%, and 82%, respectively. Conclusion: Laparoscopic PD catheter implantation via a single-trocar utilizing a stiff guidewire technique is feasible and safe. This method can result in low complication and high catheter survival rate.

Angela Echeverria; Zvonimir Krajcer

Steroids if taken chronically or periprocedurally contribute to delayed wound healing and decreased vascular patency Access site complications after diagnostic interventional procedures carry significant morbidity, increased cost, and prolonged hospital stay TAVI offers high risk surgical candidates with severe aortic stenosis a significant survival advantage

Zvonimir Krajcer; Angela Echeverria

Spinal cord ischemia (SCI) has been one of the most concerning complications after surgical and endovascular thoracoabdominal aortic aneurysm repair “Open Branch” is an innovative technique to reduce the incidence of SCI Further studies in a larger number of patients with varying pathologies are needed to confirm the advantages of this technique

Impact of Glycoprotein IIb/IIIa Inhibitors Use on Outcomes After Lower Extremity Endovascular Interventions From Nationwide Inpatient Sample (2006–2011)

Angela Echeverria; Zvonimir Krajcer

Anticoagulant and antiplatelet medications are necessary in peripheral endovascular intervention, but a standardized approach has not yet been established. Glycoprotein IIb/IIIa inhibitor use in endovascular lower extremity interventions decreased overall amputation rates. Glycoprotein IIb/IIIa inhibitor use in endovascular lower extremity interventions increased postprocedural bleeding and complications requiring intervention.
