Actual Patient Cases of CHD and MI from My Practice
Published in Mark C Houston, The Truth About Heart Disease, 2023
This patient presented with an “atypical” symptom of fatigue that was caused by CHD. The severe blockage in his left anterior descending artery, which supplies about two-thirds of the heart muscle, did not allow adequate delivery of oxygen, blood, and nutrients to the heart muscle. This resulted in a decreased delivery of oxygen, blood, and nutrients to all the arteries in the body, as the heart function was poor. The result of all of this was fatigue. In addition, the fast heart rate and increased blood pressure could be related to the blockage, as they returned to normal after the stent.
Placement of Balloon-Expandable Intraluminal Stents in Iliac Arteries: First 171 Procedures

Juan Carlos Jimenez, Samuel Eric Wilson
One-hundred-eighty-one stents were placed in common iliac arteries and 80 stents were placed in external iliac arteries. Seventeen patients underwent bilateral stent placement and 21 patients underwent stent placement in ipsilateral common and external iliac arteries. Twelve patients underwent stent placement in addition to a surgical outflow procedure.

Corresponding information from the right side of the heart can be obtained by venous catheterisation and this carries a lower risk of vascular complications than arterial catheterisation. The technique may be extended to therapeutic procedures such as angioplasty or stent insertion that are beyond the scope of this article.
Paclitaxel-eluting silicone airway stent for preventing granulation tissue growth and lung cancer relapse in central airway pathologies

Central Airway Obstruction (CAO) occurs as a result of malignant and nonmalignant pathologies affecting the large airways of the tracheobronchial tree and can present with life threatening respiratory symptoms. Tumors are a common cause of CAO but nonmalignant processes, including degradation of cartilaginous rings surrounding the trachea and bronchus; otherwise known as tracheobronchomalacia (TBM) can also arise [1]. In many cases of CAO, airway stents are required to achieve and maintain lumen patency. Stents are cylindrical or Y-shaped flexible tubes placed into patient’s respiratory tract to ensure that airways remain unobstructed to allow airflow with respiration. The primary function of airway stents is to exert radial forces to maintain luminal patency, overcoming the extrinsic force or central obstruction that is the cause of loss of airway structure. Patients who undergo successful stent insertion experience relative relief from the symptoms associated with CAO including dyspnea, stridor, cough, and hemoptysis from the tamponading effect of stents on airway vessels [2].

There are different types of stents for different situations. We usually use silicon stent for benign medical situations, which we can easily remove (such as, Dumon stents). There are metallic stents, covered or not covered depending on the medical situation and polyurethane stents. Again, the type of stent depends on the medical situation that we have to treat and on the length of local treatment. Metallic stents have been used in the past but have a high complication rate and are difficult to remove. Small polymer stents are thick walled and therefore difficult to place and have a high rate of mucus plugging. Silicon stents have also a high rate of mucus plugging but less than the polymer stents [8,9]. Silicon stents are more difficult to insert, however, easier to remove. Having the necessary rigid bronchoscope equipment is absolutely necessary for the silicon placement and removal.
Benign biliary strictures treated with biodegradable stents in patients with surgically altered anatomy using double balloon enteroscopy

There were no stent or cholangiography related adverse events e.g., perforations or bleedings, but one patient required endotracheal intubation for nose bleeding caused by the placement of nasopharyngeal tube. The Archimedes stents were easily deployed through the long working channel (200 cm) of the DBE, and the visibility in fluoroscopy was good (Figure 3). There are three types of stents varying from the degradation profile (fast, medium and slow degrading) available, which enables the use for different indications. There are also wide selection of diameters and lengths of these stents. The only deficiency seems to be quite short expiration time. In a pilot study of 53 patients with conventional ERCP these stents have found to be safe and efficacious in the treatment of biliary and pancreatic duct obstructions [9].
