Insights

Cimino fistulas for hemodialysis can rarely cause venous hypertension, leading to finger swelling and ulcers. Surgical treatment involved selective ligation of affected finger tributaries without closing the fistula.

Area of Science:

  • Vascular Surgery
  • Nephrology
  • Dialysis Access

Background:

  • Cimino fistula is a common arteriovenous anastomosis for chronic hemodialysis.
  • Potential complications include thrombosis, infection, and vascular issues.
  • Venous hypertension is a rare but serious complication.

Observation:

  • A case of Cimino fistula complicated by venous hypertension is presented.
  • The patient exhibited pigmentation, swelling, and ulceration of the middle finger.
  • These symptoms were attributed to elevated venous pressure.

Findings:

  • Surgical intervention was performed to address the venous hypertension.
  • The treatment involved selective ligation of venous tributaries supplying the affected finger.
  • The arteriovenous fistula itself was preserved.

Implications:

  • This case highlights a rare complication of Cimino fistulas.
  • Selective ligation offers a potential treatment option for localized venous hypertension.
  • Preserving the fistula is crucial for continued hemodialysis access.

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Varicose Veins I: Introduction

Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Veins of Upper Limbs01:17

Veins of Upper Limbs

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
