OBJECTIVE

Cervical angina, or pseudoangina pectoris, is a noncardiac syndrome of chest pain that often mimics angina pectoris but is a disease of the spine. Diagnosis of cervical angina can be difficult and is often overlooked, although once identified, it can be successfully managed through conservative therapies and/or a variety of surgical interventions. Ultimately, cervical angina is an important component of the list of differential diagnoses in noncardiac chest pain. In the present study, the authors report the first comprehensive systematic review of the range of cervical and thoracic pathologies associated with cervical angina, as well as the different treatment methods used to manage this condition.

METHODS

A systematic review was performed according to PRISMA guidelines and using PubMed, Web of Science, and Cochrane databases from database inception to April 29, 2020, to identify studies describing spinal pathologies related to cervical angina. The following Boolean search was performed: (“cervical” OR “thoracic”) AND (“angina” OR “chest pain”) AND (“herniation” OR “OPLL”). Variables extracted included patient demographics, cervical angina pain location, pathology and duration of symptoms, treatment and/or management method, and posttreatment pain relief.

RESULTS

Upon careful screening, 22 articles published between 1976 and 2020 met the study’s inclusion/exclusion criteria, including 5 case series, 12 case reports, and 5 retrospective cohort studies. These studies featured a total of 1100 patients, of which 95 met inclusion criteria (mean patient age 51.7 years, age range 24–86 years; 53.6% male). Collectively, symptom durations ranged from 1.5 days to 90 months. Cervical herniation (72.6%) accounted for the majority of cervical angina cases, and surgical interventions (84.4%) predominated over physical therapy (13.0%) and medical management strategies (9.1%). Every patient assessed at follow-up reported relief from symptoms related to cervical angina.

CONCLUSIONS

Cervical angina is a noncardiac syndrome of chest pain associated with a broad range of cervical and thoracic spinal pathologies, the most common of which is cervical disc herniation. Although difficult to diagnose, it can be successfully treated when identified through first-line conservative management or surgical interventions in refractory cases.

OBJECTIVE

Frailty is a clinical state of increased vulnerability due to age-associated decline and has been well established as a perioperative risk factor. Geriatric patients have a higher risk of frailty, higher incidence of brain cancer, and increased postoperative complication rates compared to nongeriatric patients. Yet, literature describing the effects of frailty on short- and long-term complications in geriatric patients is limited. In this study, the authors evaluate the effects of frailty in geriatric patients receiving cranial neurosurgery for a primary CNS neoplasm.

METHODS

The authors conducted a retrospective cohort study of geriatric patients receiving cranial neurosurgery for a primary CNS neoplasm between 2010 and 2017 by using the Nationwide Readmission Database. Demographics and frailty were queried at primary admission, and readmissions were analyzed at 30-, 90-, and 180-day intervals. Complications of interest included infection, anemia, infarction, kidney injury, CSF leak, urinary tract infection, and mortality. Nearest-neighbor propensity score matching for demographics was implemented to identify nonfrail control patients with similar diagnoses and procedures. The analysis used Welch two-sample t-tests for continuous variables and chi-square test with odds ratios.

RESULTS

A total of 6713 frail patients and 6629 nonfrail patients were identified at primary admission. At primary admission, frail geriatric patients undergoing cranial neurosurgery had increased odds of developing acute posthemorrhagic anemia (OR 1.56, 95% CI 1.23–1.98; p = 0.00020); acute infection (OR 3.16, 95% CI 1.70–6.36; p = 0.00022); acute kidney injury (OR 1.32, 95% CI 1.07–1.62; p = 0.0088); urinary tract infection prior to discharge (OR 1.97, 95% CI 1.71–2.29; p < 0.0001); acute postoperative cerebral infarction (OR 1.57, 95% CI 1.17–2.11; p = 0.0026); and mortality (OR 1.64, 95% CI 1.22–2.24; p = 0.0012) compared to nonfrail geriatric patients receiving the same procedure. In addition, frail patients had a significantly increased inpatient length of stay (p < 0.0001) and all-payer hospital cost (p < 0.0001) compared to nonfrail patients at the time of primary admission. However, no significant difference was found between frail and nonfrail patients with regard to rates of infection, thromboembolism, CSF leak, dural tear, cerebral infarction, acute kidney injury, and mortality at all readmission time points.

CONCLUSIONS

Frailty may significantly increase the risks of short-term acute complications in geriatric patients receiving cranial neurosurgery for a primary CNS neoplasm. Long-term analysis revealed no significant difference in complications between frail and nonfrail patients. Further research is warranted to understand the effects and timeline of frailty in geriatric patients.
