Summary
Extra-Intracranial (EC-IC) bypass surgery is safe and effective for patients 70 and older, showing similar complication and patency rates compared to younger individuals. Age is not the primary factor in determining EC-IC bypass suitability.
Area of Science:
- Neurosurgery
- Vascular Surgery
- Geriatric Medicine
Background:
- Extra-Intracranial (EC-IC) bypass surgery addresses hemodynamic insufficiency and cerebral ischemia.
- An aging population increases the incidence of conditions requiring EC-IC bypass.
- Evaluating EC-IC bypass outcomes in elderly patients is crucial.
Purpose of the Study:
- To analyze complications and patency rates of EC-IC bypass in patients aged 70 years and older.
- To compare these outcomes with a younger cohort (<70 years).
- To determine the efficacy and safety of EC-IC bypass in the elderly population.
Main Methods:
- Retrospective review of patient charts for diagnosis, presentation, bypass type, and outcomes.
- Comparison of 17 patients (≥70 years) with 158 patients (<70 years) who underwent arterial bypass.
- Assessment of medical/surgical complications and graft patency rates (postoperative and follow-up).
Main Results:
- No significant differences in overall medical and surgical complication rates between older and younger patients.
- Similar direct postoperative and follow-up graft patency rates (88.2% older vs. 88.3% younger).
- Younger patients were more likely to undergo bilateral bypass (28.1% vs. 0%; p=0.01).
Conclusions:
- EC-IC bypass is safe and effective in patients aged 70 years and older.
- Outcomes are comparable to younger patients, suggesting age is not the sole determinant of benefit.
- Further research should explore factors beyond age for patient selection.

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
