A Case of a Coexisting Aldosterone-Producing Adrenal Adenoma and Ipsilateral Renal Artery Stenosis / 대한내과학회지

The simultaneous occurrence of renovascular hypertension and an aldosterone-producing adrenal adenoma is a rare entity. Here, we report the case of a 52-year-old female who had a coexisting aldosterone-producing adrenal adenoma and ipsilateral renal artery stenosis. She was diagnosed with the aldosterone-producing adrenal adenoma and then underwent a laparoscopic left adrenalectomy. Her blood pressure was uncontrolled after the adrenalectomy. Selective renal angiography showed left renal artery stenosis; thus, she underwent balloon angioplasty at the same sitting. Subsequently, her blood pressure returned to normal after administration of a single antihypertensive drug. This case suggests that it is important to recognize the possible coexistence of renal artery stenosis in a patient with an aldosterone-producing adrenal adenoma.

Electrolyte Imbalance in Patients with Sheehan's Syndrome

BACKGROUND: We investigated the prevalence of electrolyte imbalance and the relationship between serum electrolyte and anterior pituitary hormone levels in patients with Sheehan's syndrome. METHODS: In a retrospective study, we investigated 78 patients with Sheehan's syndrome. We also included 95 normal control subjects who underwent a combined anterior pituitary hormone stimulation test and showed normal hormonal responses. RESULTS: In patients with Sheehan's syndrome, the serum levels of sodium, potassium, ionized calcium, magnesium, and inorganic phosphate were significantly lower than those in control subjects. The prevalence of hyponatremia, hypokalemia, hypocalcemia, hypomagnesemia, and hypophosphatemia in patients with Sheehan's syndrome was 59.0% (n=46), 26.9% (n=21), 35.9% (n=28), 47.4% (n=37), and 23.1% (n=18), respectively. Levels of sodium and ionized calcium in serum were positively correlated with levels of all anterior pituitary hormones (all P<0.05). Levels of potassium in serum were positively correlated with adrenocorticotrophic hormone (ACTH) and growth hormone (GH) levels (all P<0.05). Levels of inorganic phosphate in serum were positively correlated with levels of thyroid-stimulating hormone, prolactin, and GH (all P<0.05), and levels of magnesium in serum were positively correlated with delta ACTH (P<0.01). CONCLUSION: Electrolyte imbalance was common in patients with Sheehan's syndrome. Furthermore, the degree of anterior pituitary hormone deficiency relates to the degree of electrolyte disturbance in patients with this disease.

Reverse Controlled Antegrade and Retrograde Subintimal Tracking in Chronic Total Occlusion of Right Coronary Artery

Passage failure of guidewire is still remained most common reason for percutaneous coronary intervention (PCI) failure in chronic total occlusion (CTO). Intravascular ultrasound study (IVUS) and cardiac CT angiography can help identify features that most influence current success rates of PCI. We report our experience using the reverse controlled antegrade and retrograde subintimal tracking technique under the aid of IVUS, cardiac CT angiography for an ambiguous CTO of proximal right coronary artery.

Below the Knee Intervention Using Multidisciplinary Methods Including an Antegrade, Retrograde Approach Without the Use of a Sheath but With a Plaque Excision Device

Below the knee (BTK) interventions are increasing in patients with rest pain or critical limb ischemia, and these interventions are frequently successful in facilitating limb salvage. New intervention techniques and devices allow successful recanalization of occluded BTK arteries. Here, we report a case of successful recanalization of BTK arteries using multidisciplinary methods, including an antegrade approach and retrograde approach without the use of a sheath, but with simple balloon angioplasty, and plaque excision using Silverhawk atherectomy device.

A Case of Gastric Intramural Hematoma after an Epinephrine Injection for Gastric Ulcer Bleeding in a Patient Medicated with Aspirin / 대한소화기내시경학회지

An intramural hematoma of the stomach usually results from trauma. Gastric intramural hematomas may also occur in patients with bleeding disorders who are receiving anticoagulation therapy or after an endoscopic procedure. Here, we describe a case of a gastric intramural hematoma after endoscopic hemostasis for gastric ulcer bleeding in a patient medicated with aspirin.

Hypertensive Heart Failure Associated with Middle Aortic Syndrome Reversed Dramatically by Endovascular Management

A 42-year-old male patient presented with refractory hypertension and congestive heart failure. He had taken hydrochlorthiazide 50 mg, carvedilol 25 mg, diltiazem 180 mg, and losartan 100 mg per day. Aortogram revealed a severe luminal narrowing in the distal thoracic aorta with a peak systolic pressure gradient of 60 mmHg across the lesion. Endovascular management was performed with 22 x 80 mm self-expandable Nitinol-S stent after predilation with 10 x 40 mm balloon. After endovascular management, the patient's blood pressure, left ventricular ejection fraction (LVEF) and dilated LV dimension were remarkably improved.
