Time-resolved dynamic computed tomography venography (CTV) of the lower limbs – using ultra-low dosage of contrast media: a case report

One of the most unusual complications in cholethiasis is spontaneous cholecystocutaneous fistula, which has only been reported a few times in the literature. We report the case of a 76 year old man who presented with a right hypochondrium subcutaneous abscess, with pain evoked through palpation. No comorbidity in the patient’s medical history were noted. Confirmation of cholecystocutaneous fistula was made using the proper diagnostic process, which is computed tomography with contrast media, followed by hepatobiliary MRI. This confirmed the presence of a fistulous pathway between the gallbladder and the skin. The patient underwent cholecystectomy surgery and open laparotomy with en block aponeurotic muscle, skin and fistula orifice excision.

The incidence of contrast media extravasation has been increasing gradually. Most contrast media extravasations only can cause pain, swelling and erythema. However, in more severe cases, skin necrosis, ulceration, or compartment syndrome may occur, often necessitating a surgery. Early diagnosis and treatment should be established on the spot in order to avoid such a severe damage. We present a case of 42-year-old woman with a compartment syndrome in the right upper extremity caused by extravasation of computed tomography contrast media.

Computed Tomography Venography

SummaryIndirect computed tomography (CT) venography reportedly provides high accuracy for detection of venous thrombosis in patients suspected of pulmonary embolism (PE). Nevertheless, the extent of the scanning range for lower limb and abdominal veins remains to be determined. It was the objective of this study to investigate the distribution of venous thrombosis in order to identify the most appropriate extent of scanning range when using CT venography. We reviewed 1,408 combined CT pulmonary angiographies (CTPA) and indirect CT venographies of the lower limbs, performed in patients suspected of PE. Percentage of venous thromboembolism (VTE), which includes PE and/or venous thrombosis was calculated. Location and the upper end of clots were recorded in 37 venous segments per patient from calf to diaphragm. PE, venous thrombosis and VTE, were found respectively in 272 (19.3%), 259 (18.4%) and 329 (23.4%) patients. Addition of CT venography to CTPA increased depiction of VTE in 17.3%.The upper end of venous thrombosis was located below the knee in 48%, between knee and inguinal ligament in 36% of the patients, and above the inguinal ligament in 15%.Ninety-six patients had thrombosis in a single vein, of which none occured above the iliac crests in a patient without PE at CTPA. In conclusion, when added to CTPA, optimal scanning of CT venography should extent from calves to the iliac crests in patients suspected of VTE.

Dynamic Time

Runoff computed tomography angiography (CTA) is commonly used to diagnose peripheral artery disease (PAD) of the lower extremities. However, the risk of non-conclusive examination due to suboptimal timing and overrunning the contrast medium bolus is a major pitfall that must be considered. Here we describe two case studies using dynamic time-resolved CTA imaging of the peripheral vascularity.
